National Highway Traffic Safety Administration (NHTSA) opened a new safety probe on January 16th, 2025, looking into multiple General Motors brands that span five model years and a total of 877,710 potentially affected vehicles.

Owners of the vehicles complained of connecting rod bearing wear, which has led to catastrophic engine damage without any prior symptoms.

A recall of the affected models, which include the Chevrolet Silverado 1500 and GMC Sierra 1500, may be issued if needed.
