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.

The defect: Winnebago Industries, Inc. (Winnebago) is recalling certain 2017 Brave, 2019 Itasca Sunova, 2019-2022 Adventurer, and 2022 Sunstar motorhomes.

The risk: A small lens can make it difficult for other drivers to see the turn signal, increasing the risk of a crash.
The remedy: Dealers will replace the turn signals, free of charge. Owner notification letters were mailed May 8, 2026. Owners may contact Winnebago Customer Care at 1-800-537-1885. Winnebago's number for this recall is 203.

Body & structure
Filed Feb 25, 2025

The front grill fell off the vehicle while driving. I was actually in the process of bringing it to a service center to have the hood bracket reattached. I had also fell off and is currently subject of a recall (NHTSA campaign number 24v826000). I was able to retrieve the grill and on inspecting the brackets that hold the grill on, there was no adherent epoxy suggesting it failed to bond correctly (which was also the issue with the hood brackets).
