Problems with the Electrical System
When work is over, people want to relax and unwind in the cabin of their truck, but the faulty electrical system of the Sierra is making that nearly impossible.
Here’s one Edmunds review worth reading, “Stereo has already stopped connecting to Bluetooth. Dealer says it needs [to] get replaced. For some reason GMC only allows you to view text messages with android auto or apple car play and wait it gets better you have to plug your phone into a USB cord to do this? Which defeats the charger in the counsel that you just set your phone on? Either way I’ve been a Chevy/GMC guy for 30 years I put a lot of road miles on and buy a new truck every two to three years and for the first time I can’t wait to trade this turd in for something else. If you want tech this isn’t the truck for you.”
It turns out that there are more problems than most people know. In fact, there is a class-action lawsuit related to the defective seven-inch infotainment systems that aren’t built right. Additionally, there’s a massive recall that is quite dangerous. NHTSA Campaign Number 19V888000 states that the battery positive cables might have too much glue on them, causing a poor connection with the alternator that could cause the vehicle to stall or create arching, which could turn into a truck fire. While GMC Sierra drivers tend to be rough and tough, surviving a truck fire might be asking too much. Maybe it’s time for this lineup to go up in smoke once and for all.
Problems with the Powertrain
To haul and tow heavy loads, a truck must be equipped with a reliable powertrain, but that’s not the case with the Sierra pickups.
Here’s another Edmunds review to read. “I bought a new 2019 GMC Sierra 1500 in Oct 2019. It was a very costly mistake. The dealers are aware this truck has tranny problems that cannot be fixed. After 6 trips to the dealer the tranny problems are still there. There is a class action law suit against GM. This truck has 2700 miles on it and I traded it to get out if this nightmare.”
Should it surprise anyone that there is a recall for the powertrain too? NHTSA Campaign Number 20V650000 states that some models have driveshaft joints that weren’t welded correctly. The driveshaft could separate, leading to a loss of propulsion and possible crash. If only it could throw itself off a cliff, never to be seen from again, there are some customers that would probably rejoice.
Problems with the Service Brakes
Among all of the other problems, it’s vital that this truck comes with reliable brakes for maximum stopping power. Yet, that seems to be an issue too.
Here’s an complaint left on the Edmunds site. “I leased a 2019 GMC AT4 Crew Cab. Factory 2 inch lift with 18″ rims and the Goodyear Wranglers. After driving the truck for approx. 100 miles there was a horrible whirling or whipping sound from front driver side. Also, a disturbing rumbling sound under the passenger seat. As usual, the dealer said it was tire noise! It was more of an axle, front end noise. They allowed me to return the truck.. So I got the 2019 Sierra Denali. I hit 5000 miles and lost my brakes!!! Similar to other forums. I had no braking power unless I pushed the pedal to the floor. UNACCEPTABLE GM!”
Surprise! There’s another recall; this time for the brakes. NHTSA Campaign Number 19V889000 deals with more than 460,000 vehicles with an Electronic Brake Control Module software error that disables the ABS and ESC unexpectedly. Of course, these concerns can also lead to an accident, which is about the only thing the Sierra lineup appears to be good at.
Problems with the Engine
If anyone was expecting a lot from the engine in the Sierra trucks, they are probably still waiting for something magnificent.
Here’s an example of the defective engine from an Edmunds review. “I’ve waited well over 2yrs to purchase a new [truck]. After a few years of researching, saving, planning, I take the plunge. I purchased the 2019 GMC SIERRA 1500 SLE on Monday July 1, 2019 and under 100 miles the dreadful ‘Check engine light’ comes on! First thing in the morning, July 2, I go to the local dealer and they don’t see anything wrong. They state, ‘It could be because it hasn’t been driven in awhile.’ They reset the light and off I go.
By the end of the day 35miles later, the check engine light is back on. The service dept sends me an hour away to Birmingham. After several hours of waiting, the mechanic states, “The water pump is bad.” It is currently at the shop. It is unexpected as to when I will get the truck back but I already have a fear of the dreadful check engine light reappearing because it’s obvious something is SERIOUSLY wrong with this vehicle.”
If the defective engine were to create an accident, it’s important to know that the air bags might not work correctly. NHTSA Campaign Number 18V868000 talks about the passenger front air bag that was likely damaged during assembly, causing it to not inflate during a crash. Until GMC fixes the problem, owners might want to be careful who they put in the passenger side seat. Too bad they can’t take the IRS auditor for a ride.
Problems with the Steering
Controlling the GMC Sierra on the road tends to be a big problem too.
Here’s one more Edmunds review worth reading, “The truck rattles like a 1955 Studebaker, the dealer cannot resolve the problems.”
To show how defective this truck truly is, one only needs to look at the tires, which also suffer from a recall. NHTSA Campaign Number 21V4230000 states that the over cured tires put on the Sierra can suffer from a break in the sidewall causing separation and complete air loss. The only thing GMC has proven to be “professional grade” at is as a lemon.

