I have a 2018 Sprinter, Synergy. I lost one piece to the rear cap due to normal traffic/use. I called Carefree Awning and they sent a replacement at no cost. The dealer installed it under warranty labor. However, the same thing happened again and when I called Carefree they stated that both front and rear caps were redesigned and they sent a replacement which the dealer again installed under warranty labor. You may have the defective older caps and if so, Carefree should replace them at no cost. Replace BOTH front set and rear set (all four pieces) as the entire cap has been redesigned.
