The Towed Battery Charger Plus (TBC+) manufactured by RVIBrake.com (DBA: Danco) of Castle Rock, CO 80109, was installed on our Honda Fit, prior to a vacation in May 2021. While heading back to our home in Florida on July 11 2021, on Interstate 84 near Matamoras, PA, we started smelling burnt plastic. We pulled off the highway and noticed the burnt smell coming from under our hood. Upon opening the hood we could see the TBC+ smoldering. The result of this aftermarket component (TBC+) failing caused an under hood fire, which melted plastic components on the Honda Fit. This TBC+ also shorted, resulting in sending excess voltage and current to the electrical components on the Honda fit. This resulted in our alternator failing. As it is a fire hazard, I would like all TBC+ modules manufactured by RVIBrake.com to be recalled and all owners of this module get compensated for any expenses resulting from this device.
