Why is my Kia Niro's engine making a strange noise?

I recently purchased a Kia Niro and I've noticed that the engine has been making a strange noise. It's a high-pitched whining sound that only happens when the car is in motion. What could be causing this and should I be concerned?

It sounds like you may have a problem with your transmission. I would recommend taking your car to a certified mechanic as soon as possible for a diagnostic test.

It could be an issue with your exhaust system. Check for any holes or leaks in the pipes and muffler. If the noise is coming from the front of the car, it may be a loose or damaged heat shield. Make sure to have it repaired before it causes any further damage.

Have you recently changed your oil? It could be a sign that it's time for an oil change or that you need to use a different type of oil. Check your owner's manual for the recommended oil for your specific Kia Niro model.
