I recently noticed that my front fender liner was broken which exposed the internal parts (see attached image). There was no impact to the car as I am the only person driving this. I have not even hit a hard bump or pothole, AFAIK in last few weeks.
So I thought this must be a manufacturing defect, where the fender liner has fallen off by itself. But my dealer's body shop guy thinks, something might have hit it at an angle to break it off or it might be an act of vandalism. Now, given that I have been driving on paved roads only and I have no known car vandalists' -
Could this really be a manufacturing defect?
What are the odds of something hitting a fender so hard to break it off on paved roads?
If I chose not to replace the fender, could water get into the engine and damage it?
