WE RECENTLY GOT INTO AN SUA WITH OUR CURRENT TESLA 3. I WAS TURNING INTO MY DRIVE WAY AND I CAME TO A COMPLETE STOP. WHILE I WAS WAITING FOR THE GATE TO OPEN AND WHEN I BRAKED, THE CAR SUDDENLY SPED UP VERY FAST AND I STEPPED ON THE BRAKE AGAIN BUT THE CAR DID NOT STOP. THE CAR WAS ALSO IN HOLD MODE WHEN I LATER CHECKED I NEVER STEPPED DOWN ON THE ACCELERATOR HARD ENOUGH TO REACH THE SPEED OF RUNNING THROUGH 2 CEMENTED METAL GATES. THE AIRBAGS DIDN'T POP OUT AND TESLA'S SENSOR BREAK SYSTEM ALSO DID NOT ACTIVATE. I ALSO BELIEVE THAT THERE WAS AN ISSUE WITH THE COMPUTER SYSTEM OF MY CAR A SHORT WHILE AFTER I PURCHASED MY CAR (APRIL 18, 2018). I WAS DRIVING BACK HOME WHEN THE DISPLAY SCREEN WAS STUCK ON THE PARK MODE FOR THE WHOLE ENTIRE DRIVE BACK. I COULDN'T TURN ON MY SIGNALS, OR SEE MY MPH. EVEN AFTER I GOT HOME, IT WOULDN'T TURN OFF EVEN AFTER TRYING FOR 2 HOURS SO I HAD TO CALL ROADSIDE ASSISTANCE AND SHE TOLD ME A WAY TO RESET THE CAR. ( I HAVE VIDEOS TO PROVE THIS.) THERE HAVE ALSO BEEN INCIDENTS WHEN I AM BRAKED AND WAITING AT A RED LIGHT. I OBVIOUSLY PRESSED ACCEL WHEN THE LIGHT TURNED GREEN, BUT THE CAR WENT INTO PARK MODE AND I WOULD GET STARTLED AND QUICKLY MANUALLY TURN IT INTO DRIVE MODE. THIS HAS HAPPENED APPROXIMATELY 4-5 TIMES IN THE PAST YEAR AND EVEN RECENTLY IN 2021.
