Cadillac DeVille DTS Problems

Service Stability Message Due to Failed Steering Wheel Position Sensor

The steering wheel position sensor may fail, resulting in the service stability message being displayed.

Oil Leak From Lower Engine Area

The engine may develop an oil leak from the lower crankcase portion of the engine block. Our technicians tell us that the engine must be removed from the vehicle to properly repair this oil leak.

Coolant Leaks From Water Pump and Radiator

The water pump and/or the plastic side tanks on the radiator may leak causing a loss of coolant. The engine may overheat due to coolant loss. Continued coolant loss after external leaks have been repaired could indicate a blown head gasket.
