    They don't handle vibrations well. Out of balance tires, alignment, leveling valve issues, wreak havoc on anything that dangles.

    So if anyone is interested on what happened. Picked the truck up from the dealer (took them to long to even start, they did diagnostics and charged me $450).

    Got the truck to my mechanics and they changed ...
    Def pump
    Def pump harness
    In & out NOx sensor
    And the ACM (the computer located on the def tank)

    After that everything seems to work...

    Total damage to my wallet : $3800 + 450 from the dealer ... $4,250 (for that amount also had a couple little things also done changed the alternator and tensioner ... couple air leaks fixed)

    Well at least you're good to go for awhile now. Get some of that money back now.

    What fault code are you getting. And I have seen a recent video of a def pump on a Volvo where it cracked internally due to the cold causing the def to leak at the connector.

    5394 is the code, it's generic and covers a lot of things with aftertreatment. The DEF pump is made of plastic cuz apparently the def is caustic to a metal pump, so consequently you have plastic and a liquid that freezes. Not a good match.
