Vehicle speed control, Engine, Fuel/propulsion system, May 28, 2026
After driving my vehicle for a short period of time I stopped to go shopping. When I returned to my vehicle I started it as usual and the check engine light illuminated. I began driving and within 0.25 miles I received an info enter message that stated my vehicle would have reduced acceleration and to please drive safely. My engine fans became noticeably louder and ran the entire trip home (about 15 minutes). After pulling into my driveway I sat in the vehicle and listen to the fans continue to operate. Additionally, my OnStar system, WiFi, and navigation systems quit working. A P1098 Code was returned when using a diagnostic code device. Disconnecting the battery would cause the check engine light to extinguish and for the truck to operate without reduced acceleration; however, OnStar, navigation and WiFi would not work. After shutting off the engine and then restarting the check engine light would once again illuminate and the reduced acceleration message reappeared.

This vehicle has experienced repeated catastrophic engine and drivability failures since purchase and has now undergone four engine replacements under warranty. Despite these major repairs, the vehicle continues to experience dangerous shutdown/stalling conditions. The primary safety issue occurs while braking or coming to a stop. The engine will suddenly shut off unexpectedly, creating a serious traffic hazard and leaving the vehicle unable or difficult to restart. This has occurred multiple times and creates a dangerous situation in traffic and at intersections. The vehicle remains under manufacturer warranty, however the defect has not been successfully repaired despite extensive service attempts and multiple complete engine replacements. The condition substantially impairs the safety, reliability, and use of the vehicle. This vehicle was acquired through a fleet/lease arrangement for company use and was not purchased for resale. It is a light-duty 1500-series pickup with approximately 7,100–7,200 GVWR used as a company vehicle. Complete repair history, diagnostic records, warranty repairs, and engine replacement documentation can be obtained from: Stevens GMC Bristol, Connecticut The vehicle has been repeatedly presented for repair and the defect remains unresolved. This appears to be a serious ongoing safety-related defect involving engine shutdown/stalling while braking or stopping.

catastrophic internal engine failure on my 6.2L engine. Several times vehicle was to Gm Gunn Buick GMC regarding power loss knocking noises. Received the run around that vehicle past all their initial inspection and test. They only replaced a VALVE LIFTER REPLACEMENTS BANK 2 without further assessment of the engine or components. I took my vehicle to another shop to conduct a thorough inspection and they found broken metal from the piston/skirt and likely connecting rod damage inside the crankcase. Broken piston skirt/piston material • Cylinder wall damage/scoring • Metal debris throughout lower end • Possible bent/broken connecting rod • Potential crankshaft/journal damage from debris circulation • Oil pickup area contaminated with metal Lifter failure leading to dropped valve/ piston contact • Rod bearing failure • Oil starvation • Spun bearing • Piston failure/detonation Advised GM Gunn Buick and GMC of the secondary engine inspection by another shop. Manager told me it was my issue now and they wouldn’t replace my engine it wasn’t there problem. I had to pay out of pocket for a new engine replacement due to the negligence of GM and their agency lack of maintenance and customer care and service

On April 1, 2026 at approximately 7pm the vehicle had a complete engine failure exiting an interstate. As I was slowing to exit the interstate the truck, without warning, lost power and locked up the rear wheels. I was able to safely exit onto the off ramp, but did partially block the off ramp for 45 minutes waiting on a tow truck. Once I came to a complete stop the dashboard began displaying numerous error codes, included "key missing, restart truck and shift to park, and start failure". The vehicle was part of the GM L87 engine recall but had previously passed the PICO test and was deemed OK to drive. I had the vehicle towed to the closest GMC dealership where it was diagnosed as an engine failure and the engine was locked up. The vehicle has been at the GMC dealership since the night of April 1, 2026 with no date given as to when it will be fixed. The vehicle had displayed no signs of any problems prior to the engine failure on April 1, 2026.

Driving on the highway and the top section of the grill (approx 4" x 50") broke loose and went over the cab of the truck. The piece didn't hit my truck or any other vehicle, but the driver behind me swerved to avoid it. All of the clips that hold the chrome piece to the vehicle are still attached to the body. I made contact with the local dealer's service dept. and was told my VIN was not in a recall for this issue. I contacted GM customer care and was told the recall hasn't been extended to my vehicle and that I would have to pay for the replacement. IF GM extends the recall to the other known issue model years I could be reimbursed. There seems to be numerous other complaints of this issue that aren't covered by GM.

I was driving at 65mph through a construction zone on my local freeway - through a construction zone. With cruise control on, my upper bezel portion of my grill detached. It slammed into my windshield and hit the semi behind me after bouncing off the road. Luckily, neither of us swerved drastically. However, with workers in the area, this could have been a catastrophic event. After contacting my local GM dealership, I was told "yeah, that just kind of happens from time to time". When relaying that information to the GM Customer service team, they told me to ask for a courtesy credit from the dealership as I was out of warranty on bumper to bumper. There were no prior issues with this part on my truck that I was aware of leading up to this event. It additionally caused damage to my windshield and roof.

