NHTSA Complaint #10507520 — 2008 LEXUS LS460

AFTER THE VEHICLE HAS AN OIL CHANGE, THE CAR WILL (INTERMITTENTLY) HESITATE TO ACCELERATE. THIS IS ESPECIALLY DANGEROUS WHEN YOU ARE TRYING TO MERGE INTO THE FREEWAY OR SIMILAR OCCASIONS. WHEN ATTEMPTED TO DEPRESS THE GAS PEDAL WITH EXPECTATION THAT THE CAR WILL RESPOND AND ACCELERATE AS NORMAL, THE ENGINE JUST REVS UP AND THE VEHICLE DOESN'T MOVE ANY FASTER THAN CURRENT SPEED. THIS WILL CONTINUE FOR 5-10 SECONDS THEN IT KICKS IN. THIS DELAYS IS VERY DANGEROUS WHEN YOU WANT TO GET OUT OF HARMS WAY (ACCELERATE TO MERGE INTO FREEWAY, PASSING ETC). THE PROBLEM IS INTERMITTENT AND WILL GO AWAY BY ITSELF WITHIN A FEW HUNDRED MILES (BUT WILL COME BACK SPORADICALLY). ALL THIS HAPPENS BY ITSELF AND CANNOT BE REPRODUCE AT WILL. HOWEVER THE OCCURRENCES OFTEN HAPPEN AFTER OIL CHANGE OR SO (BUT NOT NECESSARY). I HAVE BOUGHT THE CAR INTO THE LEXUS DEALERSHIP(S) TO FIX (YES 5 TIMES AT DIFFERENT DEALERSHIP) BUT THEY CANNOT FIX THIS ISSUE. *TR
