Vibration at 1500-2000 RPM

[liq001]

Hello guys. I just got my 2022 ram 1500 limited with 3.92 rear end and hemi with etourqe. I only put 80 miles on it. The truck is nice in and out, but the only concern is the slightly vibration from the gas pedal, floor and steering wheel. Ift is more noticable at 4WD auto. It is slightly better if I use 2WD. It feels like putting a vibrating phone under your foot. Is this normal for this truck? Thanks for help. It’s very annoying.

Bet you a buck your tires/wheels are out of balance. Also if you have snow or ice built up on or in the wheel that will vibrate them a bit. Take to a tire shop and have them balanced. Or dealer too I guess since it’s so new

If it switches into eco mode while driving that could also give you a sense of a tiny vibration. Does the green eco light turn on the same time you feel it?

There is no snow at all. I don’t think it is the tires/wheel balanced issue. It is more likely from the drivetrain and hemi. I do see the green eco on sometime. But it doesn’t help even if I use tow/haul or limit the gears. From my understanding, tow/haul mods will disable the MDS.

Yep the tow mode would disable it or you can disable it manually without the tow mode. Weird that you get the vibrations. What speeds/rpm’s?

I don’t think it is speed related, it is RPM related. It happens around 1500~ 2000 RMP

Regardless the speed, but the rpm’s around 1500 -2000. 4WD auto even worse.

How to manually disable without tow mode? Is it hiding somewhere in the Uconnect?

No. When in gear and not moving use the -/+ button on the right side of the steering wheel. I usually tap - once then ‘+’ 8x until you see 8 on the display (lower right of screen). You have to do it every time you start truck and need to be in drive but not moving. I guess you can be crawling but in 1st gear. That disables eco mode. All 8 cylinders fire all the time and seems to smooth out the engine. I notice no difference in fuel economy

What is the issue of happening around 62 mph?

Does any one have 2022 ram 1500 5.7 hemi etorque? Need help on this vibration thing.

This has been reported often in the past with the Ecodiesel. My '20 EcoD has the same issue at those RPM's. It feels like a buzz in the gas pedal and wheel and there is slight increased motor noise. Pretty common from what I've deduced by reading about it here.

Is this a ‘common’ issue for hemi too? You are right, it feels like a buzz in the gas pedal and floor and wheel. Is there a fix or TSB related now. It’s very annoying for an 80K truck.

Does any body here have this issue fixed on your 2022 Ram? Thx

Have you contacted your dealer?

Just a guess, maybe the Active-Tuned Mass Modules (ATMM), attached the frame, I believe in the area under the feet?
I think there are two of them, maybe one is bad?

They said it normal. I don't believe them

So you don't have this issue at all on your truck? If it is becasue of the ATMM, why it's more noticeable at 4WD auto? My digital rearview camera keep restart and black out itself. so......annoying..

You’re not supposed to be engaging 4wd auto in dry roads. Yes you will experience some more feedback since you’re engaging your front diff and partially engaging you’re tcase

It’s hard to tell what “vibration” you’re feeling in 2wd

Best bet is to take the tech on a ride with you, and test drive another truck.

Thanks so much. I got it now, I just wondering why it only heppens at 1500~2000 rpms. The feeling is like put a vibrating phone under my foot.
