"DEF low, but you know it's not" problem
We added DEF to our 2012 Chevy D/A before our last trip and off we went...Over 500 miles later we got notice that we had 300 miles until we added more...Didn't think that sounded right, but added anot...

My 2011 had the same problem twice now in 40k miles, both times it took a complete system replacement. Asked the Service Manager if this was going to continue or if Chevy had fixed it, his answer was, you can continue to expect problems and once out of warranty plan on 2k per occurrence.
