2022 WINNEBAGO EKKO Electrical System Problems

The Balmar alternator installed on our RV, which provides electrical power to charge the coach battery started a noticeable whine at idle, it stopped providing a charge to the coach battery, and upon further inspection, after opening the hood, we noticed a faint burning electrical smell. To confirm that the Balmar alternator was failing, I checked its electrical output to the battery, and it was not charging. I then proceeded to unplug the regulator for the alternator to see if the whine and smell were still present. They were not. Since the whine was not present with the Balmar alternator unplugged, the burning smell had dissipated, and no charge coming from the alternator when plugged in, I determined it was starting or already failed. Knowing that there have been multiple reports from other owners that their EKKO's caught fire or had severe smoke coming from the engine compartment, that was...

October 10, 2025. The vehicle is a 2022 Winnebago EKKO RV on a 2021 Ford Transit with 49,000 miles. The incident occurred after driving the vehicle for about 5 minutes with outside temperatures around 50 degrees Fahrenheit and noticed an unusual high pitch whine. When I opened the hood the Balmar MC-618 Alternator unit was extremely hot, smoking, and had 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 and the whining sound and burning smell immediately returned. 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. This recall was completed during the time...

This is to report a failure after NHTSA campaign number 23V234000 was addressed by Winnebago through their campaign number 174. I had the fix performed by Winnebago at their factory service center about 20k miles ago and the alternator failed again with the exact same symptoms. This is my 5th alternator failure in 60,000 miles and 3 years.

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,...

The Winnebago factory installed secondary alternator (manufactured by Balmar) responsible for charging the batteries in my motorhome started to whine and overheat. Luckily the week prior, I had read about another EKKO owner experiencing the same symptoms before it created enough smoke that caused the driver to immediately pull off the road and extinguish the engine bay with a fire extinguisher. In an effort to avoid that, I disconnected the Balmer until it was able to be replaced. This original problem was supposed to be addressed in recall 174. Over a year later the recall supposedly addressed the issues by moving the regulator out of the engine bay, replacing the Balmer and a major reworking of the electrical system. After multiple components failed during the recall repair, my EKKO took over 6 weeks to get a working solution at a Winnebago dealership. That was a year ago. 10 days ago...

8 October 2024 Winnebago Ekko owners are looking for clarification on NHTSA recall 23V-234. The number of owners who have experienced Balmar alternator failure after the recall work is growing. We are among them. A post-recall fire has also been reported (October 6 2024 in Washington State) Manufacturer's response to this situation has been, so far: 1) Replace the alternator at no charge 2) Replace the alternator at no charge, with a verbal warning that no more alternators will be furnished free of charge, directing owners to instead contact the component manufacturer (Balmar) for additional relief. Both are unacceptable. The recall was ordered to prevent 1) alternator failure and 2) a potential fire. The recall does neither and the RV manufacturer must be held accountable. Our 23V-234 recall work was completed in February 2024. The alternator failed in June 2024. Yesterday, October 7, the dealer installed a manufacturer-authorized replacement alternator...

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.

Winnebago recall 174 (NHTSA campaign 23V234000) regarding improper electrical wiring design and installation by Winnebago was recently completed on my RV. After completion of this recall I experienced another electrical fire in the engine compartment (my alternator had previously caught fire due to wiring and design defects noted in Winnebago recall 174). After extinguishing the fire I observed the Winnebago recall 174 remedy had been completed in such a way that an engine compartment wiring harness was under tension and in contact with the threads of a bolt on the backside of the new alternator installed as part of the Winnebago recall 174 remedy. This seems to have resulted in electrical anomalies and eventual ignition of the wiring harness. There were repeated brief intermittent brake and rear hatch warnings shortly before the fire (there is no rear hatch). The windshield washer system failed after uncommanded operation of the windshield wipers....

Balmar alternator or regulator fails to work as designed. No charging of batteries when idling or driving. This is a Safety Issue because fires have been reported as a result of these electrical system failures. Lithionics (battery) app confirms no charge reaching the batteries, see attached screenshots. Potential Risk of Fire when not working properly as evidenced by others with Balmar failures as reported to NHTSA. This is the 3rd failure we have encountered: 1st failure confirmed by Winnebago, and was replaced with like parts. 2nd failure occurred just prior to the 2023 recall, and was addressed by Winnebago Factory Service during recall by replacing parts again. 3rd failure occurred today. The current failure happened when the unit (2022 Winnebago EKKO) was parked in our driveway, not while travelling. Upon starting the vehicle, the alternator emitted a loud whining sound and subsequently provided no charging to the batteries. We are...

