Does my truck have DFM?
Hi all,
New to the forum. Not new to Chevys. I recently bought a 2019 Silverado Custom. I know it has the 5.3 and 6 speed transmission. When I bought it, I made the assumption that it had DFM. I bought off Carvana. However, since purchasing it, I've not been able to confirm it. My wife has a 2016 Tahoe and it flashes "V4" or "V8" on the dash. So I know it does. Her average fuel mileage is 20 mpg. Mine is 17. I have no indicator lights or anything else on my dash that make me think DFM is on. Are there any other ways to tell? I was under the impression all the 5.3 in this year range had it, but then I read some did not. Any help would be appreciated. Either way I love my truck. I am just curious.

you're thinking of the 2021 pandemic chip shortages.
Yours has DFM.