They call me and explain it will cost ,000 to repair. The service writer explains to me that they have 4 of these each week come into the shop. It is so common that they keep the parts in stock to repair. While I was waiting in the waiting room another person came in with the exact same problem.

| Description | While driving on the highway, I got a message that said "low oil pressure, turn off engine" with red flashing lights. I could also smell burning oil and metal. I immediately pulled over and turned off my engine. When I exited my truck, I could see all of the oil that remained in my engine leaking onto the ground. My truck was towed to a local repair shop and they advised me that this is a common problem in this truck. The oil line blew likely due to a defective crimp. The mechanics can't repair the problem right away because this line is on a national backorder and there is no aftermarket option. This obviously happens too often if this part is on backorder. The mechanics believe there may have been damage done to the engine as a result of losing all of the oil on the highway. |

| Description | Driver seat belt would not recoil. Took to royal gmc of tucson and they said it was not a warranty covered part and would not repair it unless I paid for the seat belt replacement. Obviously, I need a seat belt as a safety feature being the driver so I had them order the seatbelt and they installed it. See attached receipt. I believe this should be a warranty item from the manufacturer as it is defective and a serious safety issue. The vehicle is a 2019. I am the only one that drives this vehicle and I have never had any accidents etc. |

They have stated this is a common problem with this vehicle and they had a lot of these vehicles come in with the same exact problem. Vehicle had no power, engine lights on and valve failure after being replaced before and the vehicle has less than 60,000 miles at 2nd failure. They stated the 1st repair has no warranty to cover such a catastrophic failure and I must pay out of pocket. I argued that it shouldn't have failed with less than. 60,000 miles any expectations of engine failure would be with massive miles and would be expected for some form. Of major over haul. Caused emergency as I was in the middle of the interstate upon failure and I almost lost my life. I asked who was performing the repair and they won't answer the request about the repair. They stated it was sent out for repairs and not an in house repair. All repairs have been at gm certified center. |

| Description | The rear window on the 2019 gmc sierra slt leaks water into the cab. This presents a serious concern to the owner of the vehicle because unless you are specifically looking for the leak you may not even know there is one. Upon noticing the leak, one can witness a steady drip of water behind the rear seat, drivers side. My personal concern is that what happens after the water has leaked and had gone unnoticed for an extended period of time, does mold start to grow? Does my truck have mold growing in it? With two young children in the vehicle I am concerned about their health and safety. My frustration with this issue is that gm refuses to acknowledge that there is an issue. My dealer has brought this issue up with gm but the claim has been denied. I have no idea how long the leak has been happening but it's a manufacturing problem that exists and it certainly shouldn't be the owners responsibility to fix the problem. More importantly, it shouldn't be my young childrens health that is affected by the manufacturers incompetency and ignorance. |

| Description | The rear window defogger is smoking and sizzling. The connection on the passenger side glass that connects the moveable harness for the center glass smokes and sizzles when the rear defogger is on. There is a recall on these vehicles in canada for this issue. My concern is that it may start a fire. The connector is right behind the right rear passenger seat, imposing a threat to the occupant of that seat. Also, the rear defogger comes on automatically with heated mirrors when remote started. I cannot use remote start, mirror defogger, or rear glass defogger currently due to this defect. I noticed a sizzling sound while driving the truck. I pulled over and began searching. I found smoke being emitted from the connector attached to the rear glass on the passenger side. This is a serious issue. It is a fire hazard. The vehicle could catch fire while driving or while remote engine start has been activated in temperatures lower than 40 degrees. There is a difference in an uncommon electrical short and a known problem. General motors is aware of this issue and there has not be a notification to owners in the united states nor are there any recalls or suggested repairs. The safety of consumers is in jeopardy with this known problem occurring in multiple lines of their vehicles. Any with a power sliding glass could be affected. |

| Description | I was on the highway going 60mph and the engine light came on and it said “low oil pressure, turn off engineâ€. I could not safely pull over and had to drive a half mile to do so. The vehicle was towed to the service station near my house that I've used before and the problem was a blown high pressure oil line. Technician said that the hose came undone at the crimp joint and that he's recently seen other sierras with the same problem. I checked my gmc app and there were no recalls so I authorized the repair and paid the 9 bill. A few days later I did a google search for 2019 gmc sierra oil line problems and got several hits from the gmauthority. Com site. It's a known problem in canada and alaska (cold weather) and gmc will repair it at no charge if the vehicle was bought there and the repair is done by a gmc repair facility but they won't reimburse me because I bought mine in ma. It was 24 degrees the day the line blew. The problem is that the part is faulty and fails at cold temperatures. There should be a recall on the high pressure oil lines for all vehicles sold in cold weather states. |

| Description | The truck has 50,000 miles, purchased new. I don't tow or go off road. I take it to the dealer every 5,000 miles. While driving 65-70mph on the interstate (4-lanes), my dash lit up with five messages and the "brake, traction control and engine" lights illuminated. I applied brakes but the pedal went to the floor and the steering veered to the left causing me to move out of my lane. The truck then went to limp mode and I was unable to go above 43mph the remainder of the trip home. After taking it to my dealer the next day, I was told they "found air in the brake fluid system due to secondary seal failure in brake master cylinder, and was quoted a new cylinder (pn 86788482) for 08. 06. Response to questions: >component failure: brake master cylinder (eboost brake unit assembly) / brake system failure >it was just me in the vehicle - brake failure on the highway put me and others on the road at major risk >yes - after paying to diagnose, I was told this was brake master cylinder failure. ...

