Hmmm
Mine releases without problems on flat parking, but sometimes when the car is parked in a parking lot with a slight slope, the braking pads seems to stick to the discs (but that not rust, maybe hill hold assist) and when the car starts driving behind, you can hear a so to speak, chewing sound for fraction of second, did Kenneve see any warning message on meter screen when this happens ?
Kenneve wrote that this happens sometimes.
