No $50 check for me. Of course, I bought mine second hand off-lease.
I did get the notification about CarWings, so it's not like they don't know where I am.
Kathy, I plotted my battery health %-age from monthly LEAF Spy reports and like you, I expect the battery to outlast the warranty. I suppose that's a good thing, but at 80%, my range is sometimes a bit shy of what I'd like. I'm kind of on the fence about getting the maximum mileage out of my current LEAF (just flipped the odometer over 30K) or upgrading to something with a bit more range.
I'll be keeping my eye out for some later model off-lease LEAFs and/or I'm considering holding out for a Tesla Model 3 (announcement tomorrow for those who aren't up on that sort of thing). It's hard to beat the existing supercharger infrastructure (www.supercharge.info
