I get the "Unable to Charge" message on my dash regardless of the charger being used. My L1 and L2 chargers at home have the same issue and also any public ChargePoint charger, so I cannot charge at all!

The home chargers give a "Charging Fault" immediately when connecting the cable to the charge port of my Bolt EV. The ChargePoint charger displayed an error: "Error Code #102 - Ventilation Fault".

I brought the car to my Chevy dealer and they reproduced the issue and after running diagnostics have ordered parts for warranty repair and provided me with a loaner car.

They were not very detailed on what he problem is but said that they think the issue is with the Charging Unit Control Module. No ETA on repair at this point. :crying:

"Unable to Charge" "Charging Fault" "Ventilation Fault".

Charging Unit Control Module

Sounds more like a problem with the power electronics cooling loop to me. Did anybody check the coolant level in the reservoir at the front, driver's side?

so you are reporting that your car had a problem, you took it the dealer, they diagnosed it, and they are going to fix it under warranty?

I'm sorry I really don't see the issue here, car's break, you get them fixed.

 

[PhilBo]

In case someone else encounters the same error code we now know it's not a problem the owner can fix. Thanks for letting us know what course of action needs to be taken.

 

[GJETSON]

Yes. And please keep filling us in. I would love to know what they ultimately do.

 

[One1whaoo.]

Oh, didn't you know? That 238-mile range you bought the car for?
That's 238 miles, total. Ever. That's all the car will go. Period. Recharging is a myth.
Time for a new Chevy!

I just got an update from Chevy. They have now determined that the issue is the "Power Line Communication Module" which they say is NOT covered under warranty.

The service rep could not answer basic questions so I asked to speak with a supervisor and I am waiting for a call back.

Thats a very ODD response and seems incorrect. One of the concerns I had with the purchase was the high amount of electronics and Large battery pack. I was under an impression that all of that is covered for 8 years 100,000 miles (as part of the factory extended HVDC battery warranty).

 

[klowenst]

I reviewed the warranty section of the manual and it lists many electric components by name (Battery Control Module, DC Power Control Module, High Voltage Battery Disconnect Module, Battery Charger Control Module, etc.) but not the "Power Line Communication Module" specifically.

Thanks for the tip. I asked them to please check the coolant level in the reservoir at the front, driver's side. I told them about the ventilation fault and provided a picture of the error, but I'm not sure if they checked the coolant.

 

[Sibilance]

I know this sucks, klowenst, but thank you very much for reporting on your experience so far. A lot of us do not think of this as whining, but as keeping the community informed about potential issues.

I'm interested in how this turns out for you. Please keep us in the loop, greatly appreciated. It would be nice to have a better understanding on what is and isn't covered under warranty. I have an extended warranty on my Bolt, but most here have skewered me over the coals on how unnecessary and wasteful I am. I know, I hear it all the time. What year is your Bolt, how many miles?

OK. Now you've got my attention. Thanx for reporting in, and if you can really nail them down on an electronic part that is not under warranty that would be helpful.

Please tell us the year and mileage.

And BE SURE TO ASK FOR THE OLD PART!

You said your L1 and L2 stations at home won't work. Have you tried the factory charger?

I would be suspicious that the fault is what they say it is, if the above description of the part is accurate. If that's what's broken it would seem AC charging would work. That would tell me the dealer may be guessing, or an error code "fell through" to that an incorrect fault. Or sumpin.....

 

[GJETSON]

I don't understand how a part which is essential to the operation of your electric car can be "not covered by warranty."

The fact that your garage AC EVSE's didn't work shows the probelm goes beyond DC fast charging. Something stinks here.

As Coastal_Cruiser mentioned, it is mentioned in a GM press relaease.

However, I just searched a GM parts site for "Power Line Communication Module". There doesn't appear to be anything with that description.

I agree that it's strange that they would say it is not covered by the warranty. I could be wrong, but I thought that most things that were not covered by warranty are things that usually fail by "normal wear and tear" like brakes, wipers, etc. This sounds like something internal that is essential for the car to operate. I would escalate to corporate GM to try to get an answer before paying anything.

 

[Nook]

If your vehicle is still under the warranty, I would expect any "critical electronics" to be covered. Not being able to charge puts it in the critical basket, in my view.
I agree with others that the explanation doesn't seem to match the symptoms. Ask for the "bad" part back. Even ask to be shown/demonstrated for you how that part is bad. Putting a different part in and the problem goes away does NOT prove that part is bad. (Could be re-seating, rebooting, bad connection, etc. that was coincidentally cured with the part swap.) Putting the bad part back in and the problem reappears does prove it's bad. If they can't do that, I would be very hesistant to pay for the part and its associated labor. (I would pay them an extra half hour of time to show me putting the suspect part in makes the problem come back.)

If you don't feel like you get satisfaction from the dealer, I would encourage you to write to corporate. I had the transmission go out on my 2001 Ram at 3years 1 month, but only 20k miles. I got $4000 off a $4400 job with one letter.

 

[GJETSON]

I would be very hesitant to pay for the part and its associated labor.

Do not give them a dime. You absolutely don't need to pay for any of this. Once they have your money, you will have to fight to get it back. I would speak to GM corporate before allowing these shysters to do anything.

 

[klowenst]

The car is a 2017 with just under 45K miles on it.

The dealer is insisting that the part is not covered under warranty and they quoted me $380 for the repair.

I can't find this part listed anywhere as specifically covered under warranty but I also had the impression that any parts required to charge the car would be covered.

The dealer told me they reported the incident to corporate but I guess I need to figure out how to contact them myself at this point.

I'm not sure what you mean by Factory Charger. The L1 is the portable charger that came with the car. Chevy has the same issue with their L2 charger.
