We bought an Impala Chevrolet 2004 new in 2004. There were a few problems with it. Instrument panel cluster -and speedometer gauge did not work and noises came from the instrument panel. Steering gear popped/clanking noise heard and sensed from front end. Also, seemed like something was wrong with the transmission because it did not change gears correctly, and it kind of bumped when accelerating, appeared as if engine did not want to accelerate. There was a delayed start, may be necessary to hold key in start several seconds until starting or turning back and trying again. Sometimes key locked in and won't turn. Took to dealer, but it did not do it for them. On the steering gear the steering intermediate shaft was replaced on 11/19/05. Again the noise was back and on 07/17/07 the steering intermediate shaft was lubricated. On other issues repairs are to costly. Do not feel secure on vehicle these problems have been going on for the past two years.
