2017 Nissan Pathfinder Body & Structure Problems

TL* THE CONTACT OWNS A 2017 NISSAN PATHFINDER. THE CONTACT STATED THAT THE LIFTGATE FAILED TO OPERATE AS DESIGNED INTERMITTENTLY. THE CONTACT ALSO STATED THAT WHEN THE LIFTGATE STARTED TO OPEN, IT WOULD THEN IMMEDIATELY CLOSE INDEPENDENTLY WITHOUT WARNING. THE CONTACT TOOK THE VEHICLE TO WELCH NISSAN (2505 S OLIVE ST, PINE BLUFF, AR 71601) WHERE THE MECHANIC WAS UNABLE TO DIAGNOSE THE VEHICLE. THE VEHICLE WAS REPAIRED HOWEVER, THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND REFERRED THE CONTACT TO NHTSA FOR ASSISTANCE. THE FAILURE MILEAGE WAS UNKNOWN.

ENGINE HOOD VIBRATES AT SPEED AT ABOVE 55 MPH. I CAN SEE IT MOVES UP AND DOWN FROM DRIVER SEAT.

ON FEBRUARY 10, 2018, WE BROUGHT HOME A NEW PUPPY. WE WANTED TO CALM OUR CURRENT PET DOWN SO I WENT INSIDE MY HOUSE TO LET HIM OUT TO USE THE RESTROOM AND CALM HIM FOR THE INTRODUCTION. IT WAS A COLD NIGHT SO MY 7-YEAR-OLD DAUGHTER AND HUSBAND WERE IN THE BACKSEAT UNBUCKLED WITH THE HEATER ON. NOBODY WAS IN THE FRONT SEAT AT THE TIME. THE CAR WAS RUNNING AND I HAD THE KEY IN MY POCKET IN OUR HOUSE. ABOUT 7 MINUTES LATER I HEARD A CRASH. IN MY MIND, I FIGURED MY HUSBAND WAS MOVING THINGS IN OUR GARAGE BUT WHEN I WENT OUTSIDE, THE CAR HAD ACCELERATED UP MY DRIVEWAY AND INTO MY GARAGE. IT CRASHED INTO MY FREEZER, AND IF THE FREEZER HAD NOT BEEN IN THE WAY IT WOULD HAVE CRASHED INTO MY HOUSE. NISSAN FLEW AN ENGINEER DOWN FROM TENNESEE AND HE RAN A REPORT ON HIS COMPUTER AND FOUND NO FAULT. I ASKED IF THEY KNEW WHY IT HAPPENED AND IF THEY TOOK THE VEHICLE APART TO LOOK FOR CAUSE AND THEY SAID: "NO, WE WERE NOT LOOKING FOR WHY ONLY IF THE COMPUTER SHOWED AN ERROR." I ASKED FOR THE REPORT AND THEY STATED THAT THE REPORT WAS PROPRIETARY AND REFUSED TO RELEASE IT TO ME. IT SEEMS ODD THAT THEY WOULD NOT RELEASE THE REPORT IF NISSAN IS NOT AT FAULT.
