Same for me. I ordered an Ioniq 6 on the 19th Dec 2023, picked it up 26th Jan 2024. Absolutely no trouble from my local Hyundai dealership, Ryders Of Warrington, they were very helpful and nothing was too much trouble (Nice one Steve). Could have had the car sooner than the 26th Jan but that was my decision to pick it up on that date.
Could just be Hyundai customer Service working as it should.
