GM boasts that the 2018 Chevrolet Colorado offers the complete balance between “work and play.” Surprisingly, owners tell a completely different story. In fact, many people have spent weeks waiting for repairs to be performed on their trucks as equipment continues to fail. Some of the main concerns are related to noisy powertrains, defective diesel engine sensors and faulty infotainment centers. All of these issues combined create more work and less play.

Problems with the Transmission
Drivers want a smooth, comfortable ride as they head down the road. The transmission is responsible for providing a well-balanced shifting experience that someone can barely notice occurring. That isn’t what Colorado owners have come to find about their mid-size truck. The actual experience brings vibration and plenty of noise.
One driver posted this on Edmunds, “I purchased 2018 Colorado new at champion Chevrolet Johnson City TN and at 2,000 miles transmission developed a vibration in transmission most of the time.I returned to the dealership for repairs and tech. said he could not find anything wrong and since the check engine light was not on there was nothing wrong with the transmission. I left and it vibrated all the way home. At 5,000 miles it appears to be getting worse, I have an appt. at another dealership this time. Tarr Chevrolet in Jefferson City,TN. Changed the fluid in the transmission and this resolved the problem. I also found a service tech,notice concerning this problem which has been ongoing for a few years but apparently, Champion Chevrolet in Johnson City has no knowledge of this problem or does not care about their customers.”
Interestingly, the dealerships, in this case, don’t know what the problem is considering GM has addressed it directly. In Service Bulletin #PIE0405A, the automaker acknowledges that customers experience a shake or shudder while driving with the 8L90 or 8L45 transmission.
Not only do they recognize the torque converter shudder, but they also released Service Bulletin #PIP3366C which refers to a grinding or ratcheting noise when shifting into Park. All in all, it seems there are plenty of powertrain noises to go around with the Colorado. For someone that doesn’t expect them, these sounds could become quite alarming, or you could just crank up the radio and forget about it.
Here are some actual complaints logged with the NHTSA about the 2018 Chevrolet Colorado Transmission Problems:
TL* THE CONTACT OWNS A 2018 CHEVROLET COLORADO. WHILE APPROACHING A STOP, THE VEHICLE DOWNSHIFTED WITHOUT WARNING. THE FAILURE OCCURRED INTERMITTENTLY. BOB HOOK CHEVROLET (4144 BARDSTOWN RD, LOUISVILLE, KY 40218, (844) 212-4818) DIAGNOSED AND REPAIRED THE TORQUE CONVERTER AND CHANGED THE FLUID, BUT THE FAILURE PERSISTED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 15,000.
WHEN THE TRUCK IS PUT IN AUTO 4WD MODE WHILE PARKED, INSTEAD OF THE 4WD ENGAGING AS NECESSARY, IT ENGAGES IMMEDIATELY UPON MOTION. THIS MAKES THE AUTO 4WD OPTION OBSOLETE.THIS WAS FIRST NOTICED WHEN I USED 4WD AUTO MODE FOR THE FIRST TIME IN OCTOBER 2018. I’VE NOTIFIED THE DEALER BUT THEY DON’T SEEM TO THINK ANYTHING IS WRONG OR NOT FUNCTIONING PROPERLY.
