Does anyone else do this?
I just got home from a drive and it's 80F outside and going up to 84 today. Just out of curiosity, I opened my engine bay and it was hot! The carbon fiber surrounds were very hot where they attach to the rails but not so bad where they are open and vented. I am going to start leaving the hatch open 8" or so to help get the heat out. I just wonder how long the carbon fiber pieces will last getting so hot. They are covered with reflective insulation on the bottom side but still very hot on the top. It will only get hotter here in the coming weeks. I think the engine bay lights turn off after about 10 minutes, so I'm not worried about the battery.

i recall folkls with C7s opening the hood to let "Hot Air Out!" GM selects materials than can stand the heat! They have instrumented the engine compartment at high ambient temps. Recall my friends son, and Engineer at GM at the time, testing AC in Death Valley. Why worry!

Per Google AI:
Death Valley is the hottest place on Earth. Summer daytime temperatures routinely exceed 120°F in the shade, with recent summers averaging well over 104°F overall. Ground temperatures can reach a blistering 201°F.
