problem #26

May 242014

Trailblazer 8-cyl

  • 27,225 miles


On the 2008 Trailblazer, had two problems with the ignition switch. In April 2011 the tumbler mechanism portion of the ignition switch failed at approximately 27,225 miles and was replace under warranty. In May 2014 had difficulty starting the vehicle when the ignition switch was in the start position. Was able to start the vehicle and drive to the Chevrolet dealership. While waiting for the service technician, I moved the tilt steering wheel to a different position and the vehicle stopped running. This would have been an extremely dangerous situation under normal driving conditions. It was diagnosed that the electrical portion of the ignition switch had failed. The ignition switch was replaced. The approximate mileage was 71878.

Trailblazer 6-cyl

  • 69,000 miles


Repeated issue. Smell of smoke/burning triggers dash warning signals. Same dash warning signals come on without smell of smoke/burning. Cycle repeats itself without pattern, and includes during 4 wheel use. Vehicle taken to multiple Chevrolet dealerships for service (Utah, North Carolina and Washington) with the dash warning lights on. Utah and nc claim unable to replicate event or identify problem, so listed as unknown without correction. GMC executive office interdiction resulted in replacement of stereo even though dash light indicate powertrain & electrical. Stereo broke 2 mos later. Gmeo and wa identified fuse issue related to 4 wheel drive, but unable to replicate smoke/burning before claiming issue resolved. Dash warning lights constantly come on and off indicating problem with powertrain/electrical. Gmeo closed case as resolved.

  • 98,000 miles


I've noticed several times that my vehicle will turn on when I place the ignition key into the "on" position right before I turn the key all the way to start it. I'm not sure if it was due to the cold weather or not. Also, my engine light is always on and I had it tested which came back as an emissions control problem. Which could be the gas cap I haven't paid to fix yet.

Trailblazer 6-cyl

  • 90,000 miles
In the fall of 2012, I had to replace an ignition switch in my Trailblazer at approx. 90,000 miles. Then, in July of 2013, we were driving on interstate 95 in ct, heavy traffic, high speeds, and all of a sudden my car just died. I, fortunately, was in the right hand lane and was able to drift off the road. A ct trooper sat behind us for an hour while we waited for aaa. It was a Sunday. We were towed to a Chevrolet dealer in old saysbrook, essex ct. Had to spend the night in a hotel and that Monday, the dealer put in another ignition switch. My mileage was a little over 100,000. Have all the documentation. Have you looked into ignition switch failure in Trailblazers" is my car safe to drive" would appreciate a response.

I had to replace the driver side window motor at about 30,000 miles and now the passenger side motor is acting up and will probably have to be replaced - I am currently at 38000 miles. Seeing so many other complaints, including vehicle door fires, this should be recalled.

Trailblazer 6-cyl

  • 70,000 miles


Incident with my 2008 Chevy Trailblazer incident reported on Sept. 9 at 9:30pm which occurred as I was driving home from a cubscouts meeting, with my 2 sons in the vehicle. As I was driving home around 845pm home from our methodist church, which is located about.3 mile from my house. The lights on the dashboard and the headlights were not working all of a sudden and I could smell something burning as I a driving. The time of the day was dusk and starting to get dark but a clear sunny day before this occurred. My oldest son, who is 9, said what is that smell and then my other son, who is 4 years old also said the same thing. I drove slowly down the hill as this occurred off the road and the red light near our subdivision entrance. I live in hixson tn. I also noticed there was black smoke coming from under the hood area near the fuse box area on the drivers side vehicle. I got home within 5 minutes of this happening and immediately pulled my car into my drive way and told both my boys to get out of the car. I pulled the hood release under the steering wheel and went to lift the hood and could see black smoke was coming from the fuse box area. I popped the end clips that keeps the fuse box in place and opened the fuse box. When I did this, there was a spark of flame and smoke that put itself out when I lifted the lid off the fuse box and you can see what happened(photo attached for you to see). You can see there is significant damage to many fuses that control the electronics in the vehicle. I have not driven this vehicle since this occurred as the person I talked to instructed me not to move the vehicle. I would hate to get legal counsel involved and the national safety and transportation commission involved and would hope Chevy would like to get this resolved.

Trailblazer 6-cyl

  • 93,000 miles
Water got on the window switches because the drivers window was left open a little during a rain storm, and none of the windows or door lock switches on the drivers door worked for 2 days. I know that there's a re-call for 2006 & 2007 model years for the same reason, so why not on the 2008?

Trailblazer 6-cyl

  • 115,600 miles
Driver door lost power not working at all, all other functions (passenger, rear, and trunk locking functions work) there was a recall on this same function for 2006-2007 but 2008 was not include. The corrosion that could result in a short in the circuit board. A power short in door lock and power window switches to function intermittently or become inoperative. The short cause overhearing, which could melt components of the door module, producing odor, smoke, or a fire. After review with my service provider this is same problem with the pass recall. Chevrolet recall does not go far enough to include all model year's after 2007 which also be checked for older parts place in newer models.

Trailblazer 6-cyl

  • 47,200 miles
Electrical power distribution box power wiring/ribbon that is under left rear seat overheated and caught papers inside car on fire and caught entire car on fire from overheated copper ribbon that failed to trip circuit breaker to stop wiring ribbon overheating. This defect is common and when the manufacturer changed from wires to copper ribbon foil it created a means for wiring/ribbon overheating and source of fire to begin.

Trailblazer 6-cyl

I bought this vehicle back in September 2009. Ever since I bought the vehicle I have had problems with the traction control lights coming on for no apparent reason. This happens when its hot and cold, dry or wet. Just starting the engine makes then come on. I have been back to the dealer for 2 years now for the same problem and they tell me that they don't know why it is happening and can't fix it. My vehicle is now out of warranty and will never be fixed. ?
