I've been following this thread and its very discouraging. We have a 2012 leaf, purchased new and have babied the battery in a climate that rarely drops below 60 degrees F and rarely exceeds 80 degrees F. We saw our battery drop to 8 bars a month after warranty expired (when battery replacement was $6,000), and now with 54,000 miles on the vehicle, we are down to 7 bars (we were just quoted $9,000 for a battery replacement). Two words - STUNNED and PARALYZED. Stunned because it is hard to comprehend how NISSAN is allowing their core EV community to feel like they have been so completely duped. Paralyzed because while the car is in good shape, range is so limited that even local driving is starting to be difficult and the car is worth so little ($3500 on the market, less than $2000 dealer trade in) that its not worth selling. Outside of free parking at our local airport (12 miles round trip), its hard to remain positive about this early adventure into supporting the EV transition. This absolutely extends into any thoughts of a new EV purchase from NISSAN. For me this experience has made me an angry cynic about NISSAN EVs and about the company, and skeptical about EVs generally. Now when people stop me to ask about the LEAF, I simply say it was an expensive mistake - even if it has felt good to charge our Leaf using the PV on our roof. Cost of the car plus a new battery at 8 years (assuming we go another year on this battery) greatly exceeds purchase prices and normal maintenance costs for comparable ICE vehicles - and that includes the generous fed and state rebates. And the dream of upscaling to a cheaper and more powerful battery was apparently a complete delusion. And far from a win-win environmental solution, spending half the money on a fuel efficient PRIUS and sending our PV electricity to the grid probably would have been an environmentally and economically more sound strategy.
So....Was the idea of upgrading on the LEAF battery (more capacity and cheaper in 2020 than 2012 when we purchased) something I made up to feel good about spending so much on a vehicle? Is it fair to say that NISSAN EVs are not ready for prime time, with even newer models still having battery longevity issues, and that NISSAN should cede the market to real EV companies? Or do I have a lemon of a battery and I'm just unlucky. Are battery issues something that cut across the EV industry (threads highlight out of warranty battery issues for Tesla can be harsher financially), or has the next generation of EVs from other companies resolved these issues? Maybe most important, do any of EV manufacturers design / allow for future battery upgrades at a lower cost?
