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.

Z4 6-cyl

  • 7,000 miles


2011 BMW Z4, purchased new with approximately 7K miles. Started to feel vibration when I put on brakes around 5K mile mark. Vibration lasts 1-2 seconds. Happened 20 times so far. I was driving today, 7000K mile mark, and the engine failed and died. Like somebody just turned it off. Luckily I was on local street so I just came to a complete stop. This is very dangerous! then I restarted the car and it came back to life and ran like normal. Took it to dealer and dealer said nothing was wrong. Something is wrong if your car dies while you're driving!!

Whenever slowing down to a near stop, the engine will randomly stall. This can occur at anytime, but is more likely to occur when the outside air temperature is in the 90's or above (it will stall in cold temperature as well, but not as often). The engine temperature at the time of the stall is always completely normal, the car is not overheating in anyway. It is also more likely to occur in "sport mode". this issue only effects BMW E89 3.0 automatics. An automatic should never stall. Once the engine stalls you are forced to stop the car in order to restart to move. This issue is occurring world-wide. I have taken the car to the BMW dealer in austin, tx to look into this issue. They stated that there were no error codes present in the computer. The check engine light is not on. I had a BMW shop foreman drive with me and we reproduced the engine stall as we approached a stoplight. He stated there were no BMW service bulletins about this issue. Other E89 Z4 owners have taken their car in for service at BMW dealers in California, Florida and Texas and in all cases the BMW mechanics found no reason for the engine stall and do not have a fix. Random engine stall when slowing is an extremely dangerous issue. I consider this vehicle (E89 3.0 automatic) to be unsafe and unreliable in hot weather. Serious injury can occur if a car randomly shuts itself off as it is being slowed. Over the past 6 months, this has happened to me at least 15-20 times.
