Problems with the Air Bags
The most important safety system in a vehicle is the air bags. However, the Tahoe is struggling to keep people safe with this system.
Here’s an NHTSA complaint. “I have taken my Chevy Tahoe to the service department numerous times – as my truck has had a stubborn service safety restraint system warning error code that continues to come on and off. I have taken it to have all recalls serviced as per recall request. The service safety restraint system warning code has not been corrected after more than 5-6 visits if not more as not all visits have been logged properly. I have had this truck for less than 12 months and have experienced too many conflicting issues. I do NOT feel safe driving my Tahoe with the SRS light on. There’s obviously a malfunction that you all have not been able to figure out. This is extremely dangerous!! What if I were to get involved in an accident or collision and my airbags do not deploy? I may have a problem with the airbags themselves, a loose wire, a faulty seat belt buckle, or a problem with the engine control unit which is causing the airbag warning to come on. There is obviously a major problem. I am putting my children and family at risk. I have not received an email or phone call from anyone at Autonation Chevrolet. The service safety restraint system warning code has come on and off 7x since I was last at the dealership (9/10/21) and I have pictures to support.”
NHTSA Campaign Number 21V421000 states that nearly 300,000 vehicles have an air bag malfunctioning indicator light that might fail to notify drivers when there is a problem because of a failing communications gateway module that needs to be replaced. Without this warning, occupants are at a higher risk of injury during an accident, so where is this “driving confidence” coming from? Apparently, GM wants customers to imagine this protection that isn’t available.
Problems with the Electrical System
In general, a defective electrical system is going to cause communication problems while driving the vehicle. That’s exactly what is seen in the Chevy Tahoe.
One Edmunds customer says, “I bought a 2021 Tahoe in November and dropped it off today (for the 5th time) for electrical work. Problems with infotainment/radio/dash, etc. upon first visit (two days after purchase) the deal said there was no issue. Second time they said a radio was needed. Third visit replaced the radio. Fourth time they replaced the amplifier. Fifth visit brake light and radio will not turn off with the car. This is my first (and last) Chevy purchase. With the cost of this vehicle there should be no issues. This should not be in the shop and unrepairable. Experts from GMC should not have to be called to diagnose problems the 5th time. How many chances does one need? Car goes in with one problem, comes out with two. Just so disappointed with this purchase and experience I highly suggest you ask/research before you buy. It’s beauty isn’t worth the inconvenience and time.”
Chevy isn’t ashamed of all the electrical system problems. In fact, there are more than 100 communications happening within the company. Service Bulletin #PIT5774C discusses how there can be multiple warnings about the sunroof, service safety restraints and other electrical problems. Engineering is working on creating fixes, but the problems seem to be overwhelming the technicians, leaving them scratching their heads.
Problems with the Engine
A well-built motor can make the drive much more enjoyable, but why would anyone think that this vehicle would have a reliable engine?
Another Edmunds review states, “Purchased 2021 Chevy Tahoe Z71 in November. In January there was a popping sound, then knocking sound, then all my service lights came on, then it started rumbling & shaking. Chevy told me to stop driving & tow it in. It was a lift valve that blew & damaged something else. Everything repaired. Well here we are in April with THE EXACT SAME ISSUE and there were no loaners. Chevy is giving me $35 a day toward a rental, but I still have to pay $11 for a full size car… I’d be paying more if I wanted to rent an SUV. My first and last Chevy. I knew I should have kept my X5!”
On the internet, it’s simple to find countless complaints about defective lifters. In fact, the pages and pages of proof are overwhelming. Yet, this isn’t the only engine problem. Service Bulletin #PIP5794B also discusses a vehicle shudder that is caused by the camshaft actuator system, even though it feels like a transmission problem. At this point, it might be best to scrap the entire engine and start over. It’s the only way to ensure the problems are resolved.
Problems with the Fuel System
The fuel system works in conjunction with the engine to ensure a smooth ride. However, GM can’t get this system built correctly either.
This Edmunds review states, “As many have stated on here about the sputtering, shaking and lights going off like crazy, today it happened to me. Third time the car has been in the shop and have had it for about 7 months.”
NHTSA Campaign Number 21V739000 talks about a power control module failure. This defect can cause the fuel pump to fail and cause the SUV to stall. If this happens, an accident can occur. Additionally, NHTSA Campaign Number 21V064000 states that affected models have an adhesive missing between two layers of the fuel tank that can lead to a leak and possible car fire. The only question now is – how many customers are actually wishing for their SUV to burn up in flames at this point? Probably a lot.
Problems with the Vehicle Structure
Why would anyone believe that the 2021 Chevy Tahoe was built the way it should be? After all, there’s not a system on this SUV that seems to operate as it should.
This Edmunds review proves the structure is sub-par. “I have had it in for service now 3 times. There have been several recalls but the real issue is the WATER LEAK. This is the 2nd time I have had it in for the WATER LEAK and they cannot seem to resolve the issue. The last time I had it in for service for the leak, the dealership had it for over a week. The dealership has it now and has had it yet another week with no date in sight to get it back. I cannot believe I paid over $62K for a vehicle and I am having all of these issues. On top of that, I ordered floor mats from GMC/CHEVY and they do NOT fit. I am very disappointed and at this point getting PISSED! I’ve waited my whole life to have a vehicle this nice and it’s JUNK!”

