Went to marrysville peterbuilt and was told that dpf needed cleaned .so I did.well 3 days later I got truck back and my windsheld was cracked from bottom up.they was the last to drive my truck.and service manger never. Called me back to this day.so went down road and truck went in to home limp mode in bosie Idaho. Took there and they found the real problem.bad wires and load battery connections. And a few missing bolts.i was charged for new clamps and old ones where put on instead. And the service manager Katie has never called me back.but was told since my truck was outside gate that they would not fix my windshield.bosie Idaho peterbuilt is the best .spent a 1000 dollars and was done right.
