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.

Transmission cooler lines are corroded and leaking fluid all around the front passenger side wheel well. These lines will need replaced before the transmission fails. The frame is soaked with transmission fluid and this is a potential fire hazard if the fluid leaks onto the exhaust or catalytic converter.

2005 Chevy Trailblazer. Bought the vehicle used in 2008 with only 33,868 miles on it. Have 78,158 on vehicle now and last month had to have the radiator replaced and transmission rebuilt. The place that did the repairs told me he gets about 3-5 Trailblazers a year with the same problem. He had 2 folks call about the same issue while mine was on the rack. Seems the radiator develops a small leak in the system that cools the trans and causes the transmission to fail. Had no real issues until last month when vehicle would not come out of 3rd gear. Could put auto transmission in to 1 or 2 and then be able to take off from dead stop and shift into drive to get the vehicle home and then to shop. Have looked online to see if there was a recall on this issue and there has not, but appears there have been other complaints about this issue. Total cost for vehicle repair was $2,814.17.

Acceleration sluggish at first. Then the RPM's would increase without any acceleration. Finally, would not shift out of 2nd gear and if went above 30 the RPM's would increase without anymore power to the wheels. Found a transmission hose blown also.

The contact owns a 2005 Chevrolet Trailblazer. While driving approximately 35 mph, the contact lost control of the vehicle, crashed into another vehicle and swerved off of the road. Prior to the crash, the contact heard a loud banging noise near the rear end of the axle. The front drive axle and the drive train connected to the rear axle were destroyed. The vehicle was towed to his residence and it was not repaired. The manufacturer stated that they were unable to offer him any assistance with the failure. A police report was not filed. The failure mileage was 115,000. Updated 06/17/11

While on the highway to Florida from Ohio I felt a budge and then heard the vehicle sound like it was down shifting and the rpms were high. I pulled off the side of the highway and headed back home doing 40 mph since the vehicle would not shift past 2nd gear. Also the vehicle shifted gears harshly. Took the vehicle to the dealership and they had informed me that I needed a new transmission. I have read hundreds of other complaints on the this same subject. I am assuming that most people don't know where to report such incidents.

Went to dealer for vehicle inspection and oil change on my 2005 Chevrolet Trailblazer. Was told that the sensors are indicating that there is moisture getting into my transmission due to a issue with the dip stick not sealing properly. Was told it would cost $192 (parts and labor) to repair. That it is not covered under warranty. However, I was told that if my transmission did go out due to this problem, and my vehicle was still under the warranty, that the warranty would cover a new transmission. Doesn't make sense that if there is a defect in such a minor part as the dip stick seal, why the warranty wouldn't cover the repair.

I have a 2005 Chevrolet Trailblazer with 75,000 miles on it. With no warning, my transmission went out. The car is well cared for and regularly serviced. Our local dealership explained that I had no power train warranty, and that they do not repair the transmission. The cost to me for a new transmission would be $2720.31. Updated 10/27/10.

Trailblazer

  • 63,100 miles
We were driving on I-85 in Virginia with cruise control on when the engine started racing. We limped into a service station at the next exit to have the Trailblazer looked at. We only had 1st and 2nd gear remaining on our transmission and had to have the SUV towed to the next major city and spend the night until the dealership opened on Monday. The end result is that the transmission failed at less than 64,000 miles. I was told by the dealership that the transmission housing essentially disintegrated and there were a lot of metal fragments inside the housing which were a major factor in the transmission failing. This level of catastrophic failure of a major drive train component should not occur at so low a mileage. We, as the consumer, were forced to pay $3200 for a new transmission. Plus the costs of hotel rental and a rental vehicle to return home and missing work to address this issue.

My 2005 Trailblazer instrument panel constantly fails - the speedometer stops working which is a safety issue. The gas gauge has been fixed once already and is now broken again. The vehicle has power surges which is another safety issue. The transmission shifts the car up and down when trying to slow down causing power surges. This is another safety issue. The following are other issues which this model vehicle: Stereo cd player stopped working, the check engine light comes on when the gas cap light, the lights flicker also. I ought this vehicle used and with a cracked front bumper which the dealer didn't fix (dealer stuck a little bondo on area and repainted it so I thought it was a new bumper when I accepted the car after repair. It cracked in a matter of days) and I know this was caused due to the surges in power. A severe safety issue. The vehicle has serious electrical problems the Chevrolet should stand behind and fix. It is not fair to the consumer. I have checked the web and have read many, many other similar complaints. Chevy owners should fill a class action lawsuit against Chevrolet if they don't do a recall and fix these problems. I experience a fender bender accident when my vehicle didn't stop and bumped another cars back bumper causing an accident and an insurance claim. I am fed up with this vehicle but can't afford to replace it. Linda vanauken

Normal driving, I noticed some liquid spots on the driveway. After inspecting, I found that the transmission oil cooling line is corroded through, leaking transmission fluid. My Chevrolet Trailblazer has less than 60000 miles and is 5 years old. One line is clean, the other is corroded beyond repair. Transmission oil cooling lines have to be replaced.