There’s no reason to take the customers’ words on the structure issues. GM itself has issued five recalls related to problems with the seats and seat belts. These simple structures weren’t even produced correctly. What exactly is going on at the GM manufacturing plant? It doesn’t seem that these engineers could put together a LEGO car, let alone an SUV that is meant to protect families.
Problems with Steering
Keeping the Chevy Tahoe on the road seems to be creating its own set of problems. Trying to control this beast is causing accidents.
Here’s an example from the Edmunds website. “Lane changing device is supposed to allow no hands driving. My new 2021 Chevy Tahoe Lane Changing Device overcorrects and forces the vehicle to run off of the road to the right or runs to the left onto oncoming traffic. No matter what GMC advertises do not take your hands off of the steering wheel. My new Tahoe already has six (6) recalls and each time the dealerships advised that the Lane Changing Device is working correctly.”
For starters, GM has been the defendant in a class action lawsuit for previous models because of “Chevy Shake.” This defect leads the SUV to shake and vibrate, especially while driving at higher speeds. However, there are also other steering issues. NHTSA Campaign Number 21V455000 states that more than 26,000 vehicles have a software issue that causes the power steering assist to fail, which requires more effort from the driver to prevent an accident. Basically, the only way to drive with “confidence” at this point is to have very big muscles capable of maneuvering the large SUV without help. Owners better start spending time at the gym to get prepared.

| Description | I have an on going problem with the emissions system on my 2021 tahoe. The vehicle discharges raw diesel fuel and def from the exhaust tail pipe during cold startup. This discharge is overwhelming and is so strong it can be detected by smell from over fifty feet away. In addition to this issue the fumes enter the inside of the vehicle and at times it is so bad you need to open the windows. I believe this problem is unsafe as it poses a fire risk and a co exposure risk to the vehicle occupants. The vehicle has been in the shop repeatedly for the past eighteen months with various parts replaced. To date none of the repairs have fixed the problem. In february gm issued a statement saying that this is normal operations. |

| Description | Gm decided to use brembo brand brake pads and rotors on the front of the newly redesigned 2021 ppv tahoe. I have 16 of these vehicles in my fleet at the sheriff's office and everyone one of them squeals really loudly when the brakes are applied. I now have one tahoe out of service due to the fact it needs pads and rotors on all four corners. The main concern is there are no rotors available anywhere for these units. |

| Description | Received an over-the-air update that rendered my vehicle unless. My vehicle would no longer start, or power on, or power on in accessory mode. It was stuck in park, the electronic parking brake could not be disengaged, the door locks could not be operated and left unlocked, no lights, no warning lights, the emergency lights did not function, no horn, and most everything else. The only things still working were the radio, the driver's side powered seat would move, and the light came on for the parking brake. The battery was fully charged. I also started receiving messages through my chevrolet app that the vehicle had no air in the tires, no oil in the engine, and many other items that needed servicing. I am not sure what exact components or computers have failed yet. Gm could not find any dealer to render aid and come to my location to reprogram the vehicle. It had to be towed to a dealer. With the electronic parking brake engaged, gm had a hard time trying to find a tow truck that wouldn't just drag the vehicle down my driveway and onto a flatbed. |

