Cadillac DeVille DTS Problems
Power Window Regulators May Fail and Cause the Window to Fall Into Door
One or more of the power window regulators (one in each door) may fail causing the window to fall into the door and not roll up.
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.
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.
Improper HVAC Temperature and/or Air Delivery Due to Failed Mode Door Actuator
One or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. If this occurs, fault code(s) should be stored in the HVAC control module which should assist in diagnoses.
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.

Cadillac DeVille DTS Stories
This is my third Cadillac and it will not be my last. Overall, the car has been very reliable and I still get compliments on it. I love the tight feel of the sport suspension (it does not have the tradionally soft and woosy ride of a Cadillac). The week spots are a little on the glaring side and are the same as my last Cadillac (a 2002 DeVille)--vent actuators, window regulators (I've had to replace all four windows), and A/C, heater blower motors (my last DeVille had the blower motor replaced five times).
Replaced 5 (twice on driver side) window regulators. Plastic parts on something used almost daily? Constant o2 codes. 80k miles. Drives great but too many repairs.
