Constant white spots on trim

[2024Yukon]

It's a bad batch of plastic.  I had waterspots on my 2024 Yukon Denali.  Showed up the first time I drove through rain.  For $68.29 all in I had two new ones delivered.  They are super easy to swap, they pop right off and snap back on.  Since then, not a spot in sight and no ceramic coating all the time.  I chose not to deal with the hassle of cosmetic warranty replacement at the dealer, although there is a case for it.

Same for me, started right off - wasn't sure if it was rain or the water from the Tidal Wave car wash I use, but it's terrible and I've fought it to try and get rid of those spots.  I think I'm gonna make a warranty claim - truck is 4 months old with 9k.

 

Chem guys water spot remover seems to get it gone, but it comes back with rain or car wash.  Def bad plastic.  I was wondering if anyone else had the same issue.

 

My truck is Pro trim level, and I think all the plastics and the painted bumper is subpar.  Already have spots in the paint on the painted front end areas as well - thin crappy factory paint and clear.  Quality on this 2024 is def worse than on my 2018 or other prior models.

Same on my 2024 Silverado 2500 LTZ, garage kept never sits outside, definitely defective plastic. The black trim across the windshield base and the plastics pieces on either side.  It is not al all like normal aging of black plastic trim it has gone nearly all white in six months.

If these are made from bad plastic I would like to order new ones. My 25 Sierra has the same white spots and I have tried most all of the chemicals recommended in this post but they come back every rain. What’s the part number for the 2 corner pieces?
