Brand New Owner w Newbie Question

NO. You don't have NEARLY enough information to jump to that conclusion.
Under many circumstances, the system will keep the charge level in the middle somewhere.

 

Does the displayed charge drop/climb quickly? If it's gradual, I think it's less likely to be problematic, just due to driving conditions.

If you're driving on level roads, say 30~35 mph, engine fully warmed, the car will tend to slip into electric-only, and will happily eat up the charge. If this goes on more than a mile, you'll run it down to two bars easily.

Another scenario: you're tooling around a parking lot, looking for a spot. Here again you're pretty much level, and the low speeds (basically crawling) means you'll almost for sure be electric-only, and will eat up the charge fast.

If you're driving again around 30~35, but more stop-and-go, encountering traffic lights, stops, there's curves, rises and descents, then the engine will tend to stay on more, you'll just have brief electric-only stretches, and the charge should settle in somewhere around 2/3.

If you take it for a highway drive, say 50 mph or more, the car will never be electric-only (the upper threshold is something like 45). In that condition, after 10~15 minutes driving, if the battery is ok the charge display should for sure be up around the 2/3 level or better.

I would just give it a while, continue to monitor, and post updates. You might also look into a phone app Dr Prius (you need a bluetooth OBD adapter too, Carista is one that works), see what it says.

 

congrats and welcome!

doesn't sound to bad, but it might be a good time to purchase a hybrid automotive grid charger and start rejuvinating the pack.

all the best!

 

also:

consider cleaning the hybrid fan and changing the tranny fluid, along with regular maintenance for that many years.

You have a lot of things to check. Look at doing all the previous replies. My question is, Who did you buy it from and what previous maintenance has been done?
