serious mpg PROBLEM

[mjbRIO]

I bought my 2013 Kia Rio on October 31, 2012. Unfortunately, I bought it two days before it was announced that the mpg numbers had been overstated. Had the mpg numbers been changed prior to me buying my Rio I might have looked into buying another car. I have no problems with the new numbers and if my Rio came close to the new numbers I would be happy with my purchase...I guess. The real problem is that my Rio does not get even close to the new numbers in mileage and it is making me sick. From what I can tell the issue is mostly during idle and city driving. During city driving my Rio struggles to get 20+ mpg(tankfull). Last fillup showed me at 23mpg which was good for me. This tank is halfway gone and I have only traveled 60 miles. So I guess im on my way to having my first ever 120 mile tank of gas! my instant is showing me at 19.1 currently and usually the instant is about 2 points higher than real life for me. This is HORRIBLE! I should have bought a SUV! If I sit in my vehicle at idle for about ten minutes I can see the gas gauge drop and my instant drops insanely fast. I can go from 25mpg instant to 19mpg instant in a matter of minutes.

And for anyone wondering how I drive. I have driven it like a grandma for a whole tank, I have driven it like a racecar driver for a whole tank. It doesn't make a difference. CRAP gas mileage every time.

Anyone else having similar issues? I am going to take it into the dealer ASAP to have it checked out. There has to be something wrong.
I should not be struggling to hit 20mpg city in my Rio this is ridiculous.
the best mixed driving tankfull that I have seen in the last 2 months was 25mpg and that tankfull was mostly highway. I am so disappointed with my purchase I wish I could take it back. Hopefully this gets resolved.

To be honest with you I was wondering about this. When I first got my Kia Rio I downloaded a fuel economy app for my phone. I have been using it on every fill and noticed that the Kia's AVG for a tank of gas is always below what it should be according to the math.

That being said I have noticed idling isn't cutting down my fuel economy, which it should (Have Active ECO)... but I haven't read the instruction manual yet. Not sure if the Idle-Stop and Go works in temperatures below freezing or not.

I have had my 13 SX for a few weeks now. On my 3rd tank. I drive about 90% city and I'm averaging 29. Basically what it said on the sticker for city mileage. I don't drive in much traffic and about average amount of stop lights. I drive up a mountain bout 4 miles a day to go home (but coast down it when I'm leaving). I never use ECO mode and I drive a little on the spirited side. Do you live in a place with lot of stop lights and traffic or something?

During the break in period I averaged 29 about for city and 37 highway. And around those numbers till about 3000 miles. After that the mleage just fell off more and more. Yes there is a lot of stop lights but I got like 27 29 city with it when it was brand new...not anymore though. I'm worried kia will say nothing is wrong with it. I sure hope not. I changed the oil at 4300 miles because I hoped maybe it would help. It did not. The oil was black and the car sounded funny. Kia informed me that they don't recommend oil change till 7500 miles. Who really knows all I know is my Rio sucks gas...alot of gas.

Hi. This issue has been covered and discussed a zillion times. I for one was badly disappointed with the mileage of my EX 2012. In order for not hating that car -MPG wise cause almost everything else is to my liking- I forced myself to stop putting interest and passion in the MPG (in L/100km) for my case. Reading all that can be read on the subject of Rios poor MPG, I came to the conclusion the Rio with its tiny 1.6 GDI engine is not and cannot have the mileage we were told it would have. I too think the new numbers from Kia/Hyundai are still too optimistic. In the real world, it's more like 20-25 mpg/city and 30-35 mpg/highway. Numbers I achieve easily but are way too much for such a small displacement engine. Soon the Rio will make place for a bigger car with a bigger engine -it can even be the new Forte- something tells me the MPG will even be better. BTW, you can read the same comments on any Accent forum. For me, the 1.6 GDI is a top world leading high tech engine but not the most efficient when it comes to fuel consumption. If I can be proven wrong, I'm waiting for it...

I love this little kia and what i bought for as i needed a small little city car... Butholy smokes i literally laughed out loud when i read this line. I hope your right as i bought this car to hoepfully be my next rust bucket in 20 years..... But there are so many other engine head and shoulders above.

But amyways, im not wanting to start a war on emgines, but this care for what is is and the features you get for the cost are pretty good.

Cheers

For the original poster.... If you can witness a drop in your feul gauge over 10 mimutes of idling, you are definately seeing something wrong with your injection.

Glad I made you laugh out loud. As I said and said on the topic of fuel consumption: there are those who don't care about MPG and those who care regardless of the Wow of the little Rio. I love my Rio and wouldn't trade it for my brother's in law Fiesta who adds most of the time 5-6 mpg to my own numbers. Same driving give or take. Not because the Rio is a small tech marvel with ton of equipment that you have to close your eyes on its weaknesses which is fuel consumption. But too many Rio and Accent owners complain regularly on poor mpg. As I said: you get used to it cause all the rest is...Wow!