| Description | On november 9th, 2022 my wife was returning from the store when our tahoe lost power and the engine shut off. She was able to pull off the highway onto a side street prior to the engine shutting off. I met her at that spot to see what was going on with the vehicle. The car was parked on a slight hill and after checking the oil and other fluids I could not see an issue with the car and the car would still not start. I was able to tow the car to a flat spot and checked the fluids again. After about 45 minutes the car did restart with the check engine light on. We were able to get the vehicle to an auto shop about a 1/4 mile down the road where they were able to hook up their reader and see what the check engine light was for. A code of p129f came up which is the fuel pump module, pictures attached of screen. We then were able to get the car home and it was towed to a chevy dealership the following day. There techs were able to find a recall number of 21v739000 which was issued on 9-23-2021 showed that this happened in certain 2021 tahoe's. While our vin number did not fit into the vin numbers on the recall number I still feel this was the issue. I feel this could be a bigger safety issue with other vehicles on the road that did not fit into that recall could still have the issue. While we were lucky and know one was injured the next people may not be so lucky. Also since our tahoe was not in the range of vin numbers on the recall we are being forced to pay out of pocket 521. 81. Which I will be fighting chevrolet to pay us back. |

| Description | 2022 tahoe was inspected for the announced recall. The manufacturer chevy has no timeline for when the 3rd row seat belts will be repaired but only said we cannot use any of the 3rd row seats till fully repaired. I called chevy and ask them what's the suggestion what's if the passenger is 5 or more. Will the give rental fee or a loaner vehicle. They said no. This is totally unacceptable. Gm is offering nothing to customers that purchased 000+ vehicles from them for the very reason that they have big 3rd rows. How are families of 5 or more supposed to function in the meantime? Nhtsa should exert all available pressure on gm to prioritize on-road vehicles and do it now. |

| Description | The contact owns a 2021 chevrolet tahoe. The contact stated that while driving at an undisclosed speed, the vehicle stalled without warning. The contact stated that the transmission independently moved into park (p) and the gear shifter would not move after several attempts. The vehicle was towed to a dealer who informed the contact that they could not repair the vehicle because they did not have the adequate tool to unlock the transmission. Upon receiving the tool days later, the dealer diagnosed that water had leaked into the fuel tank, which led to the failure. The manufacturer was notified of the failure and advised the contact that they would follow up. The contact was still awaiting a call back from the manufacturer. The vehicle was not repaired. The failure mileage was approximately 27,000. |

| Description | Our tahoe was inspected for the announced recall and failed the test. The dealer/manufacturer has absolutely no timeline for when the 3rd row seat belts will be repaired and said we cannot use any of the 3rd row seats until then. The dealer even said it could be a year before parts are available. This is totally unacceptable. Has gm rerouted new seat belt assemblies from their manufacturing of new vehicles to prioritize repairs of vehicles already on the road vs. Keeping their sales pipeline full? I doubt it. Are dealers prioritizing vehicles on the road over those on their lots that are waiting to be sold. I doubt it. These are the very questions nhtsa should be asking of gm. Gm is offering nothing to customers that purchased ,000+ vehicles from them for the very reason that they have big 3rd rows. How are families of 5 or more supposed to function in the meantime? Nhtsa should exert all available pressure on gm to prioritize on-road vehicles and do it now. |

| Description | My car's service safety restraint system alert is on for the second time. I took it to hanner chevrolet in baird, tx the first time and they told me it was fixed. It stayed off for a few months until the alert lit up again. My car is available for inspection. According to the dealership, while that light is on, they cannot guarantee that my airbags will deploy in the event of a crash. The dealership has confirmed that there is a problem and has seen the same issue with many other 2021 tahoes. My vehicle has only been inspected by the dealership so far. The warning lamp is currently on. Luckily I have not had an accident in my vehicle, but I feel unsafe driving it at this time until the issue is resolved. After speaking with the dealership and researching online, it appears that this is a common issue with the 2021 chevrolet tahoe and creates a significant safety threat. I believe a recall might be required. |

| Description | The dashboard for the vehicle loses all power and does not regain power/connectivity. I've had this problem "fixed" 5 times by the chevy dealership and the issues continues. They've replaced the entire dash, checked electrical components, changed out the electrical bank, and the issues continues. Driving down the road at 65 mph to have your dash go out is not only terrifying but extremely dangerous! I have no idea how fast I'm going, how much gas I have, no situational awareness related to vehicles that are close by... The entire dash goes out. This is a brand new 2021 chevy tahoe... I bought it with 4 miles on it and within a month of the purchase, the vehicle had this problem. |

