How do I troubleshoot a malfunctioning power liftgate on my Kia Sorento?

I recently bought a Kia Sorento and have been having issues with the power liftgate not functioning properly. Sometimes it won't open at all, other times it only opens halfway. What could be causing this issue and how can I fix it?

First, check the power liftgate fuse to make sure it hasn't blown. If that's not the issue, it could be a faulty sensor or motor. I recommend taking it to a trusted mechanic to have it checked out.

In my experience, this issue can also be caused by a weak or dead battery. Make sure your car battery is fully charged and try again. If the problem persists, it may be time to replace the battery.

Another thing to check is the power liftgate switch. It could be worn out or damaged, causing the issues you're experiencing. You can easily replace the switch yourself or have a mechanic do it for you.
