I have a 2021 1500 echodiesel with 41k. I had to have total fuel system replaced at 26k. now the check engine light is on again and it says 4th glow plug stuck open. is this a major problem or can it be driven without repercussions. I am leaving for a 2000 mile road trip in a week and of course, can't get into a dealership till end of Sept.

Glow plugs don't open. They are passive elements, activated electrically for start-up.
Fuel Injectors can be open/closed
My CEL never went off in the years I had the DEF/DPF on. Until the dealer replaced the NOx sensor and the engine cratered a few weeks later.