The prior recall #174 was completed at the Winnebago Factory Service Center in September of 2023. The replacement alternator failed and has now been replaced as a warranty item but the Factory Service Center. This is the 3rd Balmar alternator for this unit. The first replacement was approximately in October of 2022, then the recall was performed in September of 2023 which included replacement of the Balmar alternator, now that has malfunctioned once again necessitating replacement. All seem fail in one year increments.

40 amp fuse for Solar charger burned. Replaced fuse and fuse holder became too hot to hold with bare hand but didn't blow the fuse. This type of heat causes a risk of fire inside the motorhome. Currently unable to use solar, a significant element of our ability to enjoy the rig.

Winnebago serial number: [XXX] This vehicle has already had the recall work done as described in NHTSA Campaign Number 23V-234. This work was performed at NIRVC in Las Vegas on or around February 7, 2024. Their work was excellent, however the Balmar alternator has once again failed. The prior electrical system recall was completed at the factory service center in Forest City Iowa. Additional service was performed before the recalls were issued at Colonial Airstream (selling dealer) in New Jersey and at Roam Rig in Connecticut. Please pressure the manufacturer to revise the recall and fix what has been a never-ending headache for almost all owners, since purchase. Thank you.

Selling dealer preformed NHTSA #24V942000 Winnebago Ekko Recall # 165 in January 2022. The repair procedure held up delivery of the vehicle for months. A serious defect in their workmanship that could compromise the intended goal of correcting a potential hazard to nearby electrical components was later identified by me & reported to the dealer, and manufacturer. The dealers response was to deny that they performed the recall and reject that the area of concern, a sink drain line connection was part of the recall. I made it glaringly apparent that they were wrong in both regards & the dealer stopped responding to my request to correct. Reference WGO- Instructions To Perform Recall Campaign 165, pg 18 steps 74-77. I reported it to the manufacturer & in October 2023, after traveling 3400 miles round trip to the Winnebago factory service center, the defect was corrected. The dealer also failed to...

After numerous prior repairs & recalls related to the Balmar Aux. charging system installed in our Ekko model RV by Winnebago, we again returned to the factory service center for the second time this year to have the latest recall, NHTSA 23V-234 WGO Recall 174 completed. After the third day in the shop for the Balmar recall & other repairs the vehicle was returned to me. The tech advised me that 1 lithium battery from the dual set had to be replaced. After a quick visual inspection in the tech’s presence I pointed out several workmanship issues that required the coach to go back into the shop to correct before shop closing. That evening I drove the coach onto blocking to visually inspect their unseen work. I found several issues including a loose terminal connection of a high current 3/0 B+ battery cable at the newly installed alternator and an...

The solar panels ceased to charge the batteries. I found a 40A Fuse holder behind the solar controller in the coach, that had melted and looked like it could have caught on fire.

Balmar Regulator creating sparks under hood eventually blowing a fuse. Shows signs of a shorted wire somewhere in the vehicle.

This is allegedly related to the Balmar relay system installed by Winnebago in the Ford Transit van.It is currently at the dealer, Colonial Winnebago, in Millstone Twp., NJ. Dealer can be contacted for inspection. We began traveling at a 25 mph speed for about 2 miles when smoke began to flow from under the hood. We pulled over to inspect; 911 was called. Smoke and flames under the hood were visible and continued until the fire truck came and extinguished the fire. Our safety and the safety of others was put at risk as the unit did not display any warning signs on the dashboard, there was a fire and smoke under the hood, we were in a public parking lot, and the unit carries 2 20 lb. propane tanks. Problem was diagnosed by our local Ford dealer, who stated that this is a Winnebago issue, as this was a...

The Balmar charge controller for the coach lithium batteries failed. The controller is rated for temperatures up to 90 C (194 F). Based on Ekko forum discussions I suspected the controller, which is located in close proximity to the passenger side turbocharger was overheating. I fashioned an improvised heat shield between the turbocharger and controller and after driving in 74 F ambient conditions measured temperatures of 285 F on the heat shield and 185 F at the controller surface. I also added heat shielding to the controller wiring, which is also very close to the turbocharger. Clearly without owner-added heat shielding, (and even with during higher than 74 F ambient temperatures) the controller is far exceeding it's allowable temperature maximum.

The auxillary alternator caught on fire. The dealer retained the part when replaced. Fire risk to ourselves and entire rig. Yes, the problem was confirmed by a dealer. The Yuma, Az fire department responded and wrote a report. There were no warning lamps, messages or other symptoms,

The secondary alternator caught on fire while traveling and damaged the Ford tensioner that supplies AC compressor power

Wiring harness and a fuse on the harness for the auxiliary Balmar alternator installed by Winnebago partially melted due to proximity to turbocharger. Very concerning due to other owners reporting Balmar alternator fires and alternator regulator failures.

The entire shower water after use was draining directly onto the inverter creating a fire hazard.
