Heard a popping sound near the center front of the SUV. Thereafter noticed some grinding going on when the SUV was accelerating. Took it a dealer to have look at the brakes. Turned out to be the front axle assembly broke and got metal filings in the differential causing the transmission to slip. Repair cost thirty-three hundred dollars. Replaced the differential and front axle assembly.

2003 trailblazer - reduced engine power light present when started. Would accelerate to 15mph. Rattle or grinding noise when braking or driving over bumps. Drove to beaty chevrolet knoxville tn tues, 2/7/06. Replaced throttle assembly & advised noise was from misaligned hood. Trailblazer picked up on fri, 2/10/06. Paid $200. Ext warranty ded. Gas empty stopped to fill up. While driving noticed fuel gauge past full mark, appeared to be pointing straight down. Noticed tachometer registered 6500 rpms. Called beaty chevrolet. Service department closed. Next day fuel gauge appears correct. After a week refueled and noticed fuel gauge was incorrect again. Noticed strong gas odor when vehicle is started & vehicle smoking. Called to schedule repairs on 2/28/06. Was unable to make appointment rescheduled for tues 3/9/06. Beaty informed that it must be guage sensor and not related to previous repair work so another $200. Deductible would be due. They were unable to detect fuel odor nor smoking. I disagreed with the $200 charge due to vehicle being defective when I picked it up from the service department on the first visit. Beaty chev. Said they did not look at the tachometer nor fuel gauge when they service vehicles so they would not have known about the problem. Lol .. I called gm warranty and they would not waive the $200 and said the dealership would be responsible. I contacted the dealership again and they thought gm would waived because of the numerous problems with the guage sensors. However they would not admit that they did not check the vehicle when it was being repaired the first visit. I have read numerous complaints regarding reduced power throttle assembly, guage malfunctions, and grinding noise when braking and feel that gm should recall and reimburse the consumer for the repairs they have paid. Vehicle is still making grinding noise and now seems to lunge forward when brake is released. I need help and any advice you have to offer.

The transmission on my 2003 trailblazer stopped working while driving out of my driveway and onto the highway. All gears including neutral grind gears when engaged. The car could not be driven and needed to be towed to the transmission shop. This cas has never been towed or plowed and rarely uses 4 wheel drive (winters only). It now has 39k miles and out of warranty, however, I now realize that there has been many transmission problems like mine in earlier year models as well as the 2003. I would like this organization to investigate the possible flaw in gm's transmission used in these vehicles. Thank you.

While putting the trailblazer into any gear it makes grinding noise in rear. While driving to the dealer the rear of the blazer was all over the road. It felt like the rear wheels where going to fall off. While still many miles away from dealer for service the back axial locked up making me loose control. This was at 25 MPH. Thank goodness I did not take the highway. I dont want to know what would have happened at 65 MPH. I had to have towed to dealer from there. I was told that a bearing breaking caused this. However first I was accused of having the vehicle 4 wheeling.
