I just had #17058 and #16055 software recalls performed on my '17 Volt. It was out of juice when I took it to the dealer. When I returned home it got a full charge on my wall charger (12amp). Drove fine to work where we have L2 ChargePoint chargers. Shortly after plugging in there, I got the "Your Volt is no longer drawing significant power.." text. Odd, I think. So I head down, unplug/re-plug and watched the ChargePoint to see if it threw any errors. I could see the normal startup sequence, KW start to climb to ~3Kw - then it threw a "Waiting for Vehicle" message. My car was happily blinking green. I tried different ChargePoints (we have several) - same result although not all threw the error message. I tried just ignoring the message to see if it was just a red herring, but when I got in to drive home - 0 miles.

Plugged in at home, and can see the miles climbing up so seems to be an L2-only issue. This is the first problem of any kind I've had on the Volt (other than wimpy climate package..). I just pulled the 12v battery to force a reset, and plugged back into my L1 charger for tomorrow.

I'll update post after I try again at work tomorrow. Very disappointed in the whole experience. Will not be considering Bolt..GM needs to figure out a battery is only part of their challenge.

I had the same software updates done without issue. Great work, GM.

From GM Manual/Recall




Vehicle Will Not Charge With High Voltage Charger, Vehicle Will Not Charge 12V Battery, Battery Lamp On DTC P1F5A P1F59 P0D26 P0D09 P1EBD
2016-2017 Chevrolet Volt
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI. Condition/Concern
Some customers may state that they have one or more of the following concerns:
1. Vehicle not charging 12 volt battery.
2. Unable to charge the HV battery.
3. Dead 12V Battery.
4. Battery Lamp always on in IPC.
5. One or more of the following dtc's: P1F5A P1F59 P0D26 P0D09 P1EBD.
Recommendation/Instructions
This concern may be caused by a open 15 Amp fuse in the High Voltage Battery Disconnect Relay Assembly on the front part of the High Voltage Battery. If you experience one or more of the conditions above, check for an open 15A fuse ( #2 in photo below ) in the Battery Disconnect Relay Assembly.
Disable the High Voltage system per Service Information and use Document ID: 4177883 to reference the 15A OBCM fuse. Check for a open fuse. If the fuse is open, replace the fuse and then retest the vehicle for normal operation. If the fuse is not open, follow normal diagnosis in Service information.
Note
To obtain a replacement fuse, please reference the current version of PI: PIC6182.
Caution
You must retain the old fuse that is open, GM CCA is going to request that fuse back for analysis. Warranty Information
For vehicles repaired under warranty use:
5031780
High Voltage Battery Disconnect Relay Fuse Use Published Labor Operation Replacement Time
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

The forced reboot (disconnect of 12v) seems to have worked, took a partial L2 charge the morning (had to drive) and is plugged in again charging correctly. Spoke to the dealer, said he'd seen similar a couple of time.

@tharvey57 I think that means ALL charging failing - in my case, it looks like the L2 negotiation only was failing.

[EDIT] another post before this still in moderation - this BB is weird..tl;dr - I hard-booted the car by disconnecting the 12v and at first seemed to work, but..spoke too soon. It L2 charged fine for 6KW, then stopped and after plugging back in, exhibiting the same symptoms as before "Waiting for Vehicle" after looking initially like it was going to work.

I really hope this isn't your problem, but it almost sounds like a cell fault issue. Somebody else on the forums had intermittent problems using L2 charging and eventually one of their cells failed. I also had a cell failure but I hardly ever use L2 charging so I never noticed an issue until the car wouldn't go into READY mode one day while I was on vacation.

It stabilized for a couple of months after again re-setting the 12v battery, but started to re-appear (in slightly different form) a few weeks ago. It 'feels' more like a computer/software error, plus it corresponded timewise exactly with the update to correct the recall.

Now, the symptom is it constantly reverts to 8amp charging (all other parameters like delayed charging are fine). And the L2 charge failure is now more immediately. However, using the My Chevy app - I can force the L2 charge to start - which is why I think it's SW. Going into the dealer Friday so hopefully they have good diagnostics for the pack/cpu etc.