The contact stated that while driving approximately 65 mph with the adaptive cruise control activated, the vehicle stalled and lost motive power. The contact indicated that after the adaptive cruise control reduced the speed due to a nearby vehicle instead of resuming the intended speed, the vehicle lost motive power in the middle of the busy highway and would not restart. The tow truck was called to the scene and discovered that the transmission could not be shifted into neutral(n). The vehicle had to be dragged onto the flatbed of the tow truck. The vehicle was towed to the local dealer. The cause of the failure was not yet determined. The manufacturer was notified of the failure. The failure mileage was 14,608. |

| Description | First fuel system failure occurred at ~3500 miles. Pulled out of driveway, shifted into drive and vehicle stalled and would not restart. Fuel pump replaced first then fuel module replaced resolving issue. Now at 12,100, vehicle again shut down at a major intersection and would not start. Vehicle has been towed to dealership. The vehicle failure mechanism locks the car in park and leaves all electronics powered on. Fortunately I was able to get the front wheels strait during one sputtering start attempt so it could be dragged straight onto the tow truck. Able to power off radio and ac but no other electronics would shutdown, dash display, resulting in total battery drain. Can only lock drivers door with key so vehicle is outside dealer service center on a weekend unlocked. This the second failure of the same component. This abrupt failure creates a completely unsafe situation leaving you stranded unable to move. This vehicle is an expensive failure and based on a second recurrence, the related electronic component issue has not been resolved. First occurrence chevrolet provided a free year of onstar due to me not feeling safe with this vehicle. Now just after this expired, the same failure has occurred. Buy this vehicle back from me chevrolet at my purchase price. First occurrence took 3 hrs for a tow truck to pick up the car which was fortunately in middle of my street. This current failure was 2. 5 hrs stuck at a stop sign in the middle of a major intersection. Thank god I was not on the interstate. |

| Description | I encountered the same issue which most of the other complaints on here saw where the engine lost power (due to one cylinder misfiring) suddenly and it was due to a faulty lifter in the engine. Fortunately, I was able to limp the vehicle back to my house where it could be towed, but had it been worse it could've stalled in an intersection and I'd be unable to move the vehicle due to how the engine must be running in order to put it in neutral. Gm really needs to recall the engines that are affected by the lifter problem as this issue is showing up on several forums online along with this site. My engine date code falls within their tsb, however they only replaced one bank due to my mileage being over 8,000 miles. That means that I most likely get to look forward to more issues soon with the other bank of lifters as they're of the same faulty design. |

| State | GA |
| Description | The vehicle was manufactured with a push button transmission gear selector. If there is an electrical issue(ie. Dead battery, electrical short, engine failure, etc) you cannot shift transmission gears. If I pull into my garage, notice a burning smell coming from engine area, possibly an electrical short, I cannot put vehicle in neutral to push out of garage in case it does erupt into a fire and not burn down my house. Recently my dead battery caused the tow company to lift the back end and pull it our of garage. General motors did not install an override to put transmission in neutral in an emergency. The transmission will only shift if the engine is running. Imagine driving on a road or stopped at a traffic light and the engine stalls, will not restart, good samaritans offer to push you off the road, but can't shift to neutral. Dealerships have a hydraulic lift they place under rear tires to move vehicle around service area. As a retired law enforcement officer, many times we had to move vehicles out of the way until wrecker serviced arrived. I feel this is definitely something that has to be addressed and corrected before major damage occurs or lives are endangered. |

This is a huge safety issue as my tahoe broke down in the middle of a very busy intersection at night time, and it took 3 hours for a tow truck to show up.