2018 CHEVROLET COLORADO SHAKING AND SHUTTERING VIOLENTLY WHILE DRVING. EXTREMELY DANGEROUS. CHEVROLET IS NOT LISTENING TO ALL THE COMPLAINTS. ARE THEY WAITING ON A DANGEROUS DEADLY ACCIDENT BEFORE THEY ACKNOWLEDGE AND RECALL THE VEHICLE AND REPAIR THIS DANGEROUS SITUATION!
Problems with the Engine
There are several engine options available on the 2018 Chevrolet Colorado. While it seems to be only minor issues with them all, the most noticeable giving trouble is the diesel option. Most owners choose this lineup for the towing and capability, but they actually receive more than they bargained for.
One Edmunds reviewer said, “Owned the truck less than 24 hours and the DEF sensors tripped. 18 month of ownership, 18 trips to the dealer. When the system is operating properly, this is a great riding /towing package. When the sensors ‘trip,’ you have 100 miles until the power is reduced. Dealer has replaced, re-programmed, nothing works long term.”
GM Service Bulletin #PIP5370C addresses this concern and some others as well. The customer could notice an exhaust fluid quality poor message on the Driver Information Center or see the diesel exhaust fluid warning lamp as well. The automaker’s fix for this situation is to inspect the “diesel exhaust fluid (DEF) system and its components.” That’s it. There is no root cause or long-term remedy, so it looks like it’s something drivers have to live with.
When you purchase a diesel truck, you expect a workhorse. Instead, Colorado owners seem to have acquired a lame horse instead.
Here are some actual complaints logged with the NHTSA about the 2018 Chevrolet Colorado Engine Problems:
I HAVE A 2018 CHEVROLET COLORADO LT 4WD CREW CAB. MULTIPLE TIMES ON A COLD START THE ENGINE IS MISFIRING. THE CHECK ENGINE LIKE COMES ON, THE VSA, AND T/C LIGHTS ALL COME ON AND A NOTIFICATION ON THE DASH SAYING STABILITRAK IS DISABLED. THE VEHICLE SHAKES TERRIBLY. THE CHECK ENGINE LIGHT WILL FLASH AND THEN GO SOLID. I AM AN AUTOMOTIVE TECHNICIAN. I KNOW THAT A MISFIRE SHOULD SET A HARD DTC. WHEN THE VEHICLE IS TURNED OFF AND STARTED SEVERAL HOURS LATER THERE IS NO CHECK ENGINE LIGHT OR ANY OTHER LIGHT ON. THE DEALERSHIP IN MARYSVILLE, OH HAD MY TRUCK FOR 3 DAYS AND TOLD ME THEY CLEANED A BUNCH OF TERMINALS AT SEVERAL CONNECTORS. WHATEVER THAT IS SUPPOSED TO DO. THEY SAID THEY STARTED THE VEHICLE SEVERAL TIMES AFTER AND EVERYTHING WAS GOOD. THE NEXT DAY AFTER I PICKED THE TRUCK UP, IT DID THE SAME EXACT THING! EXTREMELY FRUSTRATING! I KNOW A CONTINUOUS MISFIRE LET’S UNBURNED FUEL INTO THE CATALYTIC CONVERTER WHICH LEADS TO PREMATURE BREAKDOWN OF THE CATALYST. SO MY QUESTION IS WHAT IS BEING DONE ABOUT THESE ISSUES?
