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.

My wife and I were driving Westbound on [XXX] in Washington state just East of Seattle when the driver side slide out went out on its own while my wife was sleeping on the couch. After taking it to the center it was purchased at they told me it was a failure of the safety retainers on the locking dogs that keep the unit secure when retracted. The manufacturer denied to repair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Filed Jun 24, 2021

When driving with cruise control on and encounter a slight side wind or even a grade change in road surface where the coach is not perfectly level the cruise will quit and hill decent light comes on, will not rest until it is shut off for 10 min or so. It is a issue with steering angle sensor, I can be driving perfectly straight but if the steering wheel is turned off center for more than a half mile or so even though going straight , the cruise will quit. it can happen multiple times in a 300 mile trip, may not even work for the whole trip. or on a nice day straight road no wind it will be just fine. it is a correlation of steering angle to wheel turn angle, needs more range/allowance.

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.

WHEELS

According to the tire manufacturer, Continental Tire the Americas (CTA), the affected tires may have an overcure condition and CTA has initiated a safety recall for these tires. According to CTA, overcured tires may experience a carcass break in the sidewall with sudden air loss or could develop a belt edge separation which could lead to partial or full tread/belt loss. These conditions may increase the risk of a crash. This affects the following Thor Motor Coach products: model year 2019 Quantum & Freedom Elite, 2019/2021 Daybreak & Four Winds, and 2019-2021 Chateau motorhomes.

ENGINE AND ENGINE COOLING

On your vehicle, it may be possible that the engine cover insulation does not fully extend to the perimeter of the factory engine cover. In addition, vehicles built on a Ford chassis may have higher engine compartment temperatures during certain idle conditions. This may result in elevated temperatures at certain areas of the engine cover surface in the passenger compartment on both driver and passenger sides. Direct and continuous contact with exposed skin at these locations may cause skin irritation and/or a minor burn. This affects the following Thor Motor Coach products: model year 2021/2022 Axis, Chateau, Coleman, Daybreak, Four Winds, Freedom Elite, Magnitude, Majestic, Outlaw, Quantum, and Vegas motorhomes

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
