Hi, we have a 2350 2019 and have had a variety of jack issues. There appears to be fluid leak from the reservoir cap periodically. I have had to replace a couple of the sensor and solenoids. Just recently I noticed 2 of the jacks not working and found crimpled wires on the harness which seems from the vehicle motion or bounce. I am hoping after cutting the wires, reconnecting, and securing the wires will resolve the issue. We don't have any service options in Maryland so continue trying to perform as much self repair as possible and phone support with Stuarts HMH service.
