| Description of the problem | While driving at 55 mph highway speed and curving gently to the right, the vsc system on this minivan evidently picked up a false indication of a slip in the vehicle's traction. This caused the car to automatically apply the brakes on the left side, pulling the van's direction from right to left, and slow the car quickly from 55 to 35 mph, with vehicles behind me quickly closing in on the rear end. Within seconds the automatic braking ceased and i was able to reaccelerate back to normal highway driving speed. The engine was not stalled in the process. |
