Quick Takeaways
- General Motors engine failure probe raises safety concerns for nearly 600,000 vehicles
- NHTSA investigation focuses on V8-powered GM pickups and SUVs from 2019–2024
On January 16, the U.S. National Highway Transportation Safety Administration (NHTSA) initiated a safety probe into General Motors over concerns that 597,571 full-size pickup trucks and sport utility vehicles could be exposed to potential engine failure. The General Motors engine failure probe centers on reports indicating sudden loss of power without prior warning.
Vehicles covered under the General Motors engine failure probe
The preliminary evaluation targets V8-equipped models sold under multiple GM brands. According to NHTSA, the affected vehicles include Chevrolet Silverado and GMC Sierra pickup trucks, along with Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, and Cadillac Escalade SUVs manufactured between model years 2019 and 2024.
These vehicles are widely used for both personal and commercial purposes, making the scope of the investigation particularly significant within the automotive market.
Reported engine failure risks and safety concerns
NHTSA stated in documents published on its website that an engine failure could result in a sudden loss of vehicle propulsion, which may increase the risk of a crash. The agency has received 39 consumer complaints related to bearing failures that could lead to engine seizure or a connecting rod puncturing the engine block.
Investigators noted that there are no visible warning signs or alerts before the failure occurs, limiting a driver’s ability to take preventive action before power loss.
Link to earlier recall and adequacy of the remedy
The General Motors engine failure probe follows an earlier recall, identified as 25V-274, involving vehicles equipped with the L87 6.2-liter V8 gasoline engine that experienced engine damage or failure. That recall remedy included engine inspections, an oil change using higher-viscosity oil, or complete engine replacement where required.
NHTSA’s Office of Defects Investigation has launched this new evaluation to assess whether the corrective measures implemented under Recall 25V-274 were sufficient to address the underlying safety risk across the affected vehicle population.
