  The contact owns a 2024 GMC Sierra 1500. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the recall repair failed to prevent a failure from occurring after passing the PICO Test. The contact stated that while driving 20 MPH, there was an abnormally loud metal clashing sound coming from under the hood. The vehicle was taken back to the same local dealer where it was test-driven, and the vehicle failed the new PICO Test. The failure mileage was approximately 23,400.

  Subject: Complaint — 2024 GMC Sierra 1500 Denali, Upper Grille Deflector Detached at Highway Speed. To the Office of Defects Investigation, I’m filing this complaint regarding my 2024 GMC Sierra 1500 Denali. While driving on the freeway at approximately highway speed this afternoon, xxx, the upper grille trim piece located above the grille and in front of the hood spontaneously detached from the vehicle with no warning and no prior impact. It created a road hazard for other motorists. This matches the failure pattern described in Recall Query RQ26003, opened xxx, covering 2022 through 2024 Sierra 1500s. My truck is a 2024 and is not covered by Recall 25V-060, which only addressed certain 2022 models. I’m concerned the defect is not limited to the originally recalled population, and that the 2025 remedy may not have resolved the underlying attachment-point failure. I request that NHTSA include my vehicle and all similarly affected 2024 trucks in any expanded recall or investigation, and that GM be required to provide a free repair. Vehicle: 2024 GMC Sierra 1500 Denali. VIN:xxxxxxxx. Mileage: 64,952. Date of failure: xxx. Location: [XXX]. Thank you.

  My truck has experienced recurring diagnostic trouble code P244B on [XXX], [XXX], and [XXX], 2026. The latest occurrence included a check-engine warning and reduced engine power. On [XXX], at 40,833 miles, Neil Huffman Chevrolet GMC in Frankfort, Kentucky, diagnosed a damaged diesel particulate filter differential-pressure sensor connector. The dealership's written estimate states that the connector had shorted, begun melting, and had broken wires at the back of the connector. I am concerned about the cause of the electrical overheating, the possibility of additional wiring damage, and the risk of unexpected reduced engine power while driving. I have also experienced intermittent transmission-related warnings and communication fault codes, although I do not know whether these problems are related. I understand there are GM technical bulletins addressing wiring-harness damage on certain 3.0L Duramax vehicles. I am not claiming these bulletins establish the cause of my failure, but I would appreciate having my experience evaluated for a possible safety-related defect trend.

  My vehicle has the loss of propulsion recall 25V-274. It was in for service on 5-12-2025 with NO REMEDY YET on my paperwork. 8-6-2025 the truck was in for service and passed the test that would have required immediate engine replacement. As per the recall, I was given different oil as a remedy for a faulty engine. Despite passing the test, I still lost propulsion on 6-11-2026. I was traveling on the highway at night, crested a hill and noticed while coasting that the engine was not running and the dash said "hit the start button again." When I did this everything turned off including the lights. I was still traveling at 65 MPH without lights. Luckily I didn't panic and the lights came back on when I hit the start button again. Once the vehicle coasted to a stop; and I put it in park the motor restarted. This incident was reported on 6-14-2026, complaint number 1174-4867. When I submitted this complaint, I started that GM needs to make a change so hitting the start button when the engine has stalled doesn't turn the lights off. The vehicle was towed to the dealership, they had it for two months, put around 1000 miles on it and returned it to me with no repairs made because they couldn't reproduce the problem. They returned it to me on 7-29-2026. They did not to the engine. I radio repair was unsuccessful so it went back to the dealer that same day. 8-10-2026 Vehicle return without repairs to the radio or engine. 10-10-2026 On my second drive on the highway since having the vehicle returned to me, the engine shut off again on the highway at 65 MPH. After coasting to a stop, the engine would not restart and it was towed to the dealership. They have the vehicle and are repairing the engine. My concern is that this vehicle passed a loss of propulsion recall, still had loss of propulsion twice. I have concerns for my safety in this vehicle. I do not have confidence the current repairs will not result in another loss of propulsion.

