i was driving on the freeway at night and encountered a cardboard moving box in front of me. I decided just to run over it since swerving might have caused an accident. however, the box became stuck underneath the is300 and after making several lane changes to dislodge it, i stopped at the side and took out the box, which was stuck underneath the engine part of the car. my question is whether there might be any potential damage to the car. i did smell something burning while the box was stuck underneath the car and dragging, but not afterwards, and i heard a pop 30 min. after i dislodged the box. thanks for any response. and should i take it to the dealer to check the car out, although it seems to be running fine?
