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.

2003 BMW Z4 Owner Comments

The power steering quit I lost the power steering at approximately 40 mph it was more difficult to steer. When it was taken to the dealer I was informed they had been replacing them free of charge on a case by case basis, but I was out of luck because I was not the original owner. The girl I spoke with said she would talk to her supervisor and see if they could help. I was never contacted back. If my wife had been driving the car at the time the pump failed it definitely could have been a possible accident.

I sometimes notice after my 2003 BMW Z4 2.5I has been parked, it seems as if the tires and steering wheel are misaligned and the car drives to one side as if one tire was flat. This only has happened at lower speeds soon after I start driving, and eventually seems to go away after the car has been driving for a couple minutes. Nothing has been done now to remedy the problem but I plan on giving BMW a call to see what they can do for me. Thank you for your time.
