5/5 Overall
NHTSA 5-Star Safety Rating
The 2018 Cadillac XTS has 2 recalls, both concerning the rear brake system, where gas bubbles can form in the brake fluid and cause a soft pedal feel with reduced stopping power.
The root cause traces to the rear brake caliper pistons, which can develop gas pockets that work their way into the brake fluid. The result is a pedal that feels spongy underfoot and brakes that take longer to bring the vehicle to a stop, raising the risk of a collision.
