I've owned my M3 LR AWD now for over a year and love it, but I've finally worked out a strange (minor but potentially unsafe) bug with the non-AP cruise control. I've been able to replicate this behaviour several times now.
When I am travelling up a hill (around 5% incline) at around 50-60 km/h (haven't tested at higher speeds), and I engage cruise control, the indicator on the screen shows that it has engaged at that speed, but when I release the accelerator, the cruise doesn't "grab", so I have to keep my foot on the accelerator for the entire length of the hill. When the incline tapers off to a more level road, cruise then takes over. There's no "push-button" method of cancelling the cruise that I'm aware of, other than tapping the brake.
It's annoying mostly, but carries a potential risk. For instance, if the hill was long enough that I had forgotten CC was engaged since I'm still pedal driving, it may suddenly accelerate to the established CC speed. Or if my pedal driving speed had dropped by the time I reached the crown of the hill, it again will accelerate unexpectedly once the road levels off.
Is say this is a bug, not a feature. In those instances, it would be better if the Cruise Control just didn't engage at all, putting a notification on-screen.
I searched the forum but couldn't find anyone else mentioning this issue.
