Grand Design Serenova: Powertrain

Affects Grand Design Serenova · 2025 — about 14 vehicles.

The hazard

Issue: On certain RV trailers, the axle nut(s) may have been over-tightened. As a result, the wheel bearing could overheat and fail. If this happens, the wheel(s) could loosen and separate from the trailer. Safety Risk: A wheel bearing that overheats could create the risk of a fire. A wheel separation could cause a loss of control and increase the risk of a crash. A wheel that separates could also hit another person or vehicle. Corrective Actions: Grand Design will notify owners by mail and advise you to take your trailer to a dealership to inspect the wheel hub assemblies. Any damaged parts will be replaced.
