Tell them to charge it up to 100% and let it sit for a week surrounded by other cars. If they are brazen enough to sell this recalled car, they can stress test it a little for you.

I'm curious whether the dealership has you sign off on the fire risk.

OP: Why are you focusing on battery capacity degradation ?

This can be an indication of one bad cell group.

It doesn't happen that way

Yes but it could take a year to get a new battery and I would rather start with a car that is not already having an obvious problem that increases it's risk of a fire.

Change that to 3+ years

There is no obvious problem to identify fire risk. That is the issue in a nutshell. If you are buying a Bolt because you think you are smarter than the average bear and can buy a safer Bolt, you should learn more first.

If the car has one cell group with less capacity than the rest, the maximum range will be reduced.

Pack voltage at max range in a normal pack is around 400 volts. A weak cell group of the sort that GM hoped would indicate an at risk cell for fire may be 5 - 50 milliVolts lower than the average cell when fully charged.

Go ahead, guess the difference in range of a pack at 399.975 Volts compared to 400. And just for giggles, I'll point out that the average variation in pack voltage at full charge in normal packs is up to 300 - 500 mV

You are playing with fire. Good luck, because you need it.
