Hybrid System Warning and multiple other lights

I have a 2012 Prius that I bought at the beginning of the year , it was at 58,000. I drive a lot so I am now at 78,000 miles. Car has driven like a dream the entire time. I had driven my car to work like normal , but when I left and started my car I was met with a bunch of lights. Currently says Check Hybrid System , check engine light is on, my traction light is on, the master indicator, as well as the break system exclamation point light. The car starts and can drive . I drove it off home and while it drives it has trouble accelerating, you can tell it’s trying really hard, the breaks work but they feel a little “off” I can still stop but I felt like it was taking me longer to stop then normal. My car hasn’t been making any sounds, showing any signs of gas mileage issues or ANYTHING before I turned it on today. I bought my car from Carmax and have Max Care with them and will make an appointment in the morning. Unfortunately max care doesn’t cover anything HV battery related so I’m so worried it’s the battery even though I feel like it shouldn’t be with having less than 100,000 miles. Any thoughts? I don’t have a code reader but I’m sure I can borrow one from somewhere. Anything I should tell Carmax to look for ?

 

Hi y’all I’m coming back to this because I I ran a code reader on the vehicle.

I got P0A94 which is pointing to possible inverter issues ?

I have read some old posts on here saying that there is warranty on the inverter that was increased to 15 years. Is this true ? I have an appointment with the dealership on Monday.
