NHTSA complaint: 2021 CADILLAC CT5 — FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
When approaching a stopping vehicle the brake pedal became extremely hard to press and I could not brake enough to stop and had a collision. Come to find out that the ABS computer and the main ECU weren't communicating correctly which turned off the assisted braking, assisted steering and the AWD.