  My 2024 L87 already had the recall done and was changed over to 0w40 oil. Driving down the road at 70 mph the engine just shut off and I had to coast to the side of the road. Checked engine codes and found p0016. Had to have the truck towed to the dealership where they replaced the engine. Clearly the 0w40 did not fix the problem.

  I was driving 65 MPH on a one lane highway, right when someone went by in the other lane. My front hood moulding (hood trim piece) flew off and hit my windshield. Then drug across the cab of the truck before landing in the road. This debris was now in the road causing other people to have to swerve to miss it. I turned around and put my hazards on and grabbed it from the middle of the road. This caused other motorists to stop in the roadway for me or go into the oncoming lane of traffic to go around me. The service center from the dealership I bought it at said I would have to bring it in for estimate and didn’t confirm if others have had this same issue. This happened one day ago and it has not been inspected by anyone. There was no warnings of any kind. I didn’t notice it shaking prior or anything, it just abruptly flew off.

  Driving at approximately 45 mph on Berthod Pass in CO, towing a snowmobile flatbed trailer, when dash display indicated "low oil pressure, Turn off Engine". By the time I could read that, the engine was already off and I was all over the road trying to find a way to get off the highway. I did not have opportunity to get off highway, and ended up against a barrier, and partially remaining in traffic. GM towed the car (not the trailer, I had to do that myself) to a dealer quite some distance from my home as opposed to the dealer where I purchased the truck. Then they told me they towed it to a different dealer. After recovering my stuff, I went to the dealer where the truck was, and they said they couldn't look at it for several days. I could not wait several days simply to find out it was going to be a couple of months before id have the truck back. I traded it in on another, larger GMC simply to get out of that engine. What I learned though, is that GM used that exchange to make about $20K. This was more the dealer, but they are part of GM. My original truck was priced below book, and not the book the public can see, but the book they say they go by. They paid me $51K on an $87K truck for trade value. Then they sold the new truck at full price, no break. I was in disaster mode, as I had a large family gathering I was preparing for at our cabin, and did not have time to fight with them. The reason for the low book trade-in value was that the value of these trucks has plummeted because of the very reasons I was replacing it, GM's failure on those engines. My original truck had about 30K miles on it when it blew. The dealer told me that the one I was replacing it with (2026 Sierra HD with 6.6L Turbo Diesel) would get similar mileage, but that was untrue. I get about half the mileage I got in the first truck, and the price of diesel is about 20% more than gas. So they found a sucker on the first truck, then that same sucker bought the second one.

  At approximately 2 years, 47,000 miles I received a message that I needed to service the transmission soon. I then got a message "Trailer Brakes Disabled Service Required" and another "Service Transmission Now Unable to Shift Soon". I brought the vehicle into my closest GM dealer and they said it is a faulty shift control lever. These are known to have a fault from the factory, but since I am outside of the 36,000 bumper to bumper, they will not cover the cost. It took about 2 months for the part to come in as it was on back order, and now they want $1000 to replace it.

  The contact owns a 2024 GMC Sierra 1500. The contact stated that while driving 55 MPH, the message "Reduced Acceleration" was displayed and the vehicle decelerated quickly, and the contact was forced to pull over to the side of the road. The vehicle was taken to the dealer on several occasions to be diagnosed. During the first visit, the dealer stated that a transmission error code was retrieved and was cleared before the vehicle was returned. During the second visit, the dealer stated that the engine was consuming an excessive amount of engine oil and recommended that the engine be replaced. The contact stated that the message "Reduce Acceleration - Drive with Care" was displayed, and the vehicle went into LIMP Mode. Occasionally, after shifting to drive(D), the engine revved but the vehicle failed to respond, and the vehicle was taken back to the dealer. The manufacturer was notified of the failure. The failure mileage was 74,200.

