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.

While traveling around town on 3/14/12, I noticed when it got dark that I did not have any low beam headlights. I was traveling on a interstate which caused me to have to use only my high beam headlights until I got home. On the trip home many drivers became very agitated due to me having to drive with my high beams.. I found online that many Trailblazer owners have had the same problems, but Chevrolet has not issued a recall for those problems. I have not noticed or have been told that my brake lights are out at the same time, I just want GM to own up to this defect and offer assistance in paying for this repair.

Drivers door control panel burned causing failure of door locks, windows, etc. Gas gauge continually showed incorrect amounts of fuel causing running out of fuel. Replaced the part and it happened again.Chevrolet took no blame.recently Chevy notified all owners that there is a problem that they will fix up to 1/2 of the actual cost.(my share will be $218 for their mistake) back tail lights have blown out over and over again since purchase. Finally replaced entire units on my own andit continued to happen. Contacted Chevrolet dealer and Chevy customer service.went to dealer and had the taillights repaired but Chevy again took no responsibility but kindly sent me a$1000 voucher for use on a new purchase of a Chevrolet.the dealer repair cost was apprx.$680. Still own the vehicle and will have make fuel gauge repair.

Low-beam headlights go off without warning after about 20 minutes driving. Dashboard lights still on... (not a fuse problem...not a blown headlight)...after car is turned off for a while(30 minutes or so). Lights will come on when car is started...problem repeats itself after 20 minutes or so...the problem is that the driver may not know the lights are off unless the street is extremely dark...making the driver a hazard to others on the road, as well as himself.

While traveling out of town on 9/29/11, I noticed when it got dark that I did not have any low beam headlights. I was traveling over 800 miles on interstate which caused me to have to use only my high beam headlights for the duration of the trip. While on the trip, I stopped at a red light when a gentlemen pulled up next to me to let me know that I did not have any brake lights either. I immediately pulled over and checked the lights and found that none of my brake lights were working. The blinkers and flashers work, but that was all. During the trip many drivers became very agitated due to us having to drive with our high beams, one person became so enraged that they turned around and followed us while trying to run us off of the road. I found online that many Trailblazer owners have had the same problems, but Chevrolet has not issued a recall for those problems. I contacted Chevrolet's headquarters and was told that a recall has not been issued and the cost would be my responsibility.

2006 Chevrolet Trailblazer lt. While driving at night, lowbeam headlights go out. Happens at various speeds, happens sporadically. This has occurred 2 times before. The times before was in September 2010 mileage unknown at the time while driving in my neighborhood. Then on October 08, 2010, at 91,164 miles while driving home on the interstate at 70mph in the occurrences in 2010 lowbeam headlights went out while driving, then independently re-illuminated within seconds. The latest occurrence happened on April 16, 2011 at 10:50pm. I had just driven vehicle 20 minutes earlier and had no problems. My wife used the vehicle at 10:45pm and lowbeam headlights went out while driving at 40-45mph. She stated it took repeated tries with headlight switch to get the lights to re-illuminate. Wife pulled turnsignal arm back and highbeam lights would illuminate the flash to pass feature. No other electrical problems present. This happened while driving in neighborhood at low speed. This is a condition that could be very dangerous at highway speeds. This vehicle has automatic headlights, they come on automatically at dusk, and the headlight switch is left in the automatic mode and never touched. I have owned this vehicle since 19,000-20,000 miles, was a GM executive/demo vehicle.

While driving at night, the low beam headlights stopped working without notice. Stopped at next convenience store, checked all fuses and all were good. Started ignition and lights still did not work. Checked high beam headlights and they worked. Followed up with mechanic the following morning. Could not diagnose problem and referred to a local dealer. Dealer diagnosed problem as being a faulty BCM. BCM was replaced. Approx. 8 weeks later, same problem w/low beam lights not working. Dealer replaced relay. Now low beams work, check engine light has come on and fuel gauge has stopped working.
