2020 Duramax recall post mpg
Hi all
A couple months ago I had the recall performed on my truck that had to do with def. Since then I have experiencing lower mpg’s in the range of 10% lower on average. I called my dealer and advisor said there have been many complaints regarding this but no fix.
Anyone here experiencing this and have any info?
thx
