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.

I left my BMW in the sun all day and now my locks wont work. Many resources link this problem to the GM5 which controls the lighting and locks. Bad locks can be a safety and security issue on parked cars but also for moving cars as children may open vehicle doors in traffic.

My BMW Z4 which is still under warranty has defective headlights and the dealer refuses to repair them. BMW used an inferior type of plastic which is clouding over and preventing the headlights from working correctly. Please recall these vehicles so that BMW will repair the lights and make it safe to drive at night again.
