NHTSA Complaint #11616992 — 2022 WINNEBAGO EKKO

Winnebago adds a 2nd alternator to the engine for charging the coach/house Lithionics batteries. This 2nd alternator is a Balmer brand. The Balmer alternator suddenly developed a high pitched whine. Once whining it ceased to charge the batteries. The Balmer regulator begins to smoke quickly once the alternator is whining. We’ve been told to disconnect the regulator quickly or a fire can happen (we’ve been told others have had fires). This is our 2nd Balmer alternator failure. The first failed alternator was replaced at the factory end of July 2024 (apx 60 days ago). Changing the alternator is not addressing the root cause and the danger of a fire. Winnebago and Balmer have been aware of this risk for months and have not been able to identify the root cause.
