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: The Trailblazer emerged from an "upscale trim line" of the Blazer, but there's nothing upscale about its transmission problems or its wonky, unpredictable headlights.

2002 Chevy Trailblazer. When you go to start the vehicle and if the vehicle has a dead battery, you can not remove the key from the ignition. The ignition locks up and you can't remove the key. I guess this is actually part of the anti-theft devices. This is very unsafe in that if you have to go to seek help. The car is unlocked with the key in the ignition.

The light on the 4 wheel drive knob is always jumping back and forth from 2 wd to 4 wd. The service 4 wheel drive light came on several times. The vehicle was taken to my Chevrolet dealership and it took them 5 days to figure out the service 4 wheel drive light was due to the ignition" my ignition does not start properly anymore. The lights on the 4 wd knob still blink. I do not know if the vehicle is safe. The dealership claims it is safe"
