Kia Troubleshooting Questions? Ask a Mechanic
Hello, Eddie here and I will do my best to help. What is the approximate mileage on the vehicle? And have you checked the oil level yet? Also, is the check engine light on now? or have you seen it come on since you've noticed this problem? thank you.
Alright, There is a rev limiter while in Park, so around 3800 rpm's or so, it will begin to cut out some. No check engine light tells me there is not likely a vacuum leak, where that air sucking noise could possibly be coming from, unless it is coming pre MAF sensor, I would look at the air box closely, make sure the air filter is clean, as a restriction could possibly cause that sound. This vehicle is still under the 10 year 100K miles Kia factory warranty, so if there is any tapping from the lifters, then I believe it would possibly be covered if a Kia dealer finds that there is a failure there. It's also possible it is in the CV joints or transmission. But usually with CV joints you notice a clicking noise more around turns as it stresses the joint more. Have you had a dealer look at it yet? With this kind of noise, I would request going for a ride with the service writer or tech if possible to show them exactly what your hearing.
Absolutely, thank you. If there is a failure that is coverable, then I feel you have a good chance at getting it covered under powertrain warranty. Thank you, and let me know if you have any further questions.
Why you would want to fix it yourself if it could be covered under warranty seems odd to me, but I will opt out. Thank you.
