I have this vibration when in Eco mode too. Does Tow mode turn MDS off?

I've had this from day one.....at around that rpm range....yes tow/haul will eliminate it because the shift point mapping changes...

I'm sorry to hear of the trouble you are experiencing, raven_DT. If you plan to address this with your dealer again, please let us know via private message. We would be more than happy to provide you with an additional layer of support for that process.

Similar problem at 1300- 1500 rpm but mine does it from 10 to 70 mph intermittent and recurring. Just started at 4200 miles. Also noted the tachometer is now very jumpy from 1500- 2000. Tow/haul function on does not seem to improve it. Heading to dealer today. Ram Tradesman 1500, 4x4 5.7 Hemi

Mine in shop as I write this. Back in October, finally got it to 'drone' on the service manager's staff, after filing 'Lemon Law' complaint since I've had the truck back to the dealership over 6 times since April. Dealer reflashed ANC and changed the noise from a 300h buzz to a 90-100 hz drone that sounds like a center carrier bearing has failed (doesn't have one). But wait...now we are replacing headliner, right curtain air bag, steering wheel, windshield...all because of service tech neglect. Started with headliner being damaged in Michigan where the vehicle was assembled, now...several months later, by dealer. At last visit the service department dragged something across the steering wheel scratching the leather, left windshield whistling at 60 mph, left sun visor hanging 3" from the ceiling, one of the right side mic's dangling from the headliner, poked a hole in the air curtain and they called it good...that and in changing the oil, spilling oil all over the engine...and just leaving it. I'm ready to go back to Ford....

Ive experienced this same issue with mine very noticeable in town driving when eco mode engages i feel the vibration in the steering wheel and pedals sounds like a bad wheel bearing. I took it into my local Ram dealer 4 times the did a reflash of the anc and then tried to say its making noise due to a aftermarket mopar exhaust which i looked up and it does not have one its just a normal factory exhaust. The last time i took it there they had it for 2 days and said they cant duplicate the complaint which is bs . I work at a dealership and have compared it to other Ram 1500 same year and engine specs and they drive smooth in and out of eco mode. Very frustrating on a new expensive truck.

Has anyone come across a fix for the issue yet?

I found the issue with droning just below 1500 RPMs while in the MDS/Eco mode/ANC and particularly noticeable when I had occupants in the rear passenger area or the back seat was loaded with tools and gear. I brought it to the dealership with the back seat loaded and they performed TSB 23-023-19 and all is good. Hope to have better luck than raven DT in post 4.

I have not had my truck updated but do experience it occasionally, luckily it has not been very bad when it does happen.
The one true way to get rid of it is to search on this forum for how to disconnect the anc mics, that disables the anc system completely.
I may do it at some point but we'll see when that happens...I also have some sound deadening to install in the back of the truck but that will require a full day to work on

Do you have a copy of this TSB? I’ve searched high and low and can not find it.

A simple fix for this is use the gear selector, and place it in 8th gear. The truck will shift normally and eco mode (MDS) will not engage. The vibration and drone is a normal characteristic of eco mode
The ANC is a whole problem in itself. Mine has been bypassed using a harness from Crutchfield. Use Google to search this forum, the built in search function is terrible

Will try that. Have a new 2020 Ram 1500 Classic Night Edition. Previous Ram wasn’t dual exhaust (2017 ST Classic) and it was fine. Its minor but annoying. Like shifting a manual too early. It’s like they are trying to hard to save a bit of gas.

My truck engine has been rattling since day one in eco, specially on cold starts or accelerating!
Just kidding everybody, my truck is always on eco, meaning eco diesel .
On my 2011 Ram with the Hemi, I do recall the different tone of the engine when it switched from eco to 8 cylinder modes, the transition was seamless as far of transmission performance but the engine sound was definitely noticeable.
