Should I be terrified?

Hi all. Got a “propulsion power is reduced” warning and a greyed out regenerative braking icon. Dealer told me they are going to take out the battery and they are “95% sure” it’s a battery issue covered under the warranty. If it’s not I’m terrified about cost for a repair. Fun side fact, I just paid off the car 3 days before the warning.

Should I be worried or do y’all think I’m covered. It’s a 2020 Bolt EV with 32k on it
