PE24023 · Trailer Hitch Receiver Structure May Crack And Separate
Opened Aug 14, 2024 · Closed Jan 16, 2026
Status: closed (inferred from source dates) · Structure:frame And Members; Trailer Hitches
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 and what to do if issues are found. If consumers areuncomfortable performing this inspection, Thor dealers can inspect the trailer hitch for them. The inspection and repair will be done at no expense to the consumer. ODI is closing this Preliminary Evaluation (PE) with this manufacturer action. 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.
