Happened to me a couple times too. But it turned out that I was closing the cover "gently" because I was babying the new tonneau.So this has happened three times to me now. After driving, the tonneau cover opens part of the way. I believe this is from any bumps or going into parking lots. Is there any adjustment for how the cover latches to get it more secure?
Same here. I heard it roll open on a commute to work. When I got home that night I noticed if you “baby it” shut, it doesn’t fully engage the locking pins on the side rails.Happened to me a couple times too. But it turned out that I was closing the cover "gently" because I was babying the new tonneau.
After I treated it like a truck and closed it firmly, the issue was resolved. Never opened again after that.
