i have 2018 sorento LSX. it is 8 months old, with 17000 km. the rear muffler just before the exhaust tip is quite rusty and looks terrible. is this common , does anyone think that warranty might cover it?
Well, I'd read the warranty manual first for your answer.
Reason I say that, is manufacturer's have been getting really shady as of late with what is and isn't covered, particularly on underbody parts exposed to Mother Nature's elements, like an exhaust system.
I am going to say they will not replace it. Here's why. Is the vehicle quiet ? Are the emissions correct ? Is the vehicle unsafe. No is probably the answer to the questions, and the minor cosmetic surface corrosion you are seeing, will be dismissed by KIA as being expected and normal for that type of use.
