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.

Vehicle wanders from lane to lane requiring constant correction. This condition causes fatigue when traveling at highway speeds. Vehicle driver can not take their attention off the road for more than a few seconds, especially in windy conditions or heavy traffic as the vehicle will wander. This causes premature tire wear tires must be replaced in as little as 10,000 miles and the cost is about 1K for all four tires. Problem two. Cruise control will not set or cancel must be turned off, or the brake depressed or the control buttons are inoperative pressing the cancel button does not turn off the cruise and if it does, after numerous attempts, the cruise will not reset.

I was driving a new 2013 Hyundai Sonata in a parking area, approaching a parking space for a straight-in parking facing a building. My speed was about 10mph. I brake continuously to slow down and stop, but nothing happened. The car went through the parking space and crashed into the brick wall facade of the building. The air bags did not deploy. The brick wall was not damaged. I had about 5 minor bruises on my right leg, and two below umbilicus (seat belt area). I also suffered from fright and emotional distress. A nearby pedestrian was cut on the ankle by crash debris that projected out sideways from the impact. The debris also scratched a car in the adjacent parking space. My insurance adjustor said that the car was a total loss from the damage.
