Thank you to all that have replied and shared how your brand is treating you, I really do appreciate your input. Thank you.
As I stated will not trust my life or my family's to a maybe block, piston, rod, crank, etc. They had the engine tore down, the parts that could fail and injure someone should have been inspected. I will be towing through the mountains, not chancing a runaway. And 2 overhauls in 50K miles on a diesel is serious.
1st vehicle is sold by the salesman, no issues, following vehicles are easy sales. When an issue arises remaining vehicles are sold by service department or in serious cases manufacturer.
