NHTSA Complaint #11570590 — 2021 KIA NIRO

I received important safety recall letter for NHTSA recall # 23V534. the HCA & or Fuse might need to be replaced . I brought the 2021 Nero to my local Kia dealership, Eagle kia ,Riverhead NY on January 18th. The dealership still has the vehicle & claims that a code came up when they did the diagnostics That requires a part that must be secured to complete the fix for the recall. they claim they are awaiting approval from kia corporate & NHTSA to add to the technical bulletin. But their is no timeframe they have or when this additional part will be available. The dealership has the fuses & Harness for the HCA replacement, but needs this additional part. I asked what the # of this part is or name, but all they would tell me TBT.
