CarComplaints.com 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.

problem #2

Trailblazer LT 6 cyl

Have had the air pump and valve replaced twice. The light is back on again. The transmission went out 85 miles from a G M dealer in Missouri and had to be rebuilt. Both the heated seat bottoms quit working. Ball joints had to be replaced because there is no way to grease them. The problems the engineers have put into this vehicle have gotten worse instead of better after being built for several years. This is the second GM car I had, the other being a Cadillac that were expensive to maintain. I have been driving G M cars and trucks from 1952 and was used to the quality that was built into them. Time to change companies.

problem #1

Trailblazer LS 3.2L V6

  • Automatic transmission
  • 60,000 miles

The air flow intake compressor or whatever it is called went out and was sitting in a puddle of water. The part had to be replaced. The service tech asked if I went through a river. I said NO! and that is not called for. I was furious! Now one year later, same problem! Not only do I have a lemon but the dealer is awful (Gus Paulos)
