Recalls, owner-reported complaints, investigations and safety data

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.
0
Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Latest Jul 29, 2020
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

Jul 29, 2020
463 units potentially affected
The defect: 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.
The 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.
The 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.

Jun 9, 2020
71 units potentially affected
The defect: 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.
The risk: If the window glass detaches while the vehicle is moving it could become a projectile, increasing the risk of a crash.
The 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.

566 units potentially affected
The 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.
The risk: If the brake fluid leaks, this may extend the braking distance, increasing the risk of a crash.
The 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.

BACK OVER PREVENTION

On certain Mercedes-Benz Sprinter vans, the MBUX multimedia system software might not meet specifications. Under very specific conditions, the MBUX multimedia system might not start and the display might remain black, or could reboot unintentionally after 50 seconds of initial startup. Accordingly, the rearview camera image might not be displayed or the display might be interrupted, which could increase a risk of a crash or injury. This affects the following Thor Motor Coach products: model year 2020 Citation, Siesta, & Synergy; 2020-2022 Delano & Tiburon; 2021-2022 Sanctuary & Tranquility motorhomes.

SERVICE BRAKES

MBAG has determined that on certain model year 2019-2020 Sprinter vehicles, the retaining washer on the bolt that connects the brake pedal to its bearing block could come loose. If the retaining washer were to come loose, over time it could detach from the bolt, and in the worst case and with ongoing use of the brake pedal, the bolt might separate from the bearing block on one side. If this were to occur, the brake lamp switch could become continuously activated even when the brake pedal is not pressed. If the brake lamps are continuously illuminated, it would not be possible for following traffic to determine the braking intention of the vehicle, which could increase the risk of a crash. This affects the following Thor Motor Coach products: model year 2020-2021 Citation, Compass, Daybreak, Delano, Four Winds, Freedom Elite, Gemini, Quantum, Siesta, Synergy, and Tiburon motorhomes.
