2022 WINNEBAGO EKKO Engine Problems

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...

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...

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 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.
