    08 Prius charged cv axles, inner and outer tie Rods, sway bar links, lower ball joints, new plugs and coils last year, hubs, oil change and transmission fluid change and hybrid battery it’s showing 45.5mpg and I’ve gone 90 miles and used a half tank fuel, check engine is on for an evap leak small.

    What can I be missing that I’m getting such bad gas mileage? It does seem to take more effort going up hills and I hear what sounds like a rattling noise when I hit bumps or holes

    How many miles on the vehicle, and is the HV battery still an untouched OEM?

    it’s showing 45.5mpg and I’ve gone 90 miles and used a half tank fuel,

    Something is off here.
    The car thinks it's getting 45.5 mpg due to its calculations of fuel usage using the injectors.
    You've driven 90 miles, which should be ~2 gallons of fuel, based on computer.
    But, you're saying you've actually used 4 or 5 gallons.

    I see a couple options.
    1. Your fuel gauge is way off
    2. You have a significant fuel leak somewhere (mpg calc doesn't take into account fuel that may be pissing out of a hole)

    If you refill the tank does it take 4 gallons or something less?
