What's wrong?
The front passenger seat belt webbing on the 2016 Cadillac CT6 is the woven strap that holds the passenger against the seat during a stop or crash. A bolt fastens that webbing to the seat's anchor plate, so the belt stays connected when it is loaded. That connection is part of how the restraint system keeps the passenger in position.
On affected CT6 vehicles, the assembly plant failed to insert and secure that bolt during work in the seat belt assembly area. Without the bolt, the webbing is not locked to the seat anchor. When force is placed on the belt, the strap can detach instead of holding the passenger as designed.
There is no warning sign before failure. The belt can look normal until it is pulled hard or needed in a crash, so the issue depends on the dealer inspection and repair.

What happens at the repair
At the dealer, a Cadillac technician replaces the existing front passenger seat belt webbing anchor bolt, or installs the bolt if it is missing. Parts and labor are free under the recall. Until the work is done, do not let anyone sit in the front passenger seat. Out-of-pocket repairs already paid are handled through the existing warranty, not through a separate reimbursement program, because the covered vehicles are under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
