I didn’t go through a dealership but I trusted my mechanic to get the right stuff. I ended up hunting down a fuel pipe for it though and it was an “updated” part number

I know this is an older post but found some related info that might help some. My son's 2016 silverado started the cold start code but was running OK, we found N182198000-Special Coverage Engine Fuel Injector bulletin dated 26 July 2019 for 2016-2017 Caddilac, Chevy and GMC trucks/SUVs. It is worded oddly, stating it only affects vehicles in 13 states ( California, Connecticut, Delaware, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, and Washington) but seems to indicate GM is acknowledging at least some fuel injector issues.

 

He took his truck in and of course the dealer could not replicate the issue and sent him on his way but he's just waiting for it to throw the code again to take it back and see if they'll actually fix it. I'll post an update if we get one.
