DIY Cruise Control FAQ (2006-2010 Yaris) - Toyota Yaris Forums

Well I had a pretty scary experience tonight. I installed cruise control with the OEM stalk a few (I think) months ago and it's worked flawlessly up until tonight. It was humid and raining which I think may have caused it?

Anyway, at first CC wouldn't work at all. I fiddled with the stalk a few times on the drive and eventually it turned on. All was well for a couple minutes, until I starting hearing the engine rev and noticed I was going 90MPH (I set it to about 65). It was like the cruise control stalk was stuck in the up position (it wasn't). It did this several times while also cutting out and not working several times during my 30 minute trip. I was obviously watching it very closely after it happened the first time.

Not sure what the cause could be. I'm guessing a loose wire or something? Anyway, extremely unsafe either way and a big notice to anyone out there to be sure to know what they're doing.
