- CHILD SEATNHTSA 23V339000May 11, 2023
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."
Consequence: 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.

Reliability verdict for the 2021 GMC Terrain
With a 78/100 reliability score against a 72/100 segment average, the 2021 GMC Terrain rates above average. The data points to generally solid dependability rather than standout strength, but it lands on the favorable side of the segment. As year four of the current generation, it reflects a model that’s not in its earliest cycle.
Complaints are not dominated by a single system. They cluster most around the powertrain and electrical system, with smaller shares spread across brakes, engine, and miscellaneous reports. That distribution suggests a mix of issue types instead of one persistent fault pattern. Recall activity is limited, which helps keep overall exposure controlled.
Overall, the Terrain presents a moderate-to-low reliability risk for buyers.
