Other Fuel System Fuel Injection System problems of the 2017 Chevrolet Silverado 1500

A few months after purchasing from dealer check engine light came on solid. Brought to dealer. Vehicle was shaking and running rough. . Dealer diagnosed issue as faulty fuel pressure sensor. They replaced the part through my extended warranty. A few months later the check engine light cane on blinking same issue vehicle shaking and running rough. Took to dealer immediately. They diagnosed as bad fuel injector. They claimed the ecm went bad caused by the bad fuel injector. They replaced ecm and fuel injectors costing thousands. They convinced me I had to pay for a "platinum fuel injection service" after it was replaced. This was another $300. I was promised the issue was fixed. I was told if check engine light came back on for same issue it would be covered "under good faith". . . Well 2 weeks later the check engine light came back on after hardly even using the truck. . . I had my family in the truck for a planned family even and had to pull off in the sweltering heat to pay for a tow truck to come get my vehicle. . . . Now it sits over at the dealer again. . . They want me to pay a diagnostic again. And it has not even been looked at. For the amount I paid for this truck it is dangerous untrustworthy and embarrassing. After reading all these complaints for fuel injectors gone bad at early life, why is this not recalled?.
