Hello. I have a 2016 Leaf S 40 (original 30kwh battery upgraded to 40kwh under warranty last August). The car has just over 100k miles on it - I bought it used with only 2k miles on it, and it has been working well for me generally speaking.

The S model does not have the heat pump heater. The resistance heater will not work if the car is above 80% or so SoC. While in the nonworking state, LeafSpy shows a B2772-00 09 HVAC PTC Heater Voltage HAC-75. When the heater is working, no codes are shown.

I know this is an expensive repair at the dealer, but it just seems odd, how it only fails at a high SoC. I'm not sure it is worth an expensive repair bill vs just not charging the car all the way up (I don't need that much range on my daily commute).
