So two cells are 400-600mV lower than the rest ? At 50% SoC ? That's massive - I'm surprised the car would drive at all.
Careful diagnosis would be necessary to confirm whether it's two faulty cells (a little bit suspicious that they're side by side) or whether its a faulty LTC chip on a CMU board (since the same LTC chip will be monitoring cells 9-15) but if they are just going to swap the entire traction battery under warranty then that will of course swap all the cells and all the CMU monitoring boards which are bolted directly to the top of the cells, so will definitely fix the problem regardless of whether it's cells or LTC chip.
For a DIY out of warranty repair you'd want to figure out whether it was cells or chip of course.
What does it report for the Ah capacity on the first trip screen in Canion ?
