THE MANUFACTURERS WERE NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 320,000.
I CALLED MY LOCAL LEXUS THREE TIMES PRIOR TO JUNE, 2012 REGARDING LIGHTS SUDDENLY ILLUMINATING ON THE DASHBOARD. I HAD A RECURRING ISSUE WHERE THE CHECK ENGINE AND VSC WARNING LIGHTS WOULD ILLUMINATE. EACH TIME THE CUSTOMER SERVICE AGENT TOLD ME THAT THE LIGHTS WOULD GO OFF WHEN I REFUELED. THREE TIMES THE LIGHTS DID GO OFF (AFTER SEVERAL DAYS), BUT ONCE I HAD TO HAVE THE DEALER RESET THEM. THE MOST RECENT OCCURRENCE RESULTED IN THE DEALER TELLING ME I NEEDED THE AIR FUEL AND AIR FLOW SENSORS REPLACED, A REPAIR WHICH COST OVER $750.00. AS AN ASIDE, EVERY TIME I CALLED TO INQUIRE ABOUT THE LIGHTS BEING ILLUMINATED MY CAR WAS UNDER WARRANTY AND NO REPAIRS WERE SUGGESTED. AFTER THE WARRANTY EXPIRED I WAS THEN ADVISED THAT THE SENSORS NEEDED TO BE REPLACED. *TR
