My 2011 started doing this at about 2 years old! it is a pain in the butt! The dealership said this cannot happen as it is a 1 piece pressed together piece. HAH! They were happy to order a new piece for me but I never got around to putting it on, it's been hanging on my wall for 8 -10 years. it wasn't big deal to just snap old one back when it fell off. And it looked like more work to pull old one off seeing it has a spring wrapped around it........however now my grandkids are starting to drive it and they do not know how to put it backon.. I was going to do it today question is is there an easy way to keep spring in place so it doesn't lose it's tension when you remove it? No time like procrastinating for 8 to 10 years
