NHTSA recall 07V548000
Structure › Body › Roof and pillars
Cottrell C-8ENC
The defect
On certain car haul trailers that are equipped with roofs that raise and lower, the roofs are attached to a raising/lowering mechanism by round tubes that are welded to the roof. there are 4 tubes welded to each roof and 2 roofs per each complete piece of equipment. the base material around the welded connection may experience a fatigue failure during high mileage operation.
The risk
Should failure occur on all four lift points, the roof might separate from the trailer increasing the risk of a crash to following vehicles.
The remedy
Cottrell or a repair facility authorized by cotrell will add an additional weld pass around the roof lift tube, install an inner and outer gusset tying the roof into the roof lift tube free of charge. the recall began prior to november 21, 2007. all owners have been contacted.
