John,
You will see from above that I have previously added a comment on this problem too. My car is a late 2018 model and I noticed slight looseness in the pin on my driver’s door stricker.

As a first attempt I tried a non invasive approach. I wicked some Loctite 243 into the small gap around the pin and allowed it to be drawn in by capillary action. Left it overnight and the next morning it was solid. Some months later the pin is still solid, no looseness. Granted, this solution may not be permanent in the longer term and I may eventually have to remove and replace / repair the stricker, but for two minutes effort the non invasive method was worthwhile for me. Passenger side door is okay by the way but of course gets less use and may eventually show some slight play eventually. If it does I will turn to Loctite in the first instance.
