NHTSA Complaint #11414426 — 2017 TESLA MODEL 3

SHORTLY AFTER PURCHASING THE CAR IT RECEIVED A SOFTWARE DOWNLOAD CALLED EMERGENCY LANE DEPARTURE AVOIDANCE WHICH IS TESLA'S FANCY NAME FOR A LANE DEPARTURE WARNING SYSTEM. I HAVE TAKEN THE CAR INTO THEIR SERVICE CENTERS 3 TIMES TO HAVE IT REPAIRED BECAUSE IT ONLY WORKS <50% OF THE TIME - NEVER WORKS DURING RAIN, SHADOWS ON THE ROAD, AND VARIOUS OTHER NORMAL ROAD & WEATHER CONDITIONS. EACH TIME I GET THE CAR BACK FROM THE SERVICE CENTERS I'M INFORMED THAT THAT SYSTEM IS WORKING NORMALLY. IN LATE JUNE OF 2020 I PURCHASED THEIR BASIC AUTO-PILOT SOFTWARE SYSTEM FOR $2,170 WHICH IS A COMBINATION OF BOTH LANE KEEPING ASSISTANCE (TESLA'S SELF STEERING) AND ADAPTIVE CRUISE CONTROL (TESLA'S TRAFFIC & ROAD AWARE CRUISE CONTROL). THIS SOFTWARE HAS HAD "GLITCHES" AND MALFUNCTIONS EVER SINCE THE PURCHASE. I CONTACTED MARIE MOORE (ASSISTANT MANAGER AT TESLA'S BELLEVUE, WA) ABOUT THE ISSUES AND I WAS TOLD THAT THIS SOFTWARE WAS A "SELF LEANING" TYPE AND WOULD IMPROVE WITH USE. THE FIRST ISSUE WAS THE WHILE DRIVING ON THE FREEWAY WITH AUTO-PILOT ENGAGED THE CAR WOULD VEER RIGHT A FEW TO SEVERAL FEET TOWARD MOST ON & OFF RAMPS UN-NERVING MYSELF & PASSENGERS AS WELL AS GETTING CLOSE TRAFFIC UPSET ENOUGH THAT I WOULD GET HONKED AT OR WORSE. IT GRADUALLY GOT BETTER SO THAT IT WOULD ONLY VEER RIGHT SIGNIFICANTLY LESS. HOWEVER ON 4/19 MY CAR RECEIVED A NEW SOFTWARE DOWNLOAD THAT STATED IT WOULD IMPROVE THE AUTO-PILOT & COLD WEATHER PERFORMANCE. I DROVE THE CAR ON A 140 MILE FREEWAY TRIP ONLY TO DISCOVER THAT THE CAR WOULD RADICALLY VEER RIGHT ON ~90% OF ALL ON RAMPS! TWICE IT NEARLY JERKED THE STEERING WHEEL FROM MY GRIP AND ATTEMPTED TO STEER COMPLETELY OFF THE FREEWAY & ONTO THE ON RAMP. I MADE AN APPOINTMENT AT THE LYNNWOOD, WA SERVICE CENTER ON 4/26 AND WAS TOLD ONCE AGAIN THAT THE CAR WAS PERFORMING NORMALLY & THERE WAS NOTHING THEY COULD DO; & SAME WITH CRUISE CONTROL ISSUES
