automatic emergency braking activated in error - dangerous

[jessherbie]

I own a 2014 i3 Rex. While moving at 40 mph, my car detected that another car was in front of me and applied emergency braking. There was no car in front of me - it was some distance (at least 50 yards) away and there was not the remotest danger of me hitting it.
This presented a danger as my car jerked some to the right and it was hard to control for a brief moment. The system released on its own. I resumed driving and made it back home without further incident.
My parking brake is malfunctioning also. I plan to take it in for diagnostics at BMW.
To the best of my knowledge, the open recall on the software upgrade has been addressed already.
Anyone else have this happen? What could be the likely cause?

Wow, I'm surprised you got an activation at that high a speed! We're you by chance using ACC? Hopefully the newer software helps. I only rarely get activations at very slow speeds approaching stopped cars (maybe a little too hot) at stop light and stop signs, more often then not in rainy weather.

could have been sunlight hitting camera.

Not had it happen to me, but as it is a camera only system, and ACC can suffer with sunlight (glare) it could be related.

I've had "intervention with braking" at 50MPH - caused by a heavy goods vehicle coming the other way, crossing the central line lane marking slightly. In my case the intervention was not dangerous - but it did surprise me.

It did match BMW's description of how it's supposed to work (i.e. controlled braking, intended to mitigate the likely damage of a collision).

That was almost a year ago now. I've had no recurrence since. It seems to have been an edge-case for the system - perhaps something that BMW had not modeled fully when it was developed.
