Complete brake failure while driving. No one was injured but the vehicle could not be stopped until the transmission went into limp mode with still no brakes. Now the ABS and SRS lights on. Brake pedal to the floor. I completely have new brakes speed sensors fluid exchanges and more. The current recall doesn’t seem to cover my vehicle. I contacted the dealership and they said there are no open recalls.
