Equipment

Nov 22, 2017 · NHTSA campaign 17V758000 · 110,400 vehicles

Problem: 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.

Risk: In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.

Equipment

Oct 9, 2017 · NHTSA campaign 17V634000 · 507 vehicles

Problem: Thor Motor Coach (TMC) is recalling certain 2017-2018 Challenger, Axis, Chateau, Four Winds, Hurricane, Miramar, Palazzo, Tuscany, Vegas, Venetian, and Windsport motorhomes. The cargo carrying capacity (CCC) label on these vehicles may indicate an incorrect water capacity for the water heater/fresh water tank. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 120, "Tires and Rims for Motor vehicles over 10,000lbs."

Risk: If the water capacity information is incorrect and it causes the vehicle to be over loaded, there would be an increased risk of a crash.

Trailer Hitch Receiver Structure May Crack and Separate

PE24023 · opened Aug 14, 2024 · closed Jan 16, 2026
Summary

The Office of Defects Investigation (ODI) opened this Preliminary Evaluation, PE24023, on August 14, 2024, to investigate allegations of Thor Motor Coach motorhome frame or trailer hitch structure cracking and separating. The hitch was manufactured by Lippert and installed by Thor as standard original equipment. ODI received eight Vehicle Owner Questionnaires (VOQs) describing the hitch structure cracking. If not caught in time, a cracked hitch can fully fracture and separate from the vehicle. ODI sent information requests to Thor and Lippert on September 6, 2024 and September 27, 2024, respectively. Thor's full response was received October 31, 2024, and Lippert's full response was received December 6, 2024. ODI reviewed the responses and learned of improvements introduced to increase the overall strength of the system. The manufacturers reported 32 total incidents, and ODI is aware of 37 non-duplicative subject vehicle incidents in total, including four crash incidents where the towed vehicle separated and struck a roadside feature. The overall failure rate for all subject vehicles is low, and ODI isnot aware of any failures on vehicles produced in the last 30 months. Although a defect has not been identified, the manufacturers understand the seriousness of a potential hitch receiver structure failure. As a result, Thor, supported by Lippert, is conducting a customer satisfaction campaign that instructs consumers to inspect their hitch structure and informs what to look for…
