NHTSA Complaint #11444088 — 2020 TESLA MODEL 3

I was trying to avoid a car parked on the side of highway on my right going between 45 to 55 miles an hour and slightly steered the car to the left, and the car swerved back and forth at the slightest steering wheel movement as if skidding in the snow. The road was dry (no rain) but the steering was not stable and the car ended up hitting a truck on the left. It caused a very serious accident and we are lucky that there was just a major car damage and no one was hurt. The steering seems to be uncontrollable and loose, and causes major swerving if one has to steer away at a high speed.
