•I had a strange failure with my 2014 Prius: Brake lights would not turn off.
•Started occasionally but became more frequent until the brake lights would not turn off.
•Investigation found the switch pressure plate was bent.
•Fix: pliers, bend the pressure plate to better engage the switch.
•Still not sure how the pressure plate got bent in the first place. Bend probably got worse when I slammed the break pedal on and off to try to re-set the stuck break light.
•Cost: Several hours of troubleshooting, headache, frustration and $0. I will call that a ‘WIN’!
