Had a issue with ours until I actually read how they are supposed to work. Just had to be patient and let them work. Turn the system on and wait until it cycles through all the lights flashing then hit auto. It levels the coach perfect everytime but can take a minute or two. Do the same thing and hit retract, that can also take 30 seconds to a minute. Found out it won't work properly unless both coach batteries are good and completely charged. It wouldn't work properly when we first got the coach so I installed a battery tender for all the batteries keeping it plugged in when not using the unit. Never had a leveler problem after that.
