ON MARCH 1, 2017 I WAS STOPPED AT AN INTERSECTION. AFTER PROCEEDING STRAIGHT THROUGH THE INTERSECTION AND REACHING A SPEED OF APPROXIMATELY 10-15 MPH I HEARD AN ALERT IN MY CAR, AND SIMULTANEOUSLY HEARD CARS BEHIND ME SOUNDING THEIR HORNS. I QUICKLY LOOKED UP INTO THE REAR VIEW MIRROR AND SAW THAT THE TAILGATE OF MY CAR HAD OPENED WITHOUT WARNING WHILE I WAS IN MOTION, CAUSING MY DOG TO FALL OUT OF THE BACK. THIS OCCURRED AFTER TRAVELING FOR APPROXIMATELY 6-8 MILES WITHOUT EVER RECEIVING A DASHBOARD ALERT THAT THE TAILGATE WAS OPEN. THERE HAVE BEEN ELECTRONIC ISSUES WITH THE CAR SINCE I PURCHASED IT NEW. SOMETIMES THE CAR WON'T RECOGNIZE THE KEY FOB AND THE DOORS WON'T UNLOCK, OR THE CAR WON'T START AND I GET AN ALERT THAT THERE IS NO KEY DETECTED (WHEN IT IS IN THE CUP HOLDER MERE INCHES FROM THE PUSH-BUTTON IGNITION START.) TWICE THE FASTEN SEAT BELT ALERT HAS LIGHTED AND CHIMED, WHEN THE DRIVER HAS THE SEAT-BELT FASTENED AND THERE ARE NO OTHER PASSENGERS IN THE CAR. OFTENTIMES THE TAILGATE WON'T OPEN WITH THE KEY FOB OR BY UTILIZING THE OUTSIDE BUTTON - ON THIS PARTICULAR DAY IT TOOK ME SEVERAL MINUTES OF FUSSING WITH ALL THE CONTROLS BEFORE I COULD GET THE TAILGATE TO OPEN AT ALL. THIS WAS THE FIRST TIME THE TAILGATE OPENED ON ITS OWN. THE ONLY OTHER THING THAT I RECALL ABOUT WHAT HAPPENED THAT DAY IS THAT AS I WAS GOING THROUGH THE INTERSECTION MY RIGHT FRONT WHEEL DIPPED INTO A POTHOLE WITH A SIGNIFICANT JARRING.
