NHTSA Complaint #11484164 — 2022 THOR MOTOR COACH SCOPE

This Thor Scope Class B RV is manufactured with two auxiliary batteries outside of and under the chassis to power electrical components in the RV. These batteries are not associated with the Promaster chassis/engine power and appear to be installed by the RV manufacturer. When the vehicle was delivered, there was a problem with battery charging in the auxiliary power system that was eventually traced to a cable that was supposed to connect the two auxiliary battery + terminals. That cable was connected two one battery but was left loose and disconnected in the other battery box. There is/was no overcurrent protection on this cable, and had the cable touched ground, it would have resulted in a direct short across the other battery, likely causing a fire. The lack of quality control at the manufacturer to deliver a vehicle with an imminent fire risk needs to be addressed.
