Both side curtain airbags deployed while driving down the street. The driver's seatbelt tightened then locked up. There was no obvious reason for the airbags to deploy. the vehicle was taken to a Chevy dealer to see if it was on recall list but they said it was not. Vehicle was referred to a body shop for estimate for repairs...$6,435.00....if you can find the parts. driver was shaken up by the deployment but not injured.

I was driving on the highway just reaching 55 mph, that is when all of a sudden, my suv stalled out with no warning no sound nothing. I tried to restart it and sounded as if it was trying to start but wouldn't. after a couple of times of trying that is when a tow truck came and as he was putting my suv on the flat bed I noticed huge amount oil on the ground. I got it towed to Chevy dealership for service and that is when they told me that the 6th cylinder cracked also a rod went through causing a hole in the engine block. I asked what could have caused it, because I'm on top of my maintenance and my suv only had 94,000 miles on it. That is when he explained to me that it was nothing that I did and that there was nothing that I could've done to prevent it and that there was nothing I did wrong that caused it. So, the leaves me asking, isn't that a manufacturing issue?

The contact owns a 2008 Chevrolet Trailblazer. The contact stated that while parked in her driveway, the passenger side door caught fire without warning. The fire occurred overnight and in the morning, the contact and her boyfriend discovered both her passenger side door and front passenger seat melted. The contact believed that the fire smoldered overnight and eventually burned out on its own. The fire department was not notified and a fire report was not filed. The contact called the dealer and was informed that there were no recalls on the vehicle. The contact's boyfriend discovered that the wiring inside the door had melted which may have caused the fire. The manufacturer had yet to be notified of the failure. The vehicle had yet to be serviced or diagnosed. The failure mileage was approximately 206,000

While driving home at approximately 9:30pm, my eighteen year old daughter experienced the headlights failing to come on after dark with the automatic headlight-on feature. She turned on the headlights manually, and the low beams still were not working, but all driving lights and high beam headlights were working. I assumed that the bulbs were burned out, so replaced both the driver and passenger side bulbs. The low beam headlights still failed to come on either automatically or manually. I Googled the problem, and multiple people have reported this exact same problem, and some stated that there was a recall due to this problem. I am unable to find either a recall or a service bulletin for this issue.

WHILE TURNING LEFT AT LOW SPEEDS STABILITRAK ACTIVATES SHUTTING POWER OFF TO THE WHEELS ONCE YOU RELEASE GAS PETAL FOR 5-10 SECONDS STABILITRAK WILL RETURN TO NORMAL AND ALLOW POWER BACK TO WHEELS. THIS IS A SERIOUS SAFETY ISSUE BECAUSE IF YOU PULL OUT ON THE HIGHWAY OR ANY STREET AND YOU LOOSE POWER, YOU COULD GET HIT
