    On February 27, 2014, I changed the oil, filter and cabin air filter at the dealer where I bought my Kia, but for some reason, the gas mileage has dropped significantly since then. The average MPG for the Kia Optima, Forte, Sedona and Sportage is between 30-33. As of March 17, 2014, My Kia just barely gets 25 MPG. I switched to the highest grade of gasoline gas soon as the MPG began diminishing--no improvement. What precisely is responsible for the dramatic loss in fuel economy? Virtually all Kias have an excellent reputation for its high MPG. What else could cause gas mileage loss?

This could be a timing belt as well. have they looked at that as possibility. Sometimes the belt just jumps teeth causing it to still run just not correct.

What I can tell you, is to get the car out of the dealership

trans shop,unless money means nothing

2002 Kia Optima runs great, transmission has started acting irradcally. it will shift and pull in gear for a short time after starting, but after a few minutes it fails to move the car. I've changed...

Keep driving it like that & it won't work at all

When ever you even think you have a transmission
issue,you immediately stop using the vehicle or you
end up rebuilding the trans,your call,your money & lots of it

Ask yourself ---Why would changing the fluid do anything?

Old oil out / New oil in ?

You change trans fluid because it breaks down from the heat
That is it's job,to remove heat or your trans fails

Trans & Power Steering get changed every 3 years & not
over 30,000 miles ever on ALL Vehicles

Where is the speed sensor control module located on 2002 kia optima?

The speed sensor module is AKA "throttle control unit" on the throttle body. This is what controls your accelerator. Your vehicle does not have throttle linkage or a throttle cable if it is equipped with one of these.

2001 Kia Optima acceleration drop out problem

I would have them check the Sensor that is located on top of the transmission, I had a similar problem back when I bought mine. And I was told that the sensor was Bad, and there was a recall on it and it is a common problem. Because of where the Sensor is located it is a pain to get to, they have to drop the transmission. So for me anyways instead of just dropping the transmission to swap out the sensor, the Kia dealership that we bought the car from Replaced the whole Transmission/Sensor with a brand new Tranny. I have over 160,000 miles on the Car now and I have had no problems since.
