I have the Parksense system on my wife's JLU Sahara. I got her a spare tire cover and put it on this morning. We went out and when backing out of a parking space I noticed I was getting a warning on the right side of the alert. I also noticed that the backup guide lines were missing. After looking at the sensors and camera to make sure they weren't hit, I took the cover off. This fixed the alert but it took about 6 restarts and messing with the settings to get the lines back. Has anyone else had issues with a tire cover and if so what fixed it?
