  • The recoil from a sudden and unexpected wire rope failure could result in death or serious injury to the winch’s users or bystanders. A wire rope failure during winching could also cause the user to lose control of the vehicle.
  • The XD9000i was unreasonably dangerous because the user or by standers would be exposed to the hazards produced by the failure of the wire rope with no prior indication that the winch had been overloaded.
  • The Warn XD9000i winch failed to make a single continuous pull of a nominal 6000 lb. load lasting more than 3 min. without stalling the winch motor.
  • When repeatedly operated to full stall and allowed to cool after stalling, the Warn XD9000i winch failed to pull a nominal 6000 lb. load for more than a total combined time of 6 min. prior to electrical failure.
  • Warn did not incorporate any automatic circuit protection device into the XD9000i winch system. The XD9000i winch relied solely on the user to determine when the winch motor or relays had been overloaded.
  • The retrieval tests demonstrated that the average unloaded stopping distance was 16.5 in. for the XD9000i and 40.8 in. for the HS9500i.
