My 2023 GMC Sierra AT4 with the 6.2L L87 engine is showing signs of premature engine issues despite passing the recall inspection. I hear persistent lifter chatter, which is known to be a precursor to catastrophic failure in these engines. I no longer feel safe driving this vehicle due to the known defect with the crankshaft, rods, and valvetrain. GM issued a recall, but it appears to be incomplete and does not address the underlying issue in many vehicles, including mine. I am worried about sudden engine failure and safety while driving.

Driving on the highway under normal driving condition, my check engine light came on and said service transmission. This then put the truck into "limp mode" and I was stuck going 60mph in a 75mph zone. Dealership scanned and found that the coolant sensor control flow valve is faulty. This part is in such demand for these vehicles that it is unknown when the part will be in.
Power train, Jul 3, 2025, crash
Vehicle's 10 speed transmission on numerous occasions has locked the wheels at high rates of speed on the highway, causing the vehicle to veer across several lanes and almost crash. Vehicle will not always engage in drive selection causing a filed accident while trying to go from reverse to drive.

I was going camping and pulling a small 20 ft trailer with my spouse and 4 young kids in the car when the truck stopped accelerating and would not go over 30 mph on the freeway and the fan started running. There was no warning light on the dash. I was then stranded 2 hour from home with my kids in a gas station parking lot and had to have the truck and trailer hauled home.

I was driving and without warning the engine stopped. Luckily I was on a neighborhood street and was just left in the middle of the road without incident. However, if I was turning on a left into traffic or on a major highway I would hate to think what would of happened. Again, this motor gave zero indication it was going to fail. It did not knock etc. Truck is currently at the dealer waiting for a new engine. This recall will lead to fatalities if others fail in this manner.

The contact owns a 2023 GMC Sierra 1500. The contact stated while driving 35-50 MPH, the message "Service Engine Soon" was displayed. Additionally, the power train warning light was illuminated. The vehicle was towed to the dealer, where it was diagnosed that the gear shift control module had failed and needed to be replaced; however, the part was not available. The vehicle was then towed to Parkway Chevrolet (25500 TX-249, Tomball, TX 77375; where the gear shift control module was replaced. Additionally, the contact stated while driving 35-40 MPH, the vehicle was sputtering. The contact was unaware of a warning light being illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the TCM needed to be updated, and an unknown part needed to be installed for transmission cleaning. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the dealer for assistance. The failure mileage was approximately 21,000.

First GMC had my car 6 weeks for a problem with the coolant control valve which failed making the truck underivable. They couldn't fix it due to not being able to get the part with a national backorder. After a few weeks having the truck back I started having erratic bucking and shifting problems and once again the engine light came on and then truck went into limp mode. Felt like the truck got stuck in one gear and was dangerous to drive. I felt unsafe operating it even to limp back to the dealer. The incident with transmission happened at high speed on interstate 95. Kinda scary. They have told me they can't fix my truck for a minimum of 6-8 weeks, but I was told that would be a miracle. So service told me probably be 10-12 weeks if they can't get the parts. If they can!

I was driving down the highway on cruise control and all of the sudden i heard a squeal, banging noise with no power to accelerate so i pulled over to the side of the road and the engine said low oil pressure and shut down and would not restart. Multiple vehicles swerved to avoid hitting my vehicle creating a safety incident with possible injury and death. No symptoms prior to the failure and vehicle was maintained according to GMC specifications at the dealer with oil changes and tire rotations. Dealer has confirmed engine needs to be replaced but after several weeks they say they are unable to replace the engine because no parts are available and no estimated repair date. This is completely unacceptable and not a timely repair. I am without a truck and still paying for the loan of the truck with interest through GM financial.

Multiple occasions where the dash lights up while driving, the vehicle will slow down to 40 miles per hour while driving and notes on the dash the truck acceleration will be reduced. It has almost caused accidents while I’ve been driving on the interstate. The truck will jerk and shake and jolt. Multiple sensors have been replaced including drive shaft, crank shaft components and cooling valve components. I’ve also been complained about burning smells and my engine started smoking recently which caused my family to evacuate the vehicle. I believe my vehicle has same issues as the other recall on GMC Sierra 2021-2024 with engine issues

Transmission locking up Was never notified about recall and my truck was never put on recall list they have gas lighted me and others with 23 models having same known issues Yes it is stuck at the dealer waiting on back ordered part but they arent aloud to inspect the gears in the transmission due to only replacing the control module Prior to this i had other failures between fuel control module to def fluid tank to shortened wire harness all of this issues make the vehicle go crazy between acceleration/ hard and no shifting which is a danger to drive and then there will be more wear and tear on other components that arent being addressed

