2025 P05AE code

[2025blackout]

Hello all,
Just thought I'd post something that popped up this morning. Recently bought a new white LT midnight edition, AWD, for my youngest daughter and plan on her driving it until she's done with college(still in HS).
It now has around 2200 miles on it.
This morning I took it to work to wash it. Keep in mind it's below freezing here in NW Iowa today. Went to run some errands and noticed it had thrown a CEL. The MyChevy app mentioned something about a cooling or powertrain issue. All the vitals looked fine and I drove it home.
Being someone who does most of my own wrenching, of course I'm gonna dig into it deeper and pulled up a P05AE code, so promptly called the purchasing dealer where I know the service manager well and was told it had to do with the active shutters.
After telling him what had transpired this morning it didn't take long to figure out it was frozen water messing with the active shutters. They did start working again after thawing out, but the code did not clear itself as he thought it would. I cleared the code and it's fine again, but I can see this being a real headache for not only dealer but also owners who live in regions where ice, wet snow, etc is going to mess with these active shutters.
Really like the car so far. It's an LT with the better option package, and of course my daughter loves the features that the DIC and display, but I did get the extended warranty being it's a new model year. I hate to think what just that DIC would cost to replace.

I had to search for what active shutters are and I found this article https://gmauthority.com/blog/gm/gen...echnology/gm-active-aero-shutters-technology/

Toward the bottom, it mentions it has an "ice mode" that the computer does not command them to move if temperatures are below freezing.

I'm inclined to think what happened is since I had it in a 70* shop to wash it, the shutters were open. If not, then when I pulled it outside after drying it off, and after running to another building with it, the shutters froze shut when it was shut down. I'm wondering if just the heat that radiates off the radiator would be enough to thaw it out again. I did notice once I got it home and started it up again after plugging in the OBD reader, they cycled when I started it up. The annoying part was the code did not clear itself.
