Service Brakes Problems of BMW 545

My passenger side air bag light and seat belt light are both on at all times. The on board computer says fault in passenger side seat belt or seat belt tensioner. Also the back brakes don't work at all but the front ones do. Was wondering if this was a recall matter before I spend thousands to fix the problem.

The contact owns a 2005 BMW 545i. The contact stated that while driving approximately 50 mph, the brake pedal was depressed but failed to respond. After repeated attempts and full bodily force, the vehicle then came to a stop. The vehicle was taken to an independent mechanic for diagnosis. The technician informed the contact that the brake vacuum pump would need to be replaced. The contact referenced NHTSA campaign id number 10v446000 (service brakes, hydraulic) but was advised that the VIN was ineligible under the recall. The vehicle was not repaired. The manufacturer was notified of the defect. The approximate failure mileage was 111,000.

Occurance is very similar to oid 10399328, 10328989 and 10407868. First occurance was in congested traffic conditions at slow speed. The vehicle slowed when brakes were applied normally but did not come to a full stop. Had to stomp on the brakes will exteme force to avoid collinding with the car in front. Problem reoccurred intermitantly 3 time before repairs. Additionally, frequently when foot was on brake when the car was turned off the pedal would forcefully push back against foot. Service on recall for hydrallic power vacuum pump on the booster was performed in January. Dealer said the current problem is not covered under the recall as it is a complete booster failure not the vacuum pump. My perception is that the first recall was not comprehensive enough to address a larger general problem vehicle's booster braking system.

When beginning to drive, the vehicle would slam to the point where I thought I was rear ended. I took the car to my mechanic and he said it was the transmission and the fix was costly. Continues to do this at times and will also do a smaller scale slam when slowing to a stop light or stop sign.

1. The events leading up to the failure - brake loss 2. The failure, how often it occurs, its consequences: this started about 3-4 months ago. I was driving about 25-30mph and had to stop because the light turned red. I stepped on the brakes but my car did not stopped. It felt like I was stepping on a brick but there was no brake pressure. I pulled the e-brake, turned off the car and turned it back on again and it was ok after that. I ignored that issue thinking it was just a phantom issue - just like most electrical issues with BMW's. I don't drive my car everyday - maybe once or twice a week at the most. After a few weeks, I had the same issue again, it happened to me twice. Same scenario - driving about 30-35mph. It is not spongy (I know for sure if it was caused by air on the brake system) - it definitely felt like stepping on a brick, as in literal brick. I thought maybe I have to change the brake fluid since manufacturer recommends replacing the fluid every 2 years. About 2 weeks ago, I was driving at the interstate driving about 70mph, I had to press my brake because a low moving vehicle moved in front of me. I have to press the brake then had the same issue again. I have to drive on the left paved side of the interstate to avoid colliding with the van in front of me. Yesterday, I changed my brake fluid. Went to the groceries to test drive it. Driving about 15-25mph on traffic - had the same issue again. No brakes, no pressure, felt like stepping on a brick. Turned of engine and turned it back on - went back to normal.
