Received a letter from KIA Headquarters stating a recall for piston oil rings and possibly engine failure. Inspection and software updates would take 1-2 hours, if replacing engine 8 or more hours. I made my appointment for today, arrived at Jone KIA in Bel Air, MD and am told that the letter is incorrect and I need to either leave my vehicle with them or reschedule. How many of the letters went out to owners and then we are told differently!
