Starting about a year and a half ago, my Kia Sorento has sounded like there is something wrong with the suspension, as there are grinding/rattling noises when driving. It's especially noticeable when driving through town or going over bumps. I have taken it in 3 times to both a dealership and local mechanic that honors Allstate Warranty. They have replaced the struts and joints more than once and the sounds just come right back. No mechanic has been able to tell me what is going on as they don't know. Just one of those very annoying things I have to deal with, I guess.
