ETorque noise in my 2021 RAM Night Edition

[NunenCamen]

Anyone else out there driving a 2021 RAM 1500 (Etorque, 5.7L Hemi) experiencing a whining noise between 500-700 RPM? It's there since I bought it new. Dealership says it's normal - something about the generator charging the battery - but after listening to another Etorque, I'm not convinced. This whine is kind of annoying, especially for a truck with this price tag! More importantly, though, I'm worried it might be a sign of something more serious down the road. Anyone else have this experience?

I don't hear any noise. Only noise I hear is my wife complaining about my driving

The whine you’re hearing is actually a known trait with the Etorque system, especially around 500-700 RPM. Some people are sensitive to it, some aren't. It’s related to the motor-generator unit charging the battery, which creates that high-pitched noise. The dealership is right—it’s a normal part of the system’s operation. You’re not alone in finding it annoying, but mechanically, it shouldn’t cause any long-term issues. If it starts getting louder or more frequent, it might be worth a deeper look, though.

exact same experience with my 2021 Etorque! That whining noise bugged me for a while, but after doing some digging and listening to other trucks, I found it’s just part of the system. That said, you might want to try adding soundproofing in the cabin, it won’t get rid of the noise, but it’ll make it a lot less noticeable when you’re driving. I've heard of a few folks doing this with some success. Or probably just putting on your usual music every time you drive.

Yeah, that whine is super common with the Etorque system, it’s just the generator doing its thing to keep the battery charged. My dealership gave me the same explanation, and while it’s not the worst sound ever, you’d think a truck in this price range would be a bit quieter. I’ve gotten used to it, but it still catches me off guard when I’m not paying attention. If it’s driving you crazy, maybe try getting a second opinion, but from what I’ve seen, it’s just ‘normal.

That noise is something a lot of us with the Etorque system have. It’s most prominent when the system is generating power to charge the battery, particularly at lower RPMs. Your dealership is correct—it’s a normal part of how the mild hybrid system works. It’s not likely to cause any issues down the road. If it’s really bothering you, maybe explore sound-dampening solutions or even get a second opinion just to put your mind at ease. Or there might be a fix through the dealer.

I am having the same type of problem with the noise in my 2021 Ram 1500 eTorque, BUT what is concerning me is that I have been watching my main battery volts on my dash and when I first start my truck with that crazy sounding noise my volts are at 14.5 as I am driving the volts start dropping. My home is about 35 miles from my work and by the time I get home my volts are around 14.0. I have had my main battery checked, and it shows that it is good. This eTorque thing is making me crazy….
