2023 Winnebago Ekko

We had reported on Sat, 3/21/26 to Winnebago that we noticed our Balmar alternator had stopped charging the battery the night before on Fri, 3/20/26 during a 2.5 hour trip to Sebastapol, CA. We drove to Santa Clara, recharged batteries with shore power and then drove to Santa Cruz, CA. This morning on Sun 3/22/26, our 2nd Balmar Alternator installed by NIRVC/Las Vegas in Mar-April 2024 under the 174 Recall caught on fire. Fortunately, we were idling in a parking lot before getting on the freeway, and could hear the whining noise, smell the burning alternator, and see the smoke coming out of the engine before the fire grew too large. We were able to extinguish the fire and keep the damage limited to the Balmar alternator. Had we gotten out onto Highway 17, ours and others lives could have been severely impacted, as we likely would not have noticed nor been able to deal with the fire as quickly. We have unplugged the 4-pin wire plug from the Balmar regulator. Once we restarted the engine, a piece of plastic came flying out, and then everything started spinning freely. We were able to drive home. We have reported the fire to Winnebago and are awaiting communication as to next steps. We have video footage of the fire and vehicle is available for inspection.

We believe our Balmar (the second alternator that powers our Lithium batteries) failed and then created enough heat to either have a small fire or produce copious amounts of toxic smoke. This is a known problem with the Winnebago EKKOs. There has been one round of recalls for the Balmar re-wiring which we had done at the Winnebago Factory Center in Forest City, IA on November 21, 2023. We were in the parking lot at Whole Foods in Jackson, Wyoming when this happened. We opened the hood when we smelled the plastic burning smell and smoke was pouring out. People were gathering and telling us to call 911 to get the fire department out. We decided to discharge the fire extinguishers provided with our EKKO (a Kidde ABC model). If the whole thing caught fire, obviously other people and cars parked next to us would have been in danger. Yesterday, we heard a new “whine” coming from our engine and noticed that our app that measures the power coming into the lithium batteries was fluctuating way more than usual and so we suspected the system was starting to fail. We had no idea it would fail so quickly and so dangerously.

Last August 2023 we had Recall 174 completed at Winnebago’s factory service center. This was for the Balmar 2nd alternator, Regulator, and wiring harness. This morning around 6:45am upon starting the vehicle I smelled smoke. Since this is common when the alternator fails I checked our lithionics battery app to discovery we were not inputting any amperage to our house batteries from the 2nd alternator. It had burned up and failed once again (had failed last year, recall was done to fix it, and has worked since August 2023). We are not the first owners who have had the recall done and have the system fail again.
