The contact mentioned that the vehicle was repaired previously under NHTSA campaign id number: 10V446000 (service brakes, hydraulic). The vehicle was taken to a dealer where it was confirmed that the brake vacuum pump was leaking and needed to be replaced. The contact stated that replacing the hose was only a temporary repair that caused future problems to the vehicle. The manufacturer was notified but offered no assistance. The approximate failure mileage was 130,000 and the current mileage was 140,000.

I applied the brakes and they got hard and went to the floor. Brakes would be soft initially and as pressure was continued would get hard and required sustained intense effort to stop the vehicle. This is a known problem by BMW involving the booster and they claim to have inspected vehicle for this problem in 2011 and it did not require being fixed. This was before I bought the vehicle from the dealer. They now refuse to fix the vehicle. This is a safety issue that obviously has not been appropriately addressed by BMW. Sadly BMW prides itself in good brakes but refuses to adequately address a problem they identified. It was listed by BMW as a recall on my vehicle on their website. 10V44660000 they say it has already been fixed. It has not and needs to be addressed because of the serious safety implications.

The contact owns a 2004 BMW 745li. While driving approximately 15 mph, the vehicle stalled. The contact attempted to restart the vehicle with much hesitation from the engine. The power steering light then illuminated and the steering wheel became difficult to maneuver. In addition, the brake power assist warning signal also illuminated. The vehicle was not taken to the dealer for diagnostic testing. The contact referenced two recalls under NHTSA campaign id number: 10V446000 (service brakes, hydraulic:power assist:vacuum) and 04V344000 (power train:automatic transmission:control module (tcm, PCM)) that could have been related to the failure. The manufacturer was made aware of the failures and advised the contact that the VIN was not included in either recall. The approximate failure mileage was 105,000.

The contact owns a 2004 BMW 745I. The contact was driving 45 mph when she applied the brakes and the pedal was depressed to the floorboard.
