What's wrong?
The inboard child seat anchorage bars in the rear seating area of the 2016-2018 Cadillac CT6 and CT6 Plug-In Hybrid are the metal bars used by a child seat's LATCH connectors. When they are clear and the right size, the child seat connector can lock onto the bar and hold the seat in place as designed. The system depends on the bar being reachable and free of extra material.
On affected vehicles, structural body adhesive transferred onto one or both inboard anchorage bars while a body panel was lowered into place during assembly. After the adhesive hardened, it left extra material on the bar. That buildup can make the bar too large in spots or block the connector path, which can interfere with installing a child seat and does not meet the federal child-restraint anchorage standard.
The warning sign is visible or practical during child-seat installation. You can see small amounts of hardened adhesive on the inboard anchorage bar, or the child seat connector does not attach to the bar correctly.

What's the safety risk?
A child seat that cannot attach correctly to the anchorage bar increases the risk of injury. While installing the seat, you can notice that the anchorage bar cannot be used or see hardened adhesive on the inboard anchorage bar. If the anchor is blocked, stop that installation and schedule the dealer inspection. Repair is free at any franchised Cadillac dealer.

At the dealer, a Cadillac technician inspects the inboard child seat anchorage bars, removes any excess structural adhesive, and applies anti corrosion primer to the bars. The recall repair is free, with parts and labor covered by Cadillac. Prior related repairs are handled through warranty coverage, not a separate reimbursement program, because all covered vehicles are under warranty.
