    I have a 2020 tundra there is a knock when I leave but only during the first start after they do not. if I stop it will do it again. I think all trucks do it .. do you have any idea who could do that

    In progress…
    If you’re talking about a noise/thump when you first take off after cranking up, it’s an ABS self-check. Perfectly normal.

    ABS modulator self-test, and yes, it’s normal.

    If you ever hear your “fuel pump” running a few hours after you’ve shut the truck off, that’s also normal. It’s actually a pump testing the fuel system for vapour leaks.
