I’ve been hearing a high pitch whining when accelerating semi aggressively. From a stop if im accelerating quickly you can hear it make a whining noise until it gets out of first gear. On the highway if I’m passing, I can hear a faint whining noise in the higher rpms(5k-6k rpm)in any gear but the noise is not apparent in the lower rpm’s when cruising . I’ve been noticing it more and more lately and wondering if anyone having similar issues. I do in fact experience an occasional rough down shift when stopping but that seems common. This is on my 2019 Grand Cherokee 3.6 altitude 4x4 with under 10k miles.

Yeh......I think I've heard what your are talking about in my new '19 Limited. Only heard it a few times when I turn out of my driveway and romp on it pretty good to get up to speed on the highway. Only hear it for a few seconds and high RPM in 1st gear. I've only had the car a few weeks so I will keep an eye (ear) on it.
