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.

2006 BMW Z4 Owner Comments

This report concerns a safety issue with a 2006 BMW Z4 with a 3.0 engine and automatic transmission. The vehicle has an intermittent problem that began earlier this year. The vehicle will begin accelerating without depressing the accelerator and will sometimes maintain a constant speed when the foot is taken off the accelerator. It will accelerate well past 100mph without stopping. The three ways that stop the sudden acceleration is to 1. apply the brakes, 2. put the gear selector into neutral, or 3. tap the ┐off┐ position on the cruise control lever. Cruise control has never been utilized when the vehicle has experienced this unintended acceleration. There are no floor mats in the vehicle that could impede the functioning of the accelerator. This vehicle has been taken to the dealer for service on multiple occasions. A tech working on the vehicle stated that he believed it was a cruise control sensor, but the shop foreman determined there was nothing wrong. BMW of North America inspected the car and have stated that ┐they will stand by their product and that no defect exists.┐ I have provided video documentation of this issue to BMW.
