The warning lights just flashed up again re my master break cylinder not responding correctly on my 2012 Prius C 3 I've replaced it with 2 previous used master cylinders in the past. I'm considering buying a new one instead of used but I'm worried the warning lights will come on again because of the possible issue being connected to the master cylinder. Is it just a coincidence that my 3rd one is failing or could the issue be something else? Like improper instalation etc? I do use cruise control a LOT.
Have you retrieved the trouble codes, any one of these times, to find out what the system is trying to tell you about? If you do not have a scan tool to do that, there is this way: Blink (a/k/a Flash) Codes – How to. | PriusChat
