NHTSA Complaint #11630850 — 2022 WINNEBAGO EKKO

The vehicle is a 2021 Ford Transit with a 2022 Winnebago Ekko RV. The incident occurred when I started the engine and noticed an unusual high pitch whine. When I opened the hood the Balmar unit was extremely hot with a strong burning smell. Since the Ekko models have had numerous reports of secondary alternator / Balmar malfunctions I knew enough to disable the alternator by unplugging the 4 pin connector on the Balmar 618 regulator before traveling any further. The following morning I plugged the Balmar unit back in place to see if the high pitch sound reoccurred. The sound immediately returned and I used my infrared thermometer which read 438 degrees Fahrenheit on the Balmar alternator. The Lithionics battery app indicated the batteries were 90 percent full but would no longer charge, leaving me only shore power to recharge the batteries. There is a NHTSA Safety Recall 23V-234, Campaign # 174 Ekko 12V Charging System, sent out by Winnebago for this very safety issue due to fires. We had this recall completed at the Forest City Iowa Winnebago factory in April of 2024. There have been numerous failures on Balmar units that have had the campaign #174 recall completed, including ones performed at the factory. The Winnebago fix is obviously not working and is still an extreme fire issue.
