2019 Ascent smells like electrical burning AFTER recall service

Has anyone else run into this issue?

We took our ascent in for the heater core recall.

"Inspected wire for burning. No signs of damaged wires tight bolts are tight. Removed old bolts chased threads with no resistance. Installed and torque new bolts."

Had no issues beforehand.

Drove 8 minutes away to pickup something from a cold start and it started to smell. Was a little nervous trying to drive it and get it back home because it smelled strong of electrical fire. Had all the windows open. No visible smoke.

Left a message for the dealership to see what they want to do. Don't want to try and drive it there, so might have to tow.

I want to try and get a visual on where it's happening.

Can anyone describe where I can look? Thanks