| Description | I purchased a 2019 gmc certified 2500 diesel truck with 48000 miles I started getting alerts on my dash stating trailer brake system over and over. I would press the dismiss button but it would not stop from appearing and dinging over and over. I took vehicle to dealer ship since I have remaining bumper to bumper and extended warranty coverage. To my dismay I find out the dash trailer brake system switch is faulty. Good thing I had an extended warranty since the bumper to bumper does not cover electrical. While truck was still under warranty the same alert came on but the gmc dealership did not find and issues. I feel the trailer brake system was defective from the start. I am being force to pay over 0. 00 out of my pocket since my extended warranty did not cover the entire cost. Shame on you gm for putting cheap quality parts on expensive trucks... |

The 17" spare tire provided with the vehicle was not compatible for use with the accessory wheels, which can cause the anti-lock brake system (abs) to not function properly under certain conditions. As a result, the contact was concerned that the abs could potentially fail on his vehicle. The vehicle was not diagnosed or repaired. The manufacturer was notified of the concern and the contact was advised to call the nhtsa hotline. The contact had not experienced a failure. |

These trialers test fine in other trucks and with meters. The trailer brake controller does not work. There are many owners reporting the same thing. It is a critical safety feature to stop the truck & trailer and probably already has led to some fatalities. Please issue a recall. Thank you. |

| Description | While driving down the highway at 70 mph, the transmission slammed into gear and the engine died. A message appeared and said shift to neutral and press the ignition button. The check engine light also appeared. This had been a problem that first appeared at 48,000 miles. I was told that gm recognizes that there is an issue with the transmission, but that it would not damage the vehicle so it is not able to be repaired under warranty. The dealership advised that I should change the transmission fluid, so I did. The transmission continued to slam into gear thereafter. Fast forward to 55,000 miles where the truck completely died. The engine would not start and the truck had to be towed to a dealership. The next day the dealership told me that they had figured out the issue and that it was related to the fuse box and the ignition. I picked up my truck the next day, and drove less than a mile before the engine died again. I sat at the dealership for 12 hours and they had another answer for what was happening. They said that the shift lever was damaged and it was not allowing the battery to recharge. I live 400 miles away from where the truck broke down. I had to rent a vehicle to return home with my family from a trip. I now have to drive back to my truck in another state, and pay for the 12 plus hours of diagnostic work at 0 an hour as well as the cost of the part and the time to install it because the dealership stated that this is not covered by any warranty. I see that several people are dealing with a similar issue and I am frustrated that no one is willing to help us right this wrong. My grandfather worked for gm his entire adult life, and I will never own another one. |

| Description | Last weekend was taking the kids and my brother and his son fishing, so 2 adults in front seats 3 kids on the backseat. Got my boat all hooked up and we're off. About 2 miles down the road the truck rebs up really high and then bottoms down hard on the rpm's. As soon as this happens all lights and instrument cluster goes crazy. Check engine light on, parking brake light on,traction control light on, and I'm sure I'm forgetting more. The cluster states esc failure drive with caution, do not exceed 43 miles per hour speed limit brake failure and so on. I have since found pictures pf the exact same thing that happened to me that morning and will provide. Needless to say I have no brakes and have a 19 ft bass boat behind me. All I could do was let off gas completely and push brake pedal all the way to the floor and pray that it stopped. Good lord willing it did. Pulled over asap and killed truck, let sit a few minutes while I assessed the situation and cranked it back up. All lights and brakes were fine. Has not done it since but I only drove to dealership to find out the issue and 4 days later still no answer. Its a 2019 with only 26000 miles, and has never had 1 issue before this |

| Description | The sockets in the rear brake lights had excessive corrosion and was causing the terminals on the bulbs to deteriorate. The lights were malfunctioning in all situations from braking, turn indicator and running lights. I was notified by the system that there was a problem. After trying to resolve the problem and replacing the bulbs the condition only worsened. I was then pulled over by law enforcement that told me I had nearly no rear lights at night. After banging the plastic light frames I was able to make it home. I brought my truck into the dealer who inspected and found faulty wiring from what I was told. I them paid to have both rear harness change and all the bulbs replaced to repair the condition. After review of the repair the dealer made no additional precautions to ensure that this condition would not return by placing any type of waterproofing dielectric grease in the sockets or connectors. So was this faulty wiring or simply a known defect. The dealer had them in stock which was surprising since I figure they would need to be ordered. |

