Mercedes has announced that they will be recalling certain models of the 2008 Mercedes Benz R. They stated that on certain passenger vehicles equipped with diesel engines, the crankshaft sensors could fail due to separation of bond wires from the lead frame in the sensor. This results in a interruption in the electrical connection in the chip housing of the sensor.
When this happens, the vehicle may loose power rather than enter a limp home mode. In addition, the vehicle cannot be restarted after failure of the electrical connection in the sensor, increasing the risk of a crash. Dealers will replace the crankshaft sensor. Owners may contact Mercedes Benz at 1-800-367-6372.
