Brakes suddenly became very hard to engage. It took quite a bit of force to bring the car to a complete stop. A mechanic informed me that the brake booster system had failed and that BMW had a recall for the system - 10V-466. I called BMW warranty and informed them of the reason for my call as well as the VIN. They told me that there were no outstanding recall notices for my vehicle. While no one could tell me when, the fact that there were no outstanding recall notices on this vehicle apparently indicating that the correction on the car had been made. After a lengthy debate about what this meant and why BMW said they had no more responsibility for the issue, I asked to speak to a supervisor. I got sarah (employee #7716), an escalation supervisor. Very nice but essentially told me there was nothing she could do, that BMW was not responsible for this matter and there was no one that she could escalate me to. If the correction, as spelled out in the recall notice was in fact made, it did not work. The actual language used in the recall notice under correction states as follows: ¿the updated brake booster vacuum supply line with fluid check valve is to be installed in all applicable vehicles to eliminate future contamination.¿ (the emphasis is mine) I had ESC save all of the parts and they have confirmed that in fact the brake booster was contaminated with oil which caused the membrane to fail. To me, this means one of two things: 1. the updated booster vacuum supply line with fluid check was never installed in my vehicle; or 2. the BMW solution to the problem was faulty. As for the brake booster vacuum supply line, it appears that the line was replaced at 97K miles in August of 2013. So what good did that do? it failed again, (I have all of the parts) in less than 5 years. See documentation attached.

Rollaway: Certain model year 2005 through 2008 7 series equipped with the comfort access option and manufactured from August 23, 2004 through July 24, 2008 have an electronic key and an electronic connection between the gear shifter and the transmission (shift-by-wire) that automatically shifts the transmission to park when the driver presses the start/stop button to shutdown the engine. If the engine start/stop button is pressed 2 or 3 times within a short time interval, the system may shift the transmission to neutral rather than park. If using the electronic key (comfort access mode), there would be no protection from the ignition interlock that prevents key removal if the vehicle is not in park.

The contact owns a 2006 BMW 750li. The contact stated that the vehicle was taken to a dealer for a manufacturer recall for the brake system. The dealer indicated that they provided the remedy, but the contact stated that the brake pedal was extremely difficult to depress. The contact had to place both feet on the brake pedal to ensure that the vehicle had come to a complete stop. There were no warning indicators each time the brake system failed. The vehicle was also taken to several independent mechanics for diagnostic testing. The recall repair remedy provided no solution. The manufacturer was notified. The recall information was not provided. The failure mileage was not available.

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.

While stopping, the brake pedal became extremely hard and went to the floor, just barely avoiding a catastrophe. This happened with no warning whatsoever, and this could have been a multiple death accident. I contacted BMW of na and they informed me that my VIN number was not included in the recall. I clearly should be, because I know I am not the only one this problem.

Brake peddle appear to resist depression, and braking becomes difficult or impossible. The resistance feels like a control system resisting, and preventing the peddle from being depressed. But it could possibly be a failure of power assist, but it feels like a hard, but slightly spongy resistance, like a hydraulic system closed a valve down stream of the brakes. The issue began abruptly 5 days ago, from no indication at all of an issue, to an abrupt issue in full effect. Now it is consistant, and very repeatable. When braking to a stop from over 20 mph, the brakes work normally down to ~10mph. Then between 10 and 7 mph, the brakes feel like they are pushing back, if not strongly resisting depression. Braking is difficult and dangerous. Take caution.

. while driving I came to a intersection I depressed the brake pedal but the brakes did not respond. I continually applied pressure to the brake pedal until the brakes responded. The vehicle was taken to an independent mechanic for diagnostic testing where the mechanic replaced the front brakes and rotors. 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.
