Defect
On certain cutaway chassis vehicles equipped with 6.8L engines and optional trailer brake controllers, during tow operation, the integrated trailer brake controller may not actuate the trailer brakes when the driver depresses the brake pedal. There would be no warning to the driver that vehicle braking does not actuate the trailer brakes, which could increase stopping distances, potentially resulting in a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will reprogram the powertrain control module.
