BMW F30 3-series Brake Failure

I thought my experience was an isolated incident and hope it doesnt happen again, but the rise in occurrence by fellow forumers leads me to think that this is a real cause for concern and might be a factory defect in our cars


Known Cases of brake failure

I personally experienced this, while creeping foward in a carpark exit i stepped on the brakes but it was rock hard and didnt respond. Luckily it was an upslope and gravity stopped the car before i rear ended the guy in front






Serious but non-fatal accident

Has anyone else experience something like this? I am very surprised to see that on a brand new f30 the brakes would act like this. Any comments would be appreciated thanks!
Other cases

I'm extremely worried and I can't drive it at all right now. Any recommendations? This is my first BMW, and I'm almost started to regret my purchase.

He told me there is another 328 XI that has the same problem sitting there for almost a month waiting for the parts to come from Germany. I expect the same to my car. FYI, my car was also built in February and I received it two weeks ago.

I was racing an E60 M5 (V10 sound was ) and I was on his tail the first 50 meters but he then quickly flew away. Anyway, I hit around 220 km/h (140) mph before trying to slow down as I had to make it onto an off-ramp. This was slightly downhill. I hit the brake pedal, NOTHING, itīs rock hard and no bite. I was already turning but quickly realized I wasnt gonna make it so a split-second decision was made and I just kept goin straight on the freeway. My speed was now around 180 km/h (110 mph) and then quickly decreasing as the car was just rolling. A few sesconds later, brake function restored. Had it bit initially I would have had no problem decelerating enough to make it, Iīve tried them before and know how good they bite. I got the Euro M Sport brakes (same as the M Performance Brakes), what do u guys have?

And another question to all of you that experienced this: Has it happened on some occasions or has it been a constant issue? To me, it happened this one time...

EDIT: And if its the cylinder-thing, would I notice anything now or can it still function properly?

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.


BMW if you're reading this . . . please do something about it and issue a recall, if necessary.

Do chime in if you have a similar incident
