2014 Chevrolet Impala Fuel System Problems

TL* THE CONTACT OWNS A 2014 CHEVROLET IMPALA. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE SUDDENLY DECELERATED AND THE VEHICLE WOULD NOT PROPERLY ACCELERATE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE ROCKER ARM AND FUEL INJECTION WERE FAULTY AND NEEDED TO BE REPLACED; HOWEVER, THE PARTS WERE NOT AVAILABLE FROM THE MANUFACTURER. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE LOCAL DEALER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 54,000.

TRAVELING AT APPROXIMATELY 65 MPH WITH CRUISE CONTROL ENGAGED, I PRESSED THE ACC BUTTON TO INCREASE SPEED. I RELEASED THE BUTTON WHEN I REACHED THE DESIRED SPEED (72 MPH) AND THE VEHICLE CONTINUED TO ACCELERATE. THE PACE OF THE ACCELERATION WAS MUCH FASTER THAN NORMAL USE OF THIS FEATURE. (IT FELT AS IF THE ACCELERATOR WAS FLOORED). THE SPEED INCREASED TO BETWEEN 85 AND 90 MPH BEFORE I COULD REACT. I TURNED THE CRUISE OFF AND IMMEDIATELY THE SPEED BEGAN TO DECREASE. THIS OCCURRED ON AN INTERSTATE THAT WAS FAIRLY FLAT.

FUEL PUMP HAS BEEN REPLACED TWICE. 1ST TIME ON NOV 28,2014(12,314 MILES) AND THEN AGAIN ON DEC 28,2015(30,311 MILES). THE ENGINE LIGHT CAME ON 12/04/15(29,448 MILES) AND THE DENTON,TX DEALERSHIP SERVICE DEPT WAS CLOSED SINCE IT WAS A SATURDAY AFTERNOON.HOWEVER WE WERE ADVISED THAT THE CAR WAS SAFE TO DRIVE HOME. LIGHT WENT OFF THE NEXT DAY AND THE WACO,TX DEALERSHIP COULD NOT DUPLICATE THE ISSUE ON DECEMBER 21,2015 (29,848). ENGINE LIGHT CAME BACK ON DECEMBER 26,2015. SAME ISSUE AS BEFORE. ALSO NOTE THE FUEL PRESSURE SENSOR WAS REPLACED ON JUNE 06,2015 (21,408 MILES). THIS VEHICLE HAS BEEN IN & OUT OF THE DEALERSHIP NUMEROUS TIMES BUT ISSUE CANNOT BE DUPLICATED UNLESS THE CHECK ENGINE LIGHT IS ON. NO CODES DISPLAYING. IT SEEMS THAT THE FUEL SYSTEM IS FAULTY AND THE VEHICLE WILL NEED A NEW FUEL PUMP OR SENSOR EVERY 12,000 MILES.
