2014 Lexus ES Fuel System Problems

WHILE ACCELERATING FROM A STANDING STOP OR ACCELERATING WHILE CHANGING LANES, THE VEHICLE WOULD HESITATE BEFORE THE ENGINE ENGAGED. WHAT WAS MORE FRIGHTENING WAS WHEN THE VEHICLE WAS OPERATING ON THE ROAD AND THERE WAS A NEED TO CHANGE LANES, YOU PRESSED ON THE GAS THEN THE VEHICLE WOULD TYPE TO ENTER TEXT HESITATE FROM 1 TO 3 SECONDS. YOU LITERALLY FOUND YOURSELF IN NO MANS LAND, AS THE VEHICLE FAILED TO RESPOND AND YOU FOUND YOURSELF CAUGHT STRADDLING TWO LANES AND THE VEHICLE VIRTUALLYSTOPPED ACCELERATING. THIS SITUATION STARTING OCCURRING MORE AND MORE WHEN I OR JANE LANES,MADE RIGHT AND LEFT HAND TURNS, OR ACCELERATED FROM A STANDING STOP. T THE VEHICLE HESITATION, WHILE ACCELERATING, IS FRIGHTING AND DANGEROUS. IT SEEMS TO BE GETTING WORSE. WE MADE AN APPOINTMENT WITH NEWPORT LEXUS TO HAVE THE VEHICLE'S STALLING CORRECTED AND SERVICED. ON OCTOBER 21, 2015 WE TOOK THE VEHICLE TO NEWPORT LEXUS AND EXPLAINED THE PROBLEM TO THE SERVICE ATTENDANT. THE VEHICLE WAS EXAMINED AND THEN ROAD TESTED BY CHRIS PERET, NEWPORT LEXUS CHIEF MECHANIC. AFTER THE ROAD TEST, THE VEHICLE DID HESITATE AT TIMES WHEN HE ACCELERATED THE VEHICLE. THE CAUSE IS HOW THE FRONT WHEEL VEHICLE IS DESIGNED.THE PROCESS AND HOW THE VEHICLE ACCELERATION PROCESS WORKS ON A FRONT WHEEL DRIVE VEHICLE; THE GAS PEDDLE WHICH IS IN THE FRONT OF THE VEHICLE SENDS A SIGNAL TO THE ENGINE WHICH IS IN THE FRONT OF THE VEHICLE, THE ENGINE SENDS A SIGNAL TO THE COMPUTER WHICH IS IN THE REAR OF THE VEHICLE, THE COMPUTER THEN SENDS A SIGNAL TO THE ENGINE AND THE VEHICLE THEN ACCELERATES. HE EXPLAINED THE PROCESS IS ALMOST INSTANTANEOUS AND THERE IS ONLY A VERY SLIGHT HESITATION. IF THIS LAST COMPONENT OCCURS YOU COULD GET A LONGER DELAY BEFORE FROM THE TIME YOU DEPRESS THE ACCELERATOR TO THE TIME THE VEHICLE ACTUALLY ACCELERATES (1 TO 3 SECONDS).
