NHTSA Complaint #11643450 — 2022 KIA EV6

I took my 2022 Wind AWD EV6 into Bob Johnson Kia for the required SC327 recall service on Feb 17. I was informed that the service would not be performed because they were having too many problems with critical failures after performing the service on other cars. Specifically, they said they had 7 EV6s that died within weeks of performing the SC327 update, 4 of which were still in their back lot waiting for new ICCU assemblies. They recommended to wait until Kia sorted out the quality issues surrounding the SC327 update. This seems highly suspicious since it's a required recall service. I'm aware that Kia has a design problem with the ICCU and has mishandled service support from the beginning, but I need to understand my course of action and how you recommend I handle this situation.
