My wife was driving home from work at night and the headlights went off and did not come back on by the time she got home (approx. 15 min.). She was on a busy city street which also involves some sharp turns as the drive progresses toward home.

I just saw the recall gm is doing for the 2006~2007 Chevrolet trailblazer. I noticed that other years are not affected specifically mine. My 2009 trailblazer currently has this issues, both low beam head lamps do not work. I have tried everything to get them to work. I have had no luck. Please investigate this issue further. We have to drive with our high beam lights which could possibly cause an accident. Thank you *js

12/11/2015 ODI #10809609.0

The first incident happened as I was in line behind a car at a stop sign, the vehicle just cut off and smoke started coming from the steering wheel. I tried to start it up again but it wouldn't start and was stuck in drive. It was towed and identified as the ignition switch burned. This was back in 2011. Since then, I have had the same problem and replaced the ignition switch four times. The vehicle just stalls and cuts out whenever wherever which is dangerous. I just replaced this ignition switch last year as the vehicle cut off in the loading zone of my job and would not start resulting in it having to be towed. It's 2015 and the same issue is happening again so this has to be a recall or defect on this particular vehicle if not others.

My blower in my 2005 Chevy trailblazer stopped working. The wires melted together on the resister, melting the entire plug. I have seen where this is a common problem Chevy and gmcs have. This is a needed function and if there is a common problem, why aren't these companies doing something to remedy this???!! In one week I found 5 people who have had the same problem with chevys... And I love in a town with only 4k people in it!! I can't imagine the rest of the country!! *tr

Was on expressway traveling about 65mph. Vehicle started to shut off while driving, felt as if it was out of gas, but tank was over 3/4 full. Managed to get to shoulder of road, sat there a minute or so vehicle recranked. I drove home. Took vehicle to mechanic that evening, he tested it the next day and said ignition switch was defective. He replaced switch, vehicle seems fine. *tr

The headlights have failed. All the lights blink while you ride along. The two back doors will not lock or unlock and the front doors are starting to not lock or unlock properly. The items that let you know when a tire is low in air are failing. The last one costing over $100 to fix. I am getting very upset with the electric parts in this trailblazer. This has been going on since purchase. As a photo I can send you a photo of the vehicle.

05/26/2011 Crash ODI #10402783.0

I was driving 2009 Chevy trail blazer and was t-boned by a speeding bus on my side, I had my wife and 2 girls with me, all were wearing seat belt and one of my girls was in her car seat also. The vehicle was totaled, all airbags failed to deploy in the vehicle. I suffered major injuries and I was out from monday through saturday. 3 months later I had an open brain surgery and still under doctors' care. The accident took place in jordan, I was charged with the accident because the report by the police was based on who you know!!!!!! My wife and 2 girls are doing fine except for the psychological affects from that moment. This has changed my life completely. I tried to contact couple of lawyers in the states because I am deployed in kuwait but not having any luck of finding any one intere

When I hit a bump, speed bump, water, rain, anything of the like, I get the stability control light and ABS light, yesterday 9/13/79 I recieved the 4wheel drive maintence needed as well when I had the trailblazer in auto 4wd, this isn't the first occurance and I believe this is going to end up being a danger to people especially those in the northeast, as a former firefighter I have seen what these failures can do not only to the car but to the people as well, for this I believe there should be a recall, so as to repair these issues. And make the Chevy brand reputable again.

05/20/2009 ODI #10269505.0

I have been seeing that when coming to a stop my vehicles idle stays up when it should be kicking down to a lower RPM to slow the vehicle. I have to smash on the brake pedal at times b/c it feels like the truck isn't stopping and the engine rpms stay high. I hear this is a very common problem and heard the factory is doing nothing about it. Im yet to bring it in for this concern but why bother if others are being brushed off by the dealers. I guess gm will only step in when someone gets hurts or even dies from this. *tr

engine 1 complaint shown

05/05/2014 80,000 mi ODI #10586623.0

I was driving down the road at about 50 miles per hour and my car suddenly died...like when you run out of gas except everything shut down..luckily I was able to veer off to the side of the road and almost as quickly as it happened I gave it some gas and it jolted and came back to life. It was like my entire engine just died. It was scary...I think they (gm) may have more issue then they are letting out. *tr
