NHTSA Complaint #11322245 — 2009 LEXUS LS

I PURCHASED MY 2009 LS460 IN 2017 AT LEXUS OF HUNTSVILLE, AL WITH 115K MILES. IT BEGAN HAVING POOR ACCELERATION 1 MONTH AFTER I PURCHASED IT. I WENT BACK TO THE DEALER AND EXPRESSED MY CONCERN. THEY ASKED ME TO START USING PREMIUM GAS FORM THE SAME STATION. NOTHING CHANGED AND 3MO LATTER I MOVED TO INDIANAPOLIS AND HAD MY LEXUS SERVICED AT TOM WOOD LEXUS OF INDIANAPOLIS. I ASKED THEM TO DO A FULL DIAGNOSTIC FOR REPAIRING THE NOW DANGEROUSLY LOW ACCELERATION. TOM WOOD CHANGED AND CHECKED FUEL FILTER FUEL LINES FUEL INJECTORS AIR INTAKE MASS AIRFLOW AIR FILTER REFLASHED ECM COST ME 2 SEPARATE VISITS, 10+ DAYS IN A LOANER VEHICLE AND $800+ AND THE ISSUE BEHIND WHAT WAS CAUSING THE LOW ACCELERATION WAS NEVER FOUND. SO I FILED MY FIRST COMPLAINT CASE WITH LEXUS CORPORATE AND THEY DENIED MY CLAIM IN THAT IT WAS NO LONGER UNDER THEIR POWERTRAIN WARRANTY. DESPITE MY EFFORT TO SIMPLY REQUEST AND STATE THAT I PURCHASED MY LEXUS AT A LEXUS DEALER AND IT HAS BEEN MAINTAINED BY A LEXUS DEALER. I OUGHT TO BE ABLE TO RELY ON LEXUS (ESPECIALLY AN LS ON OF THEIR HIGH END DESIGNS) TO BE OF REASONABLE QUALITY, FIT FOR SAFE USE AS AN AUTOMOBILE. THE LIABILITY FOR DEFECTS OF THE ENGINEERING OF THE INTERNAL MECHANICS AND ANY FUTURE WRECKS OR INJURIES CAUSED BY THE ENGINEERING DEFECT IS LEXUS' LIABILITY. JUST TRYING TO HAVE A SAFE VEHICLE FOR MY FAMILY. WELL THAT GOT ME NOWHERE WITH LEXUS. NOW MY JOB HAS ME LINING IN LOUISIANA AND I TRIED A SECOND TIME AND TOOK MY LS460 TO PRICE LEBLANC LEXUS OF BATON ROUGE. THEIR SERVICE TEAM WAS FANTASTIC AND THEIR TECH LET ME KNOW THAT THIS IS A KNOWN ISSUE WITH LEXUS AND THAT I'D NEED TO REPLACE ALL CYLINDER HEADS AND VALUES. TOTAL COST BEING $13-15K. THAT IS MORE THAN THE VALUE OF THE VEHICLE. I HAVE FILED A SECOND COMPLAINT AND REPAIR REQUEST WITH LEXUS CORPORATE AND AM BEING TOLD THE SAME LINE AS BEFORE. NOT THEIR PROBLEM.
