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. Notes: The 2002-2007 Chevrolet Trailblazer is known for many things, but perhaps it is most famous for its faulty fuel gauge.

This gauge flip-flops more than a politician during election season. Some report that the gauge says "empty" after a fill-up, while others report the gauge says "full" when they're running on fumes. Either way, there's one thing everyone seems to agree on: the darn thing is just wrong.

Following hundreds of complaints and a few accidents allegedly caused by the malfunction, the National Highway Traffic Safety Administration (NHTSA) opened an investigation into the issue in May 2011. Unfortunately for frustrated owners, no recall has been announced.

I had the recall for the door window master control taken care of about 9 months- 1 year ago. Today, the window or door lock did not work on the driver's side. When I attempted to try the power mirror adjust, the window went down and smoke came from the door panel. I contacted GM and they told me it was pretty much tough luck because they already took care of the recall. I was told that I could take it to a GM dealer to have it fixed but I would have to pay for it. Really" I'm guessing the module was bad and corroded when I took it in for the recall. The recall states that if the window works, seal the problem area and send them on their way. At the time of the recall, the window and other components did work but now the original problem is showing up. I was not allowed to watch recall work being done but obviously this problem resulted from liquid leaking in at one time and causing damage. It just took for today to show up and cause a problem. My interior stinks of burnt plastic. My window is partially down and can not be adjusted. I've read online forums consisting of the same symptoms that I experienced today with my Trailblazer. If this was just a random problem or something caused from my use or negligence, I would man up and take care of this on my own... but it's not. GM used a band aid to take care of this problem and somebody will end up getting hurt or burned yet. I have a prosthetic leg and what if the door locks were locked shut and the thing started on fire" GM listened as I [xxx] about it but didn't have much to offer for a solution. I will take it to a local Chevrolet dealer for their "diagnosis" on a faulty switch and workmanship. It will be interesting to hear what they have to say. I'm very disappointed in what happened today and the stench in my vehicle. I don't want anybody to get hurt but that seems to be the way anything gets solved.

I filled the vehicle up to full with gasoline. The bell chimed shortly thereafter and low fuel light, and warning came on showing low fuel. A few days later the check engine light came on. I received a notice from GM in 2013 about a possible problem with early wear of the fuel sensor causing this problem. They covered the expense of repair up to 120,000 miles. We now have 134,000 miles on this vehicle and the problem just came up, so will not be covered by GM. I have read many complaints about this problem with the Trailblazer online, so I know the problem has been identified by GM. I cannot afford the repair at this time and believe GM is not recalling this fuel sensor problem as they should be doing.

I can smell as if something burning, on different occasion.the headlights would randomly shut off, while driving. I would switch to high beam in order to see. The back hatch window, locks when it wants to. The airbag indicator lights come on and stay on awhile. The vehicle will stall and then accelerate at times. The tire pressure lights, does not come on when pressure is low. The check engine light comes on, and stay on awhile, and then goes off, and comes back on. The climate control heater system blows cold air. At one time the key would not come out of the ignition. Had to continue to giggle the key to get it out of ignition. Noticed my headlights did not come on when I used the remote entry to unlock or lock the door. The windows stall when going up or down. I have contacted GM, but they are telling me that my make, model and year are not part of the current recall. And that the letter they sent me, was to purchase warranty for the vehicle. I feel that this vehicle is not safe due to this electrical problems.

Vehicle stalls and shuts down everyday. Sometimes just stalls then accelerates, sometimes shuts off and I can switch to neutral and restart while coasting. Other times I get shutdown warning light and engine will not restart. I have to coast to the shoulder and wait. Engine will then struggle to restart and engine shakes violently. I wait a few minutes and it will start and run fine, sometime with check engine light on, sometimes not. RPM gauge works sometimes, sometimes not. At time there has been no response when turning key to start. On going issue!! crankshaft position sensor has been replaced 3 times, and issue still persist. Major safety issue!!

On July 18th goldsboro Chevrolet in nc we were told could not seal that leak, because it was to far gone. So he had to order part for it, we set a date to bring back truck on July 23 2013.
