The owner's manual does not correctly specify the certain conditions under which the automatic parking function (Auto-P) operates.
Risk: If a customer were to rely on the Auto-P function as described in the Operator's Manual, the possibility of a vehicle rollaway or unintended vehicle movement cannot be ruled out which could increase the risk of a crash.

The wiring harnesses for the front seats may have been routed incorrectly and could become jammed and damaged in the swivel seat frames.

The rear axle differential may have an insufficient amount of fluid, possibly resulting in a failure of the rear axle assembly and a driveshaft separation.
Risk: If the driveshaft separates, there may be a loss of drive, increasing the risk of crash. Additionally, if the parking brake is not applied, unintended vehicle movement can occur if the transmission is left in Park, increasing the risk of injury or crash.

Thor Motor Coach (TMC) is recalling certain 2020-2021 Quantum, Chateau and Four Winds, and 2020 Vegas and Axis motorhomes built on a Ford E-series chassis. A wire harness in the rear of the vehicle may contact the vehicle frame, resulting in damage to the circuits that support the fuel pump and the anti-lock braking system (ABS).
Risk: Damage to the fuel pump circuit in the wiring harness could result in an unexpected engine stall. Damage to the ABS wiring can lead to reduction of ABS functionality and a loss of roll stability control (RSC) functionality. These scenarios increase the risk of a crash.

2024 THOR MOTOR COACH QUANTUM
ID: 2099190UNKNOWN OR OTHER
Drove from Gibson Louisiana to Abita Springs Ocean Canyon RV park. Upon arrival we had a buzzer alert going off under dash, we then parked to RV. Tried to put jacks down, did not respond, tried 12v lights did not work, tried slides, again no response. We then plugged in and were able to get jacks and slides out, some lights worked. Still alarm under dash, checked 12 coach battery, almost dead. Called a mobile RV tech, 2 1/2 hours later, he found a ground bolt had come off with 3 grounding wires on it. Tech advised that bolt was only tacked on one side, my Warranty company said a original technician fault and not covered. Talked to Thor later, they advised that is how it is attached, advised warranty company and they still denied. Told Thor that was very poor workmanship for a company trying to improve their standing. This cost me $358.05 out of pocket and time from Rving.
