Sweet that they got some kind of response in the way of 'codes', even if those data points are confusing back at Kia. May have been they were able to haul a GDS system along for the ride which provides as much info to a Kia tech as they could possibly have about performance. Interesting that your 'power control module' is coming direct from engineering. That could mean either a) some new beta code to see if it resolves the issue, or b) some logging software that they're hoping will catch a specific condition that just 'codes' won't pin down.
