I did have a power pack, and I did jump start the car, but it still was undriveable and had to be towed to the dealer.

Thanks, SparkE. One difference between my experience and the one described in that thread is that his car was left unplugged for a month in cold weather, and mine was left for less than 24 hours in a garage. He didn't give much detail about it, but it seems that jump starting, which one would expect...

Or does it stay on until what? If it times out, how long does it take?

It would help if you cited authority for your answer.

Thanks.

DanDietrich, I checked the 12V battery voltage with the car parked in my garage and turned off. It was 12.45 V. I then checked it at intervals. Two hours later it was 12.66 V. Clearly, either the 12V battery was getting charged or had been charged in the interval because that's the only way the volt...

I jumped my car twice. The first time, when it was completely dead, it woke it up and allowed me to charge it. I tried it again a second time after discovering that it was still undriveable after charging. I verified for myself after getting it back from the dealer that the 12V battery gets charged ...

Further update: The service manager did finally call me after about five hours. He tried to reassure me that the car wouldn't shut down while in motion. However, he was much less dogmatic and much more willing to say so when he didn't know something instead of making assumtions. He promised to conta...

I picked the car up today. Before I moved it I checked the 12V battery voltage; it was 12.5. I told the man at the service desk that I was concerned about a safety issue, i.e., that, if the 12V battery went dead when I was driving, would it be dangerous? Would I lose brake function? Would the brakes...

Update: They called back today and said they found nothing wrong with the car. I had a long, unproductive phone conversation with the service manager (When they called, the tech who worked on it was no longer available.). He said that they had checked the battery again twice today, and it was stayin...

We’ve had our 2019 Premiere for about two weeks, so, this is just a newbie observation. Should not the EV manufactures out there put a low 12v battery warning light/symbol in their vehicles? Rich Of course they should. Follow-up: The car was plugged in for about 60 hours, about 45 hours of which wa...

Last night I parked my 18 month old 2017 Bolt EV with about 5400 miles in my garage. It showed 150 miles remaining range, and I didn't plug it in. This afternoon, I found that it wouldn't respond to the fob, wouldn't respond to door button presses, and when I plugged it in, the charge light didn't c...
