GM Issues Recall and Stop-Sale order for Failed 6.2L V8 Engines in 2021-2024 Trucks and SUVs
After widespread engine failures and an NHTSA investigation, GM is recalling all 2021-24 full-size pickups and SUVs equipped with the 6.2L V8 engine; Chevy Silverado, GMC Yukon, and Cadillac Escalade
APRIL 2025 — thedrive.com — General Motors has issued a stop-sale order and agreed to a full recall of every full-size pickup and SUV powered by its troublesome L87 6.2-liter V8 produced for the 2021-2024 model years.
This comes after widespread owner reports of complete engine failure piled up over the last year, creating a service crisis at dealership and prompting an NHTSA investigation in January.
“General Motors has decided that a defect which relates to motor vehicle safety may exist in certain 2021 – 2024 model year Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, and Tahoe, and GMC Sierra 1500, Yukon, and Yukon XL vehicles equipped with the 6.2L V8 gas engine (RPO L87).
The connecting rod and/or crankshaft engine components in these vehicles may have manufacturing defects that can lead to engine damage and engine failure.
If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash.”
GM spokesperson provided the following statement: “GM will voluntarily recall certain 2021-2024 Chevrolet Silverado 1500, Tahoe, Suburban, GMC Sierra 1500, Yukon, Yukon XL, Cadillac Escalade and Escalade ESV models equipped with 6.2L L87 engines to resolve manufacturing issues affecting some engines. The safety and satisfaction of our customers are the highest priorities for the entire GM team, and we’re working to address this matter as quickly as possible.”
Earlier this year, the National Highway Traffic Safety Administration opened a “Preliminary Evaluation” targeting 2019-2024 GM trucks and SUVs equipped with the L87, citing nearly 350 customer complaints lodged with the agency.

GM Can’t Keep Up With 6.2L V8 Engine Replacements
GM is facing a serious quality control issue related to the 6.2L V8 L87 engine equipped by models like the Chevy Silverado, GMC Yukon, and Cadillac Escalade
GM Can’t Keep Up With 6.2L V8 Engine Replacements
GM is facing a serious quality control issue related to the 6.2L V8 L87 engine equipped by models like the Chevy Silverado, GMC Yukon, and Cadillac Escalade
FEBRUARY 2025 — gmauthority.com — GM is currently facing a major quality control issue related to the naturally aspirated 6.2L V8 L87 gasoline engine, a powerplant found throughout the Cadillac, Chevrolet, and GMC product portfolio, including the Chevy Silverado, GMC Yukon, and Cadillac Escalade, among others. Reports of engine failures have surged, leaving many owners stranded with disabled vehicles and no clear timeline for repairs. The problem has become so severe that the National Highway Traffic Safety Administration (NHTSA) has launched an investigation after receiving over a thousand complaints from affected owners, with 877,710 vehicles now under the microscope.
The failures are rooted primarily in bearing failures and collapsed lifters, both of which can render the engine completely inoperable. According to a report from The Drive, while many of the affected vehicles are still under warranty, GM’s inability to supply enough replacement engines has left owners without much recourse. Not only that, but dealers have struggled to meet repair demands as GM attempts to balance new vehicle production with replacement parts, creating an extended repair backlog.
As highlighted by The Drive, the issue is particularly impactful for business owners and fleet operators, who rely heavily on their vehicles for daily operations. As mileage quickly accumulates, often exceeding warranty limits, affected owners are sometimes forced to spend upwards of $10,000 for a new engine, with no guarantee of when repairs will be completed.
One livery service owner states that as soon as her 2023 Cadillac Escalade began exhibiting signs of lifter failure, she acted immediately to quickly source a new engine. Unfortunately, her efforts were in vain, as although she sought to address the issue weeks before the Escalade’s L87 was rendered inoperable, a replacement engine simply could not be found. Now, her vehicle has now been out of commission for weeks, costing her an estimated $30,000 in lost revenue, all with no clear resolution from GM.
GM dealerships are also facing the impact, with some resorting to hoarding replacement engines for high-priority customers, leaving others to fend for themselves. Social media posts indicate that dealers are now attempting in-house rebuilds as well, despite GM’s recommendation to avoid such practices.
For some customers, an entirely new vehicle is the only solution to keep their businesses operational, adding yet another financial burden to the mix. It’s unclear at this time when the NHTSA’s investigation may conclude.
NHTSA Probing Over 877,000 GM Trucks and SUVs Over Engine Failure
NHTSA Probing Over 877,000 GM Trucks and SUVs Over Engine Failure
FEBRUARY 2025 — MSN.com — The National Highway Traffic Safety Administration (NHTSA) has opened a preliminary probe into more than 877,000 trucks and SUVs built by General Motors. The agency’s Office of Defects Investigation (ODI) has received 39 complaints of engine failure due to a problem linked to faulty connecting rod bearings.
Launched in January 2025, the probe includes an estimated 877,710 vehicles powered by the 6.2-liter V-8 L87 engine. The following vehicles built from the 2019 to 2024 model years are under investigation:
Includes 877,710 vehicles: Here are the models involved
2019 to 2024 Chevrolet Silverado 1500 2019 to 2024 GMC Sierra 1500 2021 to 2024 Chevrolet Tahoe 2021 to 2024 Chevrolet Suburban 2021 to 2024 GMC Yukon 2021 to 2024 Cadillac Escalade (including the ESV model)
NHTSA documents describe one problem for all of these vehicles: at least one connecting rod bearing fails and either causes the engine to seize or results in a thrown rod. Owners of affected models who have experienced an engine failure told the NHTSA there’s no warning that the engine is about to fail.
“I was driving up a hill passing a semi at 60 mph. The engine suddenly stopped running without warning,” the owner of a 2022 Escalade wrote in a complaint sent to the NHTSA in June 2024. “The vehicle was towed to the dealer, and the next day I was told the engine had seized and would need to be replaced. The Escalade only had 25,000 miles on the odometer and I had purchased it new 2021,” the owner added.

Complainants reported a bearing failure that might result in either engine seizure or breaching of the engine block by the connecting rod.
February 2025 — CNN/Reuters — The National Highway Traffic Safety Administration said on Friday it was opening a preliminary probe into 877,710 vehicles manufactured by General Motors, after receiving reports alleging engine failure.
The investigation covers certain Chevrolet Silverado, GMC Sierra, Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon and Cadillac Escalade trucks and SUVs from model years 2019-2024, equipped with the L87 V8 engine.
According to the auto safety regulator, complainants reported a bearing failure that might result in either engine seizure or breaching of the engine block by the connecting rod.
Failure or malfunction of the engine could result in loss of motive power of the vehicle, leading to an increased risk of a crash. The NHTSA report, however, said no crashes or fires had been reported.
The auto safety regulator received 39 complaints and a number of early warning reporting field reports from vehicle owners, who also said there was no detectability prior to engine failures.
The probe, also known as a preliminary evaluation, was opened by NHTSA’s Office of Defects Investigation to determine the scope and severity of the potential problem and to fully assess the potential safety-related issues.
