I am deleting my Duramax diesel truck tomorrow. Yep, had a problem with the DEF tank pump about 4 weeks ago. GM covered it under the warranty but it was an eye opener to the future ownership of a modern diesel truck. Repair, repair repair and in another year on my dime. Basically emissions component failure has all that has happened to it in 4 years of ownership. I'm sick of the stupid regens every 700 miles and getting 10-12 mpg while it does this ignorance. Very tired of having to buy DEF fluid which is 37% piss anyway. Then there is the breakdown problems with all of this failed technology that was forced on the manufacturers 10 years ago by another failure in leadership.
I'm not looking to blow soot clouds like the young idiots are so known for now days. Nope I just want a truck I spent $70k on to last and not stay in the shop for BS repairs. Tuned accordingly diesel trucks do not normally blow large clouds of soot. And NO emissions testing in MS.
