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.

2001 BMW Z3 Owner Comments

problem #3

I am driving as normal and then the car begins to have problems shifting and the transmission indicator light comes on. The owners manual tell you to pull over and shift the car into park and then apply the parking brake and turn the car off and then back on. It seems to temporarily correct the problem but it still occurs on days when the air temp. Is high. I have had the car on the diagnostic a number of times with no cure. As far as I know there are no recalls on the transmission or ECU. But this could be a major problem at high speeds on the highway or in city traffic if the car stalls or locks up BMW 2001 Z3 2.5I (steptronic shifting)
