Had a dealer appointment today to get a tire patched, rear tag light replaced and have this window trim cracking documented. I showed the service advisor the cracking and explained that I just wanted it documented in case it got worse. I wasn't really interested in having the whole assembly replaced this early on in ownership, especially since I just paid to have the windows tinted.
Later another service advisor came out to tell me the car was ready. They had patched the tire, the tag light LED apparently decided to work today (literally hasn't worked a single day in the last 5+ months), and they have a new window on order...wait what? I told her I didn't want it replaced, just documented as I just had the windows tinted, and would rather wait to have the new unit installed at the end of the warranty period as to extend the length of time before another failure (they all crack). She looked at me and said, "no sir, you don't have to leave your car here. The part is on order so you can take your car home with you today". She wasn't getting it, so I just said "ok" and left it at that.
Good to know they were quick to warranty the part. At least I have it in writing so down the road, hopefully they won't fuss about it.
