My 2019 Cherokee Trailhawk is Coming Up on 10,000 at 1 Year Old. The 3.2L V-6 has been Perfect so Far. The 9 - Speed Trans Has Done about 6 Strange Shifts So Far. Nothing Real Bad, but Slightly Irritating to a Retired Tool & Die Maker. I've Put about 800 Miles driving my Sister in Laws 3.6L V-6 Pacifica and a about 200 on My Daughters Pacifica. I Can Say that the 3.6L has More Low End Torque and More Power at High Rev's than My 3.2L V-6.
