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.

problem #2

Z4 2.5L

  • Manual transmission
  • 86,000 miles


I went to start my car and it wouldn't start. Had to tow it to mechanic. They said they were able to get the car started after hitting the fuel tank with a rubber mallet. They suspect this is because of either a bad fuel pump, or a loose connection. Either way, they told me to take it to the dealership!

Z4 2.5

Fuel pumps failed twice, both times in remote areas of the Rockies. Both problems could not be diagnosed on the computer, but only by manual inspection. The first time the screen on the bottom of the pump collapsed, blocking the pump, second time was an unknown cause.