WHILE DRIVING HOME, YELLOW CHECK ENGINE LIGHT CAME ON & I NOTICED REDUCTION OF OIL PRESSURE. PARKED IN DRIVEWAY, SHUT OFF ENGINE, WENT INSIDE. UPON RETURNING, NOTICED SIGNIFICANT AMOUNT OF OIL ON DRIVEWAY. DIPSTICK SHOWED NO OIL. TOWED TO DEALERSHIP. THEY VERIFIED LEAKING CAME FROM DEFECTIVE OIL COOLER LINE HOSE. WAITED SEVERAL DAYS FOR REPLACEMENT PART. THIS IS A NEW 2018 COLORADO Z71 WITH ONLY 5K MILES ON ENGINE. AND, THIS IS A SYSTEMIC PROBLEM THAT GM HAS KNOWN ABOUT SINCE ’15 AND IMPACTS BOTH COLORADO AND CANYON MODELS (THERE ARE SEVERAL COMPLAINTS ON WEB). THIS IS A DANGEROUS PROBLEM AND SHOULD BE INVESTIGATED BEFORE SOMEONE GETS HURT. IT WAS NOT A SLOW LEAK. OBVIOUSLY, IT IS MANUFACTURING PROBLEM. ADDITIONAL INFORMATION (INVOICE AND PICTURES) AVAILABLE UPON REQUEST.
Problems with the Infotainment System
While some electrical systems of the truck are for valuable system operations, other systems are for creature comforts and amenities. It doesn’t matter which one of these is faulty; it becomes a significant inconvenience to the owner.
One driver on Edmunds has several complaints about comfort and technologies. They said, “Drove one for five days and after those five days, I could hardly walk. The seats are the most uncomfortable I’ve ever been in. The infotainment system continually dropped the connections and wasn’t at all dependable.”
Interestingly, they have several Service Bulletins regarding an intermittent blank or flickering Driver Information Center. Both Service Bulletin #18-NA-266 and PIC6333B tell the technicians to check the software for updates. Other than that, there are no known fixes available at this time.
While it’s a good thing that these electrical shortages aren’t related to necessary equipment, no one wants to deal with this inconvenience either. With no fix in sight, it can quickly become annoying and distracting to the driver, which could potentially lead to an accident. You could make the best of the situation and pretend it is a strobe light jamming to your favorite tunes, but we don’t recommend turning your truck into a disco just yet.
Here are some actual complaints logged with the NHTSA about the 2018 Chevrolet Colorado Electrical Problems.
TL* THE CONTACT OWNS A 2018 CHEVROLET COLORADO. THE CONTACT STATED THAT THE DIMMER SWITCH DID NOT ACTIVATE WHEN THE VEHICLE WAS IN MOTION. THE CONTACT STATED THAT THE INTERIOR LIGHTING WAS BRIGHT AND IMPAIRED HIS VISION WHILE DRIVING AT NIGHT. IN THE DAYTIME, THE LIGHTS ON THE INSTRUMENT PANEL WERE TOO DIM AND PREVENTED THE CONTACT FROM SEEING THE INSTRUMENT PANEL DISPLAY. THE VEHICLE WAS TAKEN TO BRUCE CHEVROLET (1084 SW OAK ST, HILLSBORO, OR 97123, (503) 388-4240) WHERE IT WAS DIAGNOSED THAT THE DIMMER LIGHTS FAILED DUE TO A SHORT IN THE COMPUTER SYSTEM. THE MANUFACTURER WAS NOTIFIED AND DID NOT ASSIST. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 50.
THE DISPLAY FOR THE BACKUP CAMERA IS ON AT FULL BRIGHTNESS. THERE IS A CONTROL KNOB TO DIM THE INTERIOR LIGHTING AND DISPLAY, BUT WHEN THE VEHICLE IS PUT INTO REVERSE, THE DISPLAY GOES TO FULL BRIGHTNESS AND CANNOT BE CONTROLLED BY THE BRIGHTNESS CONTROL KNOB. AT NIGHT, THE PASSENGER SIDE MIRROR IS NOT USEABLE SINCE THE BACKUP DISPLAY IS SO BRIGHT. THIS ALMOST RESULTED IN ACCIDENTS WHEN BACKING UP INTO A PARKING SPOT.

