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.

2004 BMW Z4 Owner Comments

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 2004 Z4 door on the passenger side would not open. The inside and outside handles would not open the door. Shortly afterwards the drivers side door handle began to fail intermittently. I was locked inside my vehicle without the ability to get out.
