2022 Vanleigh Vilano

The contact owns a 2022 Vanleigh Vilano. The contact stated that the cabinets had separated from the wall and struck the rim, and the refrigerator separated and fell into the aisle while driving. The contact stated that the refrigerator power inverter had failed and almost caught on fire. The contact stated that the shelf separated and fractured the curtain valance. While in the process of replacing the water heater, the contact noticed that the frame was fractured and appeared smashed in. The contact stated that the RV was defective from the factory. The RV was taken to the dealer, to whom the contact provided photos of the failures. The dealer informed the contact that the failure would be reported to the manufacturer. The contact stated that the RV remained at the dealer unrepaired for a year and nine months. The manufacturer picked up the RV and performed unrelated minors repairs, and then the manufacturer returned the RV to the dealer with an unrepaired frame and other major reported failures. The RV was not repaired. The failure mileage was approximately 400. The VIN was not available.

Started getting messages that trailer brake gain was not recalled on the dash display. The NAV display continued to show no connection errors. The problem escalated to a turn signal failure. The left turn signal flashed and sounded an alarm when changing lanes. The nav display did indicate a turn signal connection error. I tried moving the 7 pin trailer cable to another connector and the brake gain warnings continued. My tow vehicle is a GMC Sierra 3500HD Denali. I remembered seeing this issue on an RV forum and the fix is spraying contact cleaner into the 7 pin plug. The contact cleaner did stop the warning messages. The Denali is equipped with a trailer package. The package includes a lamp test. The lamp test cycles the trailer brake and turn signals. We always perform the lamp test before traveling with the trailer and it has always passed. The turn signal failure did not cause an accident. My concern is that the cable and plug is a component common to other RV manufacturers. An electrical failure of the brakes or turn signals could result in a serious accident. Does the 7 pin plug require a design change to eliminate corrosion issues?
