Hi,
Yes, I've owned one since June 2008 and have almost 50,000 Km's on her.

Three starters, Front brakes (ABS) and front fork chatter under braking.
All under warranty and have had the front brakes, and rotors replaced twice. Still not resolved.
Custom paint is now flaking off the front fender and gas tanks in chunks. Size of quarters!

Chrome plating is pealing and falling off badging, foot controls etc...
Rim's are severely pitted.
Bike is washed, waxed and maintained regularly. I ride her hard and make sure she gets the best, no exceptions!
Maintenance and serviced at dealership with all the receipts to prove it!
For a FlagShip bike that is supposed to epitomize the best of Harley Davidson parts, paints, accessories and components - 4 years later I am seriously wondering what Harley Davidson is doing and why the CVO's are deteriorating in such a cheap and poor fashion. What happen to quality? Gone... Sad but true!
My riding buddies 2003 Road Glide is pristine compared to my 08 SERK, we are both dumb founded at the condition of my 2008 Screamin Eagle Road King.
If you can purchase through a dealership and get an extended warranty - DO IT!
Also see if the chrome and paint is covered too.
Best, Michael