| Description | We reported issues with our thermostat to our dealer back in september of 2022. The vehicle would not defrost or heat. We were then told the thermostat required replacements but there was no part in existence and they would notify us when it became available. After following up numerous times with no actionable timeline from the dealer we consulted with a secondary mechanic who confirmed the issue was related to a thermostat sensor malfunction and would require a replacement thermostat. Again we were told that the item was not available from gm and we would be contacted when more information was available. A spac case was created by our dealer in october of 2022, notifying the system of the urgent need and our dealer has followed up numerous times that gm has not provided any timeline for replacement. I have also filed a separate claim in january of 2023 to gm customer service notifying them of the ongoing issue and escalating to upper management. I have not heard back on mitigation or rectification plan for our issue. This ongoing issue is a major safety concern that has rendered my vehicle unfit for operation. I am unsure why gm is not making this major safety concern a priority because we are now in the middle of a chicago winter we're temperatures are regularly below freezing. I cannot defrost my windows or maintain a safe cabin temperature. This is unsafe for me to operate let alone use the vehicle to transport my child because of the immediate danger it would place her and I in. I am now paying for a vehicle that has sat inoperable in my driveway for 4+ months with no end in site and opening is up to additional damages because it has had to remain inoperable for an extended period of time. |

| Description | When traveling at any speed usually between 1200-2200 rpm there is a rumble strip/ vibration feeling coming from the vehicle most notably around 35-45 mph but happens at all speeds. I took it to my local mechanic and it was not a suspension, tire or drive shaft issue. I was informed it seems to be coming from the transmission. Upon looking on other forums about this issue it seems to be a common problem with the 8 speed transmissions on the colorado's. I still have been unable to fix this issue. No indicator lights are on, engine runs fine its only when traveling when the engine is between 1200-2200 rpm |

| Description | My 2018 chevrolet colorado is having transmission issues. It started at 90,000 miles and is now getting worse. The transmission stutters at various speeds and is very pronounced while going up an incline. I have taken it in several times to a chevy dealership only to be told nothing is wrong and no warning lights are on. Finally and just this week I have a dealership that is saying a code came up saying the transmission fluid needs to be change since they receive a service technical bulletin saying the wrong transmission fluid was original installed and needs to be replaced. The repairs are at my costs and it just doesn't seem right. Is there anything I can do? |

| Description | The wiring harness was touching the air condenser line. The line gets hot when air conditioning is used. It melted causing my truck to throw a lot of random alarms. It also would turn my cruise off and make it down shift all of a sudden startling me. Melted wires are also a fire hazard. There is a bulletin for wire harness chafing that gmc knows about this issue. If it had melted something major and shut my truck down while driving down the interstate it would put me and anybody around me in danger. It was wired back together but is still not fixed. Might need a new wiring harness. |

| Description | Occasionally the ignition key cannot be turned to the off position and cannot be removed. After shifting to park, the key can be turned to position 1 (acc) but will not turn all the way to position 0 (off) and therefore the key cannot be removed from the steering column. So far I have been able to temporarily resolve the problem by re-starting and stopping the engine several times. The number of times the cycle must be repeated is not consistent. On one occasion, the driver was not able to remove the key so the key was left in position 1 for several hours. This resulted in a drained battery and the truck would not start. We needed a mechanic to come by and jump start the truck. |

| Description | The multimatic dssv damper in the left rear lost its fluid through a leak. Various forums indicate there is a design flaw with the dssv for the zr2. A blown shock renders the vehicle unbalanced, and marginally safe in unexpected rough terrain or when pulling a trailer. These dampers or shocks have shafts that are too thin and poorly designed seals, causing them to leak. |

Happens frequently and so far, starting it, putting it into drive or reverse and move a bit, then back into park will work. At some that might not work and I'd have to leave the key in the ignition and leave the truck unattended. I could still lock it, but if some kids see it or break into it, they could drive it away.

| Description | This started about 3 months after I got the truck and has been doing it since. On three separate occasions, truck engine shut off after stopping then turning right on city and neighborhood streets. First time I pulled out on a road where the speed limit is 55 so I was lucky no one was behind me when the engine cut out. On the fourth occasion, truck shut off after backing up from parking spot and pushing on gas to go forward. No check engine lights, no noises or vibrations to tell me truck is going to shut off. I have to look at dash to see if it has gone black. Radio still works, and I'm able to steer off to side off the road because it's still in motion from after the turn. I can put gear in park position, turn key to off, then start the truck like normal. Have gone to mechanic and dealership and they can't get it to duplicate. Chevrolet has been notified but has said they cannot help if dealership can't find the problem. Steering wheel also starting to get stuck in turn position when turning right. Right after the turn it feels like it catches in something and I have to force the wheel back to center. Starting to happen almost daily, but not for dealership. I feel driving the truck is a safety hazard for not only me but others on the road. |

| Description | 2018 chevy colorado zr2, 21000 miles. Engine shut down while driving in motion on road. Restarted twice and shutdown again twice. Check end engine light came on and traction control said it was disabled. Started third time and put in drive. Wouldn't put power from engine to drive train. 4th start, put in drive and limped back home. Was towed to closest dealer and they cleared error codes with diagnosing. I scanned codes before being towed and error codes were u0700 and u0100. After 3 days of no comms from 1st dealer had 2nd dealer pick up via tow truck. They said 1st dealer cleared codes and could not duplicate. Picked up truck and ran fine for a week, then had same issue on busy road. Had to restart, engine light came on and limped back home. Scanned codes and received same u0700, u0100. Dealer is having tow truck pick up truck to diagnose and repair. This is a serious issue causing truck to shut off while driving and not knowing if it will restart and have power to drivetrain. |

