NHTSA Complaint #11493779 — 2007 BMW 335I

No past issues with brakes. No warning lights. Went to brake and pedal went to the floor. Christmas tree of lights go off about brake/abs/traction control issue. Press pedal agian, same thing. Press again, and finally get brakes. I was going about 35mph. Luckily I didn't coast through a busy intersection, but if this happened somewhere else, I or others could be dead. I had room to maneuver and avoid an accident. There is no hydraulic issue. There is no leak, fluid is full. Brakes work perfectly fine since this. My guess is that the ABS valves went full open, like it thought all wheels were locked up even though they never even braked. I have not yet had it diagnosed, but the result is irrelevant since this did happen and happened without warning and without a good cause. So it should be reported and tracked. I don't feel the ABS should ever have a failure mode of full open no brakes. Even if the car is old and high mileage (179k).
