At 58k miles my bolt started giving an error code, "service high voltage charging system". I took it to a chevy dealership and they said it was not their fault and that I had hit something that dented the bottom of the car and damaged the battery. They told me it will be $20k to replace the battery. I feel so cheated because I didn't even have an accident or anything and now my $28k car is totaled. Maybe I went over speed bumps too quickly? I am just going to let the dealership I bought it from come repo it. This has really turned me off of electric cars and I think it was a huge mistake to have ever bought this car.

Found another post of a guy saying something similar. He ran over a large rock and chevy told him his car was totaled too

WOW do I regret buying this car
Ran over Large Rock
Last week, I accidently ran over a large rock which dented the bottom of my 17 Bolt. It put an approximately 1-inch deep dent into the bottom of the car, just to the left of center but behind the plastic aero cover. It completely punctured the outer layer of sheet metal (~1/10-inch) and when I...

Maybe something with higher ground clearance, a curb friendly vehicle and something that does not need to be charged?
I can't believe the number of people saying they have bottomed out on curbs and speed bumps. My old 14 Volt was low so I was always careful... however, I have never even come close to bottoming out the Bolt. I'm just surprised that's all.
Can't pay me to have a truck like that. I hate lifted big tanks. Give me a small and lowered S10 with 450hp anyday.
Come on. Photo evidence. Please give the young man a chance.....
The dent on the battery housing seems to be on the front edge near an electrical connector... if you could get it to an independent EV expert shop they could PROBABLY disassemble the pack, pound out the dent, and replace that connector to fix the problem. Removal of the pack and replacing the connector may be expensive, but not $20K.

Checked 12v battery at autozone, battery is 95% charged.
Ran OBD2 diagnostic, got this:

You left out this part of his thread.
I will continue to say that you have no battery problem until you use one of the Bluetooth OBDII scanners to pull battery and other stats. If you used one of the AutoZone OBDII readers you are not going to get ANY reliable information. Those are great for an ICE car with a bad O2 sensor or misfiring engine. It will not help you much with an EV.
Sounds like the 12v Battery is eliminated from the possible problem.
Did you have them reset the CEL Code?

I don't understand the difference. The bluetooth one gives you more information??
I didn't have them reset the code but I will do that myself once I get my own OBD2 tool I guess.
In a chevy volt forum someone posted that they were getting the same error message, "service high voltage charging system" and then someone else posted "Checked your coolant levels I assume. If the sensor is flaky, you can clear the code with a code reader and it will let you charge, but it'll refire as soon as it hits full charge again. If the sensor is dead, it'll refire instantly."
So hopefully I will be able to charge after clearing the code. But how do I know which one corresponds to that message? Should I just clear them all?
Clearing the code will help the following.
1. If it immediately comes back as soon as it is reset then you have a problem.
2. If you are able to charge and it does not immediately comeback then something is wrong but not necessarily fatal.
You can open the hood and look at the coolant levels. One thing to keep in mind (at least in the Volt) is that the coolant is a sealed system and generally not user serviceable. If you have a coolant level issue, take it to another dealer. It will be under warranty and they should fix it.
Having the code reader will also let you see data on the battery and other components. Allow you to make dashboards to see those items in near real time. We can help further once we have those numbers. Sadly these are all things EV owners must go through when there are problems. This is a tech that really relies on the owner knowing more than the dealer in order to get something fixed and fixed under warranty.

Ok I'm on my way to get a bluetooth obd2 reader now.
Also the dealership really messed up the shield underneath my car so I hope if it comes out that it is actually a warranty issue that I can get a refund for my diagnosis, and they fix my shield for free.
The difference is in the software. The Bolt sends out bunches of codes that ordinary readers do not understand. Torque Pro with Telek's Bolt PIDs picks up and displays all those extra codes.
Trust that it's worth the money and effort to get addition information to help solve your problem.

Also this woman at autozone says their obd2 scanner does just as much as this one so that's weird. Maybe she doesn't know what she's talking about
There is Nothing at Autozone that will help you diagnose this problem. I repeat, NO LOCAL STORE will have what you need to resolve this. We have provided links to what you need. If there was something you could buy at WalMart or a Parts store we would tell you. Take that Scanner back as the only thing it "Might" be able to do is clear the CEL. It will give you 0 information on the battery or other charging components. EV's are OBDII compliant but they have a lot more information than is ever programmed in an off the shelf OBDII scanner.
The Bolt may be a ~4 year old platform but the tech in it is still Bleeding Edge as far as car repair shops and dealerships are concerned. Most of the people on this board have owned an EV of one sort or another for years and have tried different approaches to troubleshooting EV's. Please buy the OBDII Bluetooth scan tool that is posted. I am sure even the $30 one cost less than what you just bought that will not do what you need done.

At long last, here is my work in progress! Please only share the link and not the values directly. I would like to make this a collaborative effort to discover and learn more about the car. I have included some basic recommendations and directions on how to get started for both Apple and...
Find out the details on what is coming from the OBDII. You can see all sorts of information. If all battery cells have good readings and the pack resistance is normal then it is not the battery.
Also, clear the code and try to charge. There are lots of things you can be doing outside of the dealer. Sadly these are all things people need to learn to not be taken advantage of by dealers. Plenty of stories of things that should be covered under warranty that were charged and paid for by owners simply because they did not know any better.
But I for one hate waiting for mail order to arrive. Buddy wants his car back to continue making a living to pay the rent and put food in his belly.
@Jordan Shackelford : You might be able to find one of these bluetooth dongles at auto parts stores or Harbor Freight maybe.. things like that. Then you need the app loaded on your phone. But in the meantime if that's not successful you could still order it online and then if the others don't do what you need then you could return it.

I agree but my point was I posted the link yesterday. Amazon most likely would have had it to him today or tomorrow. If an OBDII BT dongle is sold locally anywhere I would be shocked.
