We had grinding noise and very slow operation, and eventually failure to slide out on our 2011 DS. Dealer replaced motors, failed, replaced motors again and synchronizes, failed again, replaced bent shaft and gears, ok now except for poor fit at bottom/rear of slide. Too many days and weeks spent on this bad design. Missed months of use. Hope it's been redesigned for you.
