Almost Dead Volt

i have a MY2016 Volt Premier

on Monday while driving towards the freeway the DIC and MyLink displays flickered between bright and dark then the DIC blanked out and when it returned it showed the background GFX (Classic Enhanced) but none of the info parts were updating(speed, Electric Charge, Fuel) and the Power Loss/Gain on the right side froze and gave at least 10 different "Service..." messages

tried restarting the car once at a light and it wouldn't do so but since everything else worked fine i decided to drive it to the Dealer and have them look at it

when i got out at the dealer it wouldn't turn off completely and the headlights stayed on

when the scheduler went out to look at it it had finally turned off and now wouldn't turn on

later that day after getting a loaner and going to work the informed me the had needed to reprogram the HVAC and that fixed it

on Tuesday all was fine
on Tuesday night we got almost a foot of snow(rare for us Portlanders to get any snow) and on Wednesday morning it wouldn't start again with almost the same symptoms

i cannot get it to start by using the start button
i have to use the Remote Start sequence on the fob
this time there is a little icon of a wrench(Service Electric Parking Brake Light) that cycles with what looks like a headlight and an arrow that points left and right

due to all the snow tow trucks are hard to find and im trying to see if there is some way i can get this at least temporarily fixed so i might drive it to the dealer myself

Heh, you might want to search for the threads for loose battery connector. I recall reading quite a few people having an issue with a terminal block involving the 12V battery. I forget if it's located in the engine compartment or near the 12V battery itself in the rear of the Volt. This connector being loose led to many weird issues. Amusing that GM is suggesting looking for it. Maybe they should issue an advisory or something to check for this first when strange symptoms arise.
Chivolt, thank you for the solid link. I'm too lazy at times.

Entry45, it's judgement call. I too hate it when a customer chimes in with suggestions. I then counter with a series of more in-depth questions for troubleshooting. If they proceed to answer honestly (including "I don't know", nothing wrong with that, it switches me to a different lines of questioning) and concisely, I find that input to be valuable in root-causing an issue. Everyone wins since you get your car back sooner and it's record turnaround time for the tech.

Since they mentioned that GM instructed to look for a loose connector, it's perfectly reasonable as a consumer to research "chevy volt loose connectors" and find links mentioning the underhood terminal block. You were just doing your due diligence. Sure beats the customer that complains, "it drives funny" when they left the parking brake on.
Dang it. Sucks to be the guinea pig we learn from for new bugs. Hopefully, it's actually not a new bug and just another old one with different symptoms. Scary that your Volt person has to go into training. Maybe he/she will make some new connections to reach out to after returning from training.