Have take in to gregg lair in amarillo tx and they have reset shift points to no avail. I talked to head service writer and he stated that gm had a problem with their transmission but did not have a remedy for them. He advised to drive for about 3,000 miles and we have and still have the issue. We have been back multiple times and gregg lair states that it is still in learn mode after over 10,00 miles. I am a mechanic by trade and in my opinion there is a design flaw with the transmission and/or they have the wrong transmission fluid for the design. |

| Description | The 2019 gmc sierra I own shifts extremely hard from a stopped position or when changing from reverse to drive. The shift is so forceful, that it feels like I have been struck by another vehicle. The overall feeling is that the vehicle is not safe to drive and it is not a reliable mode of transportation. The delayed shift, vibration and jerk, makes this vehicle a hazard to drive, as the ability to predict the issue is impossible. There are no other warning lights, or messages prior to the error. Online forums show this to be a known issue. |

| Description | While driving on a two lane road I proceeded to pass a slow moving vehicle, after accelerating from 45 mph to 60 mph my check engine light, service electronic stability control (esc) and service electronic brake system lights illuminated on my display. My rpms increased before shifting gears and I noticed a significant loss in power. Thankfully there was not an accident when the incident occurred; however, if an oncoming vehicle or bad weather it could have been a different outcome. I took my vehicle to a gmc dealer to diagnose the issue where I found out my lifters for my valves are bad and my fourth cylinder is inoperable along with a bad cam. A new vehicle at 65k miles on it should not be having mechanical issues that can pose a danger while driving, putting others and my safety at risk. Gm needs to reevaluate the products and materials their using to build engines to ensure there are no flaws starting with the valve lifters. |

There were no tire pressure or other warnings displayed on the dash of the truck. After pulling over, we discovered the entire side of the tire had completely blown (large holes over the entirety of the wall of the tire). It was not until a minute or two after the tire blew that the truck displayed a low tire pressure warning. After researching the tire maker's website, I discovered a recall for the exact tire however, the date as listed on the dot number was one week off. Our tires should have also been included in the recall as the description of the tire maker's defect was exactly as it occurred when our tire blew out. |

| Description | While driving the vehicle 21oct2020 it started whining and jerking. I called the dealership to have it checked they couldn't see us, so we took it to a different gmc dealership that said the codes had not been updated, they preformed the recall and said it should be fine. Two days later it started jerking again and shut off when stopped at a light. I took it to the gmc dealership we bought it from on the 28oct2020 and I was told that the truck was fine, and that the diagnostics showed no problems whatsoever. The tech said he would drive it out of the bay, if brittany would open the door and before he could drive it through the garage bay area and out the garage bay door the truck made a crazy loud noise, jerk to a sudden stop and the transmission went out, and the truck would not restart at all and had to be towed out of the bay door. The 2019 truck has had 5 recalls for safety issues and with 40,000 miles the transmission went all the way out and the truck has been sitting there at the dealership for over a month waiting on the new transmission to come from gmc. I go in and see the transmission recall on so many 8 speed transmission which this truck has, and now I feel like I was sold a lemon and no one seems to care. % recalls and the transmission goes out completely at 40,000 miles. I am so upset about it that I do not even want the truck anymore. It is going to ruin my resale value and the lemon law should apply on a truck one year old. I have filed complaints with the dealership, and now on their front door is a sign that says they will not honor the warranty policies on any vehicle they sold after november 15, 2020. Of course they sold me zurich extended warranty too, and I can promise I will never buy gmc again. I also have a 2017 pathfinder almost paid off, that I am giving to my daughter, and I was going to get an gmc arcadia but not a chance now. |

| Description | First feeling was, I was driving in a parking lot going maybe 5 miles an hour and I felt a vibration in the brake pedal. Pulled onto the main road and approached a stop light when the truck stopped a little hard as I was depressing the brake pedal. As I started pressing on the gas when the light turned green, I was traveling around 35 mph or so, when the truck came to a complete stop in which myself & passenger were slightly thrown forward due to the abrupt stop for no apparent reason. The vehicle in back of me nearly rear ended me due to the abrupt stop the truck did. I immediately contacted the dealer, in which after several days in the shop, the dealer told me that gmc knew about this particular issue but has not issued a recall. The dealer was instructed to replace the transmission control module, due to a malfunction in the tcm that apparently was trying to shut the truck down completely. Therefore causing the truck to stop abruptly with no warning. |

| Description | While truck was parked (engine was not running at all), I used the key fab remote to unlock the truck and then open the tailgate. At this time, the tailgate slammed open (very forcefully and quickly) and hit my son in the chest. This has also happened while the truck was running and in park. At that time, I (the driver) pushed the button on the center dash to open the tailgate so that my young son could put his baseball gear in the bed of the truck. Again, the tailgate opened very quickly and abruptly, slammed open, and the heavy tailgate hit him in his body. The tailgate is supposed to open slowly and gradually, not slam open. Thankfully, my son was not seriously injured. The remote control, slow opening tailgate was one of the selling features of the truck, and now the tailgate is dangerous to use at all, especially when children are around. |

