#154 of 161 Poor Mileage that has nothing to do with driving technique by bobh001

Mar 08, 2010 (11:04 pm)

I have been reading these messages and I just want to know why a block of 2006 Sedonas have fair to great mileage while others suck.
I bought mine from CarMax 4 months ago. I since have been to the dealer 5 times.
The main computer had a problem with air bags and seat belt warnings. They reprogrammed the computer. Then the transmission slipped out of gear - or wouldn't engage. During this time I got ~ 11 mpg. Kia reprogrammed the transmission control unit - reset fuzzy logic to degault values and I got 19.5 mpg in city and highway. Over a couple of tanks mileage dropped to 11 --> 12 mpg.
Their programming or sensors have a problem in some vehicles causing lousy mileage.
 
I think their fuzzy logic or their sensor test programs stink. The Kia dealers say no codes - no problem - just low mpg.
 
  Any suggestions - Kia customer service accepted my Excel spread sheet detailing the history/driving conditions/mileage. Been two weeks with no response.
 
You won't convince me the driver makes the difference even though the service manager told me I was using truck tires and that is why my mileage stinks. Those tires also got 19+ mpg. I get about 19 mpg on highway.

Greetings bobh001,
 
It sounds like your van has some kind of mechanical or programming issue. Driving habits most definitely play a role in fuel mileage, as well as air temperature, road conditions, tire pressure, etc.
 
If you are not seeing any kind of improvement I would try to get Kia to test the vehicle themselves.
 
Good luck.

I clocked my mileage and found out that I had a combined mileage of 12.77mpg!!
On its worst day my 97 Chev half ton 4 wheel drive got over 13, usually 14 with a 5.7 liter V8- with old plugs.
Symptoms-comments:
Does the transmission down shift too much?
Apparently, if you don't run the air, mileage improves???
It was 110 in the shade yesterday in Las Vegas.
The dealer said that is all the mileage I can expect!
Then there is the smell of raw gas.
This is the venting system in action according to the dealer!
The dealer claims 17 in town and 23 on the highway?(got about 20)
Why do they publish such nonsense?

I have a Hyundai Entourage Limited (same as Sedona). I spent 3 days in Vegas during the heat wave (100+°) and never got less then 20mpg and never smelled gas. I completed a 5400 mile trip from Wisconsin to Calif. and back averaged 23.9 mpg using milage divided by gas purchased. I'm very happy with the results considering the weight and lack of aerodynamics of this vehicle

I have gotten 22.9 mpg highway but last weekend I pull my1000lb open trailer with only one motorcycle for a total weight of 1700lbs in it I was down to 13.9 highway. During the summer I had two bikes in it I had 15 mpg, with the two bikes and trailer I'm at 2400lbs.
 I know your not suppose to pull in overdrive, but some times you just have to, to get somekind of mileage out of it. I'm just glad the van has a 5 speed and not just a 4 speed.

My 2009 Rio 5 gets lousy mileage too. My previous car, 1990 Civic got around 33 mpg driving to work. Got only 22 mpg on my last tank (25/35 rating) with the Rio. Why doesn't our government enforce the gas mileage?

Just an update, now our 2007 Sedona van has over 50,000 miles on it and still is getting over 20 mpg highway. Even with the bad for mpg oxigenated feul we have an studded winter tires we got 22 mpg on a trip across the state at an average of 75 mph. There are 2 mountain passes in that average as well. No problems except an air bag light that needed something under warrenty, and a leaking oil filter after the GM dealer doubled up the o rings on the filter. It is making some power steering noise I think (could also be alternator), will try changing that fluid come spring with an additive and hope it goes away! Overall we are very satisfied with this van but seening as how they stopped making them, next van will be one of those new high power 2011 Caravans after they hit the used car market, cause I don't buy new!
