2009 LEXUS LS Power Train Problems

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...

AFTER AN OIL CHANGE, USING FULLY SYNTHETIC OIL PER STERLING MCCALL LEXUS OF HOUSTON, THE LEXUS LS460 SHOWS HESITATION IN ACCELERATION. AT LOCAL ROAD AND AT SPEED OF 15 MPH, I TRIED TO ACCELERATE AND PUSHED GAS PEDAL TO FLOOR, THE ENGINE RPM REACHED MORE THAN 5000 BUT THE CAR DID NOT ACCELERATE AS EXPECTED. WHILE IN THEORY THE ENGINE POWER REACHES PEAK OF 386 HORSE POWER AT 4200 RPM. IN ONE WORD, THE ACCELERATION IS NOT LINEAR TO THE PUSH ON GAS PEDAL AT ALL. FEELS LIKE THE ENGINE POWER DOES NOT CORRESPONDS TO THE GAS PEDAL TRAVEL DISTANCE, AS IT SHOULD. AND IN CRITICAL SITUATIONS, THIS FAILURE TO ACCELERATE AS IT SHOULD COULD CAUSE PROBLEM OR ACCIDENTS. A GOOGLE SEARCH SHOWS THAT MANY OTHER OWNERS HAVE THE SAME EXPERIENCE. MAYBE LEXUS SHOULD LOOK INTO THIS AND HELP FIX THE PROBLEM. THANKS, *TR

TL* THE CONTACT OWNS A 2009 LEXUS LS. WHILE THE VEHICLE WAS PARKED THE CONTACT NOTICED THERE WAS FLUID LEAKING FROM THE FRONT END. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING AND THE TECHNICIANS STATED THE TRANSMISSION HAD A HOLE ON THE SIDE WALL THAT ALLOWED TRANSMISSION FLUID TO LEAK. THE TRANSMISSION WAS REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND WAS UNABLE TO PROVIDE ASSISTANCE. THE VEHICLE WAS REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 200.
