Recalls, owner-reported complaints, investigations and safety data

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.
0
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.

Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

VISIBILITY:GLASS, SIDE/REAR

Jun 9, 2020
71 units potentially affected
The defect: Thor Motor Coach (TMC) is recalling certain 2020-2021 ACE, 2021 Four Winds and 2020 Gemini, Axis, Compass, Delano, Windsport, Hurricane, Outlaw, and Vegas motorhomes. The adhesive bond between the glass and the metal hinge frame of the frameless windows may fail which would then allow the glass to detach and fall out.
The risk: If the window glass detaches while the vehicle is moving it could become a projectile, increasing the risk of a crash.
The remedy: TMC will notify owners, and dealers will inspect the frameless windows for proper adhesive bond strength, replacing the windows as necessary, free of charge. The recall began July 10, 2020. Owners may contact TMC customer service at 1-877-855-2867. TMC's number for this recall is RC000192.
