Vehicle shifts hard when not under power. When under power vehicle backfires,mis fires, loses acceleration completely. Have brought vehicle to deal 4 times and have been told there is nothing they can do. There is black sut on the exhaust. I do not feel safe driving in the vehicle if it cannot accelerate or will just completely shut off.
