2014 prius V5 30mpg

welcome!
hmmm, that's a tough one. do you have the history of the car? might it have been in an accident?

tell s about your driving conditions and hvac use.

 

Where do you live , what has the temperature been ,, mpg drops in the cold weather

 

These cars can get 36 mpg at 85 mph and certainly the epa 41/42 mpg at normal speeds. I might look at the brakes and see if they are dragging. Check the air filter and make sure it's not clogged. Maybe a clogged catalytic converter but I would think you would get a check engine. I assume no lights are on indicating some engine codes.
Compare Original and New Fuel Economy Estimates

 

To give us more clues, start with this questionnaire:
Fuel economy complaints/queries? Please copy, paste & answer these questions, esp. if you're new | PriusChat

The biggest thing missing from that list is brake drag, which will also show up as unusually warm wheel hubs.

 

1. Compute your MPG by hand, not using the car's computer display. More accurate across multiple tanks.
2. Set the display to instantaneous readouts of MPG and observe. In what circumstances does the readout seem low? Up hills, down hills, accelerating, at constant speed? What is the speed that seems to display 42 MPG?
3. Where are you located? What sort of trips? Long cruises? Short? Hot? Cold?

Lets see if we can get any clues.

 

If you exhaust all the good ideas that the above forum members listed, pull your spark plugs & do a compression test
on your motor.

For comparison, my son has a 2015 Prius v 5 and says he averages 42 mpg US in the foothills of the Blue Ridge Mountains.

Is that a typo or does the car only have 28K miles? That is extremely low!

 

what brand and model tires?

do you drive her hard and put her up wet?

 

The larger question is what model dryer does @bisco recommend?
Or, what alternative car for rain or snow?

 

I'm getting 42 / 44 most of the time and I have well over 250,000

 

My 2013 V with almost 70K miles has lifetime average of over 47 (actual fill-up calculated) MPG. The only time mine falls below 40 MPG is during near or sub zero F temperatures during the (Minnesota) winter. With warmer 50-60F spring temps right now I'm getting over 50MPG.

 

U have a picture of that?

 

Might depend what inverter firmware the cars have. Just got mine back from 3rd update my mileage is down.

 

According to your profile you must have the only AWD-e Prius v in existence. I do not think Toyota had even invented that in 2013.

My son’s Prius v has never had any firmware updates that I remember. He only gets that if due to a recall.

 

I don't know what year his prius is but there have been three to try and protect the inverter that will blow.
When the inverter blows they might get a bit tense without the updates.
Have him run his vin through the toyota site.

 

It is a 2015 Prius v.

 

What do you want a picture of? My Fuelly icon is accurate and I have entered every fill-up since I bought the car in Jan 2015.
