2014 Chevrolet 1500 needs new injectors at low mileage?



2014 Silverado has 47k. Engine light came on with code for cold start/ rough idle. Dealer ran check and said four fuel injectors need replaced. How at such low miles?


May be an issue with the Displacement On Demand system. The system that shuts off 4 cylinders to improve fuel economy. Without knowing which injectors need replacing, it is just speculation on my part.


What was the actual code or codes?
