I have 2019 Ram 1500 4x4. At startup it sometimes makes a banging noise. I thought it was a backfire but dealer and FCA now say it's random clutch application applying torque to P4 carrier and attached parking gear. The noise is the parking pawl making contact with a parking gear tooth. Does anyone have similar problem? Only 20K miles and I am not happy with dealer and FCA response. I have filed a lemon law compliant.
