Washington, D.C. – January 31, 2025 – The U.S. government auto safety regulator is investigating General Motors (NYSE:GM), which owns the Cadillac, Chevrolet, and GMC brands, over allegations of its vehicles stalling due to engine failure.
The investigation could lead to a recall of 877,710 SUVs and pickup trucks.
The following vehicles would be affected:
- 2021 Cadillac Escalade NA
- 2024 Chevrolet Suburban
- 2021 – 2024 Cadillac Escalade
- 2021 – 2024 Cadillac Escalade ESV
- 2019 – 2024 Chevrolet Silverado 1500
- 2021 – 2022 Chevrolet Suburban
- 2021 – 2024 Chevrolet Tahoe
- 2019 – 2024 GMC Sierra 1500
- 2021 – 2024 GMC Yukon
- 2021 – 2024 GMC Yukon XL
All cars have the L87 6.2-liter V8 engine.
Investigation summary
The regulator, the National Highway Traffic Safety Administration (NHTSA), opened a preliminary investigation on January 16, 2025, following 39 complaints and numerous reports of vehicles that would stall while driving.
According to the initial findings, this happens because of a connecting rod bearing failure. This can cause the engine to seize or result in the bearing piercing the engine block.
The investigation aims to discover how widespread this problem may be and the impact it may have on road safety.
Risks
A seized engine will stall the vehicle, increasing the risk of a crash and injury. Bearings that pierce the engine have been the cause of engine fires in other, similar recalls but it is not clear if that is a possibility in this particular investigation.
Other Chevrolet recalls
In December 2024, GM expanded its previous recall caused by tailgates that would open on their own, as reported.
In January 2025, Chevrolet electric SUVs were recalled over malfunctioning pedestrian warning systems, also as reported.
