problem #10

Oct 312015

Trailblazer LS

  • Automatic transmission
  • 58,000 miles

Lights flicker and dim when you touch the brakes or let off the gas. People probably think I'm flashing my lights at them. It's very aggravating at a minimum, and potentially dangerous.

Trailblazer LX 3.2L V6

  • Automatic transmission

The door constantly locks me out of the vehicle......taken to garage approx 14 times ....never fixed. Head lights constantly flicker and dim while driving. Taken to GM 15 times still not fixed. GM rep was brought in to evaluate problem.....He took it out for a test ride ....got out of the vehicle and he too was locked out!!! 10 years later and the same problem continues!!!!!!!

Trailblazer LS V6

  • Automatic transmission
  • 70,000 miles

Again another UNSAFE event. The truck wants to stall sometimes on take off and when I drive and take my foot off the gas petal, the headlights and dash lights flicker!!!! You would think with all the electrical issues going on with this year and model vehicle they would do something about it!!!!!!!!

problem #4

Mar 092009

Trailblazer LS 4.2L V6

  • Automatic transmission
  • 79,000 miles

On occasions, my lights would get bright then dim after about a second or two. I thought it was just a loose wire or something. After seeing more post about this, I am not the only one again. This model has so many issues. Can I get my money back? I cant refer people to buy American after all these issues with this car. I checked the amount of Chevrolet recalls and its amazing that they would release so many defective cars. I would be putting my friends and family in danger.

I cant tell how fast I'm driving or tell whether I have enough gas to get to my destination and sweating like crazy to get somewhere due to my Blower Motor Resistor problem. This all happened about the same time right after the warranty expired. Is there any help out there? I cant even take my kids out when it gets really hot (like now).

Fix my problem Chevy! I hope someone from Chevy is reading this. This is a very serious problem and someone will bound to get hurt by this car. Please recall it!

problem #3

Jun 282005

Trailblazer LT 4.2L I6

  • Automatic transmission
  • 100 miles

The headlights and dash lights flicker, but not every time I drive at night. When it does happen, it drives me nuts and wonder if the local cops will stop me for something as stupid as this. They stopped me for forgetting to turn off my high beams one time. Asked me if I had been drinking because drunk drivers often forget to turn off high beams or forget to turn their lights on altogether. I hadn't been drinking, but I do have a couple of beers when I bowl with my wife in a mixed league with her family. Every time, I hope that the lights don't play their little dance and draw undue attention. I'm out of warranty and probably won't hear from GM on the issue, unless I call the dealer where I bought it, I'll never know if the problem is resolved. Now that they're all asking for money to bail them out, maybe they will find a little extra cash to develop a repair to take care of this pain in the ass problem that some of us share......

Trailblazer LS 6

  • Automatic transmission
  • 50,000 miles

Many,many,many owners complain of the headlight flickering to a point they seem to turn off for an instant while driving. This I also found to be true of my Trailblazer. Does this not concern Chevrolet? Do you wish for someone to have an accident. It may have happened or may soon to happen.

Trailblazer LS

  • Automatic transmission

Headlights flicker all the time!!!! Low beams only. I had it to the dealer and once again they say that this is normal!!! I've had other cars, even GM, and none have done this!