I took my truck in for routine maintenance. When i got it back and turn the truck on, the instrument cluster was completely black. I couldn't get it to turn on. I went back into the dealer and informed them of the issue. The claimed they had not done anything electrical The dealer has told me that they are not sure why it has stopped working but they did let me know they had to replace several instrument clusters with other customers. I am unsure if they had paid for the replacement or not. I've looked online as well and seen multiple GMC truck owners having the same issue and getting their instrument clusters replaced as well. I've noticed this is happening with 2022 models and above. Please look into. Thank you

I brought this truck brand new. Had issues the first couple days of purchase that was a quick fix, but as time went on things got worse. Truck always stalling out, engine has been replaced once already due to a recall and months after the first replacement, it stalled out on me again in the middle of the freeway and I just got a call from the dealership that it needs another new engine! How is this right! How is this safe! I could've lost my life on every occasion it has happened.

OnStar module failed. Unable to fix and needs replaced. Thousands of other individuals having same issue. Car can shutdown without warning while driving. This issue must be addressed by GM.

On March 3rd 2026, I went to a doctors appointment. Halfway into the 50 minute drive, I noticed the on the infotainment screen that my GPS was still showing me being at home. It was working normally a couple days prior to parking the truck. After my Dr appointment, I did some online research and followed recommended procedure to do a hard reset of the infotainment/radio to try and refresh the signal. Didn't work so I checked the recommended fuse and it was good. Realized that the OnStar and truck's cellular/data was also not working. After more research, I found that it's a very commonly reported issue on 2022-2024 trucks. Apparently the Telematics module will freeze/glitch or fail. Took my truck down to American Chevrolet on April 13th for the Data Gateway Module recall# N242435631 and asked their service advisor if he could find out what's going on. After the recall was performed, he verified that the Telematics module is indeed dead but, because I'm at 39,000 miles, they could not fix it at no cost. The biggest reason why I've been driving this truck so frequently is because it's the safest truck we have and the Automatic Crash Response & Emergency GPS gives my girlfriend some piece of mind when traveling with our two sons. She now refuses to travel with me in the truck. I'm also upset that the cellular data is paid up until I believe March of 2027 and now I can't use services paid for but, I'm more concerned about the safety features that are no longer working. For this part to completely fail or lock up at under 40k miles is absolutely absurd. I'm going to request a Good Faith repair through GMC but, I want this to be documented. Thank you for your review of this problem.

I was driving down the road at 55 mph on 4/12/2026 and had let off the gas for a 45 mph zone when I experienced a violent downshift of the transmission that squealed the tires momentarily and felt like someone had hit me from behind. It startled me and caused me to lower my speed down to 20 mph. I continued driving to my destination and when I let off of the gas doing 45 mph for a slight curve I had another violent downshift that felt again like someone hit me from behind. I contacted a GMC dealer on 4/13.2026 to see if there was a recall on the transmission that I wasn't seeing online and was told no. I described what I experienced to their service department and was told to flush out the transmission fluid and replace the filter. I did experience another bad downshift at a slower speed (about 25 mph) on 4/13/2026. There wasn't any warnings or lights that came on when these three incidents occurred. When looking online I did see there was a similar recall for 2020-2022 GMC Sierra's where customers were experiencing similar violent transmission downshifts and am wondering if this issue is affecting more than just those three model years.

Power train, Forward collision avoidance, Apr 5, 2026
On March 13, 2026 I purchased a 2023 GMC Sierra AT4 Pickup with 3.0 Diesel Engine. While driving on a state highway in a 35 mph zone I started to accelerate as the speed zone changed. The truck suddenly had the rear wheel lock up for a brief time about quarter to half second then the truck proceeded on. This happened as the transmission was downshifting. Then on or about March 24, 2026 I was using the same truck and towing a 4,000 pound enclosed trailer. This trailer was hooked up within all recommended hookup requirements. In a 225 mile trip I experienced the same rear wheel lock up happen 4 random times during the trip. Once this happened at 65 miles and hour had there been snow or ice on the highway the truck may have crashed. This lock up happened while using the truck in tow haul mode. Two times it happened while the truck was being towed with cruise control active and two times it happened while not using cruise control. Truck was brought to Authorized GM Dealer and inspected and truck had no stored codes from transmission related issues. Dealer blamed this for using cruise while towing. I informed dealer this happened while not using cruise as well. Was told to turn off adaptive cruise when towing. I was unable to find anything in the GMC Manual regarding not using cruise while towing. This appears to be an issue with the valve body in the transmission and customer explained this to the dealer but they denied this claim. When these quick moment lockups happen no codes or engine lights show everything on dash appears normal. Customer is bringing truck to another GM Dealer to be tested and examined.
