2003 Chevrolet Trailblazer EXT Owner Comments

Trailblazer EXT 4WD 6-cyl

  • Automatic transmission
  • 49,000 miles


We purchased our 2003 Trailblazer ext used this summer. It had about 50,000 miles on it. We've noticed that when we're on the road for over 2 hours at a time, the speedometer becomes dangerously unreliable. Most recently, my husband was pulled over for an unsafe low speed -- until the state policeman saw that the speedometer was registering 20 miles an hour with the car in park and the engine turned off. We have had multiple failures. Resetting is sometimes possible by continually restarting the car, but not always, and not with any reliability. By continually restarting I'm talking 30-50 restarts. The wear and tear on the starter therefore is unacceptable. This vehicle should be covered by the recall, but we've not been notified and when we've taken it to dealerships, we haven't even been notified of the recall. The problem has no other discernible pattern and has happened approximately 6 times in the 8 months we've had the car.
