2014 LEXUS RX HYBRID Engine Problems

WHILE STOPPED AT A RED TRAFFIC LIGHT, I PRESSED THE PHONE HANGUP BUTTON (BLUETOOTH CONNECTION) ON THE STEERING WHEEL AND THE ENGINE IMMEDIATELY SHUT OFF. I PUT THE CAR IN PARK, FOOT ON THE BRAKE, PRESSED THE START BUTTON ON THE DASH - ENGINE DID NOT START. TRY #4 IT STARTED. MEANWHILE THE TRAFFIC LIGHT HAD GONE THROUGH A FULL CYCLE, THEN RED AND LATE ON THE 2ND GREEN I WAS ABLE TO MOVE THE CAR. CONSIDERABLE HONKING FROM CARS BEHIND ME DURING THE EVENT, BUT FORTUNATELY NO ACCIDENTS OR INJURIES DURING THIS STALL. ON JUNE 17, 2014 I HAD THE CAR TOWED TO KEYES LEXUS MAINTENANCE IN VAN NUYS, CA, MY DEALERSHIP AND THE MAINTENANCE SERVICE I ALWAYS USE. THEY COULD NOT FIND ANY DEFECTS IN THE SHOP OR DURING A LONGRANGE DRIVE, BUT THE DRIVER DID NOT USE THE BLUETOOTH. LEXUS SAID NO SYSTEMIC DEFECTS HAVE BEEN RECOGNIZED...
