20 Most Recent 2016 Kia Optima Questions & Answers

Just my first thought. I would think the transmission might be slipping. Another thought if it has been setting a while wonder if you have brakes or emergency brake sticking. If they were sticking all the time you would be able to smell them. Maybe just sticking and release when the car gets moving. I know if transmission fluid is low it will cause them to slip also.
I will say I have never had a kia and the vehicle I know of say the transmission oil should be at a certain temperature to check level under the car on sealed transmission..(because oil expands at higher temparature.) The way I have seen you have to add fluid under the car also. So Kia is somewhat different.

You probably have a wheel, suspension or tie rod problem in the front end - you need to have it checked immediately by a shop.

This info should be in your owners manual.
The 4 speed trans shows a total fill of 8 quarts and the 5 speed shows a total fill of 10 quarts. Just changing the filter should be half that amount for each transmission.
There are trans fluids for multi-brands of import cars, Dextron may also work.
Again, check your owners manual or look on the dipstick.
