NHTSA Complaint #10875039 — 2016 FORD F-150

2016 FORD F-150 XLT 2.7L ECOBOOST AUTOMATIC MODEL WITH APPROXIMATELY 3,400 MILES. HAD ALREADY DRIVEN ABOUT 4-5 MILES WITH ENGINE ALREADY WARMED UP. DRY WEATHER AND ABOUT 69 DEGREES F OUTSIDE. CAME UP TO STOP LIGHT WITH OTHER VEHICLES AHEAD SLOWED DOWN. CAME TO A COMPLETE STOP AND THE AUTO-STOP FUNCTION ENGAGED AND THE ENGINE SHUT OFF. THE ROADWAY WAS FAIRLY LEVEL. WAITED APPROXIMATELY 20-30 SECONDS UNTIL LIGHT TURNED GREEN. TRAFFIC AHEAD STARTED TO MOVE FORWARD. I LET OFF THE BRAKES AND THE AUTO-START ENGAGED. I CONTINUED TO EASE OFF BRAKES AND ALLOWED THE TRUCK TO ROLL AND IDLE FORWARD WITH THE FLOW OF THE VEHICLES AHEAD. I THEN APPLIED MY FOOT ON THE ACCELERATOR AND BEGAN ACCELERATING WITH THE FLOW OF THE TRAFFIC. ALL OF A SUDDEN, THE ENGINE SHUTS OFF. AT FIRST I DIDN'T REALIZE IT HAD SHUT OFF AND WAS SURPRISED THAT I WASN'T ABLE TO ACCELERATE ANYMORE. THEN I LOOKED AT INSTRUMENT PANEL AND SAW THAT THE SPEEDOMETER WAS READING 17 MPH AND SLOWLY DROPPING AS THE TRUCK WAS JUST COASTING ALONG. MY FIRST THOUGHT WAS THAT MAYBE I HAD ACCIDENTALLY THROWN IT INTO NEUTRAL SOMEHOW, BUT THE GEAR WAS STILL IN "D" AND APPLYING GAS DID NOT MOVE THE TACHOMETER AS IT HAD DROPPED TO ZERO. THEN I SAW THE BATTERY SYMBOL POP UP. THIS IS WHEN I REALIZED THE ENGINE HAD SHUT OFF DURING ACCELERATION, POSSIBLY DURING GEAR SHIFT SEQUENCE. AT THIS POINT THE VEHICLE IS STILL ROLLING ROUGHLY 10 MPH, SO I ENGAGE IT INTO NEUTRAL AND CRANK THE IGNITION AND IT STARTS UP AGAIN. THERE IS TRAFFIC BEHIND ME AT THIS POINT SO I CHANGE GEAR INTO "D" AND AM THEN ABLE TO ACCELERATE NORMALLY UP TO PROPER SPEED. I COULD NOT RECREATE THIS AGAIN FOR THE NEXT 5-6 MILES HOME, EVEN WITH NUMEROUS STOP LIGHTS WHERE I WOULD RECREATE THE SAME AUTO-STOP/START AND ACCELERATE ACTIONS.