| Description | Duel drink (coffee) cup holders next to shifter leak from any drip or spill. It is not designed to contain any small or insignificant spill or drip. Any liquid leaks down directly upon sensitive exposed electrical dip switches needed to shift the truck. This includes the rubber reservoir (does not hold water and directs liquids through knobbies to underside) and the hard plastic container (hard plastic compartment has drainage holes that lead directly to top of electrical switches) is designed like a strainer. Replacing electrical switches cost me 2. I cannot use the beverage holders as I inferred that they were designed to use, to not only hold my beverage in place but contain it from leaking above any sensitive exposed electrical switches. I understand the same design is in the chevy equinox this year. Good luck. |

| Description | I have a 2018 chevrolet colorado 3. 6l. I have had a rattle noise on cold start that would happen every so often. Now that I'm 1k miles out of powertrain warranty this rattle noise happens just about every time I start my truck. It is caused by the variable timing actuator on the camshaft. I am an automotive technician, and I'm very familiar with variable timing actuators. The problem is the lock pin in the actuator does not function properly when you turn the vehicle off causing it to drain all the oil out of it. This causes the actuator to rattle around until it get oil pressure. This will eventually causing issues with your timing chain and other components internally in the engine. Very disturbing that gm keeps making vehicles that work fine, usually, until they have gotten out of warranty. Let me also state that I regularly change my oil with the recommended oil and well before it's due. Not very happy! |

| Description | I am writing to inform you of a safety issue with my 2018 chevrolet colorado. When putting the vehicle in park the ignition key will not release. Chevrolet doc# 4811390 documents a fleet wide problem with the colorado. There has been no re-call issued by chevrolet to correct this safety issue. I got my colorado repaired at a cost of 2. 15. I looked at the shifter that was removed from the truck, and found that the micro switch that activates when the vehicle is placed in park had a broken mounting post causing it to be misaligned. I have included pictures of the switch and mounting post. *js |

| Description | My colorado has completely shut down/powered off when making a right hand turn. Twice now. I'll be coming to a complete stop, accelerating through the turn and then all of the sudden, without warning, the truck loses all power. No flashing dash, nothing. I have to coast to the shoulder of the road, turn on the hazards, put in park, and restart the vehicle. This has happened twice now. From some online forums I've read, the problem only seems to get worse and has happened to others around 30-40 mph. My car is still under manufacturing warranty for another 500 or so miles. I took my truck into a certified chevy repair shop and after a week of troubleshooting and trying to recreate the problem, they have found "nothing" wrong with the car. If this doesn't get fixed and continues to occur, it's only a matter of time before an accident happens. |

When I researched this issue, I found thousands of issues online that matched this problem 100 percent. It is called the chevy shake or the gmc shutter. Mind you, the dealership verified that they have been sent kits from gm to correct these issues. It's called the tcc shudder. |

All electrical shuts off just like I had turned the key off. All lights off, ac off, radio off, engine off, everything off. No warning lights, nothing - just turns off. Vehicle restarts fine with no immediate recurrence. For some reason it simple turns itself off. It's going to be bad if this happens when pulling out into traffic. |

From low speed, it doesn't downshift to accelerate unless the pedal is floored. Also, there is hesitation/pedal lag from a standstill, which makes it unpredictable when trying to pull into traffic.

