While taking off from stop light engine started knocking. Pulled over ,no engine light on, oil ok, tried to drive home slowly as it didn’t knock going slow. Then engine quit. Towed to Kia dealer. They said it could be cause from sludge due to missing 10 oil changes. I said no they did first and last change and I have proof of oil changes and correct weight oil. A Kia mechanic at a different dealer told us there was a service recall on them. Called Kia they said it wasn’t for that engine. Waiting to see what dealer finds and if they fix it.
