My display on my himiway with 250 miles went to error 30 and turns off the disp[lay. No power to teh rear motor. I have replaced the controller and the wiring harness as sent from Himiway without any success. Dealing with that company is the pits. No way to talk with a tech on the phone and the customer is left to diagnose his own problem even though its under warranty. Worse purchasing decision of my life. Anyone else have this problem?
