Why is my Kia Sorento making a rattling noise while accelerating?

I have a 2016 Kia Sorento and I've noticed a loud rattling noise whenever I accelerate. It's especially noticeable when driving up hills. What could be causing this and should I be concerned?

It's possible that the rattling noise is coming from the exhaust system. Have a mechanic check for any loose or damaged components and have them repaired if necessary.

Another potential cause could be a loose heat shield. This is a common issue with Kia Sorentos and can be easily fixed by tightening or replacing the heat shield.

If the rattling noise is accompanied by a lack of power or jerking while accelerating, it could be a sign of a problem with the transmission. It's best to have this checked by a professional as soon as possible.
