The fuel pump driver module. I filled my truck up with diesel and it drove home fine. Later that afternoon left the house and got half mile down the road and the truck just shut off with no warning lamps or message. When this happened, you could not steer the truck and the brakes barley worked, now after the truck cut off a message came to shift in neutral. I was lucky no one was on the road at that time. Now had this happened the day before when I was coming home pulling a 40ft fifth wheel, this could have been catastrophic. When this fuel pump module goes out you have no warning the truck cuts off and you have no steering or brakes. This module needs to be recalled, and something else done to have some kind of warning before everything shuts off. People get these trucks to pull things and sooner than later Chevrolet will be answering to a fatality due to this fuel module, this does not need to be ignored till this happens.
Received a code p10d9. Infotainment center says 157 miles until 65 mph max speed. Dealer has no idea what’s wrong.
2nd time I’ve had to replace def heater and tank. Truck goes into limp mode and limits the speed leaving a person stranded.
Gm recall n2123544170 dpf regeneration temperature /def heater for cold weather operation to keep def from freezing and also for thawing frozen def. . . Dealer to replace def tank and internal heating element. . . Dealer was unable to give a time line for replacement parts needed to fix truck. (parts are back ordered)so truck ecm=electonic control module. Throws trouble code to reduce engine power that starts taking away engine power at 65 mph. . . Then 55 mph. . . Then 45. . . All the way down to 5 mph. This can happen at any time or anywhere that can result in possible accidents. . . ! gm needs to make this a priority as thousand of vehicles are affected!.
