When in a coasting mode(no accelerator use) car will apply braking all on its own and will not release braking till car comes to a full stop. no objects or cars are anywhere in front of the car when this happens. has happened twice while going around medium radius curves in the road. very dangerous to us and the other cars behind us because we get no indication this is going to happen. this has happened a couple of times. the last time is indicated below.
