I was driving out on a slightly rocky dirt road when I hit a major dip and had to swerve a bit to make a U-turn. Right after that little maneuver, I heard a thunk and saw something fall off the back of the car. I did not get any warning lights come on, and I drove another 30 miles to reach the town where I am staying for the night. The car seems to be driving completely fine, but I still had a quick look underneath. It looks like it came off a missing plastic section in the undercarriage near the back. I did not see any vital looking mechanical pieces missing from the area, just that one section of plastic. Please tell me what exactly this piece is and how concerned should I be about driving another long distance tomorrow😑😂 #CarTrouble #MechanicHelp #AutoRepair #CarAdvice #Cars
