I've been having transmission issues which cause harder shifting than usual. upon research, I found that the 2016 GMC Sierra's have a special coverage that replaced the transmission harness which throws the code P0711 for the temperature sensor and P0700 which is the generic transmission code. The only difference between my VIN and the VINs covered under this special coverage is that my Sierra is a 2015, everything else is the same down to the part number of the known faulty transmission harness.

FUEL/PROPULSION SYSTEM
When driving leaving my home and about 2 miles in operation the truck lost power. Not realizing quite what was happening looking at the instrument panel I noticed a drop in RPM and speed. There were no other indicators of problems and The check engine light didn't come on. Instinctively i pushed the accelerator down with no response. Now realizing that the truck was having problems I tried to get off the road. The area of malfunction was not a good place to stop and did the best I could, the truck half out of the traffic lane. In trying to restart the truck which turned over but would not restart. I felt it was acting like it ran out of fuel, checking the fuel gage which indicated 3/4 tank. The truck was towed to the dealership. During the intake conversion the employee stated " it's probably the fuel control module " which I thought was odd at the time with no one even looking at the truck. Finally results was the fuel control module. I am thinking back on how the truck abruptly came to the stop that I was not in a center lane of a busy highway. In my research I have noticed that there seems to be an updated part number and replacement for this OEM fuel module. I did order a spare to have just in case this happens again. Few things I find interesting is that the dealer knew what the problem was during intake, had one on the shelf and replaced it and had me going the next day. This incident i surely wouldn't want to happen to my wife, anyone on a busy highway or other unsafe situation that the engine needs to in operation.

STRUCTURE:BODY
Driving on the highway, the upper grill molding on the leading edge of the hood broke off and came up and hit the windshield and top of the cab. Upon further research online, this seems to be a pretty common occurrence on sierras with the at4 trim package. I was told by the dealership that extended warranty does not cover this and I would have to order an entire new grille, over $1000

AIR BAGS
General Published an article about the Takata Airbag recall stating that the dashboard would be inspected prior to doing the recall work and if already cracked or damaged the dashboard would not be replaced. My dash board is like new with no damage or cracks. The dealer told me (contrary to this article) that if their service men damaged my dashboard while doing the recall replacement I would be responsible for any replacement even if my dashboard is in perfect condition prior to the work. I find this unacceptable and will not have my airbag replaced under these conditions. The dealer/GM should be responsible for any damage they cause during the repair.

The vehicle will be in the park position and a warning on the dash will say shift to park not allowing you to shut off the vehicle. Jiggling the shifter sometimes works but often have to restart the vehicle numerous times to get the error message to not appear and be able to proceed with shutting off the vehicle
