Vehicle slams into first gear upon deceleration and "slips" if you take your foot off the gas pedal and then accelerate immediately, as in traffic conditions. When transmission gets in stop and go traffic it will slam into gear before acceleration occurs. Car was at BMW dealer for seven days with all software upgrades that dealer suggested were performed and still same problem. No call backs to date. Spoke with BMW of North America and they referred me back to dealer. Unwilling to admit there is a problem with the transmission even though they have issued intercompany tech. Bulletins regarding the exact problem.

- Ontario, CA, USA

- the contact owns a 2006 BMW 750. The vehicle has a transmission that should automatically shift the vehicle to the park position when the start/stop button is depressed. The contact depressed the start/stop button and noticed that the vehicle started to roll forward approximately 2 seconds after the engine lost power. He was able to depress the brake and stop the vehicle. The contact stated this also occurred approximately 2 weeks later. The contact parked and exited his vehicle, upon his return the vehicle rolled backwards approximately a hundred feet and crashed into a lamppost. The road conditions were clear on both occurrences and the vehicle was parked on a flat surface. The parking brake was not engaged. The dealer stated they are unable to diagnose the failure. The current mileage was 7,000 miles.
