Hello,

I am hoping to get a WT model when they are available.
With this new Ultium battery technology, if there are issues with the battery in the future, does all of the battery need to be replaced, which I'm sure would be super expensive, or, is it made so that small sections of the battery may need replacing?
Not sure if the technology is made so that small sections fit together to make it work.
Just thinking about possible maintenance costs down the line. Thanks

If someone knows better, please correct me, but my understanding is they'd just need to replace the module that's problematic.
This is actually one of my favourite parts of GM's Ultium strategy - if they say its an Ultium car (the Bolt and Bolt EUV aren't, for instance), that means it uses common components, including a specific battery module design. So different Ultium EVs will have different sized battery packs, but they'll all be built using common battery modules (just different numbers of them -- more in the Hummer, less in the Equinox).
Hope that helps!

It has a wireless BMS so there’s much less wiring too. Supposedly when the new solid state batteries are available it will be possible to upgrade the modules in an ultium platform vehicle to the new chemistry. This is all stuff claimed by GM engineers, it really does seem like their battery tech Is going to be ahead both in the overall ultium platform and the current battery chemistry. Maybe this is the turning point where the batteries aren’t such a problem and could in fact be improved down the line.

That does sound very promising. Thanks for these replies, it gives me a lot more motivation for the investment.
