Cadillac DeVille Problems
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.
The engine may develop oil leaks 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.
One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.
The crankshaft position sensor may fail causing the engine to stall intermittently, the Check Engine Light may or may not illuminate.
The trunk pull down switch may fail causing the trunk lid not to close completely. Our technicians tell us that the failed switch can be replaced without changing the complete pull down motor assembly.

Cadillac DeVille Reviews
It is unfortunate that this car which my wife loves is such an maintenance nite-mare! Purchased in 2005 with 28K miles, now 8 years later and 107k miles, I have spent $12,200 in repairs, maintenance and tires. Do not purchase a 2000 - 2006 Deville as they are all ranked below average in reliability by Consumer Reports. Without a doubt the worst car decision I have ever made. The upside with this car is the great highway comfort, roomy back seat and the huge trunk that will carry all your stuff to Fl every year.
I just bought my Deville 2002 so far so good all these BAD reviews are worrying me, i had owned a 1997 and fan went out and blew head gasket with in a month of buying it used in 2012 soooooo I'm trying it again with this 2002 Deville. will update if any problems occure
Transmission problems are common and very expensive to fix. The price of a transmission replacement just about totals the car. AC system and PS pump have had to be replaced. No oil leaks, no engine failure thus far at 93k miles. Center console/body trim has several weak spots, specifically the center console is broken. Brakes get this big car to stop very well.
My 95 Cadillac Deville drives fairly well. Smooth on the road, luxurious and spacey interior and it just drives as steady as can be. I purchased this vehicle with a little over 60,000 miles on the odo, but it looks and feels like a brand new car. I am glad to have finally been able to afford one of these pure luxurious cars. I don't think I could ever buy anything else - I am now a happy Cadillac enthusiast. :)
My car does have the older 4.9l engine, with the real Cadillac name under the hood. If you speak about this engine you would refer to it as a 'Cadillac' engine. Probably the last engine purely made by GM's Cadillac division.
Tips on keeping away problems: 1) Always maintain your Cadillac; especially oil changes and other routine maintenance work. This would certainly save headaches later on. These older Cadillacs are very easy to maintain and do your own oil and filter changes. 2) Use the recommended 91 octane gas! This is required on 4.9l engines and later Northstar engines. Using a lower grade gas will shorten your engine's life and may cause severe engine damage in a very short period of time.
