general problems of the 2011 Chevrolet Silverado 3500

Diesel exhaust filter (def) and flow reduction tube on duramax lml engine. Fautly def requires extremely high temperatures to clean - or regenerate - causing the def and reduction tube to fail. High temperatures are a fire hazard to vehicle and grass or other terrain over which the truck is parked. Gm no longer manufactures the reduction tube, gm part number 25960609 forcing the consumer to wait for gm to make part on special order basis - over 30 days - or force consumer to remove def or make other fabrication, order to operate the vehicle. Gm is aware via customer service and dealer complaints that the lack of part 25960609 availability is a nation-wide problem and has a high failure rate. Gm stopped production as a cost saving measure. The duramax lml engine is in service mostly as commercial vehicle fleet. Thus, there is a high probability of unsafe fabrication in order to restore vehicle operation.

Ibc ( integrated brake controller ) factory installed is not compatible with trailer braking systems using a eoh ( electric over hydraulic systems) however according to reports on various web sites and going to a gm dealer their recommendation is for owners to have installed at our ( owners ) aftermarket brake controllers with no compensation , people that have bought these trucks were not told by the dealers who were/ are aware of the incompatibility issue and has caused financial burden to the owners , however the new 2016 have had the problem corrected and have offered no solutions to previous year owners other than the aftermarket controller expense . This issue almost caused me to have a catastrophic collision if I had not had the thought and awareness to drive off the road into a ditch which incurred upon me a $850 towing bill to get back onto the highway. I bought the truck in July of 2015 used from a dealer in tallahassee ,florida and had not used the truck for towing a trailed until the date of the incident!.
