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.

problem #4

Trailblazer LS 4.2L V6

  • Automatic transmission
  • 101,000 miles


Bought my 07 Trailblazer used in November 2011. In August 2012 I had to replace the lines, bought them myself and did it to save money. It hasn't even been 3 years and they need replaced again. They busted while I was driving and I'm lucky I did no damage.

Trailblazer LS V6

  • Automatic transmission
  • 56,545 miles

Engine light is on. Took it to the dealer and it will cost $500 to fix it. I am really tired of my truck. I have had a lot of problems with my 2007 Trailblazer. I bought it brand new with only 10 miles on it. I keep up with my maintenance and oil changes as well. This is problem #4 with this vehicle!!!

problem #1

  • Automatic transmission
  • 48,000 miles

The transmission lines rotted off. I've never had anything like this happen to any of my vehicles. This one was only 2 years old at the time. I have had vehicles with over 200,000 miles rusted to pieces and this has not happened. This was not covered under warranty either, the garage said that the lines were not part of the powertrain. I could have lost my transmission if I hadn't noticed a sheen in the water after it rained.
