2023 Winnebago Ekko Problems

After starting the vehicle I noticed an unusual whine. After a few seconds of idling I noticed that it smelled like something was on fire. I turned off the vehicle and began looking for smoke. I did not find it. After a little research I discovered that it is a very well known failure that the Balmar alternator on Winnebago EKKOs fails catastrophically, sometimes catching on fire. I followed instructions to disable the Balmar. I let the vehicle cool completely. I restarted the vehicle and let it idle for a long while and the whine and the smell never returned. I used the Lithionics app to confirm that the batteries were not being charged while the engine was idling.

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.

Blind Spot Monitor System never worked from the time of purchase of this vehicle, and yes it’s available for inspection. Eventually took it to the Winnebago Factory Service Center in Forest City Iowa to be fixed in August 2023. It worked after that for about 200 miles or until the first rain and then it stopped working. I put on my turn signal to move to the left lane and there was a car in my blind spot. No warning from the BSM. Very dangerous. No warning at all. If you look at the Facebook group “Winnebago Owners And Wannabes” do a search on Blind Spot Monitor. You will find many with the same issue.

This motorhome is equipped with a Blind Spot Warning system. I've had the vehicle for one year. The system stopped working after 2 months and then was replaced on warranty. After 5 more months of use the system malfunctions again: it gives warnings and detects vehicles only on one (left) side of the vehicle.

Reference NHTSA Safety Recall 23V-234 Just experience failure of second Balmar alternator at about 26,000 miles. Replacement of first failure was done in conjunction of above referenced safefy recall. Work was performed in March of 2024. Subsequent to the above referenced recall Winnebago issued a Service Campaign (75-09) to derate (adjust/lower alternator output settings)in order to reduce the risk of overloading the alternator. The service campaign work was completed in June 2025. Numerous other Ekko owners have experience multiple Balmar alternator failures including some that have caught on fire. I was aware of the early warning signs of problems (high pitched whine that varies with RPM's and alternator output that drops to near zero) and proactively unplugged/disconnected the alternator before potentially serious consequences arose. My situation, and those of other Ekko owners clearly shows there is a design and/or quality issue that requires corrective action.

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.

Hankook Dynapro HT 205/75R16C We found out when we were having the oil changed. Both front tires have steel fibers showing on 14,882 miles. Lucky we weren't on the highway. I would never have guessed that 1.5 year old tires would be this worn. Properly inflated, by the way.

When at the Winnebago factory service center for other recalls and repairs, technicians found that the propane line going from the regulator at the tanks to the cooktop in the kitchen was worn and frayed, having rubbed against the rear tires for more than 15,000 miles. They said it was a safety hazard and had to replace the line and ensure it would no longer rub against the tires.

In August 2023 while driving at highway speed - without warning - a loud screeching suddenly began from the left front wheel of our 2023 Winnebago EKKO RV (built on a 2022 Ford Transit 3500 AWD chassis) - fearing a potential brake failure I took the vehicle to a mechanic who discovered a bolt from the brake heat shield had detached and was lodged between the brake caliper and rotor, the bolt had scored the rotor - the mechanic dislodged the bolt and stated he had to bend the heat shield slightly to prevent it rubbing. Approximately 2 weeks later the exact same scenario occurred with the right front wheel - this occurrence was verified & remedied by a Ford dealership. I saved this bolt as evidence. Both shops stated that this situation, if not corrected, could damage the front brakes.
