Brake Light On problems of the 2005 Dodge Ram 3500

The abs control module on my 2005 Dodge Ram 3500 has failed. The failure was indicated by the barking brake light and abs light illuminating on the instrument panel, and the module motor continuing to run without applying the brakes. Turning the ignition off would not stop the module motor from running. My dealer does not have the module in stock and Chrysler corp is backordered on the item. The dealer's mechanic said he had personally seen 5 or 6 of these failures. My concern is that this is a safety item, and an integral part of the brakes. 1. ) if the module is allowed to run continuously there may be a fire danger, or possibly a further degradation of the braking system. 2. ) the abs braking system is rendered inoperative. 3. ) if the module is disconnected to stop the motor, other systems are affected such as the speedometer, and data systems displayed on the over head. 4. ) since Chrysler is back ordered on this safety item, this may indicate that there has been a rash of failures. The unit is manufactured by kelsey-hayes and has part numbers: p52121408ad tjzbk1984k0584 it also appears to be highly irresponsible on the part of Chrysler not to have this item readily available for replacement.
