Sorry. Didn't mean to spam. I thought I only posted in the two big BECM threads that seemed to be active.not an attorney but we can rely on you to spam this message to every BECM thread?I'm deleting all the duplicates.
That definitely sounds like a safety issue! I don't understand why our dealer then told us it's totally safe to keep driving ours?! My wife commutes with it daily on the highway. It intermittently gives the reduced propulsion warning (seems to be on really cold mornings), but that will go away after a few minutes of driving and a restart.I mean that's all pretty reasonable, in terms of compensations. Not asking to get anything other than what I paid for.
For the sake of discussion, though, the BECM failure events we experienced were serious safety issues. Total shutdown of car while in motion, one event almost leaving the car stuck on train tracks. It's not as if the car switched into ICE/reduced propulsion mode - it just unexpectedly came to a stop and was thereafter immobilized. My wife was driving, and good grief - if that happened on a crowded highway? I'm not sure you'd be able to get it onto a shoulder. IIRC there wasn't even power steering available in that condition. Not saying that falls into NHTSA's purview, but a serious safety issue in a general sense.
I can't speak to everyone's BECM failures, but both of our events were as described: car stops driving immediately, unexpectedly, and does not move after that. Side note: if this happens to you, you can hold down the start button for 7 or so seconds to reset things, after which the car may be able to limp home in ICE/reduced propulsion mode. I cannot remember if you also needed to have your foot off the brake to do this reset. Pulling the 12V probably has the same effect, but resets your CEL codes which impedes dealer diagnosis.That definitely sounds like a safety issue!

I would prefer to park it until it's repaired, but the dealer won't give us a loaner (despite the warranty including that), and we can't afford to rent another car for weeks on end.
Mine was replaced because it wasn't recognizing the brake pedal position sensor input.It's not clear to me how the BECM failure is a NHTSA issue of safety. Has anyone reported this to NHTSA as a safety problem and gotten a response that indicates they're taking it seriously? Air bags and seat belts and fire hazards seem to be their focus.
For anyone else looking for file a complaint, Report a Safety Problem | NHTSAI wish more people would report the BECM issue on the NTHSA complaint board - especially if it's causing a clear safety issue like suddenly stopping the car. I recently did a search on the board and found 9 hits for "BECM" or "battery energy" for 2017 Volts, and 0 for any other year (2016-19). But from this forum and Reddit it seems the problem is much more widespread. The government is not going to force a recall unless they have evidence that it's a serious and common safety issue.
Big agree. I think Voltec was probably the most brilliant drivetrain ever developed for a production car, but getting the sense that GM probably isn't interested in supporting the existing fleet.. well, that brilliant complexity is just a liability when not supported. Not to be dramatic, but I'm in the process of getting quotes to trade in/sell the Volt. I can't find myself with a niche vehicle with unavailable parts that I can't fix myself. Finally got mine back yesterday, so that was 77 days, and I'm super glad to have it back. The good news is there are apparently BECMs trickling out for the other folks here waiting.Whereas GM executives are done with the Volt/VOLTEC and have been since probably 2018.
I have always thought that the Voltec powertrain was the best of both worlds and absolutely the right way to go. No range anxiety while providing decent all-electric range. No worries at all about long recharge times during long trips. I thought it was a big mistake for GM to abandon it.Big agree.

It's lovely to have the car back. They're great cars. Just don't trust GM to keep mine rolling for the length of time I'd hope to own it.
Agree. I'm still waiting for someone else to truly take up the mantle of the Voltec approach, and keep wondering if GM will come back to it now that the consumer interest is catching up to what Voltec was offering 11 years ago. I do get that as a compromise, the Voltec drivetrain doesn't do the best in terms of efficiency once you're in ICE mode, so you end up with a car, on paper, that gets 42mpg.. an Accord or Camry hybrid look better on the window sticker. Of course, most of us Volt owners are actually getting hundreds of mpg in real life, but that doesn't make it to the window sticker. The way I've always felt is that it's the drivetrain Americans actually need, if they could only be convinced to want what they need.I have always thought that the Voltec powertrain was the best of both worlds and absolutely the right way to go.

Now that GM has dropped it and gone all-in on their EV-only push, other manufacturers are coming around to the idea that GM had with the Volt. EV batteries are heavy and expensive and they need to be quite large for a full EV. It seems more and more manufacturers are coming out with plug-in hybrid options that have smaller batteries (even smaller than what the Volt had) with gas engine range extenders.
It's sad to see that GM had it right all along, only to be mocked for not being a "full EV", and when they finally cave, it turns out they had a great powertrain that they abandoned.
lolI dread the time when I will have to send her to the Old Volt's Home.