I had the dealer service department check it out but they said they couldn't replicate it. The camera system is not always in a blue screen regardless if I select camera options from the infotainment menu or if when putting the truck in reverse. The dealer is currently having issues with gm providing the right "calibration" to fix this issue. When the camera was working, a strange issue occurred in addition to blue screens. The right side camera turned off and removed visibility from that side of the vehicle through the infotainment screen. I feel this is a huge safety issue since my visibility is severely hindered when reversing in dark or dense conditions. |

| Description | I have had the 2019 sierra 1500 at4 with 6. 2 liter engine in the shop (8) times since purchasing it in late aug 2019 for multiple issues, including the issues relating to the brake software recall. This resulted in me rolling through a stop sign without any brakes. Luckily there was no oncoming traffic. As an engineer, I have no confidence that the issue has been fixed long term by gm. My family will no longer ride in the truck with me. As a result, I have retained an attorney for the purpose of filing suit against gm for selling me an unsafe lemon. Even further concerning is the fact that on (2) occasions the parking brake has engaged while driving down the highway at 55 mph. One time while in 4wd in snow, and the other time while in 2wd on dry pavement. The first time there was a diagnostic code associated with the parking brake engaging randomly. The second time, there was no diagnostic code present. The first issue with braking began 11/14/2019, and the most recent issue occurred on 2/2/2020 even after all recall "fixes" have been applied. *js |

During parking maneuver after coming out of reverse and going into drive, forward camera would come on and then switch to nav screen when I took my foot off the brake. To resolve would go in reverse then back to drive and the front camera would stay on. After vehicle start I go into drive and front camera comes on. Sometimes it does not in the exact similar circumstances. No indication from forward detection sensors. After backing out of a parking spot, going into drive forward camera comes on then the whole screen goes bright blue, after a few seconds forward camera comes back on until I speed up. Other issues not so frequent. Have been to dealership over 9 times for a total of 37 days it was in the shop. Gmc cac useless and do not know the product. Dealership technicians are not familiar with new product or have the computer skill set to fix. |

| Description | After using app to start the vehicle, I sat in the driver seat depressed the brake and pushed the start button. Immediately a warning popped up saying esc needed service, service trailer brake, speed limited to 62mph. Additional lights illuminated including brake, traction control, abs, and cel. Since the dash indicated that the speed was reduced I thought it would be safe to drive, however at the first turn I realized my brakes were nearly gone and I went through the intersection. The brakes appeared to have lost the boost and were extremely hard to depress making it difficult to stop the vehicle. I limped the truck home and notified the dealer. The next day I tried starting the truck and the brakes returned with no dash messages although the cel was still illuminated. There is a recall for a similar issue but it looks like my vin is not apart of it. |

| Description | Every single day I back out of my driveway and when I shift into drive and step on the gas the truck moves forward slightly and the rpms wind up but the truck bogs down like it's got a fuel clog then it shifts into 2nd at a high rpm and jerks forward like someone popped a clutch. This is a major safety issue because once this winter it happened and the real wheels spun and the back end slid out on the ice and the nose of my truck wound up in the oncoming lane of traffic. Dealer and gmc say that a 'hard shift' is a known issue and the truck is 'working as designed' and there is nothing they will do further. I have had it in the shop 3x already. I have read forums speaking of many people having similar issue with 2019 gmc trucks and no fix from gmc. This is not normal, safe and I'm sure no engineer designed this transmission to work this way. |

| Description | Purchased new, dec 24, 2019. Current odometer 645miles. The vehicle was parked for about 15 minutes, when I returned to my truck and turned it on, multiple warning tones began to sound and the dashboard was illuminated with multiple warning lights (abs, traction control, check engine, parking brake) and messages reading: "brake system failure 62mph top speed," 'service trailer brake system,' 'steering assist is reduced drive with care,' 'service esc.' I turned the vehicle off and on multiple times over the course of 20 minutes, exiting the vehicle, locking the doors, unlocking the doors, and starting the process from the beginning. I decided I wouldn't be driving over 62mph as I was only 2 miles from my home, so I decided to back out and drive home with full intentions of calling the dealership in the morning. When I tried to back out I realized that I had almost zero braking power, having to almost stand up on the brake pedal to stop the vehicle without giving it any gas, and turning was difficult (similar to manual steering in a vintage vehicle). I knew driving home would not be safe. I turns the vehicle off and on once more and all the warning messages and lights were no longer there. The check engine light remained on and is still on. I was able to drive home as though nothing happened, but am fearful this will happen while driving down the road, especially while my children are in the car. I have read multiple forums, this is not an isolated incident, with many others experiencing the same exact issue, sometimes while actually driving, in 2019 gmc sierras and chevy silverado's. This is absolutely unacceptable and will result in injuries and deaths if gm does not resolve the issue. |

