The 2019 Cadillac XTS has 3 recalls, the most serious being a front seat belt buckle that can separate from its mounting strap in a crash, leaving the occupant without effective restraint.
The seat belt issue stems from a missing rivet that is meant to secure the buckle head to the cable mounting strap. Without it, the buckle can pull free in a collision rather than holding the occupant in place. The third recall also concerns the brakes: the rear brake caliper pistons may have developed gas pockets beneath their coating, which can reduce the clamping force the rear brakes generate. In practical terms, this means the vehicle may take longer to stop than expected, raising the risk of a crash.
