Replying to: sike00 (Feb 19, 2007 9:47 pm) If the dealer plays dumb,call KIA on the phone.You can find the number on their site www.kia.com.Reflashing seemed to solve the problem, although it took 3 months to get it done.Dont let them beat you down.Like you I feel very disappointed in the gas mileage on my 4 cyl Optima.On a long trip,it actually managed 31 MPG,but on mixed driving,some 80% highway had a low of 16.5, and usually in the very low 20s.I have a feeling that this car is not long for my garage.I have right now 3500 miles on it. BTW, keep your receipts,after three attempted repairs if a serious problem persists ,you are eligible for the lemon law.Look it up,Im not kidding.It might be a hassle and Im sure that they will resist mightily,but the law is on your side. If they deny the malfunction,take a video camcorder when you are traveling with a passenger,and videotape this occurrence ,making sure that the date shows on the video. This KIA owner seriously wishes I had bought a Hyundai Sonata which is a far superior car.On my 2006 Sonata,After 10000 miles I averaged over 28MPG.Thats for the 10000 miles,not just a tank.For my first 3000miles on the KIA I averaged 25.5.Thats 3 MPG less,although EPA says 34 hwy for Optima vs 33 MPG hwy for the Sonata.

I have been video taping it now for about 3 days, and I'm getting ready to take the car back,,,the bad part is they are 1 hr north of us,,,will definately look into the lemon laws,,,,thanks for your advice,,,greatly appreciated. Kinda sucks that I should be the one to have to tell them how to fix thier own cars........glad they're certified mechanics,,,hahahaha

Replying to: mickeyrom (Feb 20, 2007 7:23 am) I'm averaging about 23 mixed with my 'Bu Maxx. Note that the EPA for the Optima V-6 is just about the same but the experiences in the real world are probably worse. I stated going in that if I got the mileage in the Optima 4 a mpg or two higher than the Maxx I'd be a happy camper. |

Replying to: mickeyrom (Feb 20, 2007 7:23 am) I haven't taken my Kia back to the dealer yet, but my Hyundai experience indicated that was the weak link in the occasion. The sales experience was worse than the service experience, however. The sales experience deteriorated from my Elantra purchase in 2001 to my looking at a Sonata at the same dealer in 2006. |

| Does anyone find it odd that Kia does not include a MPG option in the display,,but does include an average for Miles per Hour. I wonder if they know that the mileage on their cars are all over the place,,,and if it we had displayed in front of us it would cause more issues as I assume they hope we wont sit down and actually figure it out by hand. I have 2 kia's,,,on 4 cyl and one 6,,, the 6 cylinder gets right at 20-22 mpg, and my 4 cyl will get anywhere from 18-28,,,hardly ever the same average twice. When I talked to the dealership service dept. about this they told me that with the mass airflow sensor and the ambient air temp sensor that when it is cold outside and the sensor is only seeing 16 degrees F. that the system never fully goes into closed loop operation but stays in open loop and causes it to use more fuel, since the computer thinks the car is cold. So it runs it more rich on the fuel even though the engine is up to temperature. Oh I miss the days of carburation. | |
