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.

My husband and I were driving down a town road in our community on cape cod on a clear day. Suddenly we heard what sounded like a gun shot. It scared the living daylights out of us because it was so loud, like an explosion. We pulled over into a parking lot to investigate what had happened. The sunroof of the car had completely exploded with shattered glass streaming off the back of the car. Thankfully, we had the canvas part of the sunroof closed. If left open, we would have had glass coming down onto our heads and laps. This, for sure, could have caused an accident. The sound alone, was terrifying! it seemed to explode outward, and there was nothing that seemed to hit the roof. I did some investigating about tempered glass and realized that it is not so rare of an occurrence for this to happen because of the inclusions of nickel sulfide often found in tempered glass. It seems that nobody at our dealership has ever heard about this. It appears, after investigating cases online, that it has happened more often than anyone realizes. It is truly a hazard. What can be done" if you like vehicles with sunroofs, don't drive with the canvas open unless you completely open the sunroof to the air. Or, don't buy another vehicle with a sunroof. Or, change the way sunroofs are made??"

Driving down the road pretty much in the middle of nowhere in Colorado, clear blue sky, no traffic and my sunroof deflector spontaneously shattered into a million pieces. No impact, no nothing! temperature around 65 degrees, no weather. Taking it to dealer upon return as I was 200 miles away from home when it happened. Unknown if Scion/Toyota will cover's obviously defective!