  2024 Vehicle is part of the massive GMC 6.2L engine recall. The vehicle was called into the dealership on 1/6/2026 (10,437 Miles / 320.9 Engine Hours) for recall evaluation. Testing indicated vehicle was NOT a candidate for a new motor so oil and oil filter were changed to 0W-40 and I was sent on my way. Vehicle started a tapping noise at idle. Dealer advised the next week was the soonest I could be seen so I set up an appointment for Monday 8/31/2026 . I used the vehicle on Saturday [XXX] and while returning home it began making a racket emitting all types of terrible noises. I was only a few miles from the dealer so I limped into the dealship and left the vehicle on their lot. I spoke to the dealership on Monday 8/31/26 and was advised the vehicle would be evaluated later that day. I spoke to the dealership on Tuesday 9/1/26 and was advised the 6.2L engine had failed (13,591 miles) and parts had been ordered. Dealer advised it would probably be 6 - 8 weeks to get the truck returned. I am a trailer boater and also pull a trailer with a side by side. These activities are why I own a truck. Dealer advised I could get a loaner vehicle but that it was illegal to tow a trailer in Illinois with dealer plates. I ended up trading the vehicle for a new truck and suffered a large unplanned expense ( $20,537) as a result. Since the vehicle had failed and was not driveable it was impossible for me to go elsewhere to trade in this vehicle to a competitor. As a result of the failure I feel I was held hostage to buy another GMC. The vehicle did not show any abnormal gage readings or dispaly any warnings.

  I am reporting a catastrophic engine failure on my GM vehicle equipped with the 6.2L L87 V8 engine. This failure occurred AFTER the official recall remedy (Recall 25V-274/ GM Recall N242494000) was performed on my vehicle, which directly aligns with NHTSA's active investigation under Engineering Analysis EA26005. The recall service was completed by an authorized GM dealership on XXX at 22,489 miles, the vehicle had the L87 Engine Loss of Propulsion recall completed and the PICO L87 Diagnostic Testing was completed and passed with recommended updated oil change to Mobil 1 Supercar 0W-40 (19432866) quantity 8 with 12737081 Filter and Cap Changeout. On XXX, at 26,752 miles, the engine suffered a catastrophic total mechanical failure. While driving, the vehicle experienced a sudden loss of motive power and a complete shutdown with no prior warning of any kind while driving down [XXX] at approximately 45 to 50 MPH. This created an immediate safety hazard on a public roadway. The vehicle was towed to Key GMC in [XXX] where technicians confirmed Engine Seized Up. Spun connecting rod bearings at cylinder 7&8. The vehicle was at the dealership awaiting parts for repair for 65 days due to engine backorder (engine, radiator, starter, cooling lines and miscellaneous parts ultimately replaced). Because this failure occurred after GM's official remedy was implemented, the recall clearly failed to correct the underlying safety defect. I request that NHTSB include this incident in its ongoing evaluation GM's 6.2L engine issues under EA26005. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

  On 9-5-26 while on interstate 75 going about 75 miles per hour truck started losing propulsion and speed started dropping. No warning light or anything. Navigated over to shoulder turn truck off for about 5-10 minutes and started back. On 9-8-26 on the way from Dr. appt. starting truck up it acted like it didn't want to start but did. Eventually stopped at red light and truck died and wouldn't start. Dash board lighting up and when trying to start the engine would not turn over. No warning light or anything. Truck towed but had to drag on the wrecker due to wheels locked up. On 9-16 GMC advised engine fail and will need replacing at 12,000 miles. VERY UNACCEPTABLE FOR 2024. Truck was bought new in October 2023 with 4 miles. Found out it is a known issue with the 6.2 V8. Be careful. We could have been killed in the flow of traffic and truck losing power with no warning. Couldn't even turn hazard lights on or anything. 18 wheelers coming all around and we trying to navigate to safe spot on the shoulder when we was on the interstate.

  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.

  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. GM reported receiving 6,953 complaints of post-remedy engine failure. ODI will close this RQ and continue to investigate complaints of post-remedy engine failure for Recall 25V-274 as part of an Engineering Analysis (EA26005).

  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.

  On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. 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. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007).
