ON NOVEMBER 1, 2019, I WAS SLOWLY BRAKING AND START TURNING RIGHT INTO MY DRIVEWAY ON THE 2013 TESLA MODEL S. I FELT A SURGE OF THE VEHICLE AND 1 SECOND LATER, THE VEHICLE LANDED ON TOP OF THE STAIRCASE OF MY HOUSE ENTRANCE AND DRIVEWAY. I DID NOT PRESS ON THE ACCELERATOR AT ALL WHEN I SLOWLY TURNING INTO THE DRIVEWAY.THE VEHICLE SPED ON ITS OWN FOR ONLY A SPLIT SECOND. I CALLED TESLA ROADSIDE ASSISTANCE. THE REPRESENTATIVE CONTACTED ME AND DIRECT ME TO A REPAIR SHOP AND HE TOLD ME THAT HE WOULD HAVE THE VEHICLE'S INFORMATION TO BE SENT TO THE ENGINEERS TO FIND OUT WHAT HAPPENED. I HAD MY VEHICLE TOWED BUT TO REPAIR SHOP BUT TESLA SUPPORT TEAM HAS BEEN IGNORING ALL MY CALLS AND EMAIL. MY VEHICLE WAS CONSIDERED TO BE TOTAL LOSS BY MY INSURANCE COMPANY.
