My boyfriend just bought a used 2017 EX and since I am the "car person" in the relationship, he asked me to look at it when he started hearing a noise. It looks like the splash guard on the passenger side is rubbing against the tire because a screw came out. Easy fix. But, I went to compare it to the driver side and the driver side doesn't have a splash guard at all. I've been reading through here and it seems like the only benefit is to keep down the amount of dirt and mud that splashes up onto the car. Are there any other reasons to have these installed? Are they necessary or beneficial in any other way? We live in the south and don't have to deal with salted or sanded roads. Thanks for any advice you can offer!
