The contact immediately drove to the dealer and the vehicle was diagnosed. The dealer retrieved a DTC code for power steering failure. Additionally, the contact was informed that the instrument panel needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the dealer and the repairs were completed another time; however, the failure persisted. The manufacturer was notified of the failure and a case was opened. The approximate failure mileage was 10,200.

10/9/24: All interior vehicle sounds (turn signals, hazard lights, parking warnings, collision warnings, etc.) along with the audio sound system, are audible in my vehicle via the vehicles’s audio system speakers. For reasons unknown and without warning, all interior vehicle sounds and the audio sound system cease to make audible sound; however, the infotainment display screen and the instrument cluster screen continue displaying normally and appear to function properly (system still accepts touch screen inputs and visibly displays volume knob input adjustments). So, in summary, a disconnect occurs between the infotainment system / vehicle audible warnings and the vehicle’s speakers, through which the sounds emitted. We purchased our 2024 GMC Sierra 1500 AT4 as a brand-new purchase on 9/30/24 and it is completely stock, with no post-purchase or aftermarket alterations having been made to the vehicle. This issue has occurred on two separate occasions since the purchase date, with the occurrences happening on 10/8/24, and once on 10/9/24. When this sound-disconnect issue occurs, it will last indefinitely until we remedy the issue. The only remedy for this issue that has worked thus far requires that we completely shut the vehicle down, wait a few minutes, and then restart the vehicle. In researching this issue, I have found multiple comments over various forums by various users who have reported dealing with this same issue.

The DIC randomly displays “check trailer wiring” then says “brakes connected” over and over. When this happens the brakes on the trailer quit working, all lights continue to work all the time. It hasn’t been back to the dealer yet but I will take it when I can. Other vehicles have no issues with this trailers brakes when towing. I have replaced the trailer pig tail 7 pin plug, cleaned all connections etc. The only thing that works so far is to disconnect one of 4 electric brakes then the DIC is silent and 3 brakes function. I even replaced some magnets in the trailer brakes but they were working prior to the DIC message that began on my second towing trip. There is a technical bulletin for some GMC trucks but my model isn’t listed as one. I believe it to be the controller or software since nothing seems to work as far as the trailer is concerned. It isn’t my trailers issue…I know they are going to say it is.

To Whom It May Concern, This is a brand new 2024 GMC Sierra AT4 Diesel Truck with 4,000 miles. The first incident occurred when I was doing about 5 mph. The truck maintained its speed without my foot on the gas pedal and the cruise control was not on. Then when I tapped the gas pedal, everything return to normal. The second incident was about 2 weeks later in which the same thing happened. The third incident which was about one week later, I was doing about 5 mph and the truck accelerated on its own. I let the truck accelerate to approximately 28 mph. At that point I hit the brakes to stop the vechicle and pulled over. The truck was idling very high so I turned off the engine. All the ignition lighting remained on, but the truck would not restart. Even after removing the keys from the vehicle the ignition lighting remained on. At that point the truck had be towed back to the dealership which is Rainbow Buick, GMC in Covington, Louisiana. I've been told by the Rainbow Service Department that they do not know what's wrong with the truck. It's been sitting there for 10 days now was a dead battery. My salesman who I don't really believe, said he has the exact same truck and it happen to his tuck at 30,000 miles. I file a claim with GMC Customer Support but have yet to hear from them. I'm obviously very disappointed with my new truck, my salesperson, and service department. If there's anything you can do to help please let me know!

I was driving my vehicle, with my 9-year-old son in the back, when it seemed to completely lose power and shut down (while I was driving!). The power steering, brakes, and gas all gave out. I was able to steer myself toward the side of the road where I waited for a tow. The vehicle would not start, nor would it shift into neutral, which led to towing challenges. This is a 2024 vehicle that I've had for about eight months, and it completely gave out while I was driving with a child in the back, which is a significant safety concern. Nobody at the dealership or GMC is able to offer anything with respect to information on how or why this happened and what you are doing to resolve the issue. From what I see online, this is a known issue that GMC is likely to be sued for in the future.

Status: open (inferred from source dates) · Engine
On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001. This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement. Additionally, ODI has received 191 reports of L87 engine failures in engines produced after the production period cited in Recall 25V-274. GM reported receiving 6,953 complaints of post-remedy engine failure. ODI is opening this Engineering Analysisto continue investigating complaints of post-remedy engine failure. ODI is expanding the scope of this Investigation to include engines produced after the production period cited in the recall.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.

These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE.
