I have no idea what happened but I went off road on some basic trails and when i got done I went to the car wash to clean the mud off and when i opened the door it just closes on me instead of staying open when you push it open all the way. does anybody know if something like this is covered under warranty. The dealer is claiming That its not covered.

 

Same part, different issue. Yes, it's covered under warranty.
