Well ya, I got years left still.
But at 8 years it's resale value will be much higher than at 8 years with a 15-20k battery replacement if it dies.
There's a cost/risk to consider there, it just working isn't a financially sound decision on its own
Edit: also by the time 8 years is up,getting a 1 year old car to eat that initial depreciation will be easier.
You essentially need a fully remade battery.
Most of the attempts to fix a single module don't work out and fail again as the battery isn't properly balanced.
It's almost impossible to do it without the scale of batteries the OEMs have at their service centers.
Maybe it'll get better as time goes on though
