Our 2020 limited has acquired a musty smell and I can't locate the source of it. A water jug fell over in the truck 2 months ago and saturated the trunk liner and the majority of water went into the spare tire well. I removed everything in the trunk, removed the liner, spare tire ect. Removed all the plugs and drained the water and then towel dried the sump and trunk. Nothing was wet to the touch and I left the truck and windows down for 2 days to dry out. Put everything back and all was good for about 2 weeks, then we began to get that musty smell. I removed everything again in the trunk, I removed folded down the rear seat back, removed the rear seat cushion all floor mats and I could not feel anything damp or when sticking my face on the floor, seats, trunk, etc, cannot nail down a particular area. We live in Georgia and have parked the car outside in the hot sun with the windows down. There is no place that is damp that I can find, but when you open the car doors, a musty smell hits you. Does anybody have any ideas as to where I could be missing? The HVAC line drains like it should, I removed the filter and smelled it, and it is fine as I recently installed it a month or so ago. I am going nuts trying to find the origin of this smell. Any ideas? Thanks

My 2020 Limited has a musty smell coming from the A/C system for about a minute after starting. I’ve asked the service department and they brushed it off as normal.
What you describe sounds very different, but I thought I’d mention it here anyway. A thought: Is the sunroof draining properly?

Since you likely run the AC quite a bit in hot, humid Georgia, it's a good practice to manually turn off the AC button a couple of minutes before you arrive home and run the fan on high to warm and dry the evaporator coil. This helps prevent mildew and the common musty smell that results when the coil is often left wet when the system is turned off.
If you only run the AC on the recirc option, run it taking air from outside for awhile. I can smell immediately the cars that only run the AC on recirc and it gets deep into the summer.
Could be other things, but perhaps you only run the AC on recirc mode?

Check the firewall harness on the passenger side. There is a large rubber grommet with the harness thru the firewall that either comes loose or rodent's chew through or pull out ?
