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.

CarComplaints.com 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.

Speedometer cluster malfunctioning. After seeing that this is a very common issue with these models and others that did have a recall I felt it was my duty to file this complaint. The speedometer reads 70 when I am stopped and well over 120 when I' doing 30 as per my gps

The front blower stopped working while my wife was coming home from a trip with my kids.the temperature outside was 28 degrees the windows fogged up and she hit a deer that she would have seen if the windows weren't fogged.I have replced the blower resistor switch which had a burnt connector it lasted 3 weeks and has gone out again. This is a very bad problem because even when you have this problem repaired it still malfunctions without warning. This is putting myfamily at great risk. Onthe other hand had I known that there was problems with Chevy trailbrazers and defective parts I would have brought a Toyota.

The cluster/instrument panel on many 2005 Chevrolet Trailblazer does not work, the gas gauge does not work, along with the speedometer, and the battery meter. The failure of these functions can cause speeding/ driving to slow, which could intern cause an accident. The gas gauge always shows that the tank is empty even after a fill up, which could cause you to run out of gas, and get into an accident. The only way to solve the problem is to replace the cluster panel.

The contact owns a 2005 Chevrolet Trailblazer. The contact stated that one year ago the speedometer failed which made it impossible for her to determine the speed she was driving. The fuel gauge was also displaying the incorrect reading, and the fuel light remained illuminated. The vehicle was taken to a local mechanic who performed a diagnostic test for the fuel failure which indicated that the fuel sending sensor was defective. The local mechanic did not perform a diagnostic test for the speedometer. The vehicle was not repaired. The manufacturer filed report 71-930473192. The failure mileage was 10,000 and the current mileage was 110,000.

The contact owns a 2005 Chevrolet Trailblazer. The contact stated that the speedometer malfunctioned. The vehicle was taken to a local mechanic who performed a diagnostic test and informed her that there were no error codes or warning lights illuminated; therefore, they were unable to repair the vehicle. The contact notified the dealer in regards to the failure and stated that there were problems with the chips in the computer and they needed to be replaced. The dealer wants the contact to pay for an additional diagnostics test although the local mechanic completed one. The manufacturer was not contacted. The failure mileage was 81,000.

Traffic was horrible bumper to bumper, I was driving and realized not to rush so I stood in the first lane, as I was driving bumper to bumper I always drive within one car lengths in case I get rear ended. As I am driving bumper to bumper all for a sudden next thing you know my car just suddenly accelerated at incredible speed I manage to swerve into the emergency lane to avoid causing a multiple car pileup my car died instantly I started it up again and it just wanted to take off as it did before I turned the car off thinking to myself my god what just happened and what is going on, I am trying to calm my 12 year old child because it was the most frightening thing I am my family ever went thru. I press the break and just relax for a second and started the car up and it was fine. However, my nerves were pretty much shaken, I had taken the car to jj auto shop in hayward who is ase certified he did a diagnostic on the vehicle he said he could not verify what I was saying, no error lights and the history was clean. He also mentioned the computer at times does not pick up a split of a second acceleration. He believes my story and said everything is done thru computer so there is no finding as of the moment. I was not sold on that but he also recommend I could change the body throttle @ $700 but he said I just don't want you to buy the part so you could just drive in the slow lane and if it happens again to shift the car into neutral and turn it off asap> my thing is since car's are computerize this should have why is it they could not verify my situation and also body throttle what he was looking at and what Chevy thinks it was! so my complaint is for Chevy did they overwrite software to overlook sudden acceleration? the only major issue I had had with my vehicle was when the speedometer went crazy as I was driving 110 but was really going 35mph

