First, I want to see if anyone has rattle at the back??? Check your rear middle seat belt!!!
Make sure the rear middle seat belt's metal clip is fully secure to the magnet!!!!
Also, some annoying things I have on my 172 MK2
1) We only have one dealer and the parts are expensive!!
2) The surface of the intake manifold is impossible to clean.
3) Wind noise
4) Other Clio 172 owner will get close to me to look in detail how come mine is "Lutecia Cup". (Clio is rare in my country)
5) Big steering wheel, I want to change it to Momo, but I want airbag.
6) The door trim rubber area (where the window switch locate) always got dusty. Its material is a bit sticky.
7) passenger seat is a bit hard to fold forward, I need to use a trick on the handle (pull back and lift up/ or adjust the back panel a little bit)
8) I love my Clio too much and I love every min I drive it, I hate to see the mileage counter keep increasing
