It certainly doesn't hurt it.
It actually influences me to purchase ANY Nissan. They handled the issue pretty horribly. They should have done this immediately instead of jerking around the consumers.
Strange too, how the warranty basically says that if it falls below this certain threshold, Nissan will simply improve it slightly until it is above that threshold (essentially 75% capacity). Sounds like they'll just band-aid it until the vehicle is out of warranty.
I could see that costing MORE money for Nissan as opposed to just fixing it correctly (to ~100% or so) the first time. Consumers could be taking multiple trips back to the dealership for warranty fixes that
cost Nissan money, not to mention piss off the consumer.
I'm sure they have a math scale figured out already based on battery degradation vs time left on warranty. (Say if there are 5 days left on warranty, fix it to 76%, if there is a year left, go with 81%, etc).
