I just had an issue with my 2021 model 3 LR my car only has 3600 miles on it. I pulled into QT gas station to make a call and when I put my car in reverse to park it I heard a loud crank noise coming from underneath. I put the car into park and noticed a huge bolt on the ground. I looked under the car and it looked like a suspension part was almost on the floor. Very frustrating considering this is a brand new $52k car.
