    Any help is greatly appreciated!!

    I own a 2010 Prius which was imported to PANAMA from USA 6 months ago.
    Has orginal engine, and parts etc.
    Car was in excellent working order.
    A bit of background:
    Car has just over 200K MILES.
    Before being exported can had:
    1. Regular scheduled maintenance.
    2. New Toyota hybrid battery installed
    3. New Toyota EGR system installed.
    4. Had regular servicing, fluids and filters.

    Car has had regular oil and filter changes 1x since being in PANAMA.

    PROBLEM: Car was being driven and hit HARD into a very deep pothole on right front wheel.
    Also hit under carriage on rim of pothole HARD.
    Car still drives, does not appear to be leaking any fluids. No white smoke, no oil exiting tailpipe, only carbon and bit of H2O.

    Engine is making terrible clunking noises and extreme vibrations (jumping around like a jack rabbit in a coyotes mouth!).

    I would greatly appreciate any ideas as to what is wrong with it before taking into repair shop.

    Please see video attached.
    Thank you for your help and consideration!

    Did all your problems happen after you hit the pothole? Or they are separate events?

    It seems like the car is misfiring. You should read the codes and see what clues it can give you.

    Do you know the miles that occurred at? Any other details, say why components were replaced? Any mention of the intake manifold (has EGR components).
    Always, just during cold-starts, or?
