True enough, and I passed this question along. As it is, there would be a 3-year bumper-to-bumper warranty, a 5-year battery capacity warranty, and an 8-year battery power output warranty. That's enough to make someone's head spin.Yes, they hear "8 year warranty" as in the 8 year battery defect warranty all EVs have and assume it covers capacity (when it clearly doesn't if you look into the details).
I understand this concern, but to be fair, not even some of the very public complaints from LEAF owners in Phoenix have really entered public consciousness. I doubt anyone will take note of these discrepancies and make a big deal out of it. I would have to agree that it's difficult for Nissan to offer a higher warranty threshold. They are likely bound by the cars they sold into hot climates. I think the Phoenix owners might ask a question or two about that at the town hall meeting next week.But now Nissan is offering a separate shorter 5 year/60k mile capacity warranty (to 66.24% capacity). My question is if people will assume that's the average case degradation of battery capacity (certainly the anti-EV people will try to make that point). If they came out with a capacity warranty that was the same length as the defect warranty (8 years/100k miles) I would have no question it won't be bad/detrimental in a PR sense, but of course they can't practically do that.
Yes, Nissan stands to benefit from a change of public perception. But other manufacturers will too. Battery degradation is something that will concern every new EV owner. Having some assurances, and minimum range expectations to go by, will help to decide which battery pack size to get, and what use cases to consider. For example, a Model S owner, who has purchased the vehicle to take advantage of the super charging network for long-distance travel will benefit from the assurance that he or she can rely on this use case to work, when the battery has aged a bit and lost some capacity. Given the competitive nature of the industry, we can expect this type of coverage to proliferate. I think that it will be important until the technology has improved to a point, where range loss over time will become immaterial.As I mentioned, Nissan's case is special in that they had lots of bad press from the hot weather degradation issue, so any sort of capacity guarantee is likely better than nothing. But for other companies who have not had any sort of battery degradation issue (Tesla is an example, the Roadster has been out longer than the Leaf and there haven't been any sort of degradation issue), I question if announcing a separate shorter capacity warranty will do any good. It may be better to let people assume that the typical 8 year/100k mile warranty already covers it.
