What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2026 Keystone Cougar, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
From owner reports, verbatim
Camping world Hamburg delivered to me fifth wheel they Ammit they did not have inspected causing Catastrophic structural frame failure and pin-box cross-member buckling (Frame Flex) engineered within the upper deck chassis frame. This structural failure has caused widespread, secondary body panel collapse, including deep spiderweb fractures tearing through the upper fiberglass radius wall paneling, vertical trim moldings violently warping and splitting open, and the upper passenger-side roof cap seam ripping completely open. The failed components have been placed under an immediate "no-tow" safety mandate to preserve evidence and are fully available for a driveway physical evaluation or engineering laser-scan upon request at my residence.
