NHTSA Complaint #11395642 — 2008 TOYOTA PRIUS

PRIMARY HEADLIGHTS RANDOMLY GO OUT WHILE BOTH PARKED AND DRIVING DOWN THE ROAD. SOMETIMES BOTH AT THE SAME TIME. TURNING THEM OFF AND ON AGAIN MANUALLY RESETS THEM TO WORK AGAIN. THIS SEEMS LIKE A HUGE DESIGN FLAW AND MAJOR SAFETY HAZARD, SINCE IT LEADS TO DRIVING IN THE DARK WITHOUT HEADLIGHTS. REPAIR SHOPS WANT $100S PER BULB TO REPLACE HID BULBS THAT SEEM TO NOT ACTUALLY BE BURNED OUT. THE DESIGN CHOICE FOR HID BULBS THAT EXHIBIT THIS TEMPORARY FAILURE MODE SEEMS TO BE A FUNDAMENTALLY FLAWED ENGINEERING CHOICE COMPARED TO OTHER, MORE RELIABLE TECHNOLOGY SUCH AS LEDS. NO EXISTING RECALLS WERE FOUND WHEN SEARCHING THE DOT.GOV WEBSITE FOR THIS ISSUE.
