Oct 2, 2024
General Motors, LLC (GM) is recalling certain 2025 Chevrolet Blazer, Blazer EV, and Equinox vehicles. The door strikers were not properly heat-treated, which can cause them to break.
Consequence & remedy
Consequence: A broken door striker can cause the door to open unexpectedly, increasing the risk of injury.
Remedy: Dealers will replace all four side door strikers and attachment bolts, free of charge. All affected vehicles are still in dealership inventory and therefore no owner notification letters are expected to be mailed. Owners may call Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N242477131.
