Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

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.

The contact owns a 2009 Chevrolet Trailblazer. While driving 65 mph, the headlamps failed to illuminate. The contact had to activate the high beam lights in order to continue driving. The contact learned that she needed to replace the fuse. The vehicle was repaired, but the new fuse only lasted six months. The vehicle will be diagnosed again per the manufacturer. The approximate failure mileage was 80,000.

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.

As I was driving in my yard I happened to bump the ignition key and the motor cut out and died. This caused me to not be able to turn and avoid bumping a post causing some body damage, but I was able to avoid hitting my friend in the yard because he had moved from by the post a minute earlier. I have had one more time with this problem, but not had a problem since, but I am now experiencing an occasional rough running engine. Could this ignition switch on this year vehicle need to be recalled also?

While driving at 30 mph, low beam headlights went out. High beams functioned and fog lamps functioned. Drove app. 5 miles and pulled off road and turned the car off. Turned the car on and the lights still did not function. Left the car for 2 hours and returned. Started the car and lights went on for 1 mile and then went off again. The lights went on again the following day for less than a mile of driving.

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.

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 Chevy... and I love in a town with only 4K people in it!! I can't imagine the rest of the country!!
