intermittent humming noise and vibration

[RamCares]

Well I just joined the club. Traded my 2016 big horn which I loved and had zero issues with in on a 2019 ram bighorn blacked out package one week ago. we have three rams in this household (daughter, son and myself) the 2019 may look nice but overall the 16 and 17 so far seem to be better trucks. I have 200 miles on my new 2019 and it vibrates horrible at between 1200 -1500 rpm seems more prominent when lugging like its in too high gear for rpm and the exhaust is rubbing causing a pulsating buzz. Sounds like an airplane is flying over the top of you and vibrates the cab and steering wheel. Actually hurts the ears it gets so bad. I will be calling the dealer in the morning but looks like fix might be a fight to get done. Fuel mileage is much worse than my 2016 as well. Seams they cheapened the trucks and raised the price very disappointing hopefully the dealer will stand behind it we’ll see

Hi Kesh,

Keep us updated on what you hear from the dealer. Our team is available via private message and can help with that process.

I started hearing this tonight. My certified 2019 Ram 1500 with 15k miles on it. I did a search like most of you and came to this site. I'm taking to the dealership tomorrow. I traded in a 2014 Ram. Should have kept it.

I was annoyed for a good bit but given lots of good advice here and a dose of patience I have been enjoying my Ram despite these nagging problems. It is important to note my service experiences have been, if not perfect, at least positive from the standpoint that my service techs don’t give up and continue working a problem until it is truly fixed. Unfortunately this is not the case in many shops. Good luck, I hope your humming problem gets fixed with the 30 minute flash that mine needed.

Just bought my '19 Bighorn 2wd (less than 500 mi.). Love everything about it except the ANC, which is already irritating me with it's deep intermittent loud hums. Knew what the problem was immediately because ANC was listed on my window sticker, (had a Honda Pilot previously that had it and it malfunctioned constantly with the same low hums) and was a little concerned. Didn't hear it during the test drive, but did on the way home. I'd just like to verify the TSB number so I can take it back to my dealer and have it fixed, or turned off completely till they can.

Looks like you saw this, it is the correct TSB number:

#08-033-19 I think, I added a post to our TSB thread in another section of the site.

I started hearing this yesterday too, and noticed this morning that the ANC seemed to stop working, road and wind noise was much more noticeable than before. Thanks for posting the TSB, now my trip to the dealer will be much quicker.

How long does it take to do the update?

 

[Jzelbst]

I need to take mine in to get this update. It gets annoying and is pretty embarrassing being that the truck is new

 

[YoAdrian]

Once they start prob 30 minutes? It’s just a software update for an easily accessible part.

I have the exact same issue happening. Feels like it is growling and binding, restart does not make it behave. Dealers have a month or more wait,WTH

Would love to see what they come up with yours. Leased my 2019 Bighorn Hemi back in Sept and this same issue started about a month in. Now at 9,000 miles and it continues. In for service twice, audio update applied, in for recall on May 7th, Chysler customer care called months ago, a case still active and open. Laughed out of one dealership and the dealership i bought it from is a joke. Like how can this award winning truck be a lemon? Well it is! If this recall doesn't fix this problem I will be getting a new lease! Or a new brand.

I have also experiance the same noise, to me it almost has a similar sound to engine breaking. I have had it a few times. Planning on taking it to the dealer. The other thing I notice is the hum or sluggish sound at each gear between 1200 and 1500 rpm. Again it feels as if I was drive a manual and shift to early and get Stutter vibration until the rpms pick up. Super annoying maintaining the speed limit because you just feathering the gas to maintain speed resulting in low rpms. Now if I'm actively accelerating this noise never occurs. It's like the truck doesnt shift at the right time and is always a gear high maybe.

Sounds like cylinder deactivation and MDS kicking in. Not necessarily a problem but more of a feature?

