Drivers Door Stop Thingy Rubbing

I am not sure what this part is called, but it appears to be the thing that limits the door from opening to far.

It's rubbing on the window track when closing the door and I cannot figure out why. I opened up the passenger door panel and this part does not touch the window track (or make an irritating noise).

There is no apparent evidence of damage or misalignment. I tried loosing the mounting bolts to realign and had no luck. Any ideas? Anyone else have this happen? Thanks in advance!

 

Anybody know how this part functions?

 

The only thing I found is something similar to a Toyota Matrix.

It is bent. Replace it.

 

id have to agree. on a jeep its called a door check. sometimes they break the metal inside that plastic piece and slide out and make popping noises. get a new one and call it a day