My speedometer dropped to zero as I was crossing railroad tracks, and my cd player stopped accepting cd's during that same time period for no apparent reason. The gauge later stuck at first 20 - 15 mph, and then to 10 mph when the SUV is stopped. After about 2 months, it corrected itself. The gas gauge then went out. It would register the tank as empty no matter if it was filled. This began 2/2010. I, a disabled driver, have run out of gas on a deserted road 12:15 a.M. in the winter due to having to calculate miles driven with the tachometer to determine approximate gas consumption. Unfortunately, that calculation doesn't account for engine idling in traffic jams. I sat in the middle of the road in my cold SUV praying no one came around the curve and slammed into me since I ran out of gas in the middle of a dark rural road. I was terrified in this situation and rarely drive at night if I can help it because of the manufacturer's known defect and negligence. I have paid over $500 to repair these manufactures defects, only to have them malfunction again within 1 week of repair. I was told by the mechanic that he would not attempt to fix it a second time. Once again, my speedometer is no longer registering the correct speed, and I have been pulled over by a police officer for speeding. I showed the officer my speedometer, and to my surprise he let me off with a warning and told me that he has pulled over other Trailblazer drivers for speeding who in turn had the same or similar issues with their speedometers. I have had interior lights malfunction, and driver side head light malfunctions where the light keeps going out. The headlight was checked by a mechanic and was not deemed loose or blown.

I bought a 2005 Chevy Trailblazer in March 2010 and have had multiple problems since then. My check engine light came on while I was driving and the ac stopped working, it was diagnosed as the ac fan blower. I replaced the blower but that didn't fix the problem. I then replaced the resistor and the harness. Finally when I replaced the harness the ac started working again. The next problem is with the gauges. My fuel level gauge is erratic and never tells me the right fuel level and the cruise control randomly stops working. It has stalled numerous times because the fuel gauge is reading wrong. I'm afraid someone might hit me and my family. I've invested hundreds of dollars for problems that GM needs to take responsibility for!!

Gas gauge malfunctioning, engine light keeps coming on and off. In looking at different web-sites, this is common for this vehicle. I purchased the vehicle on 06/20/2010 and have had several things go wrong in the (8) months that I have owned it.

[xxx] of Chicago, il, petitioned the Agency in a letter dated November 27, 2009. The petitioner requests that NHTSA open an investigation into the performance/reliability of the fuel level sensor installed in model year 2005 Chevrolet Trailblazer vehicles. The petitioner alleges that the fuel tank level sensor is defective and could result in a subject vehicle running out of fuel, stall, and being rear ended by another vehicle. ODI will evaluate the petition for a grant or deny decision. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Fuel gauge, oil pressure gauge, and speedometer completely stopped working. I also had to replace the ac/heater system because of the wiring harness. I had to fix things twice for a cost of over $600 in 8 months! GMC really needs to recall these things because so many vehicles have had problems. Every complaint on here is the same! recall it now! it is not our fault... it's yours so fix it!

The car originally stalled while driving on 95 South. Now it randomly stalls on an average of twice a month. It is very dangerous, power steering shuts off completely. In order to get in running again, I have to open the fuse box where ever I am able to pull over, usually on a highway and push up onto one of the fuses. I brought it to the dealer and they fixed it for just over $100. After about a month it began doing it again. So the problem has not been fixed.

The fuel gauge, oil pressure gauge and speedometer have stopped working. The fuel gauge reads empty when the tank is full. The oil pressure gauge hovers around 80 or points straight down. The speedometer will read 120 mph when stopped at a red light, or will read 30 mph when on the highway traveling at the same speed as other cars, generally in the 55-65 mph range. The speedometer issue is incredibly unsafe, as you have no way to know your true speed. The oil pressure gauge is unsafe as well, as you have no way to know if/when you're really having an oil pressure problem. My calls to GM have resulted in no resolution, as I was told that I shouldn't need the speedometer since I can "feel" how fast I'm going (as stated by a GM representative).

The contact owns a 2005 Chevrolet Trailblazer.

He was also unable to determine the temperature of the vehicle. The vehicle was not inspected by the dealer nor was it repaired. The failure mileage was approximately 65,000.

I have a Trailblazer lt and the lights have a serious flickering problem going down the road. It is actually dangerous! when you are driving down the road the lights just flicker to oncoming traffic. Chevy claims this is a normal problem with Trailblazers. There has been no corrections for this problem. I explained how would this person feel if they had their child in the car when your Trailblazer was facing oncoming traffic and your lights flickered causing the opposing traffic to come into your lane? this is not safe....someone needs to do something about this issue and find out what the problem is and recall it!!!
