IMO (and what'd I'd look to do in your situation) - instead of doing that I'd put the money towards switching to a leased car as soon as possible. A 2-year lease is probably best for AZ owners - at this point we still don't know how fast the battery will continue to degrade in the heat - so I'd suggest a 2-year lease unless you very rarely need to drive more than 50 miles / charge.dsh said:We may as well as start saving towards a new $13,000.00 battery pack.
Let's say that you need a new pack every 3 years because of rapid capacity loss and at that point you need a new battery to keep the car usable for you. Also say that you can lease for $300/mo out the door (you can do significantly better than that with a 2-year lease these days).
The 3-year lease cost of $10,800 is less than the cost of a new battery pack - and you get a brand new car every 3-years, too.
You save money - you get a fresh battery/car every 3-years and the latest technology - and Nissan bears all the risk.
It's a win-win for the customer and IMO a no-brainer for anyone who lives in a hot climate.
The other alternative - lease a Volt - great lease deals on that car and it has a very well designed TMS for it's battery which appears to be holding up to AZ heat after 1+ year with no issues.
