    We are seeing quite a few 2018 Tundra's with the PCS (Pre Collision System) Malfunction indicator on and code C1A10 being set. Also codes U023A , U1002 and U0235 can be stored. Just wondering if any other Tundra Owners out there have had this concern pop up. Thanks for letting us know.

    Yes my 2018 Tundra has the same problem. There’s a nation wide back order on the part! Oh joy

    There should be a TSB coming out on this soon.

    Yes, have same problem.
    My Tundra is at the dealer waiting to find out what's next.
    Did anyone got their fix or did Toyota have a fix for this already.
    Please share your thoughts. Thanks!

    I have been getting the PCS error since new and now have 11,000 miles on it. You can't use the cruise control when the error comes up. The dealer did a re-calibration and it was good for a day. My next service is at 15,000 and they said they would address it then.

    Yes, my 2018 limited has been doing the same thing. I have had it in the shop for the 4th time now. Toyota has replaced the sensor twice. Now the truck is just stopping on it's own. The PCS light came on then a triangle light comes on immediately afterwards. I believe I have a lemon
