| Description of the problem | The vsc system is enabling while driving and making a turn on an otherwise normal road. When it enables, it applies the brake and sounds a repeating alarm. The system applies the brake while i am attempting to make a turn, and this makes me feel unsafe, as if i have temporarily lost control of the vehicle while making an otherwise benign maneuver. The repeating alarm does not turn off until i have turned the wheel to the opposite direction from the initial turn angle. This means if the turn is slow, the alarm will sound for the entire distance of the turn. |
