Excessive Road Noise? Howling/humming sound

Maybe a bulge in your tire or an out of round tire?
This could do everything described, all by itself. I had an out of round tire on my Voyager for over a year and put up with it. When I got four new tires it was like a different vehicle, night and day. The out of round tire worked for its life. But it vibrated, pulled and was noisy. I couldn't push over 70 MPH or it felt like it was trying to shake the steering wheel out of my hands. Super annoying. I adapted and drove slower and decided old vans just do this. :P You see, I had no idea it was anything as simple as changing tires: didn't want to spend money on new tires until the tread was shot; and wasn't sure if it was a tire problem or something to do with the suspension; balancing and alignment didn't solve a thing, obviously, and I gave up trying to figure out was was causing the vibration pulling and noise: figured that if it wasn't an alignment or balancing issue, it must be something a lot more expensive, and I didn't have the money to pursue it.
 
Now that I have almost 6000 miles on the car I wanted to give an update for the symptoms my car has to see if more info might help someone come up with the root cause of this issue. Especially since kia still says there is nothing wrong. Updated symptoms for me include:

1. The really loud howling noise now happens between 30-33mph and 60-63 mph. It's so loud now that I can play slipknot with the radio set on 40 and still hear it. This noise is made even louder with colder air temperature and/or by a heavy downpour. Snow melt on the roads doesn't affect it, just if it's pouring rain.
2. A quieter version of the same noise happens now from 10-90mph, just gets really loud at the speeds I mentioned above.
3. There is a wobbling noise that happens from 58-60 mph.
4. At speeds between 10-20mph there is a sound that sounds like rubbing/grinding, but that goes away above those speeds.
4. The car pulls to the left if you let go of the steering wheel despite having an alignment done and having the tires rotated twice in 6000 miles.
5. Upon cold start there is a pogo like effect from the front suspension until the car reaches about 40mph and the brakes are applied. Then it doesn't come back unless I let it sit for a few hours.
6. At a speed somewhere between 80-90mph the entire car starts shaking.

If anyone has any theories I would really appreciate it. I honestly don't know how to force kia to actually fix the issue, so I'm hoping someone might have an idea of what might be causing this stuff so I can ask them to look at a specific part.

Preciate you checking in, since I was actually just about to bump this thread with my current situation. I am also running all-stock configuration, with RWD 19" staggered Michelin Pilot Sport 4s.

Dealership replaced my front suspension units and the noise still persisted, so I'm thinking (at least for me) that the noise is hopefully only tire/wheel related. I have around 7k miles on the car and I will attempt to compare my experiences with yours as of late.

1. The major noise range for me is basically the same (~30 mph and ~60 mph). I've determined that the noise really varies based on the road surfaces I'm driving on. Down in Texas (where the roads are horrible), on some roads I can literally hear my car howling to the point where I play music at the 30-40 range and still hear the noise, and on others the noise essentially dissipates and I only hear it occasionally on road irregularities. Like you, the noise in my car gets louder when its colder outside or when the roads are wet.
2. I can immediately start to hear it when I go 5-15 mph and when I get to standard traffic speeds it gets more intense.
3. I do not believe I've experienced that type of noise. Is it frequent? If you can post a video of it that would be very helpful.
4. I have not experienced this issue.
4b: My car tends to pull both ways but more frequently to the right. I have not gotten an alignment done yet and I've had my tires balanced once by discount tires (they said they do road balancing but not sure if that's accurate).
5 and 6. Don't believe I've experienced this. My car shakes left-to-right when braking but only a little bit and I think that's more due to the brakes. My steering wheel is a bit sensitive when I hit 80+ but my car is still stable.


With all that said, if KIA is giving you the runaround, try calling the VIP line. Not sure if it's effective for certain and you'll probably have to put up some resistance, but from what I've heard they can get the dealerships to act.

I plan on getting a proper alignment check and balancing done at a reputable shop specializing in such services. If the noise still persists I'll return to the dealership and escalate the issue. I'll be sure to report back with their diagnosis and results.

Not Hwy 287, by any chance? I simply turned my music OFF on some parts of that road, it was so insanely loud.

Nah south of that. And it's crazy - One second I'll hear the "blow over the bottle" noise at max volume and then I'll hit a different patch of pavement and the noise basically disappears. It really baffles me.
 
Glad you reported back, I was going to follow up on this thread to see how things are going for you. I put my 19" wheels and all seasons back on a few weeks ago and I notice the tire noise much more again than I did with the 18" wheels and snow tires. That said, I haven't experienced the other issues you're experiencing...although I only have 1800 miles on the car.

