2025 WINNEBAGO EKKO Electrical System Problems

Brand new 2025 Winnebago Ekko after only 6,000 miles... The Winnebago installed Balmar Alternator Started Burning & Smoking rendering the vehicle unsafe to drive.

On [XXX] while driving my 2025 Winnebago Ekko 23B at elevations between 5,000 and 6,000 feet, the vehicle repeatedly lost engine power and stalled under specific conditions, creating a significant safety hazard. The issue occurred when the house batteries were below 100% charge, the engine was at idle or low RPM (below 1,250), and the secondary alternator began charging the Lithionics battery system, causing RPMs to drop below 500, complete loss of propulsion (unable to move forward or reverse), and occasional activation of the check engine light with codes P0506, P3002E6, and P30059B. This happened four times, including twice when attempting to pull out from stops, which could have resulted in a collision if traffic had been present—imagine suddenly stalling in an intersection with family aboard. The problem resolved at lower elevations (below 2,000 feet) or when maintaining higher RPMs before charging initiated, but it was reproducible every time the...

Short Answer: Winnebago has not conformed to its obligations with respect to NHTSA Safety Recall # 24V-541 (Winnebago # 186). Our 2025 EKKO 23B was within the scope of NHTSA Safety Recall # 24V-541 (Winnebago # 186). Winnebago did not offer to us a remedy -- other than to disable for an indeterminate length of time the solar charging system to which the recall applies -- within a reasonable time of their discovery and announcement of the recall. Accordingly, we paid for a remedial installation that, in the opinion of the expert in solar charging systems who made the installation, rendered the previously unsafe system safe for use. When Winnebago finally published its proposed remedy, we timely exercised our option to seek reimbursement for the work we'd already commissioned to have the problem cured. Winnebago assigned "case number" 00* * * * 27 to our request. On November 21, 2024,...

A fuse between the solar panels and solar controller melted and caused it to flame up. The incident could have caused a major fire. The problem has occurred on other units with various other owners. No. Winnebago is aware of the incident but we have not heard anything from them. There were no indications that this was going to happen.

The solar panels on this RV are wired to the solar controller through a 30amp fuse. The fuse holder gets extremely hot during peak solar charging in the afternoon. In order to inspect the 30amp fuse I removed it and it appears to be partially burnt. I am concerned about the heat that is generated at this fuse and fuse holder and I am aware of other Winnebago Ekkos reporting similar findings. I will leave the fuse removed until further notice from Winnebago.

the fuse behind the Zamp solar controller on our 25 Ekko 23B melted and caused a fire inside the cabinet above the fridge. This resulted in significant damage to the solar controller, wires and the cabinet itself. Not to mention the strong and persistent smoke smell inside the vehicle.

The 30amp electrical fuse connecting the solar panels to the Zamp 40amp controller melted. Lichtsinn Motors, the dealer, was notified and sent pictures of melted fuse. CoachNet technical support was also called, spoke with technician and pictures of melted fuse sent. Detailed message left with Winnebago. Customer service agent said Sept 13th was the notification date for the recall however they have no solution yet.
