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

While traveling westbound on 192 in osceola county between narcoossee road and nova road there were several barricades 4 to 5 inches in the traffic lane. I was in the left lane with the barricades over the yellow line on the left-hand side of the road. This took place at approximately 8:15 am while taking my children to schoo, during the morning time traffic. My vehicle struck a large round orange barricade on the left side of the vehicle. I attempted to maneuver and avoidance however I was traveling next to a semi and was unable to do so. As a result my vehicle now has a scratch on the left side. I then called dot to report the damages and to have the site investigated for future incidences. The company conducting the construction work is jr davis construction. There is not a pull off zone or a place I felt safe stopping to directly speak with an individual in charge. I travel this road several times a day and have never seen the barrel barricades in the road as they were this morning.

On Saturday, August 1, 2015 at approximately 8:55pm my mother was involved in a 1 car accident on baum rd located in tallahassee, fl. She was the only passenger determined to be in the vehicle at the time of the accident. According to the crash report, D1 (driver one) was traveling westbound on baum rd going the normal posted speed of 55mph, when she veered towards the center of the rd and suddenly turned right veering of the right shoulder of the rd and striking several trees on the drivers side and front end. D1 was wearing her seatbelt and managed to exit out the drivers side window before coming to her final resting place on the shoulder of the rd. When I went to retrieve my mothers things from her Trailblazer, I noticed that no air bags had deployed. And as fast as my mom was going and the type of impact & damage her SUV sustained, I would think and hope the airbags would deploy in this type of accident, thus preventing serious injury or death. My mom was not so lucky, and myself and my family have endured great pain from loosing her so suddenly.

Driving I-85 North bound on the morning on 6/15/2015 headed to work when the rear passenger tire blew out causing my 2004 Chevrolet Trailblazer to cross over into another lane then back into the lane I was in, spin uncontrollable, all of a sudden the steering wheel started spinning and then the vehicle just shut down, steering wheel locks, the car comes to a stop and slams into a guard rail where I am facing South bound traffic, none of my air bags deploy, I have a neck and back injury that to this day I am still being treated for and my passenger who was a coworker riding to work with me that morning also had a back injury. My vehicle was deemed a total loss by insurance company could not be repaired, lost time from work, still have medical bills, occurring, although I have full coverage insurance but because it was a one vehicle accident there is nothing that can be done about loss wages. Just had these tires put on my truck about 6 months ago, heard about people passing these bad tires on as new tires, don't know if this is the case or not. Don't know why air bags did not deploy, don't know why steering wheel spin then locked up, thank god it was not worse! state trooper said it could have been worse from the way I landed.
