NHTSA Complaint #11573011 — 2011 BMW 328I

Tire pressure yellow warning light on. RDC module ordered but repair not completed. After starting the car at a gas station, multiple warning lights appeared in red including "car on a raised lift in red" which signifies car is to be taken directly for service. Drove to local mechanic one mile away. While observing the car with engine running at idle, ALL dashboard lights and functions stopped: No speedometer, No tachometer, No warning lights, No turn signals, No headlights, RDC module subsequently replaced with resolution of the problem. Opening the old RDC module demonstrated significant green corrosion - likely occurred over a long period of time. IF the loss of all dashboard function had occurred while driving, it would have presented very dangerous safety issues. Situation reviewed with local BMW dealership and BMW corporate customer relations. No recalls or warnings have been issued. Expressed my concerns in detail. This is a potentially dangerous problem for the BMW E90 models. The RDC module is located in the passenger rear wheel well and repeatedly exposed to wet/ snow/ slush conditions. This is a dangerous location outside the vehicle for the RDC module. The Tire pressure monitor system is a non-critical function. Repair of the RDC module is considered optional - yellow warning light. This event demonstrates that there is a serious risk when the RDC module is not functioning properly. BMW should make owners aware and offer replacement before dangerous events occur.
