Wow....I cranked mine yesterday after 30+ hours of not driving and it was off too. I drove 4 different times yesterday and it remained off. Please post what the dealer says the codes are. Im going to wait to see if it comes back on before I go to the dealer. Thanks!

Same exact thing for me! 2019 Sierra SLT - 5.3 / 8 speed and 12.7K miles. Normal driving into this past weekend, then yesterday...CEL on with no drivability issues. I had not got gas in a week, but thought about the same thing with the "lose cap issue" on older models. I'm going to give it a few days, get codes pulled and then contact dealer if it stays on. *** mine is not related to a remote start.

Stopped shortly after driving off the lot on a rainy day last month to snap these pics. Pacific Blue, Stock SLT with premium package. Love the truck so far!
