Have a 21 Lonestar w/51k miles. I have not yet had the S/S issue but I think I may be heading towards it: When stopped, the restart sometimes gets a bit jerky, also it shudders a bit during shutdown. No warning lights. It only does this in the afternoon when I am leaving work after it sits for 9 hours. After 5 minutes, it functions normally. I get around this by disabling the S/S. It's OK in the morning regardless of temperature. It acts as though the belt may be slipping but I just want to be sure this is not a precursor to the failures described above as this started about 2 months ago. Otherwise, I have no issues with mine (knock on wood).
