Loud Rumbling/Revving Noise

[wildh24]

That sucks. I got tired of the run around and just unpinned the #3 mic and I haven't heard it since. The cab still seems as quiet as before.

Could you please provide more info on this? Have you already posted it in this thread? If so, I’ll look for it. Otherwise, I am just kindles burned out on dealing with this...lol thanks man!!

There's a few posts on how to do it on the forum. You can unplug the harness to the module under the drivers seat and if you depin the wires from the mics (only need to do the + or - ones... Don't need to do all 8) it disables the ANC system. I was just experimenting to see if it was caused by one and did just the #3. Seems to have fixed it for me.

Do a forum search for 'disable ANC'. There is a step by step. He's a picture of the wiring harness to help you know which ones to do.

Awesome, man! Very much appreciated!!!

I have the ANC "disconnect" wiring harness I'd sell if anyone still has the noise and wants to disconnect ANC via a plug vs. messing with pins for this reason or for new speakers. The TSB fixed my noise (or as good as it's going to get I guess) a week after the harness came. PM me if interested.

I’m also having the same noise in my ‘19 Bighorn. I have an appt on 23 May. Will keep you updated.

My Ram is still having these issues, had reflash done in April, still moans on coast down and any rear occupants.

Well, after the flash upgrade (they changed shift points so it’s much harder to keep at 1250rpm) and ANC swap, I am having much harder time to reproduce but, still can do. Have phone video recordings but now, the service foreman wants to ride with me and wants to hear first hand... have to find a long downhill where, I can just roll and keep rpm at 1250 for a few seconds. Otherwise, as soon as I step on the brakes, the truck downshifts and rpm goes 2k. A pretty smart work around, I have to give it to Ram...lol!

You can depin the ANC at the harness on the amp. I have a write up on it over at ramforums. It corrected the problem and all systems still work. I can make a thread on it here if others are interested.

Hello all, just joined forum and see folks that have reported the same noise issue that I have had twice now. Made arrangements with my dealer to look at it. I got back from the dealership 7/9/2019 and they told me it was something with the MDS "Multi-Displacement System" and that this noise was normal. My issue with my ‘19 Bighorn is when I started up my truck up the noise was over powering my radio. The radio was only turned up to 8 on the radio volume dial. This noise was over powering the radio. "This defiantly was not bass being to high."I ended up driving for 25 mile to work with my truck making this noise. Noticed to the when letting off the gas pedal the truck did not coast like normal. The truck slowed down a little faster then normal. When I got to the parking lot of my work I wanted to check the brakes so I touched them and they were so hot you could cook an egg on them on all four brakes. I do not ride the brakes when I drive so thought it was strange that they would be so hot. So I feel my dealership is feeding me BS by telling me it is the MDS because they did not hear this noise I was experiencing. The noise is intermittent and only happened 2 times since I owned this truck. My truck only has 7000 miles on it so not even broken into yet. I have the key less start so when you step on brake and push button on dashboard to start the truck I believe this may be a bad sensor that does not disengage the caliper away from the brakes and cause this noise, but also I do not know why it would make this loud noise when starting it in my driveway. However I am not mechanically inclined so I am just throwing this out there on what possibly could be the issue. If anyone has a true fix from there dealer and got this resolved please post it so we all can present it to them. I am nervous because I tow a 5000lb travel trailer and want my family to be safe when going camping..

Thank you for fast response! I will pass it on to the dealership to see what they say.

MDS isn't even on when the truck is idling. It only turns on while driving under light throttle conditions and goes off if any throttle is added. Maybe choose another dealer?

Actually, it doesn’t fix it. Makes it harder to repro, yes but not a complete fix. Mine still happening at 1200 rpms downhill, off throttle. Makes it hard to record bc my phone not picking up 45hz too well.

 

[Rambruiser]

I now have high quality audio of the issue. Had my 10yr old daughter helping me w/ troubleshooting. She actually pointed it out that, the sounds is coming from the rear speakers. I’ll have this uploaded on YouTube by the weekend.

 

[Kylemcmonigle4]

Mine is still doing the long drone sounds even after the dealer had it for 3 days and did absolutely nothing to fix it. It is the worst especially on long road trips. Ram please fix this it is absolutely ridiculous.

Hi,

New to the forum, I have a 2019 Ram that's a week old with 100 miles. Last night I turned the car on and as I put it into drive, there was a terrible loud, low pitched rumbling noise in the truck. I'm talking ear-piercingly loud. At first I thought it was engine related but as I tried to diagnose it sounded like it was coming from the car speakers. Is this an active noise cancellation malfunction? It was almost like it was taking engine noise and amplifying it throughout the entire truck. Turned it on this morning and had no issues. I called the dealer and they suggested I record or call them the next time I hear it.

Anyone heard of this before? It was so loud I literally had ringing in my ears last night and this morning.

I'm also having this problem with my 2019 Ram, it's currently still in the dealer for repair but they can't get the noise to happen again. They did witness/hear it when I originally brought it in, very frustrating. What can we do????

 

[Muskyhunter50]

I'm having the same humming noise with my 2019 Ram, it's currently at the dealership but they can't get it to happen again. Has anyone found a fix for this????
