Hi all, I am a new Volt owner - bought a brand new 2019 Volt in November. The car has 1720 miles on it, and I had taken it on its first long road trip (Las Vegas to Indio, CA and back) at the beginning of the month with no issues. I had been loving it up until the other night.

I was driving home at around 45mph on Sunday night when the car suddenly stalled. I was on the last 6 EV miles and had a full tank of gas, driving on EV L mode. Luckily I was on a quiet street at night and was able to pull over to the side.

The car gave me the shift to park message. Then I got the messages "initializing wait to shift", "propulsion power reduced to 0". The car would not work, wouldn't shift out of park. Changing to hold mode to use the gas didn't make it work either.

I turned the car off and on several times, same messages - completely stalled. When I turned the car off I also got the message "Unable to charge" instead of the usual "plug in to charge".

I called On Star and eventually got towed to the dealer in the middle of the night. They were closed the following day and today because of Christmas, but I will talk to them tomorrow.

Before this happened to me I hadn't read about this problem, but since having it occur I realize it is far too common on older models. It's unacceptable to me that this would still be an issue on 2019 Volts if it was a known fault in the past. As other people have said this is extremely unsafe - I could have been stalled suddenly on the left lane of a freeway.

Btw, the orange engine light also came on and I got an automatic On Star Diagnostics message to my email: "An issue with the lithium-ion battery in your 2019 Chevrolet Volt has been detected. Please service your vehicle within 1 day."

You can file a complaint with NHTSA . THAT IS THE WAY RECALLS ACTUALLY DEVELOP. If no one reports nothing happens.
https://www-odi.nhtsa.dot.gov/VehicleComplaint/

People who had this problem in the past and had it fixed can file a complaint as well
If a recall is eventually issued and you have filed you can make GM refund costs of the repair etc.

Seeing as how this is a brand new Volt, it's all covered under warranty. Personally, I would wait until the dealer figures out what's wrong before doing anything else. I'm guessing, based on what's happening, that this is probably more of a software issue. The problem with all of our vehicles today is software runs more than people think they do.

Keep us updated on what the dealer has to do to fix it.

In the future know that if you press the blue OnStar button on the overhead console you can speak with an OnStar representative. Specifically ask the representative for any diagnostic codes; If there are no codes you can ask the OnStar specialist to run on=demand diagnostics on the vehicle. Get the ticket number from OnStar so you can provide this ticket and any error codes to the Service Department.

Please provide an update when the service department determines the cause of the problem with your 2019 Volt.

Don't you have to pay for on star service though?
Get an OBD II Bluetooth adapter off eBay for $15 and the free app called Torque. Will pull all codes. No monthly fee to GM

I do plan to file a report with the NHTSA once I have whatever paperwork comes back from the service department. At the least that will help in case a pattern emerges with the new Volts. And looking through their website for past Volt models, it seems to be the most common complaint. But yes, it will be under warranty.

As far as On Star goes I did hit the overhead button to call them, but I didn't know at the time to ask them for diagnostic codes. The dealer can still pull them though, right?

I thought On Star might walk me through some steps to try to restart the car but they just first thing ordered me a tow and took my details. I wasn't actually planning on subscribing to On Star - I'm just on the free three-month trial that you get when you buy the car, but it was good to have in the moment.

Btw, my orange check engine light was also on and I got an auto diagnostic notification email from On Star when it happened: "An issue with the lithium-ion battery in your 2019 Chevrolet Volt has been detected. Please service your vehicle within 1 day."

The 2019 Volt includes 60 months / 60k miles roadside assistance. More here: https://www.autobytel.com/chevrolet/volt/2019/warranty/

Vehicle diagnostics are included for 10 years under the new Connected Access Plan:

"One key change is to the most basic tier of connectivity services offered free when buying new GM vehicles and included in all OnStar plans. The Connected Access package retains vehicle diagnostics, dealer maintenance notifications, driver report cards and the Marketplace app for newer vehicles, and will be extended to 10 years after purchase, from five, providing GM a richer trove of data on a vehicle's condition and performance over time."

when having a stutdown problem one item people miss is:

1. close doors and MOVE all FOB's away from the car out of radio range.

this is part of the complete shutdown process.

wait a few mins then return and try to start again


start car and then open hood and see if the ICE starts. ( then if the 12 volt battery is low it MAY get a charge)

AND have tow person check the 12 volt battery voltage

Can I use the tinfoil from the hat I normally wear to shield the remotes?

Yes you can. A tin foil hat is a Faraday cage.

Got car back today. Here's the report from the dealer:

"hybrid battery cell #70 is bad intersection 2 causing code p1bb5 pulled code p1bb5. checked for bulletins. cleared code and retested. code returned. 1.3 olh pulled hybrid battery and cover. working with si doc 4200140 tested section 2 battery harness with meter. all circuits less than 1 ohm. installed breakout box and tested all batteries in section 2 all measure 3.6 vols except battery #70 measured 1.77 volts. called tac and was advised to replace section 2. replaced section 2 and performed balance charge. installed cover and smoke tested ok. reinstalled battery, filled cooling system and road tested ok."

Hopefully it was just a faulty part and there are no further problems.

Glad to hear you back on the road. Hopefully that's the last issue you have...

It's hard to believe that one cell caused such a big problem. Well, here's hoping that's your one and only glitch, and it'll be smooth sailing for many years!
