Last week we got the orange car with exclamation point/mark warning light on our 2017 Chevy Bolt. When I checked the MyChevy App, it informed me that we had an issue with the Lithium Ion Battery and that it needed to be taken in for service. Our local Chevy dealer service department (which replaced the EV battery last year under the battery fire recall) told us that the problem was the "Off Board Charging Module" [Off-Board Charger Control Module] which they would replace once the parts came in (in a couple weeks). But that's all the detail they had for us. Has anybody else had this issue? Did you get any more details on this failure? They said we could continue to drive the car while we waited for the replacement and that we wouldn't be charged for the repair.

It sounds like the same part that failed on my 2022 bolt. If so, the car is drivable but won’t charge. I’m still waiting for the part after 45 days.

Clarify please. It obviously won't charge on public DCFC, but will it charge on AC?

There is an on-board inverter (aka charger) that converts AC from your home electrical system to DC to store in the batteries. There is also a separate component called the off-board charging module that communicates with DCFC equipment for faster charging. If the off-board charging module is defective, it wouldn't seem to impact AC charging.

I contacted the dealership and they clarified that I can charge the car on my level 2 charger but that I should not use DC rapid charging. I also noticed that after I brought the car in to the dealership, I got a notice on the MyChevy app that they had charged up the vehicle. So that suggests also that it's okay to charge so long as you're not using the DC rapid charging.

Good to hear. So you are good to go until the part shows up.

I'll be watching this one. Have a 2017, though I seldom DC-charge it. Should be covered under the remaining 8/100K warranty for the "hybrid system" parts.

Does raise a question for the systems people, though. Is this module in the battery, and therefore part of the recall process? And if it's a separate module, is there a way to adapt it to 2-way charging of a house?
