2023 WINNEBAGO EKKO Electrical System Problems

Balmar alternator began smoking and emitting a burning smell, also began discharging the house batteries. This condition caused us to be disabled along the roadway and entailed crawling under the vehicle to disconnect the wiring from the alternator. Unable to get immediately repaired as no Balmar replacement parts were available from Winnebago. Repairs completed December 2024 by dealer. Additional Service Campaign 75-09 on Balmar alternators May 20, 2025 to cut charging rate by approximately 50% to prevent overloading. This service also completed by dealer August 18, 2025

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.

The winnebago EKKO has a secondardy alternator (Balmer brand) that charges the coach Lithium battery. There is an existing Winnebago recall regarding this component , Winnebago #174 and I originally had the Balmer alternator fail in summer 2023 and it was repaired by Winnebago under the #174 recall. The Balmer alternator has now failed again as of January 2025, and is appearing to heat beyond normal. The symptom of this failure, is lack of charging of the battery during engine operation, as well as tripping of the main coach power breaker. I have disconnected the alternator to prevent any safety issues such as over heating. Others will same vehicle have reported safety issues such as overheating and potential fire. I have reported this to Winnebago customer service. But I have not had the vehicle yet inspected by Winnebago or other service center, but have an appointment with Winnebago factory service...

Since I have picked up my Winnebago Ekko (motorhome) on [XXX] from Lichtsinn RV in Forest City, Iowa (1 mile from the factory) it has had numerous electrical fires in the kitchen and also has had no fewer than the 4 separate strains of mold growing throughout the motorhome as evidenced by the results of the mold test I did last spring. Although I have notified Winnebago Customer Care, Winnebago's CEO (Michael Happe), Lichtsinn RV and the Iowa Attorney General's office (where I have an open investigation for also being forced to pay an additional $25,000+ at the closing table or walk away after two years of waiting when I was told it would be six months) last spring when I emailed them the results, there has been NO response yet from anyone at Winnebago or Lichtsinn RV regarding these issues. I have made a video on YouTube showing the...

Second Balmar alternator failure - this failure occurred after the recall was performed for this same issue by Winnebago at their factory. Originally purchased Sept 2022, first Balmar alternator replaced Sept 2023 along with the recall 174 being accomplished at the factory. Second failure occurred Dec 2024 after 17k miles since the recall was accomplished. This appears to be a continuing issue as many other Ekko owners have reported multiple Balmar alternator failures. Symptoms prior to the failure was erratic charging and then subsequent tripping of the 250 Amp breaker. I was unable to restore charging and disconnected the alternator at the controller to prevent any additional issues.

The contact owns a 2023 Winnebago Ekko RV built on a 2022 Ford Transit Chassis. The contact stated that the RV blind spot monitoring system had become inoperable. The contact stated that the red light on the passenger's side and the driver's side of the windshield had failed to illuminate, and the alarm failed to sound while there was another vehicle in the blind spot. The RV was taken to an RV dealer, where the blind spot monitoring system was replaced; however, the failure recurred approximately 3 months later. The RV was taken to a second dealer, Lichtsinn RV (505 IA-9 East, Forest City, IA 50436), where it was diagnosed that the exterior modules of the blind spot monitoring system were susceptible to water damage, which caused the interior of the modules to become wet and to fail. The dealer determined that the modules needed to be replaced. The RV...

Balmar whine has indicate to be the first step before fire starting in the engine compartment

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,...

After completion of NHTSA Campaign Number 23V-234, the Balmar alternator charging system on my EKKO has twice shutdown and gone into a locked state which also trips the 250A house breaker in the RV. This state disables all charging while the engine is running and also disables the house 12V system due to the breaker trip. The locked state is supposedly triggered by an alternator over temperature condition. The NHSTA campaign previously replaced this entire Balmar charging system and its wiring, however, there are still clearly issues with the post-recall system as it fails and shuts down. The safety issue here is that the Balmar system over temperature condition can lead to a fire. Winnebago has not been helpful and refers me to Balmar. Balmar is entirely non-responsive and does not answer any calls or emails via their support mechanisms.

The Winnebago installed under hood generator (Balmar brand) produced a burnt, smokey smell immediately upon starting the engine on September 22nd. The previously 3 days when the vehicle was started and driven a whining type notice was coming from the generator. This was the first time any noise from the Balmar generator was given... 18,000 miles had been put on the vehicle during the last 11 months without issues. Since this is a well known issue with the Winnebago Ekkos I knew to pull the 4 pin connection to the house battery system to prevent any fires or other issues. With the Balmar being disconnected from the battery system there is no noise or burnt smell coming from the Balmar generator. And vehicle could be driven. As mentioned, Winnebago is well aware of this issue and said they had fixed the problem when I purchased this camper RV in 2023....

Have completed work for: NHTSA SAFETY RECALL 23V-234, had failure AFTER recall. Vehicle has 16250 miles on it. Balmer alternator failed, heavy smoke, very bad smell, no fire visible. disconnected 4pin control wire Reported to Balmer and Winnebago.

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.

The Balmar alternator gets very hot and emits very loud high-pitched whine. Others who have reported this heat/sound without further action have reported the alternator has caught on fire.
