Everything breaks, even the fanatecs do the same.
The only problem i've experienced was my shifter, which has broken twice. Im now out of warranty so i might have to buy a new G25 (IF ANYONE IN THE UK HAS A G25 SHIFTER FOR SALE, PM ME PLEASE! ). Another problem i had was about a year ago. My clutch pedal was acting irratic. I was'nt pressing it, yet the bars in the game was going crazy and my clutch was engaging/disengaging. I gave the clutch pedal a good beating and its never done it since!
