“While driving at night the dim head lights go off for no reason,this happens every two days or so , so I have to drive with bright lights (which blinds on coming traffic) on for about six or seven miles before the low beams start working again. Dealership can't seem to duplicate problem, so nothing has been done yet.”
NHTSA complaint #10208477, filed 2007-11, 50,000 miles“At night while driving the low beams headlights turn off and after a few minutes turn back on. The high beams work when the lights go out and we have to turn them on to have headlamps. The daytime running lights don't seem to be affected by the problem during the day. Problem happens only at night.”
