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: It would be ill-advised to blaze any trails with the 2004 Trailblazer. Its faulty fuel gauge could leave you stranded.

While stopped behind a truck at a traffic light, my 2004 Chevy trail Blazer started moving forward while my foot was still on the brake pedal. My vehicle would not stop and collided in the rear of the truck just ahead of me while stopped at the traffic light.

Had P0128 code for about 1 year. Replaced thermostat after P1680 code, reduced engine power light came on. Reduced engine power light went away on next crank up to move vehicle and change thermostat. ABS and brake lights both on intermittently. Tachometer has been sticking and speedometer showed erratic signs around 55 mph. Now all gauges going wacko or not working at all at times. Temperature gauge wrapped completely around without even starting cold engine. About a mile later, instrument panel lit completely up then went away, gauges reset, and ran fine with properly operating instrument panel... at least until I got home. Then wacko stuff again. Reset PCM by disconnecting battery cable, now things seem fine... for now. I'm told to redo bad ground on ecbm before suspecting bad ABS module and to replace ignition switch before suspecting bad instrument cluster and PCM. However, dealer analysis said ABS module got moisture in it and the instrument panel needs to be replace. First is a $1000 ABS module, second is a $400 panel, both have labor charges additional.

The contact owns a 2004 Chevrolet Trailblazer. The contact stated that the transmission sun gear was faulty. An electrical component was burning inside the vehicle, along with ABS failure. The vehicle was taken back to the dealer and they stated that there was no guarantee that the vehicle was working properly. The oil needed to be changed, so the contact changed it himself. The failures occurred right after the vehicle was purchased from the dealer. The dealer performed a 120 point inspection, but they never repaired the vehicle. The failure mileage was 101,576.

We are having the same safety issue as so many others are having with our 2004 Trailblazer. The gauges do not work properly...particularly the tachometer and speedometer, but also include our headlights and radio which both occasionally flashing out for a second or so. This started happening around 47,000 miles. And since we are filing this complaint we may as well mention how our rotors and brake pads completely broke down at around 48,000 miles.

Rear brakes failed due to vehicle design flaw resulting in rear driver's side brake hose remaining in contact with emergency brake cable assembly. The brake hose is too short and was either designed, installed or not routed correctly. At highway speeds the loss of the rear brakes in an SUV will potentially result in a crash or a roll over, in an emergency braking situation, with loss of life.

On Tuesday September 9, 2008 while driving my 2004 Chevy Trailblazer and attempting to make a slow left turn the power brakes failed. The brake pedal became very hard to press. This happened on two more occassions I was more than (30) miles from home in the evening about 7pm. On Wednesday September 10, I took the vehicle to ridgeway Chevrolet in lansing, Illinois to have them checked. I was told there was no vacuum to the booster. That they had to clean out the plugged vacuum ports. I was also told no parts was needed but the cost would be $240.57 which I paid. The service order # is 151828.

I have had my trail Blazer for 1 yr and 1 month. In that time I have had to replace front and back pads and rotors, ball joints, catalytic (sp) converter, and now they just told me I have to replace the head gasket on the manifold. What the hell is going on with this vehicle. I no longer feel safe driving it. The other day the radio just stopped playing and then the service 4 wheel drive light came on.
