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.

When you turn on the turn signals the 4-way emergency fashers are activated, causing a confusing situation for other drivers who cant tell what you want to do. This is an intermittent problem.

I own a GMC Envoy LX 2004. When I put my left turn signal on the hazards turn on. This does not happen everytime, so it is very hard to repeat. This is very dangerous because I sometimes can not signal. I do not have time to stick my hand out side to let the people near me now I am turning. Also the right turn signal sometimes just does not work. It is also random.
