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.

My son in law was driving the car with my permission and while making a left turn the vehicle stalled; there was no steering or brakes. The steering wheel locked up during the turn and caused the vehicle to continue turning on it's own and I proceeded to hit a pole. The radio and lights were still on during this time, however, the engine shut off.

Driving 40 mph in city traffic, approaching stopped traffic. Brakes start to lock up. While completely stopped the brakes are locked, the pedal will not compress. When apply gas, the car does not go forward. I had to put the car in park, turn off the car, and then start it and put back into drive for it to work.

I leased a 2007 Chevy Trailblazer on May 31st 2007 at wally edgar dealership. When the weather started turning below 50degrees the brakes started to fail. We took it into wally edgar dealership in January 2008. All they did was bleed the brakes. Within 2 months the brakes were back to failing. I took it in to lunghumer dealership in April 2008, this time they replaced the master cylinder. That worked for awhile.. well within a month I was back at wally edgar dropping it off because the brake pedal had exceeded the last two times it was within 1/2 inch of the floor. This time they bleed the brakes and claimed the problem was an air bubble in a caliper. Well everything was going okay until the first real cold of the year. My brakes were down to the floor literally. I was unsure if they were going to stop me. This time they did their job at wally edgar and replaced a modular sensor. The brakes seemed to be working good. That was January 14, 2009. Within a week the 4WD service light came on. The transfercase switch was replaced. January 22, 2009. Then on January 30th my service brake light and stabilitrak light came on. Since they couldn't figure out what was wrong they decided to replace the calipers, master cylinder, and electric brake module. And I am suppose to feel safe in this heap of junk.
