2020 THOR MOTOR COACH DAYBREAK

SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:HOSES, LINES/PIPING, AND FITTINGS

Thor Motor Coach (TMC) is recalling certain 2020 Daybreak, Four Winds, Delano, Gemini, Quantum, Tiburon, Chateau Citation, Compass, Chateau, Siesta, Freedom Elite, and Synergy motorhomes built on Mercedes Benz Sprinter chassis [platform 907 (VS30)]. The rear part of the fender liner on the front axle may contact and chafe the brake hose, possibly resulting in a loss of brake fluid.

Risk: If the brake fluid leaks, this may extend the braking distance, increasing the risk of a crash.

POWER TRAIN:AUTOMATIC TRANSMISSION

Thor Motor Coach (TMC) is recalling certain 2020 Daybreak, Four Winds, Delano, Gemini, Quantum, Tiburon, Chateau Citation, Compass, Chateau, Siesta, Freedom Elite, and Synergy motorhomes built on Mercedes-Benz Sprinter chassis [platform 907 (VS30)] equipped with automatic transmissions. 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.

SEAT BELTS

Thor Motor Coach (TMC) is recalling certain 2020-2021 Daybreak 23DB, 2018-2021 Four Winds 23U, and 2018-2021 Chateau 23U motorhomes. Bolts of the wrong size were used to secure the barrel chair pedestals, allowing the pedestal to separate from the floor in the event of a crash. As such, these motorhomes fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 207, "Seating Systems" and number 210, "Seat Belt Assembly Anchorages."

Risk: If the pedestal were to separate from the floor during a crash, the seat belt anchorages may fail, increasing the risk of injury.

ELECTRICAL SYSTEM:WIRING

Thor Motor Coach (Thor) is recalling certain 2020-2021 Daybreak, Four Winds, Quantum, Delano, Tiburon, Chateau and Freedom Elite motorhomes and 2020 Gemini, Chateau Citation, Compass, Siesta, and Synergy motorhomes built on Sprinter Van chassis (platform 970 (VS30), equipped with swivel seats. The wiring harnesses for the front seats may have been routed incorrectly and could become jammed and damaged in the swivel seat frames.

Risk: If the wiring harness is damaged, the side air bag within the seat may deploy inadvertently or not deploy as designed in the event of a crash, increasing the risk of injury to vehicle occupants.
