Defect: 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.
Fix: TMC will notify owners, and an authorized Mercedes-Benz dealer will inspect the brake hoses for chafing and replacement if necessary. The fender liner will also be altered to permit more clearance. All repairs will be performed free of charge. This recall began June 25, 2020. Owners may contact TMC customer service at 1-877-855-2867. TMC's number for this recall is RC000191.
Equipment:other:owners/Service/Other Manual 2020-05-27 · campaign 20V308000 · 566 vehicles
Defect: 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.
Fix: TMC will notify owners, and a Mercedes Benz dealer will supplement the Operator's Manual with a correct description of the Auto-P function equipped in the vehicle. This recall began June 25, 2020. Owners may contact TMC customer service at 1-877-855-2867. TMC's number for this recall is RC000190.
