John L Sullivan Chevrolet Chevrolet capless Fuel system design flaw Roseville California

 2017 Chevy capless Fuel filler neck has a design flaw which allows water and road grime to collect and puddle on top of the. Filler neck. When fueling all debris which has collected enters the tank contaminating the fuel that will lead to plugging fuel filters and possible damage to the fuel system I took my truck back to the dealer John L Sullivan , which was a waste of time as they told me that's the way Chevy engineers the truck and there is nothing they can do. Along with the issue of contaminated fuel we have no way to lock our tank to prevent children or vandals inserting foreign objects into the tank
