I've had mine since September, and I use it often (both cover, and roof) and I've had zero issues. It's butter smooth, and people who get in the car at night are quite amazed at the display.

On my old F25 X3 the roof was creaking when driving. I got used to it after having them try to fix it about 3 times, it only happened between about 5C and 15C or so, but never had a mecanical problem with it. Only "problem" is that after 7 years the mesh diffuser thing was absolutely fitthy and I never managed to find a 'safe' way to clean it!

Oh, on the F25 if you had it opened "all the way" (open it once, then twice) you had to partly open the back windows otherwise the infrasounds would make your ear bleed. The G05 doesn't have that problem.