My wife and I were traveling westbound on [XXX] just outside of Durkee Oregon, when while going up a hill with Cruse set to 72, the truck began to slow down drastically. When I looked down I was then going 60 and showing down fast. I was able to get to the side of the road and then the truck stopped, it shut off. At that point the truck has not be back on. It would not turn on and Onstar reported that there is an issue with the Engine and transmission. No warning lights came on until we stopped. Then the Engine light was on and the truck said that it was overheating but the oil temps were normal. I feel lucky that there was not much traffic. My wife and I were on the side of the road for 2 hours at dusk and in the dark with 65+ MPH traffic zooming by. Also had a impossible time tracking down a rental call just to continue to my wife's grandmother's funeral service. I just talked with the dealer and they will not have a diagnoses for me until late tomorrow. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The system that is not working properly is the transmission. It is available for inspection upon request. The safety of the vehicle, and myself, was put at risk because the transmission (once warmed up / at least 30-60 minutes of driving takes place) downshifts hard, making a clunking noise, and has at worst given the vehicle a rough nudge/jolt forward upon downshifting particularly from 2nd to 1st gear (it is a 10 speed transmission). This issue, when it occurs, will require me (the driver) to apply extra force to the brake pedal due to the rough downshift / jolt upon shift. The issue is exacerbated when quickly stopping the vehicle causing the transmission to downshift more rapidly. The vehicle's transmission flaws, of which this happens to be one of them, were being looked into at a certified repair facility (dealership). After the vehicle was in their possession 3 days, they informed me that they could not replicated or reproduce the issue. I informed and reminded the following: (1) the vehicle has to be warm and operated for I would state at least 30-60 minutes of driving before the issue arises (2) I have recorded videos of the problematic sounds of the transmission. (3) I am willing to go for a test drive to try to replicate the issue with dealership staff, but the issue is infrequent and the vehicle must be warmed-up and/or driven more than the typical "test drive" for the issue to be observed. The vehicle component has been inspected by a certified repair facility (dealership), but not directly by a manufacturer's direct representative, police, insurance representatives, or others. The transmission is also problematic in another way (rattling at low rpm's during upshift), but pertaining to safety the downshift is most concerning as described above. There were/are no warning lamps or messages. The symptoms of the problem pertaining to the transmission began occurring around 11,800-12,000 miles in my estimation.

Transmission failure upon acceleration through intersection. Engine high revved went into Low Power Mode. Was lucky to not be rear ended with sudden loss of acceleration. Truck would also not go above 40 safely.

Rear axle locked up driving down the interstate at 65mph. Had I been towing, the incident could very well have caused an accident. Truck taken to dealer and was inspected. Gave an error code of P0747. Per the dealer it was caused by a faulty valve body in the transmission. Part is on back order for months to get fixed. Truck is not drivable as it will not go out of 5th gear. Was told that the problem was found in many models from 2020-2024.

While driving my truck shut off and went into neutral. Truck restarted after cranking for a long time. Did the same thing within a mile and then started making knocking noises, turned off and would not restart. Completely dead on the road. Truck was towed to nearest dealership.

I was driving at approximately 25-30 MPH, accelerating from a stop light and I felt a clunk, heard a grinding noise and my back wheels locked up. It was snowy/icy conditions so the back end of my pick-up slid out to the right a little bit before the wheels unlocked and I was able to regain control. I could have slid off the road or into another vehicle had the wheels remained locked. The computer system then alerted me to a transmission issue and to reduce speed immediately and call for service. The pickup was then unable to shift out of 1st gear. The vehicle has been towed to a dealer and I have been informed the valve body in the transmission has to be replaced which is 8-12 weeks backorder.

I had my 6.2 engine replaced at 26,000 miles and the transmission rebuilt. The engine was contaminated with metal shavings and the transmission rebuilt for internal defects. The new engine is running fine but the reliability is a concern after reading about other customers having the same problems. My name is [XXX] . The engine replacement and transmission repair was done at Ed Martin GMC in Carmel Indiana. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While entering the highway from a downward slop exit ramp and towing a trailer, my truck shuddered hard and briefly locked up the rear axle. It immediately went into limp mode with a message that driving speed will be reduced. It also wouldn't shift past 5th gear. When the event took place, the OBD2 generated over 20 trouble codes. My local dealer advised I could drive it to them for repair. Upon dropping it off, they now advise it's NOT safe for driving and they have no eta on the parts to repair the issue. It's now been at the dealer for a week with no update. This is a well known issue that GM refuses to repair or provide a reasonable timeframe for repair. There are countless videos such as this one that show what happens when this takes place. [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

With out any warning the truck stop running at stoplight an would not start back up. We could not move the truck out of the road and blocked traffic for almost 1 hour waiting for the tow truck and getting it loaded on the tow truck (truck would not go in to neutral). The truck is now at the Dealer and they are saying that the engine seized up and will need replaced.

purchased a 2023 GMC Denali, 1500 on January 12, 2025. after about a week,Started to hear knocking ticking noises took the truck to the dealership with 20,362 miles . dealership diagnosed that the lifters on the driver side went bad dealership replace driver side bank , picked up my truck drove it a little over 500 miles and still heard knocking ticking noises. Send it back to the dealership and dropped it off dealership told me they would keep me an update on it.Emailed called have absolutely no idea what’s going on with my truck. The dealership did mention of a possible engine replacement. But did not confirm after many attempts. Trying to attempt to contact the dealership emails phone calls still no answer. Called General Motors. They informed me the dealership ordered a new engine for replacement. That definitely worried me and I asked for a vehicle replacement or refund General motors, declined my request. Now I am not so confident in my truck what else could go wrong since the engine is going to be replaced? What about the transmission? Could it affect it? I don’t know> The damage was significant in order for the engine to be replaced you just don’t replace an engine just because, there was no light indications that something was going wrong with my truck. I’m glad I wasn’t driving far when I was hearing these noises coming from the engine because the engine could have seized left me stranded who knows could have crashed if the engine came to abrupt stop because of the engine failure. I purchased this truck January 12, 2025 . The total of time that I have had my truck since January 12 has been 15 days. today is February 6 on Friday, February 7. My truck has been in the shop literally 30 days exactly. Still no update on when it will be ready. This is so frustrating and such a big inconvenience.

Valve Body. While driving the vehicle, hard shifts occurred; the vehicle check engine light came on and stayed on while the vehicle went into limp mode. I was able to link to the GMC dealer. The dealer was not and would not inspect the vehicle at that time. I was told I needed to leave or return in two for inspection. The left vehicle was inspected the next day and determined as a value body. The GMC dealer found the part in another state and has the part shipped. I installed the part, had the GMC dealer search it, and performed a recall update.
