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.

2010 BMW Z4 Owner Comments

problem #1

Feb 052010


  • 1,500 miles


Car is a new (11 /21/09) BMW Z4 with less than 2,000 miles. When driving in Suburban traffic at approximately 45mph, driver signaled for a right hand turn at an intersection without a traffic light. When brakes were applied, there was virtually no stopping power. Unable to slow for the right turn, driver proceeded to the next turn while applying all of the physical pressure she could muster, which finally slowed the car top the point it could be turned and stopped. If this brake failure had occurred when there was stopped traffic, an accident would have certainly occurred. The problem was a catastrophic failure of the power brakes hydraulic booster. Additionally, no warning light ever came on before, during or after the brake failure. The BMW service department said that there are warning lights for low fluid and low pads, but not for booster failure, which is unbelievable.
