2012 Toyota Sienna Lights Problems

THE PASSENGER SIDE HEADLIGHT TURNS OFF INTERMITTENTLY. IT WILL TURN ON AGAIN IF YOU TURN THE HEADLIGHTS OFF AND BACK ON, BUT THEN WILL GO OUT AGAIN. I HAVE READ ONLINE ABOUT MANY OTHER TOYOTA OWNERS, SPECIFICALLY THOSE WITH PRIUSES, BUT ALSO SOME SIENNAS, HAVING THIS PROBLEM. DEALERS DON'T KNOW HOW TO RESOLVE IT - MINE WANTS TO REPLACE THE BULB FOR CLOSE TO $500, BUT CAN'T GUARANTEE THIS WILL RESOLVE THE PROBLEM AND THE BULB IS APPARENTLY WORKING, JUST NOT ALL THE TIME. THIS IS A SAFETY ISSUE TO HAVE A NON-WORKING HEADLIGHT. *TR

TL* THE CONTACT OWNS A 2012 TOYOTA SIENNA . THE CONTACT STATED THAT WHILE TRAVELING 30 MPH, THE HEADLIGHTS FAILED TO FULLY ILLUMINATE THE ROADWAY. THE VEHICLE WAS TAKEN TO THE DEALER.THE MANUFACTURER WAS CONTACTED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGES WERE 400.
