I’ve seen chatter about this issue on the Facebook Silverado clubs. I’d start there and ask around. ---

Maybe a bad DEF level sensor? [https://dirtyhookerdiesel.com/i-24076552-gm-20760381-def-level-sensor-temperature-module-lml-cruze.html](https://dirtyhookerdiesel.com/i-24076552-gm-20760381-def-level-sensor-temperature-module-lml-cruze.html) Tester ---

2015- I believe this will still be under warranty, unless you have put a ton of miles on them. The emissions system should be 8 years, and whatever miles (sorry, I’m not sure off the top of my head.) Look in your owners manual to be sure on that. I had this with a 2014 Chevy, and was able to use my OTC Genesys scan tool to force a reset on the level sensor, and it has been fine since. Somehow, it just didn’t ‘catch’ when the level was refilled. A good shop with the right diagnostic equipment should be able to do this- but I’m almost positive that this cannot be done with a basic scan tool. Mine was $4000 some years ago, plus GM software. If the sensor is bad, I just replaced one in a 2010 Chevy. It wasn’t all that difficult, but the part was over $300. ---

> [@eddo](#): > > . The emissions system should be 8 years, and whatever miles The only emission components warranted for 8 years/80,000 miles are catalytic converters/engine control computers. Tester ---

ahhh Tester, you made me go and look, lol According to my owners manual: If OP’s state adopted California Emissions Quality Standards, than some of the emissions system is covered for 7 years, 70,000 miles (my apologies for saying 8.) These states include Connecticut, Delaware, Maine, Maryland, Massachusetts, New Jersey, Oregon, Pennsylvania, Rhode Island, Vermont, Washington, and California.(and possibly New York.) This 7 year warranty does appear to cover the DEF tank, but doesn’t say anything about the Level/Quality/temp sensor. so I’d still tell OP to check with their owners manual and dealer. (assuming that no modifications have been made to the emissions system.) ---

> [@Tester](#): > > I was referring to the **FEDERAL** emission warranty. > > Tester cool. Guess Chevy recognizes a broader warranty, Which is what I was referring to. Good for Chevy. as I said, OP needs to check this out for themselves to be positive they are or aren’t covered.
