I bought the car from a friend. In the past couple of years, the car has blown out 9 air conditioning pumps (current one is blown) $425.00. Goes through front disk brakes very quickly. (usually still under warranty.) Rear door panel is falling off. Passenger power-seat motors are going out, they make a horrible grinding noise when adjusting. The rear shocks are still relatively new, but the car still sags. Motor Mounts have been changed four or five times in the past year. The twilight sentinel is temperamental, and seems to work when it wants. The fuel information system often displays incorrect readings. The "auto-dim" mirror has stopped working and is unknown as to why. (no way to fix it.) Outside key holes on both doors are acting up; they try to eat your key. (Driver's side stopped working completely.) Needs an oil change every two thousand miles. (if you go 3000mi. a rod will start to knock.) The front disk brakes squeak no matter what efforts are made to fix it. "Service Soon" light turns on while driving, no mechanical defects, the "Engine Coolant" lid fails to stay latched. Transmission needed to be replaced around 150,000. $500.00.
Despite all of the problems, I love this car, and I plan to keep it until it dies.
Runs strong when tuned. Gets very good gas mileage on the highway. (considering its weight and large engine.)
Interior could use some work, large tear in driver's seat (covered when you're driving.) The rear seats are still in "brand new" condition. The heater (only climate control feature that works) will roast you in only a matter of minutes.
I love all of the comfort and convenience features. The trunk especially. The only car I've owned that it pops all the way up, and closes by it's self. Auto headlights, a must for any teen that is on-the-go.
Basically, besides all of the minor problems, for only having the car about a month, I love it!
Gas is just on the pricey side though. In Utah, where gas is 2.20 for mid-grade, can't afford to fill it up all the time. Just a helpful hint to fellow DE Ville owners, with 2 gallons (fuel information center data) you have about a mile to find a service station.
