What's wrong?
The wheel nuts on the 2024 Doosan Portable Power Mobile Generator hold each wheel tight against the hub while the generator trailer is being towed. They are simple hardware, but they do a safety-critical job: the clamp force keeps the wheel seated as the tire carries road load, braking load, and vibration.
On affected PG25 generator trailers, the lug nuts were not tightened to engineering specification after a frame assembly station move in January 2024. Too little torque leaves the wheel loose on the hub. As the trailer moves, road vibration can let the nuts loosen further, creating wheel wobble. If the wheel is no longer held tight, it can separate during towing and lead to a crash.
Owners have warning signs to watch for before failure. Vibration or tire wobble while towing means the wheel hardware is not holding the wheel steady. Stop towing and have the lug nuts checked and torqued before the trailer moves again.
