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.

Latest Mar 20, 2025
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.

Filed Jun 30, 2026

I bought this RV as a new 2023 Thor Quantum MB24 . After a recall performed by Mercedez of Pleasanton , California ( after the VIN no. was punched on their computer ) , it shows as a 2021 Model year . How would I know if I was sold a pre - owned Motor Vehicle or a new one ? It has 2000+ miles in accordance to RECVAN @ Fremont , California , was acquired driven from Elkhart , Indiana to California . There were few issues and problems that I found out later after I had the RV parked outside my resident in Mountain House , California : Dirty outside compartment , Inoperable Navigation system , left outside wheel hub cap held by a single screw , all 4 rear wheel air valves not working properly , dream dinette can not turn to bed due to improper fit , some outside compartment latches loose , shower curtain had tiny slits , missing toilet bolt cover . Most of this issues was taken care of as part of the warranty . My concern is why is it a 2021 year model and not 2023 as per VIN NUMBER ? I s it Pre- Owned ? I don't have any way of knowing , hopefully you can help me with this issue . Thanks Respectfully , [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Manufacturer communications

A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.

TSB 22-12

EQUIPMENT; STRUCTURE

Wood stiles are delaminating due to the vendor changing the glue used for the wrapped stiles.

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.
