Low speed complete brake failure. pedal locked & no braking?
My wife spent Saturday in the 328i for her first extended seat time. She told me when she got home that she was upset and distrusting of the car after the brakes acted weird on her in a parking lot. The best that she could verbalize is that they stopped working when she was in a parking lot pulling into a spot, and as a result she wasn't able to stop before the front end scraped over a parking block.
I didn't understand what she was talking about and was preoccupied this weekend at the track in my other car. This morning, I stopped for breakfast at a drive thru and experienced what must have happened to her. While going at low speed stop and go, on two seperate occasions separated by just a few moments, the brakes completely and totally failed on me. Stepping on the pedal gave a completely rock hard pedal, with no to minimal travel at all. (There are no floor mats installed, or anything else that could be stuck under the pedal) The car slowly creeped to a stop, it was like the brakes were just barely applied. Pushing harder gave no additional travel or stopping power, neither did pumping the brakes. I almost tapped a guy ahead of me in the drive thru line when it happened the first time. The second time it happened there was nobody in front of me but it confirmed the odd behavior. After getting out of the drive thru I tried a few more stops and the behavior return to normal long pedal travel/stopping power. I'm sure I don't have to say that this is exceptionally concerning behavior on a brand new car with less than 400 miles on it. Has anyone else experienced anything like this? I tried searching but didn't see any results that seemed to echo this symptom. I will get it into the dealer ASAP.

There was another thread a while back w/ a similar issue but the guy was driving at a moderately slow speed and had to crash into a tree or something.

Yeah couple people complaining about hard pedal, one guy said his brakes failed and he "had to drift into a tree". Your issue seems to be similar to the other guys though, I think they had a booster replaced or something.

Can anyone provide links to the other threads where this has been reported?
It happened 3 more times on my less than 1> mile drive home. Observations: It's always a low speed, multiple use/feathering of the brakes. Once coming out of my office garage and creeping out of the driveway. The second time turning left at a non-arrow green, requiring creeping out into the intersection to turn. After the second occasion, the engine restarted so I thought it may be connected to A.S.S. so I turned it off. I couldn't then reproduce it at a stop sign or pulling into my complex driveway and waiting for the gate to open. Unfortunately, it happened again just a few moments later (with A.S.S. still deactivated) as I pulled into a parking spot and creeped forward while watching PDC display. I am calling my CA at the dealership first thing in the morning. I'm not pleased to have to take a 2 week old car in on a major safety issue that sounds like it may be part of a pattern of similar issues.
