The hazard
On certain vehicles equipped with an MBE900 (EPA04 and EPA07) engine, the intake air grid heater may short circuit and fail. This could result in a vehicle fire causing property damage and/or personal injury. Correction: Dealers will install an additional external relay to prevent battery connection to the grid heater when the vehicle is not running and when grid heater control signal is absent.
