Kia Troubleshooting Questions? Ask a Mechanic
Hello I will help you with your question,
It sounds like you need to have the spark plugs changed and the well where they sit inspected for oil leakage. At the same time have the throttle body cleaned and that should take care of it. If the air filter has not been changed or the battery checked for health those should be done as well.
At about 60,000 miles you should have the transmission fluid exchanged only installing the correct Hyundai fluid. Accept nothing less and the shop should have a fluid exchange machine to do this task.
Those should take care of any issues that will come up in the next year or so.
Please let me know if you have further questions
I hope you are aware to have the timing belt done at 60,000 and I would do the drive belts at that same time. Regular brake checks each time the oil is replaced, coolant if not done in the last three years.
Let me know how i can help
