NHTSA Complaint #11570429 — 2022 TESLA MODEL 3

Something occurred with the steering, automatic braking, or lane keeping assistance on [XXX] at approximately 6:35am while I was driving my 2022 Tesla Model 3 Long Range North in the carpool lane just south of [XXX] in Sandy Utah. The roads were a little slick so was proceeding cautiously at around 65 MPH when the car turned to the left slightly, then immediately to the right, which caused it to do a 180 degree turn in the same lane, I wasn't sure what was going on as the car felt like it was driving itself. Before I knew what was happening, the car then veered to the East across three lanes of traffic while driving backwards, it then stopped just as it was struck in front of the wheel on the front drivers side by a two trailer semi-truck which spun the car around. Luckily I was conscious so could slowly limp across the last couple lanes to the right side of the road where I called 911. I've driven all kinds of cars in all kinds of conditions and in many countries in the nearly 32 years I've been a licensed driver and have never lost control of a vehicle, I'm sure the steering or lane assist was trying to intervene so must've somehow inadvertently caused the crash! It's only through the grace of [XXX] that I'm still alive to tell about it! Also, none of the airbags went off even though the impact from the semi was very jarring!
