won't fix the def problem. I had to take it another 200 miles to another Freightliner where they replace the def head for 1500$ and tell me it's going to happen again! You guys have to do something about this. If not the people will put Cumming out of business. It's no way to run a country letting this crap get by. Please fix it!
While operating my vehicle, the rear tail lights and brake are completely inoperative making my vehicle unsafe to operate. The engine radiator cooling fan electrical clutch becomes inoperative and no front air conditioning.
(Report previously submitted 18 april but may have inadvertently been deleted). At about 31,600 miles on my rv (2009 forest river berkshire mounted on a freightliner chassis with cummins 350hp engine), the engine suddenly overheated. During repair at a freightliner facility, three of four retaining bolts were discovered broken on the fan hub mounted on the back of the engine; the fourth had backed out several threads and the fan tilted into the shroud and seized in place. Freightliner repair technician stated...

their facility had made several repairs on cummins/freightliner chassis rvs; the failure occurs with some frequency; the bolts and design of fan hub appear to be inadequate for loads applied by the serpentine accessory belt; and that failure of all four bolts could shatter the fan blades when it seizes in the shroud resulting in shrapnel damage to the radiator and severed electrical and fluid lines. Further consequences could include a need to quickly exit traffic flow to avoid becoming a collision hazard. From my understanding, the fan hub, fan, radiator and other accessories are added by freightliner to the cummins engine during chassis manufacture. Repair requires considerable and expensive removal of engine accessories. Use of this cummins/freightliner chassis configuration by other coach manufacturers is unknown. Technician on my repair drilled and tapped a fifth bolt to strengthen the fan hub. Online forum inquiry and interest from other owners suggests similar experiences. One other owner learned that freightliner is aware of the problem, that they have no recall but they have a five bolt fan hub for purchase that evidently addresses a load failure problem with the four bolt design. *Tr
My 2008 forest river berkshire 390qs motorhome (freightliner chassis with a cummins 340 hp, 6.7 Engine) with 13,200 miles on it suddenly overheated fortunately on a 2 lane road. The unit was towed to a repair facility where the service manager informed me that the 4 bolts that held the fan hub in place had sheared causing considerable damage. He informed me that in his opinion 4 bolts cannot handle the stress placed on the fan hub. He further suggested that I contact freightliner to see if there was a recall on...

this. I proceeded to do that and found out that there is no recall but was told that they do now offer a new fan hub with 5 bolts. This tells me they are aware of the problem but are not going to do anything about it. I further found out on the forest river forums website that others have had the same problem. I feel that this is a safety concern as the bolts could again shear off while traveling at higher speeds on an interstate highway causing accidents, injury, and, perhaps, death! Costs to repair this work is considerable as it requires removal of engine accessories and internal flooring. I have no idea as to what other manufacturers have the same chassis and engine configurations as I have. *Tr