| Description | I received notice that there are two recalls out for my truck: a brake system recall and a forward camera/collision recall. Had both recalls performed and immediately the forward camera collision alert, lane keep and intellibeam systems didn't work. Delaer informed me there is a problem with the update and I need a new camera. That is on order and pending. More importantly, about 2 days after the updates the truck showed alerts about the brakes, traction control and stabilitrack systems. Upon driving the truck the power/vacuum assist system failed and the brake pedal nearly went to the floor before engaging brakes; I could barely stop. Returned the truck to the dealer and was told its a common issue with the brake recall update (the truck had no such symptoms before the update). If you check out various gm vehicle owner forums you will see scores of silverado and sierra owners with the same two issues post-update: no collision camera and sudden loss of brakes. There is a problem - a very dangerous problem - with these updates. |

| Description | Brand new truck, at4, 15k miles, 5 months old. Was very cold today outside, was in a store and started vehicle remotely. Came outside to a running vehicle, sat in drivers seat and pressed start button. Noticed multiple warning sounds/lights, dash read "brake system failure 62mph top speed", service trailer brake system", steering assist is reduced drive with care" service esc". The abs, check engine, brake and traction control lights were also illuminated. I immediately called my local gmc dealer (who is 5 miles away) and read them all the messages and asked if the vehicle was safe to drive to their location. After a brief hold, the service tech stated the vehicle was safe to drive over. I attempted to drive the vehicle out onto rt6. While still in the parking lot, traveling approx 10-15mph I was barely able to stop the vehicle. It took my full power on the peddle to stop, and approximate 20-30 feet of distance before it stopped fully. I immediately called the service tech back and informed her that the vehicle was not safe to drive with 5% or so break capacity. She provided the gm number for roadside assistance. The truck was towed to their shop a short time ago and I am awaiting their feedback. On a side note, I waited in the truck as I did not want to shut it down, I wanted the service tech to see exactly what was on the screen. After about 30 mins, with me in the drivers seat with the keys, the truck shut itself off. When it restarted the messages were gone, but the check engine light remained. Luckily I took photos and video recorded this issue prior to. The loss of brakes for any issue should be treated with the uttermost care for safety of the general public. This seemly known issue will (if not already) result in injury or death if not corrected quickly. |

Upon restart, everything was gone, no warnings. Approximately 1. 5 miles later I was at highway speeds (70mph) when all the messages returned. I attempted to brake but there was no response, pedal went nearly to the floor. I only survived the incident by shifting into manual, downshifting to engine brake, and standing on the what I'm guessing was 5 or 10 percent brake pedal. Luckily there was an empty lane for me to do this in. |

| Description | Random intermittent vehicle brake failure. I have experienced random brake failure for 45 minutes at a time on my sierra. No codes or warnings are shown when it happens. Occurs while driving, and random. Condition creates an extremely hard peddle with extremely reduced braking power. Safe stopping distance is increased at least 3 fold. Vehicle brakes will start working again if truck is left parked and ignition off after 30 minutes. I brought the truck into the servicing dealer, they drove it 30 miles and a week later, gm instructed me to pick my truck back up after no repairs do to they could not duplicate. I expressed extreme concern about safety, and gm stance is, "no codes no problem". I was instructed by gm to simply bring it back in when my brakes fail again. 2 weeks later, my brakes failed again, creating a dangerous situation. Once again, the truck corrected itself after sitting with the ignition off for 30 minutes. I brought it back to the dealer, and they drove it and "could not duplicate customer concern" once again. Once again I was instructed to bring the truck back in when the brakes fail during their open business hours so that they can see it for themselves. This is an extremely dangerous condition, and this truck should be off the road and concerning to gm, but it is not. Through research, I have found many other people with the same truck year and model with the same problems, and gm is negligent towards our safety and the innocent people on the road. This new "e-boost" braking system needs to be investigated before my family or others are killed or injured by this defective system. Brake failure occurred both times when attempting slowing down for curves and stopped traffic at highway speeds and persisted at all conditions until it reset itself after sitting off for 30 minutes. |

Once I get to work and started backing up at a slight turn bc I was parking next to another vehicle it gave me a blue screen saying 'service rear vision system'. It also does this while stationary. This is a highly unsafe problem to me, because it doesn't allow me to operate the vehicle safely putting me and others at risk. |

