    Hello all - Sorry if this has been addressed already. I did a quick search and didn't find what I was looking for.

    I have a 2017 Prime Advanced and occasionally there will be a drop in power after switching from the battery to gas. It doesn't happen immediately, probably a mile or two afterwards. I'm essentially flooring it (the meter thing will be in the red), and my speedometer will slowly drop. It doesn't drop as quickly as if I were to let my foot off the gas but drops enough where I feel I need to cut over to a slower lane until the acceleration kicks in again, usually a mile or so afterwards.

    Has anyone else experienced this?

    I think I would look at the common things ICE related.
    Bad/old gas.
    Gas filter dirty.
    How many miles on the beast?
    If you have a lot of miles maybe a set of plugs is in order?
    Injectors need cleaning?
    You get the idea.
    I wonder if it's throwing any codes that might give a clue as to what's going on.

    Just had my 120k mile oil change, and new plugs. I'll have the other suggestions checked out, thanks!

    if the battery happens to be low at that point, you won't get much out of the little engine, or it's hot out, the battery will be protected by the software, limiting discharge rate.
