All of the sudden those 3 lights turned on. Any ideas?

brake actuator, speed sensor, wheel bearing, wiring or plug to speed sensor and etc.

check your tires pressure. are all tires the same model and in good shape?

ultimately, the trouble codes tell the story

 

Responses like "thing, thing, thing or thing and etc." are common when those lights come on, because the number of possibilities is really closer to 200, and nobody really wants to type out that many things.

The usual suggested next step is to ask the car why it put those lights on. Then instead of throwing darts blindfolded into a pile of 200 things, we can start talking about what could be wrong with it.

You can ask using an OBD-II reader plugged into the diagnostic port under the dash, or by jumping two pins of that port with a wire and counting the blinks of the lights. Both methods get mentioned here pretty much every time a question like this is posted, so the details shouldn't be too hard to search up.

 

Do you have anything constantly plugged into the OBD port? That triggered similar symptoms for me, multiple times, with increasing frequency. Discontinued used of a ScanGauge II (plugs into OBD) and symptoms never returned. Dealership mechanic speculated the constant weight on OBD port was causing signal interuption.

FWIW mine also showed "Check Hybrid System" warning, each time.

And the weird work-to-rule brake feel.

 

As ChapmanF said, you need a code reader.
Invaluable piece of equipment.

My bet would be an ABS sensor. That is exactly what mine did.
Cruise wouldn't work, regenerative braking doesn't work either. That's why your brakes
don't work the same...
Get a code reader that reads ABS. About $50 and up depending on what you want.

 

yup, extended brake actuator warranty. common prius issue, along with a couple others
