GM 6.2L L87 was recalled. I took the truck in at 32,000 miles. GM dealer perfromed a Pico Test, motor failed. Motor replaced with "NEW" crate motor. I was without a truck or loaner for 3 weeks. Dealer called me when new motor was almost complete. First they said it would be a couple more days because they started the "NEW" motor and it had no oil pressure. They contacted GM Tec and they tested it again, it tested with too-high of oil pressure. GM then instructed them to replace the oil pump on the "NEW" Motor. I got the truck back a week later after being in the shop 3 weeks. I drove a total of 1,200 miles, 400 miles we're highway in one long trip. The balance was local. I went to start the truck one morning after it sat all weekend and the "NEW" motor was knocking like an old diesel. I video'ed it and sent to my service advisior, I was advised to bring it back again. Vehicle has been at dealer now 9 days, dealer took oil sample from "NEW" motor, it was found to have metallic matter in the oil. They contacted GM Tec again, it took GM Tec 3 days to respond, Last Friday GM Tec said pull the oil pan and take pictures. As of the typing of this email I have no loaner because there's a wait list for loaners, GM will only reimburse me $25/day for a rental and a truck rental is $105/day which I refuse to pay for GM's defects out of my pocket.

Today it died while I was pulling a trailer with a RZR on it. I had drove about 90 miles with a stop midway when I did have the engine turned off. Then it just quit. My vehicle only has 13k miles on it. Not sure if police report was filed but they were called and there directing traffic because it stopped in a busy intersection. I had to be towed, and pay a separate fee to have the trailer towed. At 1000 miles on the truck it had to be taken in for an infotainment screen replacement.

I purchased a 2024 GMC SIERRA 1500 Denali Crew Cab Diesel 3.0L After several times bringing the truck to the dealership I purchased from and conduct all service related work. They finally found a crack/whole in the sidewall that was not done by any road hazard to cause damage but looks like a manufacturer defect. This is now not only prominent on one tire but two of the tires. The area is on the covex area of the tire. BRIDGESTONE ALENZA A/S 02 Size 275/50/R22 This is a huge safety concern as a blowout at 65MPH could cause significant harm to not only people in my vehicle but to others. This is an advisement to get the right attention on this before something catastrophic or deadly. With plenty of tread on the tires (6/32), which equated to 50% life on the tire. The dealership is trying to make me pay for a manufacturer defect of $600+ for the two tires.

I was driving and lost engine power in the left lane of a freeway, cut across traffic and coasted to the shoulder. Had truck 6' off of road, though with semis and cars passing at 70mph, I left and waited in the ditch for the tow truck. The electronics worked, but the engine was dead and would not start. When the tow truck arrived, the wheels were locked up and they used rollers to haul the truck to the dealership. After the dealer inspected the truck, they sent a message saying they could not turn the engine over by hand. The engine had metal shavings in the oil filter and after removing a valve cover, found metal contamination circulated throughout the engine. The engine, radiator, oil cooler lone, and battery junction box all require replacement. This truck has a 6.2L L87 engine, and the dealer has had several other vehicles with the same blown engine failure. The truck was in for the recall on this issue about a month before the engine went out, they placed a pico scope in the engine to check the drive shaft, and then added a heavier oil. No warning lights came on until the engine died.

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.
