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: Carrying the not-so-proud traditions of its 2002 predecessor, the 2003 has a handful of instrument panel malfunctions that can leave you guessing your speed, engine temperature or how much gas is left in the tank.

Problems with 2003 Chevrolet Trailblazer resulting in an accident. When the consumer attempted to apply the brakes, the vehicle started to skid. The consumer tried to turn the wheel to straighten out the vehicle, but the brakes locked and the steering wheel continued to go toward the left. The consumer was unable to maintain control of the vehicle and subsequently collided with a semi tractor trailer. After the impact, the consumers vehicle continued going left toward oncoming traffic and eventually went left into a ravine/ditch. Throughout the entire incident, the consumer had her foot on the brake and the vehicle would not stop or slow down. The consumer also stated the air bags never deployed.

While coming to the end of an on-ramp to 295 w, the vehicle suddenly began steering from left to right; I had absolutely no control; the brakes didn't appear to be helping at all, and I was only driving at a speed of aprox. 30 mph as always when I drive this on-ramp. I've "never ever" had a problem as this occur with any vehicle I've driven on this or other on/off-ramps. It was scary. Luckily I did not hit on-coming traffic but did, however, hit a guardrail. My 8 yr. Old was also terrified, but luckily we did not sustain injury.

When applying pressure to the brake pedal pedal goes down to the floor, and the vehicle doesn't stop immediately. Dealer cannot determine the cause of problem.
