Sorry for your trouble. Are there any similarities to when these leaks occurred on both vehicles? (Pressure washer, automated car wash, etc.) or was it just during a rain storm? Trying to gather details so I can look for the same type of leak during certain times.
Both occurred after Rain storm. And both in the same location just one on the driver side rear seat (cx30) the other on the passenger side rear seat (cx50). I believe it’s coming from either the door (faulty seals) or B pillar (sunroof related).
remove the plastic trim and put your hand under the carpet, the top felt completely dry. Only reason I did this was because when I went to pick up my cx30 from the dealer this morning (was told the water leak was fixed) the carpets felt dry, but when I removed the plastic trim there and pulled up the carpets, they were soaked underneath.
I came straight home and tried the same with the CX50, all felt dry but was soaked under the carpet in the rear on the passengers side.
my best advice is take a hose to the pano sunroof then each door and see if there is any point of intrusion. I went through NY lemon law in 2018 with Ford over a leaking f150. I hope both vehicles are resolved without having to go through that nightmare again!
