GM to Replace Batteries in Recalled Chevy Bolts

Dealerships are scheduled in mid-October to begin fixing Chevrolet Bolts that were recalled for fire risk, although many owners of the electric car likely will have to wait months.

For anyone wondering why it will take until mid October for them to start shipping. Making these battery cells actually takes over 20 days, can't remember the exact number. I do remember they spend 14 days in a single room being tested before they are sent out to be put into modules.

They achieved it faster than I thought.
Finally some good news in the Bolt E(U)V realm.

Similar story. Also says that diagnostic software will be available in 60 days - needs dealer installation. IMO - the story seems to indicate that if the diagnostic software doesn't detect problems, you can go back to full charge. Not sure what that will mean for a battery replacement though.

Furthermore, the automaker also announced a new diagnostic software to launch in the next 60 days:

“The diagnostic software will be designed to detect specific abnormalities that might indicate a damaged battery in Bolt EVs and EUVs by monitoring the battery performance; alerting customers of any anomalies; and prioritizing damaged battery modules for replacement. It is GM’s intent that further diagnostic software will allow customers to return to a 100 percent state of charge once all diagnostic processes are complete.”

So, maybe enhanced diagnostics above what they implemented in the last round?

Seems pretty positive, accelerated cell production, interim mitigation, and some comfort if the diagnostics are useful. Adds to my belief it is worth waiting out the storm.

Yeah it was funny I was just talking with a friend about this and happened upon the electrek article.

Yeah, I like the idea of enhanced diagnostics. I mean even if the issues isn't present more diagnostics can't hurt and could catch something unrelated perhaps.

I don't think they are saying it is a 100% solution, I mean if it was I doubt they would still be replacing the battery modules.

If the issues are not present (assuming this is true for the majority of Bolts), added "assurance" will settle some nerves.

Still, it will take time to roll out the final fix. I have shared all of this with my local EV club, even Tesla owners are jealous that we will be getting more capacity, new warranty. Now let's hope they can get us in without too much delay!

Agreed! The idea that owners will be able to expand their range while waiting for parts may go a long way to making this bearable in the meantime.

I'm certainly curious how much extra capacity they are adding. The press release mentions it will take months to get all the parts to owners, makes me think it must be a substantial amount of capacity.

I wonder once these enhanced diagnostics are out, will they resume sale of existing Bolt/EUV inventory on dealer lots?

The capacity bump will be pre-2020 models, 60 > 66kWh due to the newer cell chemistry. 2020+ wont get a bump in capacity, just new cells\modules to ensure "defect-free".

In GM's last dealer communication video, they mentioned that "lifting the stop sale" was one of their priorities, so maybe it will allow for vehicles to be sold in the interim. But that is a big jump, since typically the NHTSA requires a recall's completion before lifting a stop sale order.
