Yep, have an XR3037HC that had much the same issue from the factory.
Mine had a ground short at the cruise control.
Then another ground short somewhere else. I can't recall.
Chalk it up to new vehicle hiccups and go on.
Overall build quality is great and saved thousands compared to orange, green of NH blue.
Spent the balance in quality attachments and a third function on the joy stick.
Great job, LS!!
