Open the full vehicle complaint log (all categories)THE BRIGHT /DIM HEADLIGHT CONTROLLER HITS THE BACK OF THE STEERING WHEEL IF THE STEERING WHEEL IS IN A POSITION DURING A RIGHT DIRECTION CURVE IN THE ROAD. THIS HAS CAUSED THE SWITCH TO CATCH IN BETWEEN SETTINGS AND THE HEADLIGHTS TURN OFF. AN EXAMPLE OF THAT USE WOULD BE GOING AROUND A CURVE AND NEED TO TURN BRIGHT LIGHTS OFF DUE TO ONCOMING TRAFFIC. TO GET THE HEADLIGHTS BACK ON, THE BRIGHT / DIM SWITCH HAS TO BE ACTIVATED AGAIN. THIS VEHICLE WAS PURCHASED NEW BY MYSELF IN 2003 AND HAS BEEN A PROBLEM FOR AS LONG AS I CAN REMEMBER SINCE OWNING THE CAR. I FORGET ABOUT THE PROBLEM WHEN I GET HOME SO NOW I FINALLY REPORT IT IN 2018. THE PROBLEM APPEARS TO BE A FACTORY DEFECT BECAUSE THE SWITCH AND STEERING WHEEL ARE NOT DAMAGED. THE INFORMATION ABOUT WHEN THE INCIDENT HAPPENED IS ONLY THE LAST INCIDENT.
