Engine dies while driving (losing propulsion, steering, brakes, etc.) and the key will not restart when turned forward (in neutral), while coasting, but will restart when the key is turned back and then forward again. in this case, coasting down and braking and turning right, possibly with right turn signal on. died right before starting to turn the steering wheel at about 15-20 mph. it was a clear dry 100 degree afternoon, on smooth pavement. we live on a bumpy dirt road that is just over a quarter of a mile long to reach our house. similar to other gm ignition key / no air bag recall programs for similar model year vehicles, such as the hhr. there is no recall, but how many people does this happen to? any deaths, yet? i don't believe the air bags may have worked, should we have been involved in an accident. there was no information shown in the diver information center display (dic) and there were warning lights on in the dashboard, to indicate that the power was on to the instrument cluster (ic), but that the motor was ...

My window in the rear passenger side malfunctioning.... it would let down on it's own.this happens when my vehicle in drive and when park.

I was driving down the highway and my lights just went off. the interior lights were on but the headlights went out. i stopped the car, turned it off, waited a few minutes and turned it back on. the lights did not come back on. the high beam lights still worked and i drove home with my brights on. when i got home and turned off the car i tried them again and this time they came on normally. this is the third time this has happened at night that they just went off.

While driving both of my headlights stopped working. this effected both daytime running lights and low beams. high beams are still operational. researching the issue easily shows that the issue is a faulty headlight relay. i even tried to replace both bulbs and checked all fuses to verify. i contacted the service department of frei chevrolet in marquette michigan and they refused to even tell me if they had the parts in stock to resolve the issue. this will be the last time that i deal with them.

My son and i were driving 65 mph on the interstate.... car just died, no warning. i had to veer suddenly to the right to make the ramp or take a chance on the shoulder. since this first time the car has also not wanted to start. i thought it had to do with the alarm locking me out , but it appears it is the ignition switch. the car has on multiply time died while i was driving. i've tried reaching out to chevy and gm but, each is wanting me to pay for a diagnostic. i do not have the money to spend on this. i don't want to die because i can't afford to pay for their faulty ignition. please help us.

Takata recall, my 2008 chevy trailblazer has 110,000 miles on it and for the past year it seems that i've been having electrical problems. this problem have been going on for about 6 month. every now and then my car wont start and i have to get a boost off to get it started again. i took my suv to get the battery and alternator checked and they said everything looked great. then after that i noticed that my rear brake lights were going haywire with blinking lights going on and off and the car was not on. after i noticed the blinking lights, i went to try to start the car and it was dead. also, my front passenger door motor went out , so the window wont go up or down.. this is very frustrating can someone please tell me if there are recalls on any of these problems.

I recently started having problems, one being my brake lights don't always work. i took it to a local chevy dealer and was told it all had to do with an electrical problem as is impossible to fix. shouldn't my vehicle be recalled? i'm a safe driver and it's a bit upsetting knowing that i don't know if and when my break lights are working. especially when i have small children with me. we recently moved, as my husband was following me, he was the one that noticed my brake lights weren't working.

On )9/16/15, i was driving my 2008 chev trailblazer on the highway at 55mph and the ignition switch failed and the the vehicle rolled to a stop. it would not start again and was towed by glenn's towing service faribault mn 55021 to harry brown's service center faribault mn 55021. they replaced the ignition switch and charged $389.25. i'm concerned if they put in the same switch with a defect or one that has been improved to eliminate the defect as chevrolet has been recalling ignition switches on other vehicles but not the trailblazer. i was lucky i didn't get hit when the truck stopped.