Regarding my 2019 RAM 1500, new in Dec. 2018.
The above is what my dealer thought when I took the truck in. I didn't notice this very loud humming until I drove from North Carolina to Florida in December. It was cold (17) in North Carolina, much warmer in florida (upper 60-70s) and that's when I started noticing the hum. For me, it happens at around 50mph unless there's someone in the back seat. If there's a backseat passenger, it is frequent, loud and happens at any speed. If it's just me in the truck, it happens at around 50mph, lasts several seconds, goes away and comes back after about 20 seconds. If I increase the speed to 52mph it goes away. I had to go back to North Carolina for a couple of weeks and took it to the dealer where I bought it. Again, it was cold there, and the hum couldn't be reproduced. The dealer tech took it out with the computer attached and found no problems.
I think it's got something to do with the exhaust resonating. The hum is always the same tone, no matter at what speed it happens. I'm back in florida, and have noticed a definite correlation with the outdoor temp and whether or not the hum occurs. The higher the temp outside, the more frequent the hum. This is a very frustrating problem. I love everything about the truck except for this hum.

Correlation isn’t always causation... but it might be. Need to test to confirm if its exhaust or ANC. That sure behaves like the ANC problem though, as the back seat passengers affect the microphones. Same thing happened to me. TSB last week fixed it.

Next time you hear it test if it is tied to your rpm vs speed. Downshift at a constant speed to raise the rpm, see if it changes. Roll down the window 2-3” see if it goes away, and roll em up see if it comes back. That’s also ANC.

Purchased mine (2019 RAM Lonestar quad 5.7l no e-torque 3.21 2wd) 4/9/19. Over the last couple of days, loaded back seat with 30 lbs of dog-in-a-box, 25lb cooler, 50 lbs or so of luggage, 300 lbs in the bed and going up my 30% grade driveway the noise was AWFUL! I honestly thought I had backed over something and pretzeled the exhaust into the bottom of the bed. After inspection and finding nothing, took off enjoying my fillings being jarred loose by the droning. After arriving at destination, called Texas Dodge where I purchased this truck, spoke with service advisor who was alarmed and told me not to drive it....I told him there didn't appear to be a 'mechanical' issue, and I would see him Monday morning. Because of this forum, I have LOTS of ammo.

On a side note, I traded a 2015 F150 XLT Screw 2.7EB that made about five too many trips to the dealer to fix an oil pan leak.

Guys TSB 08-033-19 software flash worked for me too no more humming noise at ALL!! please take this to the dealer and tell them to perform the flash! they will want to replace your ANC unit but NO NEED! they flash fixes it I'm 100% sure! or at least mine got fixed!

I'll post the notes that they had for my repair later today!

 

[Doughie1]

This noise every is experiencing is the active noise cancellation messing up, my truck did it today for the first time after 20,000 km, it's coming through the stereo, my speed warning is interrupted by it. If I cycle my ignition it goes away.

 

[wildh24]

Mines going in today to have it applied.

 

[wildh24]

So had one of those days at the dealer. Took 30 min to drop off because the service guys were in a meeting. I had already called in and gave them the TSB but the asked what was song to I explained it again. They sent it back and call at the end of the day for me to pick it up.

I get there and they say everything was already up to date and the couldn't touch anything because the factory sub was unhooked and I had installed an after market sub. I went back and forth but the guy threw up his hands. IMHO, the aftermarket sub had NOTHING to do with it.

Got in the vehicle and sure enough, the drone was still there. So pulled over and unhooked the ANC connection under the seat and drove. Drone gone. Plugged it back in, drove, drone back. Obviously they did nothing. So I pulled over again and depinned the 3 and 4 mics. Drone gone.

I'll leave it like that because I honestly couldn't really tell if ANC was actually doing anything. If anything it reduces the muffler noise a touch, but I could really tell any other difference.

Sheesh. TSB software squirt to a known problematic system, takes 10 mins and no parts. Where’s that service department so I can avoid them? Bet you could fight it but if you can find happiness then good enough!

Tell me about it. I wasted a solid hour today. They're usually decent but today it was annoying. If they just would have called me when they were looking at it, I could have explained but nada.
