2023 GMC Terrain recalls
NHTSA's recall file lists 2 safety recalls for the 2023 GMC Terrain, newest first.
Child seat: Vehicle latch anchor
NHTSA 23V339000Reported May 11, 2023
Filed by
General Motors, LLC (manufacturer recall no. N232403240)
Units affected
668,187 (estimate)
Problem
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.
Remedy
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.
Air bags: Sensor: Occupant classification: Front passenger
NHTSA 22V929000Reported Dec 15, 2022
Filed by
General Motors, LLC (manufacturer recall no. N222388911)
Units affected
9 (estimate)
Problem
General Motors, LLC (GM) is recalling certain 2023 Chevrolet Equinox and GMC Terrain vehicles equipped with ventilated front passenger seats. The Occupant Classification System may not properly disable the front passenger air bag when there is a small child or child restraint detected in the seat.
Risk
In the event of a crash, a front passenger air bag that deploys with a child or infant in the front passenger seat can increase their risk of injury.
Remedy
Dealers will replace the passenger presence system, free of charge. Owner notification letters were mailed January 24, 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 N222388911.