| Description | Experienced a collapsed lifter on my 2021 chevy tahoe at 18,000 miles,also had a bent push rod, all whiling 40 mph. This is my second time having this issue. There is a problematic design with the active fuel management system. The frequency this is occurring is unacceptable. I also had the same issue on another gm truck at 120k miles which costs 6,000 dollars to repair. |

| Description | This model engine stalls/cuts out acceleration because of valve lifter problems. While chevrolet has repaired many of these engines, they are waiting until the check engine light comes on (or flashes) to initiate the warranty repair. It is very possible to be miles from a dealer, requiring a tow, and the dealer not having the repair parts in stock. |

| Description | Gm has been building v8 engines with a known defect that is bending push rods and damaging lifters. These newer engines use a dfm system and that system is compounding this engine defect. Gm has refused to replace all the lifters and is going forward with just fixing engines as they blow up which can happen at any time. The 5. 3 and 6. 2 engines are a ticking time bomb and can leave you without engine power at any given time when a lifter fails or a push rod gets bent. Hopefully the nhtsa will look into this issue and force gm into a recall. |

| Description | The sunroof made a very loud popping noise and exploded while driving on the interstate on november 30th around 12:15pm in about 40-50 degree temperatures. There were no warnings or noises or any indications that something was wrong. The safety of myself and children were put at risk, as the glass came down into the car while driving on the interstate, and presumably the safety of other drivers if some of the glass flew off onto the interstate. A local body shop has taken photos, as have I, and we have filed a claim with our insurance company. Our local gm dealer did not want to cover the cost under warranty, claiming there was no way to prove exactly what happened. The vehicle has been looked at and temporarily fixed by a local body shop, but not thoroughly inspected. The body shop has ordered new glass and will inspect the vehicle next week. |

| Description | I have has this vehicle for just over a year, and in the time I have accumulated 8,600 miles. Suddenly, yesterday after normal I stopped for a red light. The start/stop function came on (normally) and then all of a sudden the vehicle restarted it self, but, it started running rough, and misfiring. When I moved it backfired several time. I had to have the car flat bedded to the dealer, and apparently it has a known issue, with the lifters and the push rods. The dealer stated it will take a while to get the parts. H as 5 others in the shop for the same problem. My comment is, I am lucky this happened at a stop, I think this would be a major issue if this was to happened at 65 mph ? You could end up in an accident while you deal with the issue. |

| Description | While driving on a residential street during daylight hours, on a clear day at approximately 20 miles per hour the right wheel on my car dislodged. Â this caused me to lose control of steering the vehicle and strike a parked car. Â there were people walking about on the sidewalk at the time and other cars traveling. Â when I exited the car I saw that the passenger side was completely on the ground and there were broken pieces and liquid coming from underneath the car. Â the axel was broken with a clean break. Â the car was then towed to the dealership where I was informed it could not stay. Â my insurance company then towed it to their repair shop where upon assessing the damage they could tell that this was not caused by a collision. Â general motors along with our independent investigator examined the parts and vehicle. Leaving me without a vehicle for 4 months. Â our insurance investigator determined this was a defect in manufacturing and gm did not agree. Â general motors will not communicate with us any further on this matter. Â some of the repairs that were made was the left front and cv axel, also the left front aluminum steering knuckle was missing. Â this should be investigated for metallurgical discrepancies by an independent lab. Â while the car was being inspected there was a recall to the power steering that may apply to the vehicle. Â I would like for the nhtsa to investigate this issue. Â the car has been repaired and is in my possession and my insurance company has all of the reports, documents, and parts regarding the investigation. Â I also have pictures immediately following and a witness to the incident. Had a been traveling on a highway at a higher rate of speed this could have been fatal. Â your assistance in this matter would be greatly appreciated. |

| Description | On 10/21/2021 while driving about 65 mph on highway 80 in sacramento my sunroof glass exploded. It was not struck by any object. The weather at the time was rain and about 60 degrees. Traffic was light and nothing near that could have caused this to happen. Fortunately the shade was closed preventing any glass to enter the interior. Its been in at the dealer stevens creek chevrolet in san jose since 10/21/2021 waiting for a replacement glass. This incident could have injured anyone in the vehicle if the shade had not been drawn. So far it appears it is being handled as a warranty issue. |

| Description | Traction control and forward collision warning lights stared to go crazy in august 2021 (3800 miles), five months after buying my tahoe. Sales rep indicated his new 2021 silverado did the same and he was able to get it to reset by turning off and restating his engine. So I did the same and thought my issue may have resolved itself. Yesterday, the warning lights started to go haywire again (6700 miles) this time my vehicle felt as though it was going to stall and was making a clicking noise under the hood. The warning lights continue to flash regardless of how many times I turn on and off the engine. The engine also revs loudly. |

