No it didn’t smell , I had washed the carpet , opened the lids and let everything drain , then got called out to work out of town for a month , so the lid had been shut for 30 days, my Z9 is a 2015 model and I’ve washed the carpet regularly since buying it new , guess it was just the perfect conditions for the mold to growObviously, this is some kind of mold. How long since you popped the hatch? Maybe you need to install a fan system? Did it smell?
Thanks for that info , I think I will try that too. I used soap and water to remove the mold then used a very worn scotchbrite pad and bleach water to kill it and remove the stains from the handles.Here is a mitigation step you can do. I think I am going to do this myself.