As has been said later in this thread, this car is amazing and I've thought about what could replace it at this price point and there isn't much that could touch it as far as features and performance is concerned. I've basically come to the fact that I'll have to deal with this annoyance as everything else about the car is great. Keep us in the loop with any more info or findings you may have.

Do you mind sharing what 18" wheels you are running? I might go that route and sell the 19's if it's a sure-fire way to reduce the noise issue.

If these noise issues are really due to hypersensitivity, I'm willing to give up some performance for more comfort.

Thanks. I'll see if I can get my dealership to swap out one of their sets to see if it helps any. Also to add some additional observations:

- The noise persists throughout most of my drive, but as previously stated the noise is acceptable and very miniscule on certain road services I drive on.
- My steering wheel resonates 'in-tandem' with the noise. I can usually feel the bumps/resonance of the noise through the steering wheel, and as the noise gets more intense the resonance increases as well.
- Still get the same noise in more of a "boing" manner through my front tires only whenever I go over sharp speedbumps.
The noise is usually louder when I am turning or driving on an incline/decline.

That's definitely the exact same noise and symptoms I have too, although I don't have any steering wheel related issues...it's just noise.
 
The car pulls to the left if you let go of the steering wheel despite having an alignment done and having the tires rotated twice in 6000 miles.
I had my car in for a wheel alignment as mine too suddenly started to pull to the left for no reason. After the independent alignment it was still the same.

The shop owner suggested it was a known problem where by Kia should just simply reset the steering by going into the settings. Kia did just that after the garage owner rang the Local Kia service department. That cost me nothing issue solved.
 
Just to add my 2c worth.
I’m in the U.K. and have a 2019 GT 3.3
I get the same noise from the front right on mine and have done for pretty much the entire life of the car so far.
its been to the dealer a few times who can’t find anything and now I just live with it. They even had it for 4 days to strip the dash out to the bulk head and reassemble.
To me it does sound like a wheel bearing / hollow resonance sound that you can get as low as 20Mph and as high as 140 (autobahn).
I also agree with what has been said about the wheel balancing and alignment, it took 3 goes and 2 shops to get it worked out and running well.

did you call kia service to fix steering pulling to left? i dint understand “kia should just simply reset the steering by going into settings”

The independent tyre and suspension place suggest i take it back to Kia to get a "Steering reset". He actually rang the sales manager and explained it to him.

Latest report: steering and alignment back to good old normal pulling to the left..damn. (RHD). Lowering of the car is said to blame for the issue.

oh, my GT1 is pulling just slightly to left, currently i’m at 2k miles. i noticed that rear wheels got 41psi, i will try lowering it out and see if that solves.
 
I also have the same issue....I have a 2020 Stinger Gt......It sounds like the noise when a rear window is down and the vibration kills your ears! I thought it was the tires at first, but after getting on this website it is clearly a KIA problem! Very disappointed. I want to love this car, but the noise is a deal breaker and probably will end up trading it in.
 
I've had my stinger for about two weeks now (brand new) and I can't help but notice in the past week or so there is a howling or humming sound coming from what sounds to be the front left wheel area or somewhere around there. To me the sound is similar to blowing over an open bottle. The sound is present over the typical road noise that we should expect. Could this be a tire, wheel alignment or something else? The noise doesn't really change pitch or get any louder dependent on speed so I doubt it would be a wheel bearing especially since the car only has 650 miles on it. I can produce the sound from about 20-80+ mph and it doesn't seem to make too much of a difference what kind of road surface I'm on. I've put it in neutral and coasted and the sound is still there. No change in sound when using different drive modes, turning off engine enhancement sounds or that either.

I'll probably take it into the dealer but was just reaching out to see if anyone has dealt with something similar to this before and if they were able to track it down and resolve it. It definitely isn't something I'd consider a normal sound and I test drove a few other Stingers before purchasing mine and don't recall hearing this noise. Sorry if the description is vague haha. Such an amazing car but this is definitely a slight annoyance...
Same issue!!! I just don’t understand

It's coming from the exhaust in rear in the trunk area. Sound deadner in the bottom of the trunk and under the back seat works

I had a rim repaired, tire checked(checked out just fine), fender liner replaced, had my hub bearing(s) checked. The tech said that it was just road noise. So I scheduled another appointment because it is an unsettling feeling when you know/can feel(or in our case, hear something isn’t right) something is off and causing this noise. After seeing some of the pictures in this particular thread, I checked all of the panels underneath and everything seems snug, what I did notice is that I’m missing one plastics rivet right behind my right front wheel right before the brake vent/duct. Being that they road tested it and diagnosed it as “road noise” I wonder if I went to an auto part store and purchased a rivet would that potentially stop the low tone humming at above say 45 MPH
 
^^^I'd replace any missing rivet/fastener just as policy. If that fixed an annoying extraneous noise so much the better. :thumbup:

Being that I have had it troubleshot for the usual suspects, maybe, just maybe the right amount of wind in getting through the hole and causing it…..if not it’s going back in anyway for alignment, oil change, rotate and balance.
 