| Description | You can constantly feel a bump,clunk & transmission slip when going from reverse to drive. This is dangerous as I was pulling a small boat and it came off the hitch hitting the trucks tailgate and causing damage to it. This will happen seconds after drive is already engaged. After 3rd time I took to dealer the mechanic gave me a gmc memo that states that this is normal for this model truck to do this. Mechanic stated gm has known about this issue for years. Are you kidding me ? Sounds like poor engineering. I was never told this would happen pre purchase or I would of never bought the truck. Have had constant problems with this truck since I bought it. Have had the seat belt pillar cover fall off 3 times dealer says they will change seatbelt, waiting over 2 months and no parts or repair. I have a warning to service brake pad sensor monitor. Took to dealer and they say they can't get parts for it yet because gm is on strike and have been waiting for parts and repair for over 2 months . Have had a steering wheel column warning also. Dealer blames everything on software issue. My diagnostic report each month states truck is in perfect order even though I have had a warning light for over 2 months !!!!! Now there is a recall for the seatbelt pretensioner that it might cause a fire ! What a piece of junk this truck is I tried to support the american economy by buying an american truck and look what I get ! I should of bought a toyota tundra !!!!!!! |

| Description | Putting vehicle in reverse turns the interior display brightness (reverse camera) on as bright as it goes, like a flashbulb going off right in your face. This is especially dangerous at night and leaves temporary blindness which affects the ability to see out into the darkness afterwards. There is no ability to adjust the brightness of the interior display. I can even turn the display off and shifting into reverse turns the camera back on with maximum brightness. |

It took the vehicle approximately 4 to 5 feet to come to a stop after braking. Also the abs, check engine, brake and traction control lights were illuminated. I immediately tried to drive back home and when I drove in to my driveway, I smashed on the brakes and I almost drove through my garage because the vehicle would not stop immediately.

While parking the car at one point the shift was so hard that it felt like a hit, and then the kids confusedly asking "what was that?". Gm is giving us the runaround and unwilling to fix what I have now found out, has been a known problem. They based everything out of what the modules report when the car is hooked up to the computer. Basically, if the modules are ok then the car is reportedly ok. Not the case. |

I slowly started moving through the station and noticed my brakes were almost completely gone. Fortunately I was close to home so I dropped down to first gear and slowly motored home to wait for the tow truck. I had the truck towed to the novato chevy dealership and they could find nothing wrong with the truck. I then began the process of requesting gm to buy this truck back and its definitely not going to be a short process. Im still currently driving this thing with no diagnosis of any brake issue. My wife won't even get into the truck. I absolutely love this truck and wish there was a definitive answer to what happened. Gm corporate said if it happens again to please bring it into the dealership for eval. If it happens again?!!! Im not complaining about the air cooled seats not working properly! I drive a fire engine for a living and my job is to keep others safe. Now I'm having to drive this thing while waiting for gm to step up and buy this back before the brakes go out again. I suppose someone will have to die before gm acknowledges there's an issue here. |

Got back into the truck, started it and the check engine light came on, the brake system failure, the abs light, traction control etc. Called the dealer and was told to bring it back. (mind you, I've only actually owned the 63k truck for an hour) I bring the truck back, they take it in for about 20 mins and then the mechanic takes the car for a test drive. He's gonna about 15 minutes or so, comes back and says the truck is good. They fixed a recall recently but never "reset the computer" he says "you're good to go" I drive the 30 minutes home, pull up to the house, turn the truck off. Go inside to get my little ones because they want to go for a ride in daddy's new truck.. We go outside, I start the truck, and it's the same thing these are the codes that came up. It has been back to the dealer 3 times and they havem't found any issue. This is dangerous and something needs to be done.

| Description | On 5/28/19 I filled my 2019 gmc sierra denali at the local gas station. As usual I turned the vehicle off. After fueling, I started the vehicle and began pulling out of gas station. Upon exiting I lost all braking power and the pedal went to the floor. I was going approx. 5 mph. I pulled over and had to step on the brake pedal until it was on the floor with extreme force. The check engine light also appeared on the dashboard. At approx. 4:41pm I recieved an onstar email with an antilock brake problem. Email suggested I take the vehicle for service within 7 days. I had gmc roadside tow the truck from my home to the nearest dealer(staten island buick gmc) I leased the vehicle from coleman buick gmc and when I contacted them I was told they couldn't help and the dealer the truck was towed to is still gm. I also contacted gm customer service. Received a case # and waiting to be contacted. As per coleman the vehicle has recalls for a trailer brake module and park assist. As per si buick gmc they could not find any computer codes. The hydraulic test showed no issues. They claim to have upgraded the computer and the truck was safe to drive as of 5/30. They want to test drive again on 5/31 and I assume I'll be asked to pick up my truck. I find this to be unacceptable and a major safety issue. Thankfully I was going 5mph when I lost full braking. I was told if the issue happens again to bring the truck back in for diagnostics and repair as needed. This safety issue can potentially cause physical injury and or prove to be fatal. Depending on technology to determine braking capacity is absurd. 2019 gmc sierra also have electrical problems duly noted by customers. Forums also mark the same braking problems have occurred with other owners in different states. A recall should be issued for the safety of drivers, passengers and pedestrians! Lives are at risk and a recall is needed! |

