One problem related to other fuel system tank assembly has been reported for the 2014 Chevrolet Express. The most recently reported issues are listed below.
I have a fleet of 2011-2015 Chevrolet Express diesel cargo vans for my business. Each of them are on their 3rd replacement of the def tank heater kit gm p/n 84412924. It seems to die after use in the 80,000 mile range. Seems to be a poorly designed part having to do this.
