No heat in 2013 on EV

So I took my 13 to the dealer for the axle click noise and no heat most of the time I'm on electric.

They said my caliper slides need to be lubricated to fix the axle click noise. They want $70 an axle and want to do both axles. And they want to reprogram the HVAC module for $218 plus a $109 diagnosis fee. I told them I'll pass on everything.

After the car sits at night I have heat. If I stop somewhere and shut the car off then back on again within a few hours I won't have heat the 2nd time. If the car sits 5-6 hours the second time, I'll have heat.

They are reprogramming the charger module under voltec warranty as there was a code for it.

The SW actually told me the engine NEEDS to run to produce heat as the car needs to be in open loop to make heat. So basically he doesn't have a clue. And this is the dealership with the volt specialist in the area.

kWh jumps up as if the heater is drawing power but no heat.

This axle nut torque issue is nonsense. I have had this and I told the dealer exactly what to do, they said they had heard nothing about this.

It is madness because it is a very common fault on GM/Vauxhall cars, a well known issue on the Astra model, here. Same hub ends AFAIK, out of the GM bin.

It's insane that this company doesn't talk about high rate faults that customers experience with their cars.

Vauxhall/Opel are being sold to PSA (announced yesterday) so maybe PSA will actually be a better owner of the marque than GM have been.

As for the heater, it seems there can be one or multiple of a relatively small number of faults here;-
a) the electric coolant pump is not working properly. This IS covered under the Voltec drive warranty.
b) if power is drawn when heater shows 'on', then the blending valve between the HVAC circuit and the engine circuit is sticking open, either completely or jamming open a little.

It would seem in the OPs case that once the system cools down the valve does return to the fully closed condition but seems to remain open for a while after the system has warmed up.