| Description | I purchased a 2021 chevy tahoe from autonation chevrolet 11-3-2020. I have taken my tahoe to the service department numerous times - as my truck has had a stubborn service safety restraint system warning error code that continues to come on and off. I have taken it to have all recalls serviced as per recall request. The service safety restraint system warning code has not been corrected after more than 5-6 visits if not more as not all visits have been logged properly. I have had this truck for less than 12 months and have experienced too many conflicting issues. I do not feel safe driving my tahoe with the srs light on. There's obviously a malfunction that you all have not been able to figure out. This is extremely dangerous!! What if I were to get involved in an accident or collision and my airbags do not deploy? I may have a problem with the airbags themselves, a loose wire, a faulty seat belt buckle, or a problem with the engine control unit which is causing the airbag warning to come on. There is obviously a major problem. I am putting my children and family at risk. I have not received an email or phone call from anyone at autonation chevrolet. The service safety restraint system warning code has come on and off 7x since I was last at the dealership (9/10/21) and I have pictures to support. |

| Description | In late may, 2021, an "over-the-air" software update was forced onto our vehicle by gm. This update was initiated, and resulted in a failure of the over-the-air system. We brought our vehicle in to our dealer, who indicated that the "module" is bad and a part is required to fix it. This part is reportedly "on backorder" with no known eta. This has resulted in various notifications (turn signal indicators, and unknown other notifications on the dash) as well as our center console (music, nav, etc.) to become unresponsive. Since the "module" failure, gm has issued two additional safety recalls. In the paper notices we received for the safety recalls, gm indicates that they had been "prompting owners through the vehicle's radio screen" for a month, via this over-the air system, of which, ours has not been functional since late may 2021. The last of which is a power steering recall, which may result if loss of power steering functionality. Due to our inability to know the recall existed, resulting from the faulty "over-the-air" system, my family took a trip through the mountains only to return home to this recall notice. Gm has been unresponsive in repairing the system used to notify us safety hazards related to the vehicle that we have purchased, beyond noting that they are trying to "get the part as soon as possible". No one has been able to indicate what this "part" actually is, to date. The possibility of this module failure, and our non-functioning module, presents a serious safety hazard to drivers with this technology who are not made aware of recalls and other safety concerns which may result in crashes and serious injury or death. |

We had the 2021 tahoe toed to vaden chevrolet in beaufort, sc, where we purchased the vehicle. The dealer confirmed it was an engine problem. 8 lifters along with other associated parts need to be replace. This is a major engine repair. The vehicle is 8 months old and has approximately 10,000 miles on it. Doing internet search, the failure of engine lifters in tahoes and silverados appears to be a known problem. The service department manager told me that they have already done 10 of these this year. Failure of an engine while driving is a major safety issue. The vehicle is in for repair, now. |

| Description | There is a serious cabin air pressure issue in this vehicle. When driving at any speed with the windows up, there is a booming inside the cabin, as if the passengers are inside of a subwoofer. My theory is that the headliner panel has too much flexibility in it due to the ceiling air vents. When driving, it is likely the headliner is bouncing up and down, creating the booming air pressure. Within 2 weeks of delivery of this new car and daily driving, my passengers and I developed serious ear issues which we attributed to the car. It got to the point where I would immediately have pain and ringing in my ears just driving a very short distance. None of my other cars including suvs cause or have ever caused this issue. It is important to note that with all 4 windows rolled down, the problem does not happen. It's only when the windows are up. I have the ls trim without the sunroof. |

| Description | After turning off a major highway (65 mph) onto a side road after driving for approximately eight hours, the transmission shifted into n... On its own. The engine continued to run but the vehicle would not move. We could not shift into p, r or d. When attempting to shift into p, r or d, an error message appeared on the dashboard that said "conditions not right for shifting." we turned the vehicle off and then back on and the error cleared. The vehicle continued to drive "normally" for another two hours and the end of the journey. Had this happened in the middle of heavy traffic, a deadly accident could have occurred. Mileage on vehicle is 4,900. Date: 13 july 2021 at 1800 hours. Dealer has been notified but has taken no action to date. There were no warning signs or messages prior to the incident. I'm guessing it is a sensor or software problem related to the engine/transmission. There is a paragraph in the owner's manual that states: "under certain conditions, propulsion will be disabled. Try restarting after the ignition has been off for two minutes." it offers no other explanation as to what "under certain conditions" means. |

