I made a former complaint regarding oil consumption. I then brought my kia Forte5 in due to catastrophic engine failure & knocking (oil consumption was the symptom). It also had a rattling noise which we suspected may be the cat. Long story short, kia hasn't paid a dime for this, despite there being a recall which includes my VIN. The dealership has come up with every excuse in the book to not take responsibility. My short block may be repaired, but now they're saying I need to pay $2700 for a new cat & muffler. . . Which was damaged from the defective/recalled engine. The customer service at the dealership & consumer assistance center has been deplorable at best. This has been the most stressful experience. My car has been in their shop for over a month. They also are charger me for new spark plugs, even though I wouldn't have had to buy them right now if it weren't for the defective engine. Oh, the two-week late loaner they finally got to me? they decided to call me and tell me day-of that they were no longer covering it and would charge me $35/day - no warning. It doesn't take a rocket scientist to figure out that the engine failure caused systemic issues, which should more certainly be covered by kia.
