I bought this car with 89000 miles on it. two weeks after it was bought the problems started. One day while driving, the battery light came and the car shut off. I replaced the battery (what the dealership told me was the ONLY problem). after the new battery it ran fine for about a month then it started again. The dealer told me nothing was wrong with it. Every time i turn on the a/c or heat the car will shut off, even when randomly driving it shuts off. The service tire monitor light came on, fixed that only for it to come back on shortly after. Love the car despite these issues but just wish the dealer would have helped more.

To anyone with a vibration issue. You need to keep the stock Michelin Symmetry's
on the car. Once I put new tires on and went to Sullivan Tire multiple times we did it. 0 to 100 MPH, no vibration.
Bad experience with Caddy dealer who had to be told to replace back seat control module twice. I wrote it in the P & S agreement the AC in the back didn't work.
1) Tire's (2) Dry boots and a broken axle
3) Broken engine front mount
4) Water pump froze and wiped out all the pully system. (5) Air intake sensor problem
6) Fuel pump float sending unit gone
7) 1-20-11 back in the shop for misfire and fuel
8) Replaced pass. window regulator

Overall it's been a fantastic machine. Very easy to drive,comfortable and smooth. Only thing that has broken three times were the window racks that hold the glass panels. Replaced under warranty but still, shouldn't be that fragile or poorly engineered. The gas mileage is unbelievable(18 city/26 hwy) for a car that size. This car will last me a long time and gives me great pleasure in owning and driving.
In an effort to improve its DeVille, Cadillac has made a few changes for 2003. On all models, the side-view mirrors are now fully equipped with turn-signal indicators, and all models also have revised taillamps. A tire-pressure monitoring system is also new. On the inside, base DeVilles can now get the navigation system as an option, and all models can be had with the XM Satellite Radio feature.
