Ripple door trim

Hey guys new(to me) 2018 M4 convertible CP owner here - technically a week ago I bought it and drove it from the Sacramento area back to Denver via AZ/NM. Mostly a fun drive but ran into snow and ice on the way back.

Anyway, the car is in pristine shape except for one thing that I can find. Both the seller and I do not recall the trim on the drivers door separating from the plastic beneath creating this terrible looking bubbly rippling effect. It would have been super obvious to me when checking over the car the way I did; even my wife noticed it within 30 seconds of her seeing it for the first time.

So what I’m curious about is if anyone has seen this happen before. I already have a visit to the shop scheduled to get it replaced under warranty, but it bugs me that this happened. The only thing I can think is that the cold temperature one night must have caused an expansion contraction issue between the plastic and the black chrome-type material on top. See photos below.

Oh, an I threw in a shot when I was able to put the top down and crank the heat a little.

This has to be an unique case cause I've never seen this before.

That's crazy. It looks just like someone left protective plastic film on it (like my stainless fridge).

Well, I’m glad to hear it isn’t a common thing (this far), otherwise I’d be more worried about the other side or even the future replacement doing the same thing. Temperature shouldn’t do that, but I don’t know what else would have.

I can say positively there is no protective film. Rubbing your finger down the length of it the ripples move under the pressure, but you can feel it is fairly thick.

It was most definitely not left outside with top down... That said, are you really suggesting that a convertible can't sit outside in the sun with the top down?? Come on, it's a convertible and that's what people actually do with them. I will probably never leave the car alone for more than a couple seconds with the top down, but to each their own.

The car is at the dealer currently getting the trim piece replaced under warranty. Hopefully I'll get it back tomorrow before weather gets worse again.

Same issue in my F82 M4 2018.

I live in Korea and found that same thing on the left door after 6 days parking outside in a very cold weather.

And I found another guy who has same issue in Korea too.

I collect these cases and will show my service adviser soon.

I would tend to think it is a batch issue where the trim parts weren't prepared correctly before getting the metalized chrome treatment. What month year were your cars manufactured? I'll look mine up and edit this post once I know.

Edit - my '18 car was made 7/17.

I suppose you could always wrap them in something. Apparently the "chrome" they use can be scratched, so I'm not sure hire much that would be different if you wrapped in some of the fake CF stuff I see people use on various things. Probably look pretty cool in CF. To be honest, I'm not sure why I haven't seen this be a thing that's out on Aliexpress.

I would imagine the dealer had to remove the entire door panel to replace the trim price. I'm sure they didn't replace the entire panel on mine, just the trim piece.

Had my car in for something else last week and brought this issue up to the service advisor. BMW ended up replacing it under warranty. I did mention this forum thread, not sure if that swayed them. Might also be the service advisor. When I first brought it in just for that trim piece, the service advisor said they can only do a 'good faith' repair and that I would have to pay half. Now, with a different advisor, it get taken care of completely free of charge. I don't know if this will help anyone, but I figured I'd just post the update, just in case.
