I have a 2020 Laramie sport. I have same whining noise. I live in Ontario Canada. It is quite loud on cold starts. I have been planning on getting it looked at

There's a different exhaust sound between the non and e-Torque Hemis?!
Not normally, but her Limited has stock exhaust and my Laramie has an aftermarket muffler.

Mine makes as much noise as an alternator, meaning none that I can hear. If you can hear it, I would absolutely assume something is wrong.

I have a 2019 Big Horn that has also developed a low pitched whine noise at 700 RPM. I have taken it to several auto shops as well as the dealership who all say they either can’t find where exactly it’s located and/or it doesn’t sound concerning. This noise began immediately after the PCM, TCM, and HCP were updated. Any thoughts?

Owner 2021 ram 1500 limited night edition with 8300 miles. Since purchase I started hearing whining noise between 500-700 rpms. Took to dealership of purchase and they said it was normal after having me sit in another Etorque. They said it’s related to generator charging hybrid battery while idle. I somewhat reluctantly agreed but annoying sound continues. I am still in process of investigating into this. Does anyone else with Etorque 5.7 L hemi have this problem? I’m planning on driving this truck for many miles but concerned this noise is associated with problem that may come up later after warranty expires $$$$.
Also for truck at price point of 72K it seems not right to have such an annoying noise to be normal.
I've been dealing with the same issue. Its very noticeable at 700 rpm I've been told the same story about it being a characteristic of the Etourqe but I'm doubtful. It sounds more like a loud transmission hydraulic pump or a faulty bearing somewhere. I've tried to locate the exact location where the noise is being produced but it doesn't seem to emanate from the etourqe. It seems its most loud around the aluminum driveshaft almost like its ringing causing the noise to be amplified. Let me know if you get anywhere with the dealership. Good luck.
