Consumer Description

Oil consumption issue. My mechanic referred me to Kia because oil consumption. I would bring car in because oil light and no oil in car and had oil change only 1000 miles. Kia did 2 checks one at 1000 miles and one at 500 miles and oil consumption failed both times. Now I have to pay $686 for oil combustion cleaning even though I am being told this is more than likely going to have engine replaced by Kia because of known issues,
