We bought our Rio Kia 2014 model by swan motors in Vereeniging two years back,but we have a problem and defnitely a manufacturing problem,on the right side of the roof the paint is peeling and gloss painting is fading and looks really ugly we were already by panelbeaters and good painting workshops and said it is defnitely a manufacturing problem,this is getting worser and the people who are also driving kia Rio is asking what is the mark on the car,really its a brilliant car but the paint work cant give problems after 4 years? We are really looking for answers and we paid a lot for the car?
