ABS light on on other Prius years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2016.
What this problem usually is
This is the narrower sheet inside brake problems for the anti-lock brake (ABS) warning light. What separates it from the wider brake sheet is that most owners here aren't describing worn pads or grinding. They're describing a light, and often a list of features that quit along with it.
What got replaced
Owners who name the part that was replaced mention the ABS pump (14 reports).

“The traction control, abs, and emergency brake light came on. We checked and the code produced was C1391. Thereâs a humming noise every 10 or so seconds when idle. The humming noise is also present when braking. We did some research and this appears to be an issue with Toyota Prius. We called the dealership and were informed that this was not a known issue. Thank you.”

“ABS, traction control, brake system, and brake lights turned on while driving. Took the car to the mechanic and pulled the code C1391. It seems from other complaints to NHTSA that it is a common issue and quite dangerous, meaning the brake system is failing.”

“The slip notification, abs, and brake lights turned on while driving on the highway. The brakes then became very stiff and the vehicle did not brake as fast or as well as it normally does without the lights.”

Should you keep driving it?
This page can't tell you that. 1 of 44 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