Alright, here we go. A month and a half ago I took Dirty Red in to the dealership as soon as I noticed the fender liner was visibly damaged. I replaced the tire that was damaged on the whole opposite side due to a pothole. You know, responsible adult ****. I take my car in like I said for some very very faint vibrations, and the damaged fender liner. The dealer then kept my car overnight because they wanted to ensure that there wasn’t any mechanical damage to the front suspension. They called me the next day and stated the obvious, there is damage to the fender liner, cool, I saw it, I was the one who originally pointed it out, I will pay to have it replaced at the dealer. No big deal. Then my Service Advisor states, the vibration you’re feeling is from a bent rim. At that time the Service Advisor stated that rims were on backorder, again, no big deal as he pointed me in the direction of a local business that they use for things like this and they’re pretty good. I asked was there any other damage that I should be aware of, he said no. All of the wheel and suspension components were just fine. Asked me if my insurance would be paying for any of this, to which I stated why would they, I got this. So I had him order the fender liner and call me when it came in. Two days later, it’s in, they replaced it, I paid $240.00 and it was a done deal. Next order of business is repairing my rim. The company they sent me to had a rim in stock, rim replaced. Good to go. I start noticing the low humming coming from the front during certain speeds. I took my car directly to the dealer the next morning, before they even opened. Once opened I explained the symptoms, he asked if I could leave it because the actual tech is behind from the day before, I said no problem and my daughter comes and gets me and takes me to work, which is roughly 45 minutes in the next town over. I go into my office and within 20 minutes of being there the Service Advisor calls me and tells me that the Service Tech stated that the noise I heard was just road noise and I can come pick it up. He stated the tires are good, suspension is good, etc…. So after researching here and on the interwebs I asked if they checked the hub bearings, at least a good 10-15 seconds of silence on his end, so long in fact I asked if he was still there. He then said that they did, but if I wanted to be sure that they can set me up with an appointment on the 16th of May at 8 a.m. and I can have a Tech ride with me so he can hear the noise. So the 16th comes and I am pumped because I want my damn car fixed, I arrive at 7:15 a.m. and meet with the advisor who set the appointment, he said the Tech is two cars behind but he assured me that they would get to my car no later than the afternoon, Tuesday(today) morning at the utmost latest. I relent, and go to work, on my way I call and ask “since it’s there, can I go ahead and get ahead on my maintenance(oil change, replace filter(s), and a alignment, which my car was do for anyway) he says sure, we will make note of oil filter, cabin filter, air filter, turbo filters, alignment, and synthetic oil change(even though my Stinger isn’t high mileage enough, 2019 sitting at 41,000) but I’ll worry about the oil change once I get to that point. So then he proceeds to ask me if my insurance would be covering the cost of repairs? I am like no, why would they, especially if my car hasn’t even been diagnosed yet, and I was like, “you had my car twice and couldn’t and didn’t find any damage, and you stated to me as much” his retort was “well you had a fender liner replaced” and I said “yeah, and? you said that my car was mechanically sound, and you don’t even know what wrong” since they keep pressing me about my insurance I asked “if it turns out to be a hub bearing, is it covered under warranty?” Response: “normally, but we don’t know in this case because you had a fender liner replaced” at that point I feel like they’re trying to set me up for some BS, so I end our discussion and say I look forward to hearing what the actual diagnosis is. So today comes and goes, no call. So the dealer is on my way home from work and I decide to swing by, I drive around the service department and there Dirty Red is, sitting in the same spot I assume it’s been in since yesterday. I go in because I want to see what I’m up against. I go in and the Service Advisor is off today, and my original Service Advisor is apologizing because it’s just been him all day, and he’s behind and he doesn’t have info on my car, but he can look it up. He says that there is Tech assigned to it but hasn’t gotten to it yet because they got behind again, then I’m like is this how appointments work? He apologized and said at the latest they’ll call me tomorrow, and then I said, that’s what they said yesterday. My question, is the point I should get the “big wigs” involved, and if so, who and how? And if not, what would y’all do?

***Edit*** sorry if this was long, but kind of frustrated.
