18V437000 · Child Seat:Latch Strap | Seats:Mid/Rear Assembly
Reported: 2018-06-28 (June 28, 2018)
General Motors LLC (GM) is recalling certain 2016-2018 Cadillac CT6 vehicles. The inboard child seat anchorage bars may have had excess structural adhesive applied during assembly, which can interfere with the installation of a child seat. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 225, "Child Restraint Anchorage Systems."
Consequence: If the child seat cannot be attached correctly to the anchorage bar, there is an increased the risk of injury.
Remedy: GM will notify owners, and dealers will inspect, remove any excess adhesive, and apply anti-corrosion primer to the inboard child seat anchorage bars, free of charge. The recall began August 3, 2018. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is 18228.
