Sonata I45 (LF 2015+) :: High Rev Engine Noise / Raspy Sound Coming From The Motor
Jan 20, 2016
Been driving my Sonata 2015 2.0t for about 14 months, now. Just turned 13.5k miles. I had first noticed this issue a few months into having the car, but didn't think anything of it. At the time, I wasn't spending much time in the upper end of the rev range. Today, I finally decided that it bugs me enough to investigate.
At WOT, starting around 5500 rpm and going until redline, there is a "raspy" sound coming from the motor that I think might be predetonation, but I'm not sure. It isn't very loud, which is why I originally ignored it, but it is easily noticeable inside the car. I've made some modifications in the past few weeks (Intake, OCC, and Exhaust) so I'm starting to have a bit more fun with the car and want to make sure I get this resolved before it becomes a bigger issue.
Out of curiosity, I looked inside the catch can and noticed a couple drops of fluid (lighter in color), which was surprising since I only installed it ~50 miles ago. Any by "a couple drops" I mean maybe 3mL of fluid. Not sure if that is significant in this case, but I figured it is worth mentioning.
I'm wondering if it could just be the altitude (Denver, CO) and the stock tune is off just a bit? I've been looking into the Lap3 Uncle Chip and HKS performance plugs, but am hesitant to go any further without better understanding what might be happening.

I have a 2015 Sonata 2.0T limited, and there is a noise coming from the back, driver's side, after shutting off the motor. I've taken it in 3 times for this, and each time they say nothing is wrong; but, I've driven a lot of cars and trucks, and I've never heard a noise like this.
I'm guessing it's some kind of gas tank related valve that's closing, but it's making a very loud noise each time.

The last time I had my car serviced, the mechanic told me that while it wasn't a pressing issue, my power steering pump was starting to go. Lo and behold, it's that time. I started to notice that while idling I hear a dry, raspy sound coming from the engine. I left the car on, opened the hood, and it's definitely something spun by the belt. I'm 99% sure it's the power steering pump, so I'm going to replace it. Furthermore, do I need to "bleed" the lines? How does one go about doing that, anyhow?

I cant recall if these sounds were there when i first bought the car, probably because i have the radio on most times. I think the buzzing sounds were present in the last month at least.
After i start up my car and even after idling for a while, i hear a buzzing sound coming from the engine. It gets louder when I accelerate. When I let go of the gas, the buzzing sound lags for a few seconds and then quiets down a little bit, but still can hear it in the background.
I lifted the hood up to listen more closely. I am not totally sure, but i think i can also hear a faint hissing sound ( sounds like leaking air?). I cant pinpoint where it is, but its around the engine.
I also notice that when I am idle, the MPG number in the dashboard is dropping fairly quickly. Like 0.1 mpg every 20 seconds. This is new and started today. I last drove it 4 days ago and didn't notice it happening then and i watch the mpg very closely every time i drive. Could there possibly be some gas leak?

I've noticed lately, that when I do some spirited driving, my rcf is making this weird raspy type ticking noise from around 2500 rpm to 4000 rpm. It definitely doesn't sound normal...
When I take my car in for body repair next week, I plan on having the dealership change the breaks according to the TSB issued and also checking out this noise.

I am a proud and recent owner of a 2015 Sonata Sport 2.0T!
Car looks amazing and am very happy with it.
But lately I have been noticing lots of drone noise coming from the engine, and a really loud cold start as well. The "cold start loudness" goes away after a little bit of driving.
Was wondering if this is just the way the 2.0T sounds, or should i get it checked?

According to the manual the high pitch sound is to let driver know that the pads are worn out but i checked and my pad still very thick after 15k miles.?

Well I've just noticed something quite annoying today... a very slight hissing sound coming from under the rear end of the car. A friend I drove to work this morning even said "what's that noise?".... It reminds me of the sound you'll hear when there is a pinhole in a joint weld, or a clamp is loose? My car only has 2800km on it!

Faint humming/whistling noise coming from the drivings side of the motor. I can hear it when I put my head next to the drivers wheel well, and most certainly from that side of the motor when the hood is popped. It's not super loud, but it is noticeable. I know we have Direct injection motors, so I know that ticking is completely normal. Am I overlooking this and being paranoid? Car has 2100 miles on it. I don't know if it was there when brand new.

I have been little irritated with my noisy/rattling sound ride coming from passenger dash, my steering wheel area and some time front passenger belt. I have taken it to dealership and they could not hear anything so they duplicate the problem and no cation was taken. But they found out passenger side ball joint was loose , so they replaced that under warranty.
I wanna know if everyone sonata makes that noise when you go over little bumps on road, rail track crossing ? it just irritates me too much,,how ever the rattle/noise is not much, i cant hear if i have music on.
Yesterday I tapped on passenger side dash and there was a after tapping noise, like vibration. I don't know if its loose plastic or what. I am not able to detect the exact location where the noise coming from. but i am sure one noise is coming from steering wheel on every tiny bumps.
I want to fix it by myself now, cause sometimes noise is there and sometime not. Is there any way to detect the noise ? Noise- more like plastic noise, like loose plastic, hinges squeaking sound, rattling sound.

With only 1,800 miles on my 2016 Sonata Limited, the brakes make a high-pitched noise when applied and backing up. I noticed yesterday the noise has also started as I brake for red lights.

So i am looking to buy a 2007 Sonata 4 cylinder with 145K miles. There is a ticking noise coming from the motor. Sounds like a lifter tick. You can here it all the time even after its warmed up. I just don't know much about these cars.

