NHTSA Complaint #10513213 — 2004 TOYOTA PRIUS

A COUPLE OF MONTH AGO, I THOUGHT I NOTICED THAT THE FRONT DRIVERS SIDE HID HEADLIGHT WAS OFF WHEN THE PASSENGER SIDE WAS ON. I WAS DRIVING IN MY OTHER CAR WHILE A FAMILY MEMBER WAS DRIVING THE PRIUS. WHEN I LOOKED AT THE PRIUS A SHORT TIME LATER, BOTH LIGHT WHERE ON. OVER THE PAST COUPLE OF MONTHS I HAVE NOTICED THAT THE DRIVER SIDE HEADLIGHT HAS BEEN INTERMITTENTLY OFF WHEN IT SHOULD BE ONE. CYCLING THE LIGHTS OFF THEN ON APPEARS TO TURN BOTH HEADLAMPS ON FOR SOME PERIOD OF TIME. THERE IS NO INDICATION IN THE CAR WHEN THE FAILURE OCCURS, AND I AM CONCERNED THAT THIS CREATES AN UNSAFE SITUATION WHILE DRIVING AT NIGHT. WHILE TRYING TO DETERMINE IF THIS IS A KNOWN PROBLEM, I CAME ACROSS OWNER CHAT GROUPS WHERE OTHERS WHERE COMPLAINING ABOUT THE SAME PROBLEM. I ALSO READ THAT THERE MIGHT BE AN NHTSA INVESTIGATION INTO SIMILAR COMPLAINTS. I WOULD LIKE TO KNOW IF AN INVESTIGATION HAS HAPPENED AND IF SO, WHAT WAS THE OUTCOME? *TR
