GMC Suburban owners have reported 1 problem related to other fuel system fuel injection system (under the other fuel system category). The most recently reported issues are listed below.
Injector pump failure causing the vehicle to just stall when going down the road. It happened to me the last hot weekend this fall. The local dealer took my vehicle & had it for over a week, finally getting a code to show up that allowed them to replace the injector pump. I don't believe that the injector pump was at fault, but instead the pmd electronic control module was failing. This replacement didn't cost me anything, but I think gm should extend the warranty for a much longer period of time because of the known problem. They extended the warranty to 120,000 miles on an engine that is designed to run 200,00+ miles w/proper care. My vehicle has approx. 50,000 miles on it at this time.
