Overall I enjoyed my car when I first bought it in 2008. I have had to take my car in four times in the last three months. Things that have gone wrong in the last 2 years: replace door locks (driver side front and back), keyless remotes, exhaust and cam solenoids, emergency brake, tires, brakes, OnStar system, Intermediate shaft in steering column, and numerous sensors. I am happy that I bought the extended warranty. I recently have had to put new brakes on the car and new tires. The car only has 55,500 miles on it. Will never own another GM product.
The extended warranty, OnStar system, design of the interior.
