When accelerating I hear a exhaust/diesel chirping sound . I put it in manual and it does it . It' not a hemi tick . I have tracked other hemi owners down in my area and their truck doesn' make this noise . Is there any fix ? It only has 16k on the engine and it seems to be getting slightly louder since starting at 12k miles on it . Of course it amplifies when a car , barrier , wall is beside me . Thx for any help , has full warranty and dealership will fix but they act like they don't know the cause .
