Car dealers sometimes change the oil in cars when they get them regardless of miles.
Very dirty or wrong viscosity oil can cause failure of the VVT valves, not necessarily mucking the timing. However, that will cause the CEL and Traction and disable the A/C.
What Misfire?
Now the A/C is disabled? That's different from "compressor cutting on, and almost immediately back off".
The fan will run after shutdown if the coolant temp is high, thus my question.
Note the DRL wiring in the attached schematic. 2 fuses to the left side then the right side.
There is a common point in the A/C compressor and left headlight circuits; G109 at the left strut tower. Link:https://www.chevyhhr.net/forums/how-...cations-56504/
