I received a notice months ago for possible engine problems. my dealer checked it out and everything was good except for changing oil from 0W-20 to 0W-40. i was in Atlanta, GA on 8/26 and by the time i got home on 8/27, engine was knocking. I barely made it home. the dealer has had the truck since. they said i have to have a new engine. no idea when they will get one inn or when i will get my truck back. i opened a claim with GM (Case #108927907). GM basically offered no assistance, help, etc. i even tried to trade the truck back to my local GM dealership for another truck and they wouldn't offer enough on trade inn (says they wouldn't be able to sell it), GM Corporate wouldn't offer buy back, loyalty program money, etc. as they claim it's under a recall. I have never received anything about a recall for the engine. local Ford or Toyota dealerships will not even consider taking it in on a trade after new engine, says they cannot sell because of engine issue with 6.2L engine. so i'm stuck with a truck that i cannot sell or trade and is now worthless. I'm sure the new engine will fail as well.

My vehicle is under the L87 Recall from GM for engine failure. In September 2025 it was given the recall “fix”, different thicker oil. But on July 1 2026, my engine seized while I was driving 60 mph on the highway. GM has since replaced the entire engine and the radiator. But the “fix” obviously did not work.

On 8/31/2026 at approximately 2330 hours I was driving my 6.2L Sierra home. I took a left hand turn and the engine stopped. This happened with zero warning. I attempted to restart the engine after coming to a stop and the starter clicked once and nothing happened. Had it towed to my dealership for service. I was told the engine seized and will need to be replaced. I went through the recall process earlier where I was told my engine passed inspection and the oil was replaced with heavier weight oil and I was told it was good to go.

Back to 0W/20 oil. Since ownership, I have to on a regular basis reset the Collison Warning from Seat Vibration to Beeps. It appears to reset back from Beeps to Seat Vibration every time there is an over the air software update. It might even just randomly reset. I cant tell for sure. I recently had a small backing accident were I was expecting the Beeps to alert me. I mentioned this to my auto insurance company. They told me this was not the first time they have heard of this type of situation.

I was driving home from family’s house 2 hrs away and got home late. When I got home I noticed the upper front grille assembly or top chrome trim piece for the 2024 GMC Sierra 1500 Denali Ultimate flew off at some point while driving. That could have caused an accident for others and myself but luckily no one is harmed.

I purchased a new 2024 GMC Sierra. I brought it to the dealer for the engine recall on the 6.2liter. It passed the inspection and the oil was changed to a heavier weight. After the recall was satisfied and the oil was changed to the heavier weight, around 45,000 miles, the engine failed at highway speeds while pulling a trailer and left my entire family stranded on the side of the highway; late at night. The engine completely failed and would not re-start. After researching the issue online and watching mechanics tear down these engines and suggest the problem, I believe that GMC has created great harm to the customers who've purchased the vehicles with 6.2L engines by allowing us to drive hundreds of thousands of "ticking time-bombs" across the country. Furthermore, it is absolutely infuriating to learn that problems clearly identifiable starting in 2021 were not addressed until a recall in April 2025. I strongly believe that G.M. has mishandled this information and put customers into vehicles that are verifiably unreliable and should correct the problem/take the hit to replace these faulty engines. !!TIMEBOMBS!!

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.

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.
