Child seat: vehicle latch anchor

2023-05-11 · campaign 23V339000 · 668,187 vehicles

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 and remedy

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.

Seats and restraints

2023-05-11 · campaign 2023-279

Issue: The coating may be too thick on the connection bars for the lower universal anchorage system (UAS) for securing a child or booster seat in the rear seat. As a result, you may not be able to properly attach a child seat in the rear seat using the UAS. Safety Risk: A child seat that isn't properly attached could increase the risk of injury in a crash. Corrective Actions: General Motors will notify owners by mail and advise you to take your vehicle to a dealership to inspect the bars for the lower universal anchorage system (UAS) in the rear seat. If necessary, the dealer will remove and replace the finish coating on lower anchorage bars. General Motors recommends to install child seats using the rear seat belts, as described in the vehicle owner's manual and child-seat manufacturer's installation guide, until the recall repairs have been completed.

Powertrain

2020-10-29 · campaign 2020-520

Issue: On certain vehicles, the start-stop accumulator in the transmission may be missing bolts. As a result, transmission fluid could leak and eventually cause the transmission to stop working. If this happens, there could be a loss of power to the wheels. Safety Risk: A transmission fluid leak onto a hot surface can create the risk of a fire. Additionally, a loss of power to the wheels could increase the risk of a crash. Corrective Actions: General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to inspect the transmission start-stop accumulator. It will be replaced if any bolts are found missing.
