Recalls, owner-reported complaints, investigations and safety data

Data refreshed

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.

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.

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.

The defect: Thor Motor Coach (TMC) is recalling certain 2016-2018 Thor Gemini and Compass recreational vehicles built on a Ford chassis and equipped with a trailer tow module. Water can enter the tow modules and corrode the wiring causing issues such as rapidly flashing turn signals, loss of instrument panel display, an electrical short and possibly the deployment of seatbelt pretensioner.
The risk: An electrical short can increase the risk of a fire. Turn signal, instrument cluster or seatbelt pretensioner problems can increase the risk of a crash.
The remedy: Ford has notified owners, and Ford dealers will add a drainage hole in the driver's door stepwell and incorporate a fuse into the vehicle's wiring harness, free of charge.

110,400 units potentially affected
The defect: Thor Motor Coach (Thor) is recalling various 2003-2018 recreational vehicles, equipped with Kidde Plastic-Handle or Push Button 'Pindicator' Fire Extinguishers. See a list of the affected trailer models at: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17V758-5764.pdf. These extinguishers may become clogged, preventing the extinguisher from discharging as expected or excessive force may be needed to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable. For a full list of the affected fire extinguisher models visit: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17E062-5427.pdf
The risk: In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.
The remedy: Thor will notify owners, instructing them to contact Kidde for a replacement fire extinguisher, free of charge. The recall began on January 15, 2018. Owners may contact Thor customer service at 1-877-500-1020, or Kidde customer service toll-free at 1-855-262-3540, or online at www.kidde.com and click on "Product Safety Recall" for more information.

There is a recall for my vehicle it is notice # 2021070007 despite your website stating there is none. My problem with your recall is that it only applies to the rear wheel sensors on the Mercedes sprinter chassis. I've had both front and rear wheel sensor failures on my sprinter both failures coming with less 5000 miles on my sprinter which the Mercedes dealership refused to repair. I don't why NHTSA would limit the recall to just the rear sensors when the front sensors are exactly the same as the rear sensors and are failing also. These are dangerous failures which disable the safety systems on the vehicles.

THE REAR SPEED SENSOR ON MY 2018 THOR GEMINI RV WITH THE MERCEDES BENZ 3500 SPRINTER CHASSIS WENT BAD KNOCKING OUT MY ABS, STABILITY CONTROL AND CRUISE CONTROL ON A LONG TRIP. I WAS ON THE HIGHWAY DOING A STEADY 60-65 MPH. MY SPRINTER ONLY HAS 8,000 MILES ON IT. I'VE READ THIS IS A RECURRING PROBLEM ON THESE VEHICLES SO I THOUGHT I WOULD REPORT IT.

ELECTRICAL SYSTEM

us. On certain model year 2012– 2018 5-ton Sprinter vehicles that were upfitted into campers or recreational vehicles (“RVs”), one or more of the rear-wheel speed sensors may experience an electrical failure, which potentially could lead to a disablement of the Electronic Stability Control (“ESP”) control unit functions. If ESP control unit functions are disabled, vehicle driving stability may be impacted under certain driving conditions, increasing the risk of a crash. This affects the following Thor Motor Coach products: model year 2013-2020 Chateau Citation & Four Winds Siesta, 2017-2019 Compass, 2017-2020 Four Winds, Gemini, Quantum, Chateau, & Synergy, and 2018-2020 Freedom Elite motorhomes

STEERING

It has been determined that on certain Mercedes-Benz Sprinter vehicles, the hydraulic power steering return line hoses might detach at their connection points under certain operating conditions, which could cause hydraulic fluid to leak, resulting in the loss of power steering assist. If the hydraulic power steering hose detaches, the driver will still have manual steering functionality, but increased steering effort will be needed, particularly at low speeds. Sudden loss of power steering assist as well as the loss of hydraulic steering fluid to the road surface may increase the risk of a crash. This affects the following Thor Motor Coach products: 2017-2020 Chateau, Chateau Citation, Four Winds, Gemini, Quantum, Siesta, & Synergy; 2018-2019 Compass; 2018-2020 Freedom Elite; 2021 Sanctuary & Tranquility