I bought my 2006 Sonata with the 2.4L when it had 115,000 and it currently has 130,000 on it now. Ever since I bought it I noticed it had a ticking noise coming from the motor, it makes the noise constantly, it doesn't matter if the motor is hot or cold. I've always been a little worried about the noise. The car does runs like it should though. What it could be?

Eco model (1.6T/DCT). driven 17k miles.
My biggest concerns seem to be the DCT transmission. It's....rough to say the least. It jerks and makes terrible noises in parking lots, which can be quite embarrassing if someone else is in the car. Just today, someone said "is your car okay?" I understand that DCT's are different, but I have driven this car since brand new, and it was never this bad.
The car also seems to shift to a gear that is too high for the speed, making the engine vibrate and sound strained while cruising. This problem occurs around 1500 RPM with the gas pedal pressed and just driving along. I can easily reproduce the issue by putting the car in manual mode, selecting the highest gear possible and then trying to accelerate without hitting the kick-down on the accelerator.
I use synthetic oil from the dealer, changed the air filter already, did the fuel injector cleaner additive and also use ethanol free gas.

When I shut the car off and just sit in the car, I hear a very odd tapping noise coming from the dash to the left of the steering wheel. It taps 3-4 times, stops for 20 seconds, and taps again 3-4 times. This process repeats a few times and then stops completely. What on earth could it be? I'm thinking its a bad relay or perhaps the car is possessed. I'm not sure I could reproduce for the dealer.

I just bought my brand new 2015 Hyundai Sonata 2.4L SE 3 weeks ago and have put 4000kms on it so far and from last week I am getting a rattling noise from just behind my steering wheel while going over washboard surfaces every time. Feels like something plasticy is loose around the upper steering column which rattles every time I go over a washboard surface. My university campus has a lot of rumble strips to slow cars down and that is where I noticed this noise very clearly.
I have taken my car to the local dealer and the mechanic there have acknowledged the problem after comparing the noise with a new car there. He tightened some bolts around the lower steering rack apparently but the problem is still there. He says to bring the car in after the problems gets significantly worse because it is still not severe enough for him to diagnose it and find what is causing it. I do not know much severe I need to the let the problem get before they do something about it. The dealership still has the ticket open for me; I will probably try to visit them next week again.
This thread more or less describes the problem I am having : Steering wheel noise over bump .....

Experiencing a metallic click or something alike when coming to a full stop?
I've notice this new noise and it seems to happen about 0.5 seconds after the car has come to a complete stop, not during the stopping. It only happens when stopping at a red light, and it doesn't do it on stop and go traffic.
It also doesn't seem to coincide precisely with applying the brakes because is AFTER the car has stopped, again, in less than a second. I hope that makes any sense.
It happens maybe 25% of the time but, then again, if I go to the dealership I'll probably won't be able to reproduce it.

Car has been running rough for a few days. Last night my engine light came on p0017. Called the dealer and they couldn't get it in until Monday. They said if the light wasn't flashing just bring it in then. So I disconnected the battery for a few minutes and the car started much smoother and the light went off. Drove into the city and once I got to my destination the light came back on and the car was running rough again. Decided to finish up and head home. However once I got in to make the drive home I could now hear a rattle when I accelerated coming from the engine. Then the oil light would come on every time I hit the gas to accelerate. I made it home as slow as possible but when I checked the oil it's not even reading on the dip stick and the dip stick smells burnt. No oil on the floor, oil filter and plug shows no leaks. I have noticed the past few weeks that my exhaust tips are dirtier than usual and black drops were all over the rear bumper and back of the trunk. Could this thing really have blown out that much oil. I just changed the oil less tHan 1000 miles ago.

2016 LTD Ultimate, 2700 miles. First and only Hyundai for the moment.
I've experience this one twice, a few weeks apart: cold start the car, and in the first 100 yards or so I'll hear a tapping noise that's clearly rotational, varies with speed but eventually ceases. Sounds like it's coming from front passenger wheel well area, and sounds like a stick or some sort of debris is stuck in the wheel. Both times I've inspected the area and found nothing whatsoever.
I live in an apartment complex area, park in a lot always in reverse so I'm always going from park to drive. The area I live in is wooded ("Pine Barrens" region of Long Island) but the roads are paved so it's not like I'm driving thru wilderness.

I ask this because when on the hwy (60-70mph) you can feel some vibration in your hands. I can let the steering wheel go and it won't move a bit but when hands placed on it you can definitely feel the road, including bumps, and regardless of road conditions. Tires where balanced at 7500mi but it still happens. Regardless of temperature or PSI in the tire.
I thought we had electric/electronic steering and no hydraulics? Maybe unrelated but, when turning in my driveway, very slow, I can hear a slight clicking (maybe rubbing) noise coming from the steering wheel column. Everything else has to be silent to be able to hear it.

Just bought my first Ford. Its a 2015 F250 Platinum. Im at 1400 miles and Im becoming concerned because when I start the truck for the first time in the day, no matter how long I let it sit and warm up I am noticing that on the first couple of miles of driving I hear a high revving sound as I accelerate and it seems to quick shift during those first few miles.
As I continue to drive the high rev sound just fades away and all engine sounds and shifting are as normal as can be and will remain that way until the truck has been sitting for an extended period of time and is cold. I thought it had something to do with tranny temp but this morning I let the tranny warm up to about 115 deg in neutral before taking off but still had the high rev for the first few miles. I have never owned a ford nor have I ever owned a heavy duty truck, hoping this is normal.
