Took to dodge dealer and they told me they have been have problems with traction control, 4×4 problems, misfiring cylinders . They spent 5 days trying to figure it out and told me it was a process of elimination . Replace rear diff motor and that didn’t work, replaced TCCM, that didn’t work, replaced both batteries , that didn’t work, new spark plugs, that didn’t work, replaced coils on the side where #1 cylinder miss fire, that didn’t work. I’ve spent approximately $6,000 and still have same problem. I do not have unlimited funds. What should I do next?
