2016 Volt - no start, "Service Charging System" TSB # 16-NA-193 battery connection
After a few initial hiccups due to poor factory final quality control, I have enjoyed my 2016 Volt LT, and put 20,000 miles on it in 9 months on my long commute. About 60% EV, 40% engine. No operating trouble at all, so I was confident in taking it on its first road trip, Baltimore to western KY and back again. I had not really used the Mountain Mode before and it climbed beautifully, no problems going out, but the return trip...At a rest stop in WV, I parked and turned it off, did my rest stop business, returned in barely 10 minutes, and then attempted to restart. Got "Service Charging System", battery indicator, no start. Then an electronic seizure where she just drained her last power, lights flickering and dimming, gibberish on the DIC. Got OnStar to get a a tow truck to me before all power was lost, total brick by now, but fortunately OnStar was able to follow up with a cell phone call. I am so glad those doors open from the inside when all power is lost, although you have to pull the handle twice.
The wrecker comes, I need to get it from park to neutral to get it aligned up to the flatbed, but can't do that unless you have some battery. So, we jump started it using his 12v power pack, connected at the engine terminals just like the manual says. Miraculous healing! DIC is back, engine starts, all is well. Towed it to a dealer in Charleston anyway, closed at 0 Dark Thirty by now. Got it off the flatbed and I start, stop, start it again several times with no problems, drives without trouble. I took the chance to drive it back to Baltimore, and made it.
So, reading and searching relevant posts here, it might be a bad 12v battery, or something in the 12v battery charging system. But has started/stopped again several times with no issues. Off to the dealer tomorrow. There are no error indicators on the DIC. Hopefully they won't tell me nothing is wrong. I feel a bit jilted. I got the Volt, rather than an EV, so I could drive out of state without worrying about battery range. Can I trust it now for long trips? Should I have bought that Prius V I was looking at?
And that tire "repair" kit... I swiped a curb on the same trip the day before (ok, not the car's fault) and lost one of my OEM Michelins immediately. Repair kit useless for a sidewall wound. Of course, everything is closed at night. Spent the night in rural KY and waited for Walmart to open Sunday morning...incredibly, they had the right size and put on a new Goodyear with the TPMS working and everything. I will likely get a spare. That's not the Volt's fault - the whole stupid car industry is trying to get rid of spares. We need a campaign to get the feds to enforce a must-have-spare tire requirement.
Maybe it was the Supermoon..
