Traffic ahead of me rapidly decelerated. Upon applying the brakes, the peddle froze and then went to the floor without any resistance. I attempted to pump the brakes without success. I impacted the car ahead of me at 40 mph, the posted speed limit, creating substantial damage to both vehicles. The brakes failed to operate and the airbags failed to deploy upon impact. The vehicle failed to slow down and was reacting as if the accelerator was stuck. There were no system warnings at the time of the accident or afterwards. Braking abilities resumed immediately after impact. There is no visible evidence of any fluid leaks, brake fluid or otherwise. The vehicle was last serviced by the dealership for an oil change at the end of January 2024. A brake inspection was performed at that time. I was aware of a recall notice Campaign 251 regarding the brake ABS system. When I inquired at the last service date, I was informed no fix was available at that time. Current mileage is 49,779. I am still in the process of locating a repair shop.
