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.

Just purchased this car from a private owner. Didn't notice but the passenger side door will not unlock by either using the key fob or the central locking/unlocking switch inside. Did a google search and found that the GM-5 board needs to be replaced. I also heard that this GM-5 can cause failure on other functions with the car - wipers, lights etc. The car is 10 years old but only has 36,000 miles on it. This part should not fail so quickly.

The steering binds at almost any speed. I noticed it when driving straight forward. When a correction in direction is made the wheel binds until greater pressure is applied. It seems the problem is requiring even more pressure for the correction. I called bmwna and they told me they have heard nothing about this problem. I am in fear for my safety as well as others around BMW's Z-4 2004.

Water gets into the battery compartment through the rubber grommet that carries the main battery cable from the trunk to the front of the car. The battery compartment is a well that also houses the car stereo amplifier. Amplifier was sitting in about 2 inches of water causing the circuit board to short out and catch on fire.

2004 bmx Z4, steering became unresponsive while driving at highway speeds. Over correction to regain control narrowly avoiding traffic and center divider. At slower speeds it felt like there was no steering fluid in car. Very difficult to turn. BMW dealer had replacement steering column in stock it took 2 days to replace at a cost of $2942.02.
