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.
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.
No owner complaint on this car cites the child seat.
Power Train:Automatic Transmission

The start/stop accumulator endcap may have missing bolts.
Risk: Missing bolts on the start-stop accumulator endcap could result in a transmission oil leak and may progress to a loss of propulsion, increasing the risk of a crash. A transmission fluid leak in the presence of an ignition source may increase the risk of fire.
Remedy: GM will notify owners, and dealers will inspect the start-stop transmission accumulator and replace it if any bolts are missing, free of charge. The recall began December 15, 2020. Owners may contact GMC customer service at 1-888-988-7267, Buick Customer service at 1-866-608-8080, Chevrolet customer service at 1-800-222-1020 or Cadillac customer service at 1-800-458-8006.
