Help! My 2009 Prius base model had traction control flash all brake lights on and red triangle

So far I have had minimal issues with my car, I bought it last November. When I bought it there was a parasitic draw (maybe related???) on the hybrid battery that I fixed by replacing the Inverter, the tires also had to be replaced so it has 4 new ones that were put on early December. In early-ish January I got rear ended, caused minor damage to the bumper, I wasn't even going to fix it (properly) to be honest. Then when driving home the traction control came on, understandable since there was a ton of snow on the ground, and then all of the warning lights to do with the brakes came on my dash and it started to yell at me. I stopped in a parking lot nearby and turned the car off then back on, and the lights and noise went away (I thought/hoped it was a fluke). I drove it home, which was less than a mile away, and parked it overnight. I went out to start it the next day and the warning lights had come back and prevented the car from starting at all, at this point I called the insurance company the gal had and got my car completely fixed.
The only reason I mention the accident is this is the first time I saw this issue. Since my car has been fixed it has been running perfectly and I have had absolutely zero issues. But today when driving home I hit an apparently slippery patch of road and my traction control flashed and then it was normal, after about a second all the brake lights turned on again with the noise. When parking it outside my house, I was a block away when this happened, I turned it off and back on to see if it would resolve anything. And the red triangle was on as well as the car with the exclamation point on my touch screen.
As of right now the car starts, I have not tried to drive it at all so I don't know how long that will last. But I'm thinking this is a bit bigger of an issue that I originally thought it would be.
If anyone can help that would be fantastic, I'm in college right now and still do all my own car work. I have a certificate in automotive repair but don't know that much about hybrids. I don't exactly have the sort of money to send the car to a mechanics shop.
Anyways any help would be immensely appreciated.
