Vehicle had indication of passenger mat sensor failure. Spoke to dealership with no luck on coverage.

"fault in passenger restraint system affecting airbag, belt tensioner or belt force limiter" vehicle was towed to a local BMW vehicle on monday , june 10, and I have been waiting to hear something/anything from BMW factory ever since.

The mechanic found contamination in the brake booster and notification of NHTSA campaign id number: 10V446000 (service brakes, hydraulic:power assist:vacuum) the vehicle was towed to the dealer. The dealer changed the valves & then told me I had to pay for diagnostic cause the breaks weren't working which I did paid $149 plus tax. After the diagnostic the technician stated that the brake booster would have to be replaced. Per the recall, the brake booster could become contaminated over time due to the recalled failure. The manufacture advised me that the repairs would not be covered. *tr

When pushing on the gas, the vehicle would stall, RPM's would shoot up, and would take 3-10 seconds to re-gain any power before the vehicle would begin to accelrate. Also once coming up to a stoplight or stop sign, the vehicle would feel as if someone had slammed into the back of me possibly jerking into gear. Spent countless times at the dealership with them giving me the run around, replacing random parts before replacing the entire transmission and still the vehicle continues to have issues. *tr