| Description | We have owned this 2021 chevrolet tahoe for a little less than a year. Since acquiring this vehicle, there have been multiple safety recalls and we have had to get the vehicle serviced 3 times due to electrical issues. Now for the major safety issue, was out of town waiting at a red light in a turning lane. As we were waiting, the tahoe spontaneously turned off. All of the indicator lights on the dashboard were illuminated and my husband tried to restart the car but the engine just kept turning and the car would not start. We put the hazard lights on and wanted to get the vehicle out of the road where there was active traffic. However, the vehicle was unable to be shifted to neutral so we were stuck and also important to note the hazard lights were not working. We towed to the nearest dealership and tow driver had to apply wd40 on the ramp to get the truck off since it wouldn't shift to neutral. At the same time, my husband received an email from onstar "an issue with the engine and transmission system in your 2021 chevrolet tahoe has been detected." now being told by dealership this was caused by a fuel pump module cut off, causing the car to go into "limp mode" so who knows what is true. I do not feel safe driving this car nor having my kids in it. This would be a very different conversation if this happened on a highway. This vehicle should be recalled because someone gets killed. |

| Description | On my way to work a few days ago I noticed a lag while driving and a knocking feeling/sound ever few seconds going highway speeds. No engine light came on to warn or tell of an issue. I thought maybe it was just a section of roadway that makes cars ride rough. Anyway, made it to work and I could hear a whining sound every time I gave vehicle gas and rpms increased. We called our gm dealer and he said it's a known issue of collapsing lifters and to bring it in for repair. Vehicle had around 5900 miles. 20% oil life was left. I checked oil and level was fine. I'm in a loaner now waiting for repair. If it's a known issue, why is it happening. Inferior parts or bad design? A recall needs to happen before someone gets hurt. |

May 24 car ready, pickup and 68 miles later same problem while on i95 in sc. Did not trust engine and drove in right lane. Gm played russian roulette with our safety and that of other people on road. Sudden engine failure can result quickly in accidents with possible casualties at highway speeds. After pulling of i95, called gm road assistance. Towed to dealer. They were of no help. Family member from chs , sc send trailer to bring us all the way home in new smyrna beach fl. While on phone with gm road assistance we idled the engine to keep cell phone charged. Suddenly engine stopped and on restart heavy smoke came from tail pipe. May 25 car delivered to dealer in nsb where we bought car. May 27 they informed us same lifter/rod problem occurred on other side. Look at chevroletforum. Com and you will see 2021 6. 2 engine having these problems within 8000 miles. Have been in contact with gm customer assistance center since may 14. We do no longer trust this engine. Gm already decided to redesign the lifters as they are aware of the problem. No recall has been issued yet. Consider this a serious highway safety issue. Do not consider the car a lemon, but yes the engine sure is. |

On 5/19/21 I was getting on the highway with my wife and 3 young children and began receiving many of the same error messages. The car was brought to the dealership the following day and I found out that this was another major engine issue. They need to order several parts, one of which is on backorder. As of 5/24 it has been out of service for an additional 5 days, bringing the total up to 27 days out of service, and there are currently 4800 miles on the car. |

| Description | I was driving east bound on I-10 in southwest arizona at about midnight at 75 mph with cruise control when both headlights suddenly went out; visibility was suddenly zero. I pulled back on the bright lever and my brights came on giving me vision. I checked the lights knob and the lights were turned off. I turned the lights on and they functioned normally. On analysis later I think when I moved my flexed knee toward the door my knee contacted the lower part of the light knob and turned the lights to the off position. The lights knob is lower and closer to the center compared to other previous tahoes I have owned making it easier for the driver's knee to make contact with the lights knob so the lights can accidently be turned off. I solved the zero visibility in a few seconds. If it would have taken me 5 or 10 or more seconds I could have been killed. Drivers of this 2021 tahoe should be warned that their knee could turn their lights off and that if that does happen pulling the bright lever or turning the light knob back on can correct the problem. In the future this light knob should be changed; putting it higher and more toward the door would be better or anywhere it can't be accidently turned to the off position. This is extremely dangerous and people could be killed! Please warn the drivers of the 2021 tahoe and any other vehicles with similar light switch designs and make corrections with the light knob in the 2021 tahoe and vehicles with similar designed light switches. |

