Hi Scotty, I have a 2010 Prius that is getting intermittent ABS, traction control, and brake dashboard lights. they come on all at once, and this lasts for a few miles, but it goes back off for a day or 2 until it happens again. A local mechanic said they couldn't read the codes, so I took it to a dealer, who said there were no codes for brakes at all, but of course he wanted to sell me an ignition system and brake fluid flush for 200 each. I know there is something special you have to do to read the brake computer, but the dealer acts like there isn't anything they can do but recommend unneeded services. Can you send me in the right direction? If I can't get the dealer to figure it out, where can I go?
Check your brake fluid level in the reservoir.
they would have topped it off
do not top it off if it's above the minimum line

Thanks @doc the car is with my son's mother currently, but I can have her check. However, they were able to talk her into a brake pad change, so i'm assuming (maybe stupidly) that they would have topped it off then.
Turns out the issue was https://www.tsbsearch.com/Toyota/T-SB-0079-18. Replace ABS actuator and master cylinder. It's a known issue for prius. 3k to replace. Ouch.
