Truck has had multiple ‘service emmision system’ errors which can leave the driver stranded and left in traffic as the truck gs into limp mode and won’t maintain speed with traffic flow. There are electrical glitches and issues with the circuits and heating elements themselves and in the pump… as soon as there is an error in the system… which has happened 3 times now in 104k miles (~80, 103k and 104k)… the truck is rendered useless and stuck in traffic. Emmisions system needs to be covered for the life of the vehicle if it is going to have non stop issues.
