NHTSA Complaint #11626480 — 2020 FORD TRANSIT

My Balmar 2nd alternator on my Winnebago Ekko has just failed. This is a Winnebago installed electrical system component mounted in the Ford Transit chassis engine bay that provides electrical charging to the RV coach batteries. There was an initial NHTSA Safety Recall 23V-234 issued in 2023 after numerous Balmar units failed; in some cases the Balmar unit failure caused a fire in the engine bay. I had the Safety Recall work performed in July 2023 by authorized dealer Dennis Dillion RV in Boise Idaho per the attached invoice and the Balmar charging system had been working well until now. I am aware that there are ongoing reports by other Ekko owners of the Balmar alternator failures reoccurring after the Safety Recall work was performed, and in some cases even after Balmar 2nd alternators' were replaced, which suggests the initial solution provided by the Safety Recall was not sufficient to prevent a failure. Within minutes of starting to drive my RV today I noticed an unfamiliar whining sound from somewhere under the hood that I had not heard before and immediately checked my coach batteries while driving a short distance and went from the batteries discharging significantly to not charging at all. I opened the engine hood and had smoke visible and a strong burning smell coming from the passenger side of the engine bay where the Balmar unit is located. I was very concerned about the potential for an engine bay fire, but fortunately was very close to my home, so my RV is now parked in my driveway. See attached screenshots showing the initial voltage discharge while driving and then the batteries not getting any charge while under power. Also attached is the Recall 23V-234 repair instructions. I plan to unplug the Balmar alternator to prevent the potential for a fire while awaiting a response from Winnebago how to proceed. Despite the NHTSA Safety Recall having been performed, there are reports of alternator's failing and risk of vehicle fires remains.
