    Weird one, and I can't say I remember when it started...
    Have a 2012 Toyota Tacoma PreRunner 2WD Double Cab Short Bed V6 Automatic.
    When I set CC, then signal to change lanes it immediately kills the CC.
    Doesn't matter if it's signal left or right. Lights on or off.
    I can snap the CC wand down and reengage the CC fairly quickly but it's annoying.
    I do a lot of California fwy driving and try not to be an A-hole so it's become a thing...

    I do have my light bar and a few fog light replacement lights wired to my brights.
    And I do have non-stock, replacement tail lights - LED.

    Curious if anyone has run into this before. THANKS!

    When you hit the brakes, it kills CC.
    I'm betting the aftermarket taillights have something to do with it.
    You may have a voltage leak in tail lights when you hit the turn signals?

    Have a buddy turn the turn signals off/on and look to see if you brake light comes on.
    it may be faint, of only happen fast. Look closely.

    Yep ^^

    I'm betting something is crossing over into the stoplight circuit somewhere.. like the taillights or trailer wiring. Do any of the turn signals fast-flash like a bad bulb? Any of them dimmer than normal when viewed from outside?

    It's kinda sketchy but you could try disconnecting each tail lamp housing and go for a quick drive to see if the problem goes away.
