Print this page Notes: The 2002-2007 Chevrolet Trailblazer is known for many things, but perhaps it is most famous for its faulty fuel gauge.

This gauge flip-flops more than a politician during election season. Some report that the gauge says "empty" after a fill-up, while others report the gauge says "full" when they're running on fumes. Either way, there's one thing everyone seems to agree on: the darn thing is just wrong.

Following hundreds of complaints and a few accidents allegedly caused by the malfunction, the National Highway Traffic Safety Administration (NHTSA) opened an investigation into the issue in May 2011. Unfortunately for frustrated owners, no recall has been announced.

When the steering is turned too far the car automatically and very suddenly shuts off, no matter where we are. Seatbelts in the last row of the vehicle don't lock so, our car seats just slide due to never ending seat belt. Engine and oil light come on when car is started and will stay on for days as result of gas cap being not screwed on properly. Delayed turning reaction with steering wheel, horn got stuck and would not stop sounding so it had to be disabled.

The contact owns a 2005 Chevrolet Trailblazer. While driving approximately 45 mph, the vehicle failed to stop when the brakes were engaged. As a result, the vehicle crashed into another vehicle. The air bags failed to deploy. The contact mentioned that the rear seat belts that were restraining two children became unbuckled and ejected the children from their child safety seats.

Myself and my daughter was visiting my parents in Virginia and I turned the steering wheel to the right to go around a curve and the steering wheel didn't turn. I looked ay my daughter and said "oh _ _ _ _" and she ask me what 's wrong? I said the steering didn't turn and it wasn't but seconds later, we slammed into the side of the mountain on the driver side and we rolled two or three times and ended up on the roof. I immediately went unconscious because of the impact. I had a big gash on my head and was bleeding profusely and I was having trouble breathing because both of my lungs were punctured. All the windows burst out so my daughter was able to crawl out the passenger window to ask someone for help but my seat belt would not unbuckle so there was an issue getting me out. I was very lucky that someone that stopped had a pocket knife and cut the seatbelt to get me out. I had a bad concussion and I kept going in and out. I had three broken ribs, three pelvic fractures, a bad contusion on my elbow and I still have a swollen knot about two and a half inches on my left leg. I also have issues with my back and I am in constant pain and on impact, my seat belt jerked and caught my breast and I now have five cyst with the largest one being one inch and they are very painful. I have to watch it very closely because of a cancer risk called inflammation cancer. I was hospitalized for three days and I have to continue receiving medical care because of these injuries. My daughter is young and now she has back problems and ptsd and she also continues to receive medical care. This has really impacted and changed my life and my daughters life and I would really appreciate it if you would take the time to investigate these issues. We are going to have life long injuries and issues because of this accident. Thank you very much.

The contact owns a 2005 Chevrolet Trailblazer. The contact noticed a burning odor and smoke coming from the front passenger side door. The vehicle was taken to the dealer for diagnostics where the technician advised that the power window module was melted and would have to be replaced. There was an investigation under NHTSA action number: EA12004 (visibility:power window devices and controls electrical system) for the 2006-2007 models that could possibly have been related to the failure. The vehicle was not repaired. The contact also experienced a failure with the rear driver side seat belt. The passenger became trapped by the seat belt when it would not unlock. The contact had to cut the seat belt in order to release the passenger. The seat belt was repaired. The approximate failure mileage was 102,000.

The contact owns a 2005 Chevrolet Trailblazer. The contact stated that the driver side seat belt comes across the face and neck instead of her chest. The seat belt gets in the way when she is driving and is a safety hazard. In the event of a crash it will not protect her body instead it would injure her neck. The dealer was notified and there have been no diagnostic test performed. The vehicle identification number was not available. The failure and current mileages were unknown.

  • 40,000 miles
Hi there - I own a 2005 Chevy Trailblazer. At 40,000 miles, I had my truck serviced at the dealership with the complaint that my driver's seat belt locks as I try to put it on. At times, this has meant that I have had to drive without my seatbelt on because I simply cannot get it unlocked. I even purchased what the dealership termed to me as a bumper to bumper warranty - and they still have refused to fix the problem because it is intermittent and they have not been able to reproduce the problem! I see that the exact same problem was noted and recalled on 2002 Trailblazers - and from my experience, I think it is time to also include the 2005 Trailblazers on this recall as well.
