NHTSA Complaint #10819863 — 2011 FORD EDGE

(ON MULTIPLE OCCASIONS )MY 2011 FORD EDGE UPON ACCLERATION THE VEHICLE LOSES THE ABILTIY TO ACCLERATE - SHUDDERS AND THE CHECK ENGINE FLASHES OR STAYS ON. SUPPOSEDLY COULD NOT FIND THE "CODE" THAT CAUSED IT. I HAVE HAD THE VEHICLE INTO 2 DIFFERENT DEALER SHIPS - ONE REPLACED THE TRANSFER CASE, THE OTHER THE CATALYTIC CONVERTER AND IGNITION COILS- TO THE COST OF OVER 600.00 ON A USED CERTIFIED VEHICLE. LESS THAN A FEW DAYS LATER SAME ISSUE - BACK TO DEALER SAID IT WAS A LOOSE WIRE. I NOW DRIVE THE VEHICLE VERY TENTATIVELY AND HOPE I DON'T HAVE TO ACCELERATE QUICKLY.THE VEHICLE PERSISTS IN THE ABILITY TO NOT ACCLERATE QUICKLY ( USUALLY AT 55 MPH OR HIGHER )WITHOUT THE ENGINE LIGHT FLASHING OR STAYING ON. IT ALSO SEEMS TO HAPPEN MOST FREQUENTLY ON QUICK ACCLERATION --ON RAMP OR GETTING UP TO FREEWAY SPEED . IT IS VERY DANGEROUS AS THIS USUALLY HAPPENS GETTING ON OR OFF THE FREEWAY OR STAYING UP WITH TRAFFIC, ONCE THE LIGHT GOES ON THE VEHICLE SHUDDERS AND WILL NOT ACCELERATE TODAY IT WILL BE 3 MONTHS FIRST VISIT WAS OCT 29 MILEAGE WAS 68000 AND HAS HAPPENED UP TO TODAY MULTIPLE TIMES AND MILEAGE IS NOW 74000 THE CHECK ENGINE LIGHT IS ON AGAIN BACK TO FORD DEALER AGAIN TOMORROW.