This occurred on a very busy highway, where my vehicle was surrounded by many other vehicles driving at high rates of speed. It was a very frightening situation and I immediately exited the highway and stopped at the nearest safe location, which was a wendy's restaurant. At the time that this serious safety defect occurred, my brand new 2021 chevrolet tahoe rst, which I had owned for less than 6 months, had only 5334 miles on it. I contacted onstar and was told there were no issues detected and that I should "take it easy" and continue driving. The engine continued shaking and sputtering for about an hour and then stopped. We went to atlanta to meet with family and parked the car. The next morning when I went to start the car, it began shaking and sputtering again like the engine was going to blow and the electric panel on the car displayed a number of errors. I contacted onstar and was informed there was engine trouble and I should take the car to the nearest dealer. I still have not gotten my car back. I have initiated a lemon claim with gm but they have said there's a backlog and have no eta on when this issue is to be resolved. Meanwhile, my family is out of a vehicle and I am still paying a car note for an ,000 brand new car that I do not have access to and that is too dangerous to drive. Something needs to be done about this as I've seen other reports of similar issues on the internet. Please help. |

| Description | Took delivery of vehicle on friday, january 29th, 2021. While driving home from plymouth, ma to concord, nh, I was using the adaptive cruise control. I was traveling between 65mph and 70mph. Roads were completely dry, there were no other cars near me, and there were no obstacles in front of me. I was traveling in the middle lane of a three lane highway. Out of nowhere, the brakes were forcefully applied by the computer which nearly brought the vehicle to a stop in the middle of the interstate. After reaching my destination I noticed that the camera in the driver side mirror was not functioning. Contacted dealer the following day and returned back to dealership to have the vehicle repaired (nearly 2 hour drive). Dealer stated that the issue with the camera and the issue with the automatic braking were related. Picked vehicle up on february 8th after vehicle was supposedly fixed. Arrived home and discovered same issue with camera not functioning. Took to dealer in concord, nh to try to repair again on 2/15/21 and picked up on same day. Dealer found loose pin in connector. Dealer stated that the camera had been replaced in october 2020 before I even owned the vehicle, so someone knew this was an issue. Took vehicle on a drive on 2/17/21. Alert on dash now says 'service driver assist system.' I do not feel safe driving this vehicle and my wife does not feel comfortable driving it or letting our twin 3 year old boys ride in it. I have a case open with general motors on this but they have declined to help with exchanging the vehicle. I'm thankful that nobody was riding with me and that no cars were around and that it was not slick when the braking incident occurred because it certainly would have caused an accident.

| Description | The service safety restrain system warning keeps coming on along with the airbag readiness warning. We have taken it into the dealership twice in the first month of owning this vehicle and we were told there is no current fix. However the manual states to have the vehicle serviced immediately to avoid injury due to the airbags might not be working properly. This warning goes off every 2-3 minutes when driving after we reset the alert. This started happening the minute we drove it off of the lot. |

Bought a brand new 2021 Z71 and it’s been in the shop several times for repairs. I was so excited to get this truck because I had driven my 2006 Tahoe Z71 for 14 years and it was the best truck EVER. I loved the new body style of the 2021 so waited until they were available and bought one. I have been extremely disappointed to say the least. The truck wasn’t even 3 months old and we had a MAJOR leak in several different area of the truck. Water started pouring out of the top of my seat belt holder on the driver’s side, then it poured out onto the floorboard on the driver’s side, and then came pouring out from where the OnStar control button/moonroof buttons are at the top middle near the windshield. That particular area cause water to pouring directly into my car changing area in the console. Not even a month later, the entire electrical panel went crazy. I got in my truck one day, drove maybe 100 yards and all the lights lit up on my dashboard and told me that it was too dangerous for me to drive my truck so that was the electrical panel issue. Not long after that, a very loud noise starting coming from my moonroof. It ended up being that water was leaking into my truck. They had it for almost 3 weeks and thought they had fixed it. Nope, we’re fixing to put it back in the shop for the THIRD time to fix this problem! Also, already had to replace the tires with less than 30k miles on my truck. This is completely ridiculous! I was able to get them to pay for an extended warranty after the 2nd time of it leaking. Now, I’m passed that point and want them to take this lemon back and give me a new truck! 😡😡😡
