I just took the the 2000 sephia on a 400 mile trip and those rattles and bumps you feel driving back and forth to work seemed to really stand out. I think I need new shocks/struts, not sure which this has. One of my relatives had this done on a 00' sephia and as I remember she could only get it done at a dealership and it was relatively expensive. This was a couple years ago so maybe someone is making aftermarket suspension parts now. Does anyone have any experience with this problem? If I can get non OEM parts I can replace myself, if I need OEM my uncle work at a KIA dealership so... BTW 75,000 miles and very few other problems.
