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.

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.

When I make left or right turns the truck shuts off all the gauges read as normal except for the RPM's I loose power stearing and cannot exelerate it does not happen at an spacific time or place it is just random so I do not know when it may do this some days nothing happens other days it happens 2-4 times and it is a bit scarey when you are making a left turn especial I am not sure what this is or what is causing it but this I have had the battery and the alternater checked and other components checked out but they could not find anything and of course while the dealer had it did not do it so I am not sure but this is deffentley something that needs to be looked into like I say when I make turns I lose power, loose my stearing and the ablity to accelerate and all gauges read normal except the RPM's they are the only one that go down to zero

I was driving approximately 40 mph and all of a sudden I lost power in the vehicle. I had no acceleration, I lose power steering. Vehicle was still powered on but I could not pick up speed or steer vehicle. I had to pull over to the shoulder and cut off ignition then restart vehicle. Once restarted I had full functionality again. This has happened 4 times in the last 30 days. Vehicle has also started stalling when attempt to start up.

Driving down interstate 79 in Pennsylvania at normal speed when my airbag light lit up and my air bag disengaged flashed, followed by more lights on the dash going on, and tracking disengaged flashed, then engine light came on, engine failure flashed as I started moving toward the right hand lane in heavy traffic. Just as I made it to the right lane my power cut out and I was going 20 - 25 mph in two seconds flat. I swerved to the berm of the road as the four wheeler semi truck that was behind me nearly clobbered me. I inched on the berm at 20 mph to the bridgeville exit and got to the colussy Chevrolet dealer where my car stopped dead in the service dept. First, they thought battery, but the battery was fine. It was ignition switch failure which caused my air bags to disengage and my losing power. I was lucky I wasn't killed!! the cost of repairs was $337 but I was told that my 2006 Chevrolet Trailblazer was not on the GM recall list, even though I had the exact things go wrong with the vehicles on the ignition switch recall list. And they repaired it the same way, with no guarantee that this wouldn't happen again!!! this is not a "vehicle" recall, it is a "parts" recall and my vehicle had to have the ignition switch replaced. I called the GM ignition switch recall hotline and they escalated my case up and up and everyone said the same thing....they are sorry for my distress, my inconvenience but my vehicle is not on the recall list so they cannot replace the cost to repair my vehicle. Perhaps if the semi truck that was behind me killed me, they might acknowledge my safety concerns for the ignition switch (part) and not my vehicle!!!

I was driving down the highway when the check engine and low power lights came on. I lost all acceleration and my RPM's dropped to nothing. Codes that came up were for the throttle body. I read a complaint that states GM knows about this issue. Why haven't they done anything about this?

This SUV is nothing short of a rolling hazard. The "check engine" light is on and off, again, for the past 6 days. Tried to start it up this morning and the engine light was on. As soon as I was about to back out of the driveway, the vehicle started to idle in a manner that caused the rpms to crank way up and then plunge until almost shutting the engine down with violent shaking and loud roaring noise. Yesterday, the stabilitrak warnings (2) came on the dashboard - I was only going 3 mph exiting a parking lot. There was no inclement weather and the road was bone dry. I haven't been able to pick up power and it seems like the more I press on the gas pedal, the slower I go. I live in houston and the traffic conditions really don't allow for a "sudden stop" or loss of power on a freeway where people are traveling at an average speed of 70 mph. I have had 4 other instances of this "check engine" light in 3 yrs. The dealer isn't much help and GM Chevy is no help at all!!!! the tv commercials they run about Chevy trucks are "like a rock" are very true. This Trailblazer is as useless as a rock.

This is the second time this has happened - what happens is I will be driving ( speed once at 35 once at 60 ) and my Trailblazer just shuts down. Instantly. You have no power to get over to the side of the road. P0601 code - this is what shows on my mechanics system. However, when you research that code online. Some folks have spent thousands trying to stop this issue and no resolve. This is highly dangerous - you go from 60 to nothing. My TB has less than 50K on it.

My son and I were out today shopping locally only about 1 mile from our home. The car was fine and everything was great until all of a sudden, the acceleration on the car started to decline even though I had my foot on the gas the car just seemed to do nothing. I was in the middle lane and traffic was vicious, I turned on my hazards and attempted to try and push on the gas. I car came to a stop but the engine was still running, it felt like I was in neutral but I was clearly in drive. I contacted onstar they called the police to make sure we did not get in an accident, as I stated earlier, we were in traffic. I received a push to a safe side of the street and tried to restart the car over and over again, the car started up fine, it just would not go anywhere, no movement. I had to get it towed to my home because it was 110 degrees and I had my youngest child with me. We waited 2 hours for the tow truck, I was dehydrated and faint by the time we made it home. My husband contacted the dealership as we just purchased the car in February of 2013 from ezcarsandcredit in riverside ca, they said don't worry about it, they will have the manager call us back to take care of the problem, that was 4 hours ago and still no call.

  • 48,730 miles
The contact owns a 2006 Chevrolet Trailblazer. While the contact was driving 10 mph he attempted to pass the vehicle in front of him reaching 40 to 50 mph and noticed that the accelerator pedal had become stuck to the floor and the brakes would not stop the vehicle. After several attempts at slowing the vehicle by using both the brakes and the hand brake, the consumer activated the emergency lights, switched the transmission into neutral and continued to use both the brakes and hand brake, bringing the vehicle to a stop. After stopping the vehicle and turning off the engine, the consumer had to physically pull the accelerator pedal off the floor with his hand. The consumer took the vehicle to the dealer and they replaced the throttle body. The current and failure mileages were 48730. Updated 3/8/10 updated 05/13/10.
