Hi,
So yesterday we had a couple of inches of snow and I live in a very hilly part of the country. Overall the car handled it well but it did scare the living daylights out of me a few times.
Going down a steepish hill, very slowly with regen on full, just feathering the throttle to control the regen/speed and without warning, the regen just cuts off! Car starts gaining speed rapidly and the only method of slowing it down was the friction brakes! Slid to a halt at the bottom of the hill, up against a dry stone wall. Luckily the only damage is a scratch to the mirror casing. Scary as hell. Without engine/regen braking, friction brakes alone are not great in snow!
Got the regen back on by turning the car off and back on but the same thing happened again a couple more times. I then realised I could actually make it happen. Low traction surface, steepish downhill, feather the throttle and sure enough the regen 'fails'.
Battery on the car was about 60% so this wasn't due to high state of charge preventing regen! It really is dangerous; I was just very lucky I never met anything coming the other way on the occasions when I was hurtling out of control. Car will be going to the dealer next week for them to investigate because this surely can't be by design.
Anybody else had anything similar happen?
Be careful in the snow folks!