Sometimes the vehicle feels like it is coming apart it shakes so hard. When the vehicle was two months old it stopped on a city street in arlington va and was undriveable. After a timeout period of 10-15 minutes it was driveable but at 10 mph it whined as if the transmission or engine was going to blow up. At 20-25 mph it was a screaming demon and had to be towed to the dealership (browns) who found no record in car computer system of fault. Battery or electrical system was completely dead on 7 june 2019 with about 10,200 miles. Dealership knew I had appointment and I asked for tow but they don't provide a tow from reed-lallier. Onstar was of little help so I called my usaa insurance roadside assistance to get truck jump started; I missed appointment and they canceled appointment that morning which was to check for shaking and also 2nd oil change. Gmcustomercare took my concerns and asked my resolution which was check battery for bad cell, be aware of first transmission problem in arlington va and the current problem of vehicle shaking.

Why on auto it wants to freeze us at 72 and temp has to be adjusted up?

Then that evening as temp had dropped, when turned on truck it blew hot then cold then back to hot. The blending that the system is doing is not working correctly.

| Description | Brand new 2018 midnight edition chevy colorado less than 24hrs on the engine and had less than 900 miles on it. Went to go to work one morning and it wouldn't do anything. No revere. No power steering. All lights and gauges were flickering and going crazy. Engine was chugging and making odd noises. It would not move from my garage/driveway. Had it towed it to nearest dealership. Over 2 weeks of diagnostics it's either a steering module or a wiring harness part. Dealership tells us its faulty wiring/steering module. It is an intermittent issue and it's hard to diagnose. I really feel that this could cause many safety issues since power steering was completely out and it wanted to shut off on us. This could have been bad if it happened while we were driving it to work. The dealership we purchased it from had done some electrical work but did not disclose what was done until it quit working and was brought to a different dealership. They brought it to our attention when it was towed in. The wiring that was done before purchase is what's causing all issues electronically. Truck is currently in the shop waiting for a part that is on backorder. Waiting for paperwork after repairs are completed. If they can be completed. They're still trying to fully understand the electrical issues since it is so random. It has been in their shop for over 2 weeks now. I just want someone to be aware of these issues incase it needs to be recalled. This could be a scary issue if it happens while driving. |

The check engine like comes on, the vsa, and t/c lights all come on and a notification on the dash saying stabilitrak is disabled. The vehicle shakes terribly. The check engine light will flash and then go solid. I am an automotive technician. I know that a misfire should set a hard dtc. When the vehicle is turned off and started several hours later there is no check engine light or any other light on. The dealership in marysville, oh had my truck for 3 days and told me they cleaned a bunch of terminals at several connectors. Whatever that is supposed to do. They said they started the vehicle several times after and everything was good. The next day after I picked the truck up, it did the same exact thing! Extremely frustrating! I know a continuous misfire let's unburned fuel into the catalytic converter which leads to premature breakdown of the catalyst. So my question is what is being done about these issues? Another issue is with the transmission. On a cold start there is a clunk noise. Then when you are driving at cruising speed and you let off the throttle and depress throttle again there is a shudder. Also, when you come to a complete stop the vehicle tries to jolt forward. This is extremely concerning especially on a vehicle with roughly 18,000 miles on it. This needs to be addressed promptly!! |

| Description | Loose rattling sheet metal or other parts in drivers door pillar near sidewall airbag area. May cause serious injury if it inadvertently deploys airbag, or restricts airbag deployment in an accident. Gm has been notified of this defective problem on all colorado and canyon models since 2016 with no actions. Other dealers have used expanding foam to attempt to secure loose parts to prevent the noise. This may hinder airbag deployment if not addressed. |

| Description | Chevy colorado a bad vibration in drivetrain. Took truck to dealer who said it was torque converter problem. It has been at dealer for 9 days because they are doing 9 vehicles a day for this problem. Supposedly they are going to change torque convertor, others they just change the oil in torque convertor. This is done approxmately 9 times a week at this one dealer, ross downing in hammond, la. This is the 8sp trans. That is used in several gm rear drive cars and trucks. My truck only has 6300 miles on it. When trying to pass vehicles on interstate it vibrates so bad over 70 mph I am afraid to wreck. Others I have talked to at dealership claim there vehicle vibrates at lower speeds, surges and making noise. This dealership doing 9 a week, that probably is several thousand a week statewide. This is a terrible problem that needs fixin. Many thanks. |

