This is a strange law.

.... The California-spec warranty does not allow for degradation of the battery’s capacity. If it’s not performing to “the highest standard” — that is, as new — during the warranty period, G.M. must repair or replace it, according to David Clegern, a spokesman for the California Air Resources Board.'

All Li-ion powered products have some degradation.
The fact that a PHEV can hide any degradation makes this law work.
PHEV's use a portion of the battery's capacity in the middle and can mask any degradation for a long time.

How does this law work with BEV's?

As always, it's wintertime. Wait for spring before getting bummed with your ELR !!

Also as the car is new to you, in addition to waiting for warmer weather (25 miles in winter is pretty normal) give it a few charge/discharge cycles as the previous owner may not have been driving in the most efficient manner.

Yeah wait until summer. Honestly the most I have gotten from my used my14 28k ELR is about 40 miles once. It's usually 38 range. Also it pulls more from the battery pack 12.5kwh. Ironically whoever owned the car prior to me did not use the gas generator too much. I think the first time I filled the tank it showed a range of 150 miles. Much better now and closer to 300m after being used properly. So don't trust the gauges too much until it learns your driving habits

My 2014 fell into the 25mi range when it was cold. Even here in sunny Texas!

As others have said, warm weather is your friend for range.

BTW, GM has never had to replace a battery pack for degradation. They are well designed. Your's would be the first that I am aware of.
