18V437000

Date: 2018-06-28. Systems: CHILD SEAT, SEATS.

Defect: 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.

Do not drive: No. Park outside: No.

Notes on this record

  • Complaints from the API and bulk file are merged and deduplicated by ODI number; the API alone misses records.
  • System and subsystem counts are numbers of distinct complaints, recalls or communications that name them. One record can name several systems, so shares across systems can add to more than 100 percent; a single share never exceeds 100 percent.
  • Recalls are counted once per campaign, investigations once per action and manufacturer communications once per NHTSA id, even when NHTSA lists several model names for the same record.
  • A sales denominator is a calendar-year proxy, not the population of vehicles still in use. Rates are copied from verified pipeline output.
