NHTSA Probes GM Engines After Owner Complaints Mount

The U.S. National Highway Traffic Safety Administration (NHTSA) initiated an investigation on January 19, 2026, concerning nearly 600,000 General Motors vehicles. This recall query targets GM's L87 6.2L V8 gas engines, which have been associated with significant engine damage and failure among owners.

The NHTSA's review was prompted by 36 Vehicle Owner Questionnaires detailing engine failures. Crucially, these complaints suggest that remedies provided under a previous recall may not have resolved the underlying issues, leading to renewed scrutiny.

This development revisits engine problems previously addressed by GM. In April 2025, the automaker recalled approximately 721,000 vehicles globally due to engine concerns, with a substantial portion, nearly 600,000, in the United States. The current query indicates ongoing concerns regarding engine reliability.
