NHTSA Complaint #11520227 — 2018 RAM PROMASTER

As of approximately around the 15th of April 2023, we realized suddenly that our lithium battery in our 2019 Winnebago Travato was not being replaced with charging from our Volta alternator from driving or from our solar as it has always done. The KISAE DC to DC charger and the Volta system show an error message that they were/are ‘overheated’. Testing of the DC to DC charger shows that it’s receiving far over the correct voltage. Upon diagnostics at a RV dealership they found the alternator is being overcharged. The alternator must be replaced before it can be determined why the alternator is overcharging (since obviously safeguards are meant to be in place to prevent this). We discovered through online research of the NHTSA Recall ID Number 21V793 on Boldt 2021-22 and Travato 2019-22 with Volta Power Systems; Manufacturer; Winnebago Industries, Inc. Subject; Wire Harness Built Incorrectly; loss of over-current protection can cause the wires to overheat, increasing the risk of a fire. There was also another subsequent recall for Winnebago Travato 2021, Winnebago Boldt 2021, and Storyteller Overland Vans 2021 of the seemingly same exact issue again, “In the case that power connections are not properly seated severe voltage spike by intermittent connections could damage the filtering diode in the the alternator control harness (10001447) resulting in the possibility of a shorted wire, on the same circuit the order of the fuse and diode were reversed. In the case that the diode is broken in a closed condition, the sense wire could be shorted to ground resulting in an overheated wire or broken wire. The identified cause of the diode failure was excessive overvoltage spikes. When the diode failed, it failed closed and with the diode and fuse being reversed the wire continued to heat up instead of breaking the fuse. With evidence from our van I believe in a strong probability the scope of the recall should be widened to include more units, such as ours. We are proof
