Wheel bearings busted at 25,000 miles.
Severe electrical problems: Half the dash does not light anymore, the power windows do not work properly (on a winter day, they will go down for no reason), the power locks do not work, replaced MAPS sensor twice (this sensor tells your car when it is out of gas; with a full tank, the car would die at high/low speeds thinking it was out of gas), and headlights/tail lights burn out every 6 months or so.
About once a month, it won't start in the morning.
The pin striping is pealing off on all sides of the car.
This car is not made for extensive driving; it does not handle normal wear and tear.
This is the first GM product I have ever owned and it will definitely be the last. None of the above listed were covered by any warranty. The dealership where the car was bought claim GM's have never had any electrical problems. I beg to differ.
Both times the MAPS sensors went out, I was 70 miles away from home. I was left stranded in the cold with a car that wouldn't start.
The inside of the car is very comfortable (traditional for Buicks), but being comfortable is the last thing to think about when you are stuck on the side of a busy highway with a broken car.
Handling and steering is very uneasy. When turning, the car is not agile or fluent in any manner.
Gas mileage was as expected; about 23 city and 27 highway (top average).
My last car, a Ford Taurus, lived for 296,000 miles. (actually, it was still running very well when I sold it) I think I will stick to Ford from now on.
