My 2013 Volt, base model, was until today, the best car I've ever owned. Found out the EBCM was throwing the C012E and C12FE codes. There was never an ABS, SES or any other visible indication of a problem.
That said, this is how we ended up here.
All three motor mounts were replaced because we felt a thud when we moved from Park to Reverse or Drive, when touching the brake, or when taking your foot off the throttle in any mode. The mounts were all three indeed worn out. Very worn out.

However, that revealed a remaining issue. Just touching the brakes in any mode, the car would buck or it felt as if the ABS was trying to kick in. All the other thuds are gone.

The car showed the above mentioned codes. Tech says the EBCM is bad. Guess what? The part number 19435410 is discontinued as of May this year and not a single dealer in the US or Canada has one. I even called GM directly to confirm. They would not provide the manufacturer name.

So, GM has essentially turned my favorite car into a brick. I'm stuck with a great car that I can no longer drive. It has 130k miles, still gets nearly 40 miles of electric range when it's not hot outside (Florida) and is now undriveable.

I understand the 10 year rule for parts, but there's usually some stock available, and an avenue for aftermarket, but not in this case.

Thanks, GM.
I've been a brand loyal GM customer for over 40 years and probably 40 plus vehicles, and I feel completely betrayed.

Beware Volt buyers, and I suppose GM buyers in general. It appears there are many parts that are particular to the Volt that either have, or will be discontinued and you will be left with no where to run and no one to turn to. There are no after market avenues.

I am researching the possibly of having the module repaired, but I'm not holding out much hope for that.

Used is not an option, because once the EBCM is flashed with a VIN, it cannot be nulled and refreshed. Thanks again GM.

Any suggestions on a rebuild or a new part hiding on a shelf would be amazing.

It really is a bummer. It was one of, if not the best car I've ever owned, until it wasn't. Sad that GM just threw in the towel on this car and the people who owned them. I've been a loyal GM customer for over 45 years. I feel a bit betrayed, but that's the way things are now. I'll keep driving my 95 Buick Roadmaster and my wife will keep driving her showroom condition 2001 Pontiac Montana. Both far cheaper and easier to maintain.

I've worked in the semiconductor and radio communications technology industries my entire life. I am a fan of tech when it's built well and designed to be reliable. And I really thought GM was going to do great things with the Volt. Alas, they couldn't figure out how to market it and then they bailed on their own product and bailed on those who decided to buy it.

It really is an outstanding vehicle but if the tech is unique and complicated it seems inevitable the repairs will be expensive. Then of course there is discontinuing the line which they may bring back.... That's another downside of Ev hybrid technology is it's a small niche.

I'm sorry your vehicle broke down so bad

I too, agree. GM had something at least 10 years ahead of its time and squandered it. They're pretty good at that.
This car really was the best car I've ever owned, until it wasn't, and I've owned probably 45 plus cars in my life, nearly all GM.
I was fully aware it was a limited run vehicle, but I was amazed, disappointed and now a bit bitter at how quickly GM pulled the plug.

The economics of it changed. Specifically, batteries got cheap enough that storing reserve range over and above daily driving in more battery made more overall financial sense than storing that same reserve range in liquid fuel, an engine, more complicated gearing and a fussy emissions system.

I am still not sure how good an EV is if you live in the northern tier of the US. In Montana I've heard Tesla drivers say the automatic door handle gets frozen shut at minus temps. I don't know how the batteries handle that level of cold or if it shortens lifespan?We can easily hit minus 20 a few times in winter or colder. So I like the engine turning on to heat up the cabin. Fossil fuels will have a place in the extreme north for many decades.

Hi ismaelvalencia,

These are all questions for the contact I gave. Hopefully it's solved by now, given my slow reply -- sorry!

I'm sure that the mechanic needs some adapter that goes from PC to car module/s. If your mechanic doesn't have one or isn't willing to do it, hopefully you'll find one that is willing. Also my contact only communicated with me through Facebook Messenger and didn't respond to phone text messages from my mechanic, but did call mechanic when I provided the number and communicated between them about the day/time ... hopefully my contact would be willing to make an international call. I hope this works out.

If it doesn't with my programmer contact, I hope you can find someone there!

Best of luck!
