A pillar creaks noises.
 

I have a 2019 SEL Plus Tucson Htrac with 7,900 miles and about two months ago started make noise like creaking sounds when I travel on an irregular road. I took to dealer and they do not know what is causing the noise. Someone has the same problem. Thanks in advance for any input greetings from Puerto Rico

Something that is often overlooked,
Weather stripping when dry or coated with something will produce some curious sounds and cause unnecessary concerns.
I had to learn this the hard way when I decided to spray some silicone around the door weatherstripping thinking it would be beneficial, produced noises that caused me to think my vehicle was coming apart. Rest assured I won't do that anymore.
