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.

The truck has shut off driving 5 times total and 3 different days, I was going down the interstate, and Hwy. Speeds were ranging from 45 to 70, this is the 3rd time in the shop. At two different dealers.

I own a 2024 GMC Sierra 1500 Elevation. The front upper grille molding/trim has become loose and is separating from the vehicle. The attachment points/clips are no longer securely holding the molding in place. I am concerned that the molding could completely detach while driving, particularly at highway speeds, creating a road hazard for other motorists. The vehicle has not been involved in a collision or other event that would explain the failure. I have photographs documenting the loose molding and believe this is a potential safety defect that should be investigated.

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. GMC need to get their stuff together, you are putting people lives is danger. GMC is feeling our anger right now. Who wants a new engine in a $90,000 top of the line truck

I was driving my truck and I had a sudden loss of power. The engine sounded like a rattle of bolts. It was towed to the dealership and they replaced the engine.

I did not have anyone tell me about recalls concerning my GMC SLT, when can I have what ever it takes to send me info concerning lifters, these have not had any issues yet. Will I have someone to contact me about possible lifter issue. Current miles are 18129. Thanks for your attention. MCG

As I was driving down the road, I heard a loud explosion. I looked around, didn't see anything that could've hit the truck. I thought it was possibly a gunshot that went off. After driving for another 3 or 4 minutes, I heard glass going everywhere. It was the moonroof that exploded. Thankfully, the sunroof cover was in the closed position. Otherwise, glass would've been all over the interior of the vehicle. I called the dealership to report the incident and to see if this was something that could be covered under warranty. I'm still waiting for a call back. I then called my insurance company to report what happened. I was told to seek a repair shop and collect all receipts for the claim. No warning lights have appeared in the vehicle yet. Since we were driving home from a vacation, we stopped and got a roll of vinyl sticker to cover the outside from rain.

While driving on the highway, i went to pass someone and there was a big shutter in the engine and then a load ticking noise from the engine after. All of the lights came on and the vehicle was running rough
