“Have been having major trouble with the front end. Had it checked multiple times at the dealer and at a local mechanics shop and the ball joints and bushings had to be replaced. Even the the warranty was finished, the dealer did not charge me for this, but unfortunately I thought that this would take care of the noise on the front end, but it is still there!! Also yesterday, april 24, 2007, I had to have the fan clutch replaced. This vehicle only has 35,000 miles. …”
NHTSA complaint #10188812, filed 2007-04, 10,000 miles“2002 chevy trailblazer service engine soon light will come on along with the reduced engine power light and the vehicle will not go faster than 40 MPH. Sometimes it will not go more than 20 and 10 MPH.

There was a recall on the control arms in 2001 that affected the 2002 chevy trailblazer. …”
