2004 Cadillac DeVille Reviews

I purchased a 2004 Cadillac DeVille. I will admit that the previous owner maintained this car according to the scheduled maintenance plan. It had all the records from the Cadillac dealer when I purchased it. The previous owner had it for 9 years. It was driven just over 14,500 miles per year. The car is like new. I just love it and the only complaint I would have is that the rotors heat up and warped so I am having a higher grade rotor put on. Great Car if maintained well. My gas mileage has been better than I hoped average of 21.5 in town. I don't know why others seem to complain you get what you buy. If you buy a used car check the records and know what you have purchased. It truly matters. I love my Cadillac DeVille.

Its a great car mechanically. But is has too many sensors and monitors that with time are going to malfunction. I have a 2004 cadillac deville. 190,000 miles. Im having trouble with old wiring and areas being monitored that still work but are old . Setting off codes like crazy and difficult to clear. I still get 19 miles city and 24 miles highway. Mechanically it rides great.im now changing a tps sensor connector. Im getting a code telling me insufficient voltage. Its off by .5volts and im going nuts with this .5 voltage problem. This is age not a problem with the cars running well.So its a pain in the arse so to speak later on. I didnt like changing the head gaskets with 50,000 miles on it. Very expensive etc.Electric switches on steering wheel lighted burn out, still work but they dont light. little bs things that shouldnt happen with this car.Not for the money u spend. If you still keep this car change the oil and filter every 3000 miles. let it drain well. it will run forever.

ILL FIX WHAT EVER I FREAKING LOVE THIS CAR plus every car will break down or another if it is not maintained or tuned. Ppl take good care of ur cars and they will take care of u

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.

Wow . . after reading all these negative reports I am so pleased to add mine to the positive ones [if there are any here]. We purchased our Deville new in late 2004. It currently has 184,000 miles on it. It's service to me has been incredible. Brakes once, torgue converter replaced once, a windshield wiper motor replaced. No other car I've owned in 50 years has given us better service with so little repairs. What else can I say?
