The contact owns a 2004 Chevrolet Trailblazer. While driving 25 mph, the contact heard a rubbing noise coming from the front passenger side of the vehicle. She then noticed a burning odor coming from the engine. The vehicle was taken to a local repair shop and they determined that the oil cap for the four-wheel drive failed. The cap was replaced at the cost of $5 and the contact was advised to never place the vehicle into four-wheel drive. One year later, while driving at an unknown speed, the contact heard a humming noise coming from the front of the vehicle. She was able to safely drive the vehicle to her destination. The vehicle was taken to a local repair shop and the technician determined that the front differential failed. The repair would cost $2,000. The vehicle has not yet been repaired. The contact called the manufacturer and was informed that because the vehicle did not receive regular maintenance from a dealer, no compensation would be provided towards the repair. The VIN was unavailable. The failure mileage was 64,000 and current mileage was 81,000.

I own a 2004 Chevy Trailblazer with 56K mileage. In December 2008, the speedometer stopped working. I would be at stop, and the needle showed 80 mph. I brought the car to the dealership right away and they told me that the cluster needs to be replaced - but they needed to order the replacement part. I finally got it fixed a week later and it cost me approximately $525. Now, for the past two weeks, the engine had suddenly shut off in the middle of driving. The "reduced power" & "check engine" lights came on. Both times, it started back up after I parked it, turned off the ignition, and re-started. But after the second time, I brought it in to the dealership. I had to have the accelerator pedal replaced. Cost me approx $360. These two issues are very concerning with me because if I were driving at higher speed (65mph) in the middle of the highway (instead of 30mph around town), I could have died from contacts with other vehicles because my vehicles stopped functioning!

Purchased new Trailblazer in May 04. When vehicle had approximately 3,000 miles on it, I started getting a rattle or loud buzz when accelerating at approximately 25 per hours just before the vehicle shifts. Occasionally, the shift if jerky. The vehicle has to be warm and the rattle or buzz first manifested itself after I turned right and accelerated from a stop. When warm, this sound is repeated almost every time I turn right and accelerate. When warm is also occurs when I just accelerate from a full stop. Occasionally, it will also occur after a tight left turn. I reported it to the dealer and they told me the computer did not show anything wrong. On the second trip to the dealer I reported it again. Still no fix. The noise is very annoying, but I cannot tell that it is doing damage. I certainly would not have bought this vehicle if it made this noise on the road test. I am estimating the rattle or buzz sound has occurred at least 75 time to date.
