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.

2009 BMW Z4 Owner Comments

The car has stalled multiple time when coming to a stop. In some instances I did not have to come to a complete stop such as crossing a divided highway, just slowed significantly. As I went to accelerate through the intersection the engine had stalled and I was stuck in the middle of the intersection with no power. Car starts right back up each time but you must stop to place the car in drive(automatic transmission). Nearly hit by oncoming traffic on 3 separate occasions. Dealership was able to replicate, sold me a $400 battery as the fix. Car stalled on the way home from dealership. Returned the car but they could not replicate and since the instances did not produce a fault code they could do nothing. Car continues to stall which makes it a safety hazard. There are 100's of post on BMW forums with the same issue but BMW claims to have no knowledge of the issue. Someone needs to step in and make them address the issue. This is not the known battery cable issue, that was replaced per recall.
