Faults:

I have had this truck since new. Two major complaints.

The first was the DEF system. Have had issues all along from check engine lights to replacing heater elements, to injectors. Up til now the expense has been over $2,500.

However the big problem just hit with the Bosch fuel injection pump failure. Estimated cost $9,000. Just saw a class action being started on this issue covering diesels from 2011 to current. Huge possible problem. The truck had been "okay" up till then.
