Campaign #21V612000 05/08/2021
TIRES

General Motors, LLC (GM) is recalling certain 2021-2022 Chevrolet Equinox and GMC Terrain vehicles equipped with certain Hankook tires. The tires may have been manufactured with an insufficient amount of curative agent, which could cause tread separation.

Risk: Tread separation can result in a loss of vehicle control, increasing the risk of a crash.

Fix: Dealers will inspect the tire DOT numbers, and replace any affected tires, free of charge. Owner notification letters were mailed on August 31, 2021. Owners may contact GMC customer service at 1-800-462-8782; and Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N212343560.

Campaign #23V339000 11/05/2023
CHILD SEAT:VEHICLE LATCH ANCHOR

General Motors, LLC (GM) is recalling certain 2020-2023 Chevrolet Equinox and GMC Terrain vehicles. The four rear-seat lower child seat LATCH anchorage bars may have excessive powder coating, which could prevent a child seat from being installed with the anchorage bars. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 225, "Child Restraint Anchorage Systems."

Risk: The inability to install a child seat with the LATCH anchorage bars could result in an unsecured child seat, increasing the risk of injury in a crash.

Fix: Owners are advised to install child seats using the vehicle's rear seat belts until the remedy is complete. Dealers will inspect the latch anchorage bars, and remove and replace the finish, as necessary, free of charge. Owner notification letters were mailed June 2, 2023. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is N232403240.
