Yes, I am very surprised that the entire pack was not replaced. Cells that are made at various times, in various production runs, are not the same as those made under the same day standards. As well, the weak section hurts the sections that were healthy. Thus, I would not trust a piecemeal battery. I actually had no idea that they EVER bothered to replace just a segment.
Your present problem may be corrected by another visit to the dealer...reset? Re-calibration?
But, I would never trust the present Frankenstein battery
*Even Mitsubishi does not do battery sections. I bought a second hand Miev, and as the second owner Mitsubishi honored the battery warranty and replaced the entire power battery. I mean, a second hand Miev owner, and they gave me a complete restart of all cells.
I've been here. I've been there. And I've been in-between.
