Chevy Volt High Voltage Battery problems do not bode well for the Bolts

My dad has a 2017 Volt. For a few months last year he was getting the well-known 'shift into park' warning. This April he took it to the dealer to that that fixed. GM has a service bulletin and everything. It is still at the dealer and he's not getting is back any time soon!

When he brought it in they ran their diagnostic software and found a problem with the high voltage battery. They refused to release the car back to him and said the battery will be replaced under warranty, and the battery should be there in a month. Well, it's still not in.

So I called GM's Concierge service and spoke with a nice person there that had ZERO information about when - or even if - a Volt battery would ever be available. Because I was nice and not being mean to her she put me on hold and called a dealer she knows that likes her. What she told me was very interesting.

There is no new High Voltage battery part number in the GM parts database. They don't have any new batteries and they are not making any more new Volt batteries, they do not exist. What the dealer did tell here is that there is a GM parts database entry for a refurbished battery, put it has no ship date and is listed as a future product. She was told by the dealer that GM is taking old Volt batteries and swapping out the bad module with a module from a different Volt battery! Some day those batteries will ship, but no one knows when.

Meanwhile, the dealer that had offered $11,500 trade in value says that is now down to 10,000 and dropping every day it sits on their lot, having waited four months already for a battery that they can't say when it will ship. Basically, the car is lost $400/month, undriveable, waiting for parts.

GM has moved on from this series. They are selling Ultiums now and have no care for previous models. They are not about to spend money on old tech. This may very well mean they do the same thing with the Bolts, now that they are no longer made.

Has anyone had any problems in the last six months getting their Bolt battery replaced by GM?

Very old news here. The real mystery is why the GM and the dealership are slow-rolling this process. They've known for a long time now they can't do anything for a Volt with a failed traction battery. AFAIK, there haven't been any GM replacement Volt batteries for years now. The only resource is a couple of small garages which buy junked Volt batteries, test for the good cells and build one for about $5k, with a one year warranty.

However, the inference in the subject is problematic. Volt batteries have little-to-nothing in common with the Bolt battery; a problem there is not necessarily a problem here. However, agree, GM not supporting the Volt with replacement batteries has everything to do with the Bolt.

Odd that you say that, since the look pretty much the same with the cover off, just fewer modules. And swapping out modules is the same idea, whether Bolt or Volt.

And how is a future ship date 'very old news.'

The best figures I can find say there were 157,054 Volts sold in the US, and 177,000 globally, including Opel Ampera. For the Bolt, the US sales were 137,192, and globally, including the Opel Ampera E was 166,749.

So yeah, I think you can assume they will eventually be offering trade-ins for the new Ultium Bolt, or you will have to look to the small Volt specialty shops for refurbished Bolt batteries too.

Have you searched on what the law is on parts availability and warranty repairs? I may not have all the details but it sure looks like they have to be able to provide the parts and repair it in a reasonable amount of time or replace or buy back the vehicle.
Yes, GM is contractually obligated to repair Volts for the stated term of the warranties.

We have to know the state in which the car was purchased and in what state it is now registered, the date it was sold and the current mileage. The "CARB" state warranties are supposedly different than the lame state warranties. Basically, GM promised any Volt owner five warranty coverages:

1. Bumper to bumper: 3 years/36,000 miles
2. Powertrain: 5 years/100,000 miles
3. Sheet Metal corrosion: 3 years/36,000 miles, rust-through: 6 years/100,000 miles
4. Federal emissions major components: 8 years/80,000 miles
5. Voltec: 8 years/100,000 miles

It's the rare Volt which still has any warranty coverage remaining.

I heard there is no Volt packs being built. That was last year even.

GM doesn't have to give new pack, just fix bad cells.
And only for those still covered by the written warranty. They're under no legal obligation to maintain a supply of replacement batteries for those out of warranty. That's why Bolt owners should be watching the situation.

You have to go to 'developing nations' to find those.

I've mentioned this before, but I read a story of a guy who's Tesla was declared totaled by his insurance company and it was sold for salvage. 8 months later his Tesla app pings and his car was in Ukraine, fully repaired and driving around. Why can't we do this here???

Yes, however, I have been seeing news articles that trades are seeing growth because the MBAs that turned colleges into ATMs for the upper-admins in the 1990s have now priced them out of normal people's reach, so trades is the only option. And they look enticing because they are commanding high pay rates for their work - specifically because there aren't enough to go around. You can once again, earn a middle class income from the trades.

Exactly my point. Chevy not selling a critical replacement part for a vehicle less than ten years old seems wrong.

I mentioned that and they scoffed, "As if that would work. That would be a waste of money. You can't win against a dealership."

One more time. If an owner has a written warranty still in force, GM must repair the car or buy it back. If the warranty has expired, tough shite and he is on his own. He can go to the aftermarket, buy a rebuilt battery and pay to have it installed by an independent shop.

One more time, the mystery is why the dealership is holding the car they know they can't repair and why the owner is not taking matters in his own hands.

I have A 2017 bolt. I had the battery replaced last year after receiving the recall letter. Has your Dad had the battery replaced in the past or is this his first request for a battery replacement? I have not had the shift into park warning. Does this warning affect the driveability of the car?

There were 148,000+ Chevrolet Volt vehicles sold between 2011-2018 in two generations with different battery packs. There were over 200,000+ Chevrolet Bolt vehicles sold in one generation with essentially the same battery pack. You aren’t going to have trouble getting refurbished parts for your Bolt once it is out of warranty. If you live in a blue state, there are plenty of independent EV Shops that will work on your Bolt, so when it is out of warranty it will be okay. Meanwhile, if you are under warranty, then the manufacturer needs to repair it for free or replace your vehicle with another one.

I'll have to look into that. I haven't seen any yet around here, but it's a small rural state and EVs are 'brand new' to the mechanics shops nearest to me. Without looking into it, I'll bet there's one in my state and it's 230 miles away from me. ;)

Yes, exactly! It's a well known problem, GM has a service bulletin and I've been told that at most it's a $450 fix.

Even worse, I stopped by to get it's current mileage, borrowed the key from the service dept and it came right on ready to go. No warnings on the dash. Which jibes with what they said last April. THey don't want him to get stranded if the battery problem gets worse.

I think the best hope for long-term Bolt ownership is the 2026 Bolt EUV when it returns to production. Sure, there will be changes, but it isn’t a clean sheet design so quite a bit will inevitably carry over. Yes, the batteries will be different and almost certainly not interchangeable, but the more of the rest that is the same the more incentive there is to provide 3rd party battery solutions. It is one thing if a car is limited production and already likely to be doomed to an early grave by a minor component becoming unavailable, but quite another if those minor components are still in production.

I am having the same issue. My car has been at the dealership since June 2024. Initially I was told I’d likely hear something after the beginning of 2025. I have been told I’m on a list for a refurbished battery but there is no time frame. My dealership has been great providing me with a loaner car.
