Weird behaviour on a few mornings makes me wonder if this is expected. Didn't happen last winter, though. Unpredictable - happens in cold and not so cold days. Actually, come to think of it, this only happens when the regenerative braking is disabled. So it's like I don't have brakes - stepping on mush as I go through the first intersection of the day. This is a very heavy car to slow down.They absolutely return to normal after the frantic 20 second pumping exercises. Anyone else have this? I'm not getting any " car needs service" messages. Should I "work" the brakes before I even start off? This is a P85 with 13000km on the odo.
