Open the full vehicle complaint log (all categories)TL* THE CONTACT OWNS A 2007 ACURA MDX. THE CONTACT STATED THAT THE BRAKE LIGHT WOULD FAIL INTERMITTENTLY. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHO REPLACED THE BRAKE LIGHT RELAY. THE MANUFACTURER WAS NOT CONTACTED IN REGARDS TO THE FAILURE. THE CURRENT MILEAGE WAS APPROXIMATELY 57,000 AND THE FAILURE MILEAGE WAS APPROXIMATELY 56,800.
AT 62,000 MILES THE LEFT HEADLIGHT FAILED. DEALER INDICATED THAT THE XENON BULB, IGNITER AND CONTROL UNIT HAD ALL FAILED AND BLOWN A FUSE. REPAIR COST WAS APPROXIMATELY $1,000, OF WHICH ACURA PAID 75% AS A GOODWILL GESTURE. NOW, AT 72,000 MILES, THE RIGHT SIDE HEADLIGHT HAS FAILED REQUIRING REPLACEMENT OF THE IGNITER AND CONTROL UNIT AT A COST OF OVER $600. HEADLIGHTS ARE SAFETY COMPONENTS AND IT APPEARS THERE IS A DESIGN DEFECT CAUSING PREMATURE FAILURE OF THESE ITEMS. A BULB IS ONE THING. BUT THE COMPONENTS CONTROLLING THE FUNCTION OF THE XENON BULBS SHOULD OUTLAST THEM IN MY OPINION. WAITING TO SEE IF ACURA WILL ASSIST IN THE COST OF THIS REPAIR. *TR
