... Unfortunately, I'm out of warranty based on time and mileage so I had to pay full freight on this one
It was about $2400 when it was all said and done. Even with this expense, though, my Leaf is still 2.5x less expensive to operate and maintain than my gasoline-powered vehicles.
Did you keep the old one?
Likely it could be repaired by someone with inexpensive diode
Dealer will not do that.
They will only replace the whole charger which is very expensive.
On Prius shops sprung up that could do diode
I haven't heard of anyone for LEAF charger yet, but it is probably just a matter of time.
You asked how common charger failres have been.
They were fairly common early on.
Haven't heard of too many recently.
Some died from GE EVSE use.
Nissan programming had an incompatibility that was corrected by P3227.
Mine has lasted five years and four months without failure.
But I only have 35,000 miles.
So about half the use of yours at failure.
