General Motors has issued a large-scale recall involving nearly 600,000 vehicles across its Cadillac, Chevrolet and GMC brands. The recall, announced in late April 2025, addresses a potentially dangerous engine defect tied to the 6.2-liter V8 engines installed in a wide range of popular SUVs and trucks.

The National Highway Traffic Safety Administration has confirmed the recall spans 32 different models manufactured between 2021 and 2024. Notable affected models include the Cadillac Escalade, Chevrolet Tahoe and GMC Yukon. All vehicles involved are equipped with the 6.2L V8 gas engine, a cornerstone powertrain in GM’s large vehicle lineup.

Details of the engine defect

The defect stems from flaws in the engine’s connecting rod and crankshaft components, which could result in sudden engine failure. The issue was traced back to manufacturing inconsistencies at a supplier facility, leading to the improper formation of key internal engine parts.

According to documents filed with the National Highway Traffic Safety Administration, these engine components may fracture while the vehicle is in motion. Early warning signs include knocking sounds, illumination of the check engine light and sudden loss of propulsion. While no injuries or crashes have been linked to the issue as of publication, the severity of the defect necessitated immediate action from GM.

GM’s response and repair process

In response, GM has committed to a full-scale inspection and repair program at no cost to vehicle owners. Dealerships will begin offering diagnostic tests to identify affected engines and, if necessary, will replace defective parts or entire engines using updated components.

Notification letters are scheduled to be sent by June 9, 2025. GM is advising affected customers to contact their local dealer and avoid extended driving if any unusual symptoms arise.

The company noted that vehicles already showing engine symptoms will receive priority servicing. GM will also provide courtesy transportation for customers whose repairs require extended downtime.

Impact on consumers and the automotive industry

For consumers, this recall introduces safety and reliability concerns for vehicles often relied upon for family and commercial transport. The Cadillac Escalade, Chevrolet Suburban and GMC Sierra are among the highest-selling large vehicles in North America, and this recall affects core segments of GM’s customer base.

Industry analysts suggest that GM’s response to the defect will be closely watched by regulators and customers alike. The recall comes at a time when automakers are under increasing pressure to maintain stringent quality control, particularly on high-performance engines.

For GM, this marks one of the largest engine-related recalls in recent years. The company has previously managed recalls due to brake issues and seat belt failures, but this defect directly impacts vehicle drivability, which is a more sensitive issue for buyers.

Regulatory oversight and future implications

The National Highway Traffic Safety Administration continues to monitor GM’s investigation and remediation process. As part of its standard protocol, the agency may request further technical details on manufacturing changes and will ensure that all customer notifications meet regulatory standards.

This case may lead to broader discussions about engine manufacturing standards and post-pandemic supply chain practices. With growing reliance on outsourced components, automakers continue to face complex challenges in verifying supplier quality.
