NHTSA Complaint #11568059 — 2023 TESLA MODEL Y

I used to have a 2021 performance y (the 2021 had none of these issues), and purchased a 2023 in early October. My current milage is 2,783. A few weeks into owning this car I could feel something hitting the cabin floor in varying situations. Initially I thought it was a road debris, but it was only at lower speeds. I should only be able to hear road debris and not feel it in the floor. I have come to believe that the car has loose structural bolts. I have a crease/dent in the roof pillar (passenger rear above door). It is an almost impossible spot to hit without a scratch or breaking the glass, and it would take an exorbitant amount of force to bend that pillar. I now have singled it out to torsion moments like entering a driveway or ramp. I believe this twisting could potentially compromise the battery pack and lead to fires in wet conditions.
