2018 Cascadia Issues and Tips - General Use

Regarding the company Cascadia, 2018, auto I have. There are a few issues I was wondering if someone might could help with, but my biggest concern right now is

Is there any common issues of water leaking reported to their tech department. Mine is leaking somewhere, and mostly end up dripping down from the front upper cabinet area, near the windshield, driver side. It takes in water moving or sitting, and tends to dump it in shallow right turns after enough has accumulated. It's almost ruined my GPS. Had to rig some plastic around the quick-connecter area. It was quiet one night when it was sprinking and it seems I could hear a barely discernible "drip drip" up in the front upper cabinet area on the passenger side, well up behind the assembly somewhere. Marker lights seem all tightly screwed down and seals appear good.

It has been to a dealer once already for this issue a few months ago. Not sure what they did (if anything), but it had zero affect on stopping or slowing water ingress.

Can they not "pressurize" the interior cabin and use soapy water on the outside to look for air leaking from areas that should not be leaking? For some reason, I'm not very sure it's the windshield seal, but it could end up being that.

Feel free to use this thread for any other issues you may have. I will likely post some other nuisance issues here again, in the future.

 

Our shop guy said there is some sort of drainage system in the top of the cab to deal with condensation. It's supposed to have a drain hose running down the A pillar. And said those can sometimes become clogged or kinked.

 

All I know is, if it rains for an hour or even less, it will be dripping water in the immediate hours that follow [mostly in turns]
