Owner reports
Selected complaints filed with NHTSA by 2006 BMW 750li owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2006 BMW 750LI. The contact stated that while driving at an undisclosed speed, several unknown warning lights illuminated. Additionally, there was oil leaking onto the ground and also onto the engine. The vehicle was taken to an independent mechanic who diagnosed that the brake vacuum pump needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA. The failure mileage was approximately 129,000.
Brake vacuum pump booster has failed due to contamination even after brake booster supply line was replaced in December, 4, 2010. When vehicle is in motion, the car loses power to brakes, brake pedal feels hard and vehicle takes 20-30 ft longer to brake even if pushing down with maximum force. This caused vehicle to take an infinite amount of time to stop, which resulted in car nearly running into another vehicle when issue occurred. Luckily I swerved off highway unto median. This issue can result in death or catastrophic accident as brake booster vacuum pump is affected in such a way that brake power is 50% less than normal, low to negligible brake power means car does not stop normally, it takes more time to stop, which can lead to death from rear end collisions, freak accidents and even running into persons or objects when parking.

Spoke to a rep who dismissed my vehicle complaint because the VIN # does not fall under the luxury package therefore not included in the recall. 2nd issue..the vehicle brakes when applied does not stop. Twice it's happen when I tried to slow or stop resulting in scaring me half to death and near accidents. …
