I keep hearing horror stories over and over again of people being stranded due to BECM failure.
Is this failure inevitable to happen on all 2017 model or is it isolated among a few modules. Has GM traced these potential failures to specific VINs or is this a crap shoot?

The BECM in my 2017 failed last summer. But it didn't strand me. The electric range read zero and the ICE turned on every time I started the car. Also, my air conditioning didn't work. My dealer told me I could drive it until the part came in but I didn't because the weather was warm and I was concerned the battery might overheat without the a/c being available.
I don't know if they had a bad batch of BECMs or if they are all subject to premature failure.

I don't think they had a bad batch, I think the BECM was a marginal piece of (insert your own word here) which means some will fail and some won't depending on the luck of the draw. Hopefully the replacements are of better quality. Your A/C doesn't cool the battery, that would be the Mitsubishi Outlander that does that. The Volt is heated and cooled by coolant just like the ICE motor and the electronics (three systems).

The A/C compressor does indeed provide chilled coolant to cool the battery. From WOT's post way back in time:

Yep. That's the reason why you'll sometimes be driving around in warm weather and the air vents start blowing cold air - the battery got warm and the computer turned on the a/c.

....and it costs $4000 with a 12 months waiting list?

You must be referring to a new A/C. Where did you get the price and wait time? I saw another thread where a member replaced his own after the dealer quoted like $2500.

I was being facetious
