I bought my 2015 Sonata SE with 30,000 miles about two months back. I now have it up to almost 36,000 miles and have noticed a slight rattle in the passenger side door. It happens when I listen to music with a lot of bass, and also when I hit cracks or potholes in the road. Any suggestions on how to fix this without having to go to the dealer and wait a lifetime to have them fix it? I bought it certified pre owned and have all of the warranties still, but don’t feel like waiting hours for them to look at it.
