NHTSA Complaint #11701962 — 2017 CADILLAC ESCALADE ESV

2017 Cadillac Escalade ESV VIN: [XXX] Dealership: Jim Coleman Cadillac, Bethesda, MD I am reporting a brake safety failure involving severe and abnormal brake component wear that created an immediate safety risk with breaks completely failing while driving at high speed on the highway. During normal driving, I discovered that the right front brake assembly had worn down to bare metal. The brake pad friction material was completely gone, resulting in metal-on-metal contact with the rotor. The rotor showed deep scoring and unsafe wear consistent with a possible stuck caliper piston, seized caliper slide pins, or other component malfunction. This failure occurred without warning. The vehicle had been at the dealership for a customary inspection shortly before this issue, and the dealership did not report any brake wear concerns at that time. All brake services and major repairs on this vehicle have always been performed by the same Cadillac dealership. The last documented brake service with chanigng of the breaks involved was completed by the dealership in 2022. This is a critical safety issue that ]caused total brake failure. I am requesting that NHTSA review this defect, as premature brake destruction of this nature may indicate a systemic issue with the brake system, caliper operation, or inspection protocol on this model. The dealership was not sure of the reason why this happened that I was adviced that the bolt was missing and could have come off with vibration which is again a critical safety issue.
