Yes the 2013 had a couple of issues with heat problems. See my notes in my signature. (some may not be able to see my sig so I am posting here).Two months ago I purchased a Certified 2013 Volt. Sadly, it hasn't been a great experience. 3 visits for repairs in the first month of owning it and now an on-going issue with the heater the dealership hasn't been able to resolve.
My heater will sometimes work, sometimes not. Sadly when I've taken it in for this issue, the heater starts working again and they say they can't fix an issue they can't replicate.
This morning, it's 38 degrees out and the heater never kicked on, even after adjusting the temp all the way up to HI and keeping it on auto. It blew cold air for the entire 45 minute drive into work. I'm going to schedule another appointment, but I worry it'll be working again and I'll get the same answer that there is nothing they can do if they can't replicate it.
Has anyone experienced this before and been able to get this fixed? I've seen an old thread about needing a software update but the dealership insists the software in my volt is fully up to date so that wouldn't be the issue.
I really really want to like this car but it's not been a great experience so far.
2013 No Cabin Heat? Perform a forum search on: PIC5796 PIC5943 PIC5855 These PIC are known problems with the K10 unit being defective based on date, reprogram or replace the coolant heater control module (CHCM), and finally a stuck valve may need replaced.
The 2013 was plagued with these problems with heat. And there are countless threads on it. Should be covered under a warranty. Even if you cant find info use the three PIC numbers above and take it to you dealership.