| Description | On april 2, 2019 I parked brefily for about 30 minutes. Upon re-entering my 2019 gmc sierra truck with approximately 4500 miles and starting the engine I immediately received multiple warning messages on my dash panel. They were "service esc" "service trailer brake", "brake system failure" "steering assist reduced" and to drive no faster than 62 mph. Previously prior to parking I had never had any problems whatsoever. I was in a location where I needed to go so I attempted to drive but found quickly that the brake pedel went all the way to the floor with very limited or basically no braking. The steering became very difficult with no apparent power assist. I drove it approximately two miles and got to a location where I could park. I turned the engine off and back on and the problem did not go away. I turned it off again and waited a couple of minutes and then heard an automated couple of clunk sounds from the front.. I started it up and everything was okay except the check engine light was on and stayed on the rest of evening. The next morning the check engine light was still on however about twenty minutes later I noticed it was off and everything has been fine since. I had planned to take it to the gmc dealer however with no problem showing now and from past experience with the dealerships I decided there was no need to schedule an appointment until the symptoms come back. I found on the internet later that there are numerous instances where this has happened to many other 2019 gmc sierra owners. I feel that this is a extremely serious problem that needs immediate attention especially with the near total braking system failure! |

| Description | I am a heavy highway construction inspector for wvdoh and while working on I 81 sb in martinsburg, wv this morning around 2:00 am while performing my duties I attempted to pull out of my lane closure into traffic when my truck literally got stuck halfway out into live traffic. It was as if I was stomping on the brakes instead of giving it gas. Fortunately I reacted swiftly and put the truck in reverse to back into my lane closure preventing a collision with a tractor trailer traveling at speeds in excess of 55 mph. I was literally shaking when I realized how close of a call it actually was and that not only could I or the truck driver have been killed, but so could the workers on my job have been injured and/or killed. I had to have my truck towed back to my field office. For some reason the truck started driving properly again. There is definitely something wrong and it is extremely fortunate that no injuries occurred on my project. I did notice a post on this website explaining the very thing that happened to me this morning. This issue must be addressed immediately before people are killed.

| Description | While driving down road, sudden message of "no oil pressure, turn off engine immediately". Was able to pull over with no power (luckily it was safe to do so at the time). Left a large puddle of oil underneath the front of the vehicle. Also, left large cloud of smoke from oil splashing on hot components underneath vehicle (exhaust, etc...) behind me. Vehicle was undriveable and had to be towed. Large oil leak was the result of a burst oil cooler line. Dealer did not show me the failed part. Unable to confirm nature of "burst". |

| Description | While driving my truck approximately 45 mph on a street, I heard the vehicle notification alarm sound, I looked down at the dash and had several warning lights illuminated:I had four messages: service esc service trailer brake brake system failure - 62 mph top speed steering assist reduced drive with care lights on dash that were illuminated abs check engine brake traction control before I could read each warning light, a red stop light was approaching. I was at that time I pressed on the brakes and realized that my brakes were extremely spongey. I figured I only had about 10% braking power. With my two year old in the back seat, I pushed as hard as I could to stop my truck. Luckily, by the grace of god, I was able to stop my truck without rear ending the car in front of me. My truck was then towed to the dealership. I bought the truck 5 days prior. My truck has approximately 161 miles on it. The dealer told me the next day I needed a new master cylinder and hydro boost. Probably the absolute worse component to fail on the driver while the vehicle is in motion. |

| Description | When I am driving my truck, I will get notifications saying that there is a trailer disconnection issue when I don't even have a trailer connected. It also flashes an alert saying that the lane departure system and pedestrian sensor are being effected. As this is going on, the infotainment screen flashes on and off as well which is very distracting. They have continued to come on in cold weather after I have taken it to the dealership to be looked at. I don't know if this is a hardware or software problem but it needs to be addressed because it becomes both a large nuisance and safety hazards when you have errors messages and lights flashing while you're driving. |

| Description | When the temperature drops below about 20 degrees (fahrenheit) the center instrument cluster starts displaying emergency codes that require constant clearing, only to have the error codes reappear. The same thing happens on the infotainment head unit in the center stack -- it flashes, resets, cuts the sound in and out and displays trailering checklists. All of this is immensely distracting to the driver and creates a safety hazard. I've had it serviced and have been told gm engineers are aware of the issue (its common on 2019 sierra and silverado 1500 trucks) but have been unable to find a solution. I have video of both types of errors. |

| Description | Vehicle screens including both the driver information area and the infotainment screen began flashing alerts/warning about disabled cross traffic alert, lane keeping assistance, and trailer connection/disconnection warnings. Alerts happened ever 2-4 seconds with screen flashes each time. Very distracting in the dark which makes it difficult to pay attention to the road. Almost rear ended another vehicle due to this issues. |

| Description | Have about 6000 miles on my 2019 gmc seirra denali 5. 3 . I've been experiencing a very troubling issue been to the dealership once already and had a hard time convincing them that something was wrong with the truck . Every time I drive for long periods of time or idle for 10+ mins when I shift from park to drive I cannot go faster than 5 mph without the rear brakes locking up. I do not know if this is some kind of limp mode or what . |
