Recall history
5 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
20V308000 · Equipment:Other:Owners/Service/Other Manual | Power Train:Automatic Transmission
Reported: 2020-05-27 (May 27, 2020) · Model years: 2020
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.
Consequence: 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.
Remedy: 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.
NHTSA campaign record ↗20V312000 · Structure:Frame And Members:Underbody Shields | Service Brakes, Hydraulic:Foundation Components:Hoses, Lines/Piping, And Fittings
Reported: 2020-05-28 (May 28, 2020) · Model years: 2020
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.
Consequence: If the brake fluid leaks, this may extend the braking distance, increasing the risk of a crash.
Remedy: 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.
NHTSA campaign record ↗20V339000 · Visibility:Glass, Side/Rear
Reported: 2020-06-09 (June 9, 2020) · Model years: 2020
Thor Motor Coach (TMC) is recalling certain 2020-2021 ACE, 2021 Four Winds and 2020 Gemini, Axis, Compass, Delano, Windsport, Hurricane, Outlaw, and Vegas motorhomes. The adhesive bond between the glass and the metal hinge frame of the frameless windows may fail which would then allow the glass to detach and fall out.
Consequence: If the window glass detaches while the vehicle is moving it could become a projectile, increasing the risk of a crash.
Remedy: TMC will notify owners, and dealers will inspect the frameless windows for proper adhesive bond strength, replacing the windows as necessary, free of charge. The recall began July 10, 2020. Owners may contact TMC customer service at 1-877-855-2867. TMC's number for this recall is RC000192.
NHTSA campaign record ↗20V444000 · Seats | Air Bags | Electrical System:Wiring
Reported: 2020-07-29 (July 29, 2020) · Model years: 2020, 2021
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.
Consequence: 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.
Remedy: Thor will notify owners, and Mercedes-Benz dealers will inspect the wire harness routing for both front seats and will repair the wiring and add clips or cable ties as needed, free of charge. This recall began August 13, 2020. Owners may contact Thor customer service at 1-877-855-2867 Mercedes-Benz customer service at 1-877-762-8267. Thor's number for this recall is RC000200.
NHTSA campaign record ↗22V300000 · Equipment:Recreational Vehicle/Trailer:Lpg Systems:Lines And Fittings
Reported: 2022-05-05 (May 5, 2022) · Model years: 2022
Thor Motor Coach (TMC) is recalling certain 2022 Scope, Tellaro, Sanctuary, Delano, Sequence, Tranquility, Rize, Synergy, Quantum, Magnitude, Geneva, Compass, Chateau, Four Winds, and 2022-2023 Tiburon, and Gemini vehicles. The quick disconnect fittings in the LP gas system may be cracked, causing a gas leak.
Consequence: A gas leak in the presence of an ignition source can increase the risk of a fire.
Remedy: Dealers will replace the quick disconnect fittings, free of charge. Owner notification letters were mailed June 27, 2022. Owners may contact TMC customer service at 1-877-855-2867.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
2021: 2 complaints · 2022: 1 complaints
| Model year | Through age 0 | Through age 1 | Through age 2 |
