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.

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.

PE20021ClosedPreliminary Evaluation

Trimark 060-1650 Door Latch Failures

Opened Nov 23, 2020
Closed Dec 13, 2024

On November 23, 2020, the Office of Defects Investigation (ODI) opened PE20021 to investigate allegations of inoperative Trimark THP 060-1650 door lock/latches originally equipped on model years (MY) 2015-2017 Class A and Class C motorhomes.ODI received forty-six Vehicle Owner’s Questionnaires (VOQs) describing consumers being locked in or out of their vehicles.The door latch, containing a die-cast zinc plunger, was produced by Equality during calendar years 2014-2016. The die-cast may become porous and brittle over time and can break without warning, causing the vehicle owner to be unable to open the recreational vehicle door equipped with the latch.If the motorhome does not have any other doors such as some Class A models, occupants could be trapped inside, needing to climb out using the emergency exits. If locked out, owners would be unable to easily get in and retrieve children and pets. ODI analyzed the data provided by Trimark in response to its January 27, 2021 information request letter.Although an elevated failure rate was evident on a specific combination of plunger bolt, door lock/latch assembly and door, the data showed that most failures occurred within the first two years of service on the affected 2015-2017 vehicles.This data suggests that component failures generally would have already occurred.Further, ODI data reflects a downward trend in complaints after calendar year 2018 and for post- MY 2016 vehicles.This downward trend may be attributed Trimark's actions in 2016 such as changes in the manufacturing process of its zinc plunger component for the relevant population and its 2016 decision to switch to a steel plunger. In view of the nature of early-life failure, and failure rate trending downward for model years 2017 and newer, this Preliminary Evaluation (PE) is closed.  The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The Agency reserves the right to take additional action if warranted by future circumstances.

Fire reported

We have been experiencing multiple issues with the electrical system in our RV. There was a serious safety event to took place, where the wiring box under the bed created smoke and we could smell plastic burning. When investigated by my husband, he found that the box under the bed that housed all the wires for the RV had burn marks on the inside of the box and the wires and wire caps had melted. Then we started having issues with the generator not working, and were unable to use the generator. We had to pull the generator and taken it too a generator repair shop and found that the wires inside the generator were melted and were told it was unrepairable. The dealer that we purchased the RV from, will not help us. But this has to be a big issue with this model because we had met someone from a camp ground that had the same RV and they had to same electrical issues.
