    What code reader did you use to get those codes?

    Have you checked the engine air filter to see if it is dirty?

    They are from a dealers record of a prime I’m about to buy today. I have no idea what hot soak means. I assume no start means it doesn’t start? I’m not sure to be honest

    It sounds to me like the previous owner let it sit in the sun on a very hot day and the traction battery got so hot that the car would not let it start up. If so, that's not good for the battery at all. Since it says it's intermittent, that suggests it has happened multiple times. This is definitely something to investigate. It's something I have never experienced here in FL. But I don't think I've ever let it sit all day in the summer sun without a windshield sun shade.

    how many miles on her?

    i can't imagine how dirty an air filter would have to be to throw a code. the engine must have been starved for air

    According to the source of all knowledge (Google) it sounds like on more than one occasion the engine was hot and did not start as opposed to the engine being cold and not starting? The reference to a dirty air filter is sort of self explanatory? I had a engine not start on my Gen 2 many years ago and it was fixed with a firmware update. No wrenches required. As suggested above, check the air filter and see if it needs replacing if it hasn't been recently.

    Toyota had a TIS regarding this error... it's another car, but I am sure the reason is similar...

    Never would have guessed that a camshaft position sensor would cause a "Hot Soak" condition....

    Battery? Sure.
    Fuel system? (Vapor lock) Yeah.

    Ya learn something new (though seemingly illogical) every day.

    If it doesn't give a good position signal when it's hot, well, there's a hot-soak no-start. :)

    Fuel system vapor lock was more of a thing in the days of fuel pumps that lived on the engine, and sucked the fuel from the tank.

    Now they live in the tank, and push the fuel to the engine. Hard to vapor-lock that.
