NHTSA Complaint #11190300 — 2016 FORD EXPLORER

WITH THE CRUISE CONTROL SET AT ~78 MPH ON AN INTERSTATE HIGHWAY THE AUTOMATIC TRANSMISSION APPEARED TO SHIFT INTO A LOW GEAR CAUSING THE VEHICLE TO SUDDENLY DECELERATE AND THE ENGINE TO REV TO MATCH THE SET SPEED. THE VEHICLE DECELERATED FROM 78 TO ABOUT 40 AS IF I HAD SLAMMED ON THE BRAKES. AFTER STOPPING AND TALKING WITH MY DEALER HE RECOMMENDED TO CONTINUE AS NO WARNING LIGHTS OR INDICATORS APPEARED ON THE CAR. I CONTINUED ON THE ROAD AT A MUCH REDUCED SPEED. AFTER A SHORT DISTANCE THE VEHICLE AGAIN SELF SHIFTED TO A LOWER GEAR WITH THE ENGINE RPM'S SHOWING APPROXIMATELY 3000 AT ABOUT 55 MPH. DEALER IS INSTALLING A NEW TRANSMISSION BUT CAN NOT IDENTIFY WHAT CAUSED THE VEHICLE TO SHIFT GEARS ON ITS OWN.
