So my 21 has 15k on it in 1 year of ownership. I really like my truck but I’m sorry, I just don’t trust the stupid Gubment Motors Fuel management system. I’ll probably hit mileage before 3 year warranty but when I do and if I still own this machine I plan on getting rid of their crappy ( May implode at any moment) 2 piece lifter scam… I mean set up. It’s a shame that this has to be done but it has to for me. Has anyone done this or Had it done?
