Well the light come on and said water in fuel service truck. 2017gmc 3500 duramax. Well no water in fuel apparently iam the first truck in Canada with this issue. Wonder if I get a prize lol
You probably have a bad water sensor. You do get the prize for finding that one bad unit statistics predicts is out there, no matter how well designed and built or how thoroughly tested a product is. Oh, your prize? A trip to the truck store for repairs. Should be covered under warranty.
