Without the BRAKE lamp illuminating during the vehicle start up bulb-function check, the driver has no confirmation that the lamp is working and therefore may not know whether or not the lamp will illuminate if the brake fluid level is low.
The instrument cluster on the affected vehicles fails to illuminate the BRAKE warning lamp in the instrument cluster during the vehicle start up bulb-function check. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 105, "Hydraulic and Electric Brake Systems."
