i bought a silver 2012 SE with 40k miles that i thought was in perfect condition since the cells were all within 5mV when fully charged to 16 bars. But it would only go about 25 miles before hitting turtle with 2 bars showing. Cell #27 was 0.6 volts below all the rest, and #20 was 0.4 low. Charged it on L2 and let it balance--Full 16 bars and 36 RR, and all cells within 5mV again. Then i drove it 10 miles and it used 6 bars. Do some more testing tomorrow.
So does this seem like it would qualify for a new pack under warranty even though it charges fully? The seemingly defective cells only manifest as the pack gets drawn down. i can imagine the dealer thinking this was normal wear and tear degradation that is not covered.
