I had this problem with the rear shade on my 2016 36CKTS after about 2 months. Talked to the shade manufacturer and they sent me a replacement spring assembly for the shade. Unfortunately, it was the wrong part. When I disassembled the shade, I found a small aluminum pin that was supposed to be press fit into the spring end housing had come out. I was able to reinsert the pin and do a better job of getting a good press fit. Problem solved. Shade now works as intended.
