I find my 2014 (25k miles) now has no heat in EV mode as so many before me. Working through as many posts as I can to find some assurances and I'm afraid I'm not finding much. I have an appointment for this coming Tuesday to get it looked at so I'm using this time to get armed with knowledge before the dreaded hour.
The first real question is whether this is covered under warranty or not? This thread seems to say no or maybe: http://gm-volt.com/forum/showthread.php?271489-coolant-pump&highlight=heat Unsure if Customer Service resolved this one way or another.
And post #48 here: http://gm-volt.com/forum/showthread.php?209170-2014-Volt-Heater-Problem/page5&highlight=heat also has me guessing. My 2014 was purchased new in May of 2015. So, am I out of the B2B or am I good? There just seems no end to the possible answers.
Don't know which post I ran across a reference to PIC5943. https://static.nhtsa.gov/odi/tsbs/2013/SB-10063994-2273.pdf Seems to be the culprit but we also have 2015's with the same issue so is this an ongoing thing?
So, the never ending questions still leave me here... Is the K-10 Coolant Heater Control Module replacement the solution or something else? Has there been a resolution with the software update only? Is this covered under warranty or not? Is there an actual one size fits all solution or am I at the mercy of the service department?
