I truly appreciate the risks Nissan took in bringing this car to market and can't understand why they booby-trap themselves and EVs in general by doing the absolute minimum regarding this continuing fiasco with the '11/'12 battery pack.
As Nissan, the first thing I would do internally is acknowledge how much harm was done with bullsh*t marketing stunts like
this. (see Perry at 01:00) As late as 2012, Mark Perry was giving interviews saying "you'll have
70-80% of capacity left after
10 years". Put a stop to that plus the "100 miles of range" nonsense which are truly harmful misrepresentations, aka lies, about a product. In earlier interviews, >80% at 5 yrs > 70% at 10 yrs was his standard line. I don't think anyone on this forum, even from temperate Calif, expects that kind of pack performance now.
Then I'd start to repair the damage by:
1) pro-rating capacity loss for anyone's pack that didn't live up to the bullsh*t spouted by official Nissan mouthpieces at every venue. If at anytime before 5 years, my pack falls below "80% at 10 yrs" number, it's fully replaced.
2) offering to buy-back (from non-leasers) their Nissan LEAF at the residual value established for leasing when the car was purchased. I think, in 2011, that was around $17k for 36 mo, < 36k mi.
3) pricing a replacement pack no later than November 2013 when portions of the warranty begin to run out and people need to figure out if they want to extend or not.
4) fixing the battery pack life issue with either TMS or chemistry. Honestly present what the expected improvements will yield and warranty accordingly.
