Who knows ... but it seems to be a similar story to what we hear is happening in other markets. If anyone's Kona gets the "OK" rather than a new battery I hope they offer some compensation for a year of being limited to 90%.
From the same "The Driven"
article:
"It is worth noting that if your Ioniq or Kona falls outside these dates, your vehicle is not affected by the recall – and in fact may have been made in a different factory altogether that opened after March 2020."
What different factory? They must be referring to the supply of cells. I'm getting the impression that they failed to record the manufacturing source of each individual cell when building the packs. I can't imagine any "check" that would detect the type of defect we understand is the issue.
