Hi Rob,
Sadly they do....you may notice on the outside sort of centre towards the rear of the roof what looks like a rubbing /scratch mark (as i would descibe it) this is caused by a fold as the roof retracts as it lowers into the rear of the car , i have watched it retract and it can be seen doing this. I believe Chrysler are aware of this but dont or wont cover this under warranty ...as i believe it will happen again with a new one so comes down as a design flaw i guess ?...some owners in the States have also reported the rear windows coming away from the softtop itself but i dont know of it happening here, this could be in the southern part of the country where the weather is a lot hotter ?..but they are willing to cover this on earlier models only, do a search for more info.Some have reported issues with the micro switches that devide the boot space and the roof but i have never had a problem with mine summer or winter works fine.but please dont let this put you off this is my second Crossfire and i just love it ..different, quirky and not many around if you can go for the SRT 6 ... if you want any more info feel free to P M

Regards, Dave.
