2003 Chevrolet Trailblazer Owner Comments

problem #1

Aug 212007

Trailblazer 6-cyl Diesel

  • Automatic transmission
  • 110,000 miles


The contact owns a 2003 Chevrolet Trailblazer. While driving at an unknown speed, the engine warning light would sporadically illuminate on the instrument control panel. After injecting fuel into the vehicle, he would smell a strong odor of gasoline. He took the vehicle to a local mechanic and they stated that there was a leak. The fuel cap was replaced. Two weeks later, the engine light illuminated on the instrument control panel. He took the vehicle to the dealer and they stated that there was a fuel tank inject valve fracture, and that the manufacturer voluntarily recalled that component in August of 2007. The contact's VIN was not included; therefore, he would have to pay $1,200 for the repair. The manufacturer would not provide any assistance. The failure mileage was 110,000 and current mileage was 120,867.
