NHTSA Complaint #11084028 — 2017 FORD EXPLORER

VEHICLE SURGE ON FIRST ACCELERATION AFTER STARTING THE ENGINE. SURGE - THE VEHICLE EXPERIENCES AN ACCELERATING LUNGE FORWARD AND THEN STOPS FOR ABOUT TWO OR THREE CYCLES (STOP/START, STOP/START ETC.) IT IS UNEXPECTED AND UNCONTROLLABLE UNTIL IT SUBSIDES WITHIN 20 TO 30 FEET. THE DEGREE OF THE UNEXPECTED ACCELERATION IS EXCESSIVE WHEN COMPARED TO THE SLIGHT APPLICATION OF THE GAS PEDAL CONDITIONS - HAPPENS ONLY AFTER THE FIRST STARTUP OF THE ENGINE, IN WARMER WEATHER WHEN THE "CHOKE" IS NOT REQUIRED. EXAMPLE: START ENGINE, BACK OUT OF GARAGE, PLACE IN FIRST GEAR, ACCELERATE SLOWLY FOR THE FIRST TIME. THIS IS WHEN THE SURGE IS EXPERIENCE. IT DOES NOT HAPPEN WITH EVERY STOP/START CYCLE DURING NORMAL DRIVING, LIKE STOPPING AT A TRAFFIC LIGHT. IT HAPPENS ONLY AFTER STARTING THE ENGINE, AND GOING FORWARD FOR THE FIRST TIME. THE PRIMARY PROBLEM IS THE DEGREE OF THE UNCONTROLLED, OSCILLATING ACCELERATION RELATIVE TO THE SLIGHT AMOUNT THAT THE GAS PEDAL IS APPLIED. IT IS NOT ABOUT AN OVERLY SENSITIVE ACCELERATOR PEDAL. IT ABOUT THE ENGINE SURGING, THEN DYING OFF, THEN SURGING AGAIN.