While driving on the highway, my truck RPM's began to rev, and I began to lose speed. My Trailblazer would not shift out of second gear now. I discovered a leak into the transmission cooling line and replaced it. I've also changed the fluid and filter. After taking my truck to a local autozone for a code scan, which brought back no codes, I took the truck to my local dealer for a diagnosis. They charged me $105 to tell me that the truck wasn't "throwing codes" I already knew that! they told me that it was going to be approx. $800 just to pull the transmission apart to find the problem and $400 to put it back in. That doesn't include the cost of fixing it! after consulting with an ase certified mechanic, I changed the tcc (transmission clutch converter) solenoid to no avail. The problem still exists! GM will offer no assistance until I pay the dealer to disassemble the transmission, then "there is a possibility" that the fix will be covered. This vehicle has not done any towing and only has 56,600 miles on it! there is no reason for a transmission failure!

The contact owns a 2005 Chevrolet Trailblazer. While driving approximately 50 mph, the contact heard a loud noise outside the vehicle. The transmission began to slip and there were no warning indicators illuminated on the instrument panel. The vehicle was taken to an independent mechanic on two separate occasions for inspection. The technician stated that the alternator failed. The warranty expired on the vehicle and the manufacturer is in the process of being notified. The vehicle is able to be driven and has not been repaired. The VIN was unknown. The failure mileage was 72,000 and current mileage was 76,000.

Trailblazer 6-cyl

  • Automatic transmission
  • 50,000 miles
I purchased a 2005 Chevy Trailblazer on 4/15/05 shortly there after I was having problems with a whining sound. I took it to a dealer and I was told that it was the ignition pulley. I contacted the corporate office of Chevrolet to inquire about assistance with payment considering I was about 3, 000 miles over the warranty. After several calls Chevrolet absorbed this cost. Then in Sept. Of 2005, my husband totaled his car and I purchased a 2005 Trailblazer for him. Again this car began making similar noises and my husband was driving home with our 2 year old son and the car began smoking. My husband immediately pulled off the road and contact roadservice. Once we took it to a mechanic he said that it was the ignition pulley which caused the transmission to die. We took it to a Chevrolet dealership and they said that was the transmission. I contacted the corporate office once again and this time they would not offer any financial assistance. It seems that the dealership said that it was the result of an oil change that did not occur at the 3000. They, the dealership based this off of a sticker that was in the window of the car. When I went to look at the car they was no oil sticker in the window. Despite that, I had contacted the Chevy office about the same whining noise that I heard in my car (the ignition pulley) that my husband was experiencing in his car. This is still not resolved. We were told to fix this car it would cost $10,000, yes, for a new transmission. We have since towed to home in order to avoid storage fees. Here sits a 2005 Chevy Trailblazer with approx. $50,000 and a new transmission is needed. We do not have the money to fix this and also pay the car note on it as well. As a read reports, this is a similar problem with many many Trailblazers. There needs to be a recall on this vehicle for faulty transmissions!!!!!

I own a 2005 Chevy Trailblazer and I have encountered numerous problems since purchasing this vehicle brand new from the dealer. I have had to have sensors replaced, fuel tank has had to be worked on, and now the main most costly is I am having to replace the transmission. This vehicle has approx. 84,000K miles on it and is only two years old. Please help to see if this should have been a factory recall. I have always had my vehicle serviced at the dealer where I purchased it at.

Transmission started acting up about 2 weeks ago at right around 47,000 miles. It's gotten to where I cannot go more than 45 miles an hour or so and it takes me 5 minutes to accelerate to that point. I am taking it to the dealership, even though my warranty is expired by 11,000 miles, and one month!

While driving I automatic transmission failed to work in the drive position. It was taken to dealer for repairs, where it was found that a complete failure of transmission occurred. The vehicle was safely stopped on the side of the road. Their were no injuries, but under different circumstances this occurrence may have resulted in severe injury or death. The vehicle had only 51,653 miles at the time of the incident. The transmission was overhauled and the vehicle was returned 5 days later. The required first service of the transmission was not scheduled until 100,000 miles.