| Description | The bottom seat cover retaining clip keeps coming loose on both the driver side seat and the passenger side seat, and can start to tear the seat cover. This appears to happen when entering or leaving the vehicle. It can be clipped back, but quickly comes loose again. I have returned it to the dealer for repair; they put the clip back in place, but it quickly came loose again. I have put it back on and it continues to come loose. |

| Description | Upon accelerating the vehicle onto a 3 lane road, all warning lights came on in the vehicle. A warning message presented on the dashboard stating "engine power reduction" and then the vehicle shut down completely while moving. The engine shut off and the vehicle would not disengage from park. Vehicle had to be towed from the location. At the dealership, the dealer informed me the engine throttle body and intake tube duct hose should be replaced. He also informed me gm is aware of this issue with the vehicle and has not developed a permanent fix for the issue. |

| Description | While driving home, yellow check engine light came on & I noticed reduction of oil pressure. Parked in driveway, shut off engine, went inside. Upon returning, noticed significant amount of oil on driveway. Dipstick showed no oil. Towed to dealership. They verified leaking came from defective oil cooler line hose. Waited several days for replacement part. This is a new 2018 colorado z71 with only 5k miles on engine. And, this is a systemic problem that gm has known about since 2015 and impacts both colorado and canyon models (there are several complaints on web). This is a dangerous problem and should be investigated before someone gets hurt. It was not a slow leak. Obviously, it is manufacturing problem. Additional information (invoice and pictures) available upon request. |

| Description | I had truck stationary parked on a slight incline on a dirt road for about 5 minutes when I heard a odd sound like "arrrrr clunk" and my car rolled down a hill. I had my car on park while on 4low with the engine off. I did not have my parking brake on though but the incline was so slight I feel I did not need it. My truck was not loaded with any extra weight or anything to cause it to roll down the hill. I truly believe I am not at fault for this happening it is a brand new car how could this happen? Prior to this I was not doing anything extreme to damage my car in any way. Something must have failed on my truck. |

| Description | The display for the backup camera is on at full brightness. There is a control knob to dim the interior lighting and display, but when the vehicle is put into reverse, the display goes to full brightness and cannot be controlled by the brightness control knob. At night, the passenger side mirror is not useable since the backup display is so bright. This almost resulted in accidents when backing up into a parking spot. |

2018 Colorado with transmission problems . Took the truck to Chevrolet dealership while truck was under warranty and they did a transmission flush that corrected the problem . The same problem occurred about a year later at 78000 miles and the truck is out of warranty due to mileage and now they want to replace transmission at my expense. They said it might can be corrected by replacing torque converter only but still an expensive repair
I have a 2018 Z71 Colorado and it shakes and vibrates. I have taken it to the dealer and have been told change tires. I changed tires. I took it back because it was not the problem. I took it back for a second time and I was told they (my tire guy) needed to look at the tires again because the balancing was not correct. The tire guy looked rotated my tires and balanced them again (told me nothing wrong with balance but showed me his guys would go ahead and rebalance). I am taking it back for a third time before warranty runs out. Stay tuned……..
thanks for your complaints .i was going to buy a 2018 colorado .but since i read this i wont
I purchase a 2018 Colorado and I took it for a very short trip to the beach this weekend and the whole way over there the truck was shuddering and vibrating. I have called the dealership and I keep getting the run around and cannot even get a decent call back. HELP! I have left numerous messages, I do not have time to deal with these people as I am a fulltime employee and a single mother of three. This truck is my ONLY means of transportation.

I just want them to come get and terminate my lease do to the know problems.
Help
Have had truck to two different dealers 5 or six times for vibration getting run around for over a year
My first truck. Traded it in at 3000 miles. Shuddering, fogging up from the inside in cold weather, and very squeaky brakes. Dealership was kind of helpful but just wanted me to buy an extended warranty. How about you give me a car that runs correctly if I’m spending that kind of money!
2018 colorado and the transmission is horrible.
It shakes and shutters and is the worst truck i have had.
I believe its a lemon and the dealers are no help.
