Cylinder head high temp

[nnnnnn]

Yeah Op, I am not a mechanic expert but I will say this based off your post. You need to go over anything unusual in your maintenance routine with this car since it has such low miles. Did you change oil at a place you normally don't change oil at? Anything unsual? Maybe type of oil?

Your car is too new to be experiencing water pump and head gasket failures or even thermostat problems. But yeah don't keep driving it until you find the cause.

Were you cruising, heavy traffic or driving hard? And pp1 or not? Mine is a pp1 and I used to see 224°ish max when I was NA. And yeah some really hot days I would never go over 212° and some cooler days (like 90s) it would shoot up. If I was on e85 it rarely went over 205° in the summer. Some guys see 230s° way more often. My logic is don't beat it too hard once it hits triple digits outside and when I do drive it hard I let it cool down once my CHTs get in the high 220s. Boosted that seems to be about 3 consecutive pulls when it's in the 90s. I'm at 84k miles now so whether I'm right or wrong it's worked so far!

It's mostly the stupid grille shutters that non PP cars have that lead to these hot ass temps. Just today I was testing something, and with the A/C on, my temps didn't go over 187 (60 degree ambient temps). With A/C off, the shutters close for efficiency at light cruise and it worked its way up to 212 pretty quickly. Given A/C in itself is a heat load, it shows how much just choking off the airflow does for CHT. The car doesn't really have a reason to care though. CHT is 10 or so degrees above coolant temp. It doesn't even run the fans on low speed until 216F (coolant temp).

I am going to throw this out there.
Going by his location, and no first hand knowledge of the area other than media and photo's.
If this car has the grill shutters, the dusty, sandy roads kicking up the dust could have locked up the shutters and limited air through the radiator.
Or the radiator fins are caked up with dirt.
