Sonata I45 (LF 2015+) :: Engine Vibrate And Sound Strained While Cruising
Feb 8, 2016
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.

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?

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.

Upon cranking my 2002 Dodge Grand Caravan and driving app. 10 miles the speedometer and odometer will stop working and the motor will sound strained for the rest of the driving time. The rpm's go up and it dies from time to time when making a quick stop or turn. It starts right back up. The next day upon starting again the process starts all over. What's the problem?

I did a search and what I saw all had to do with noise at startup.Mine is during cruising. I have a 2007 Sonata 4 cylinder with 112K miles. Within the last few months it began making a slight chattering noise when I accelerate and when cruising. It's worst around 55mph. When I let off, it almost goes away, but is loudest when I just am feathering the pedal to maintain speed.
If I put the pedal down a little more and accelerate, it is not loud, but still faintly there. At first I thought it was a tapping sound, but I've let some of my friends listen and its more like a clattering, metal rattling, or vibration perhaps. Its hard to describe. A week ago I had the check engine light come on with a "P0011 Hyundai - 'A' Camshaft Position Timing Over-Advanced Or System Performance Bank 1".
I changed the oil and took it into a local shop and they cleared the code/light and checked things out (the light hasn't reappeared). I had them take off the valve cover and make sure the top end was not making the noise. It seemed fine to them. They suggested I take it to the dealer for further diagnosis. I have not yet. It does not make noise during start up. If I have time I will upload a audio recording later. What may be making the noise? It seemed to get a little louder after the latest oil change, but that's probably me being more sensitive to the problem.

I've had my 2010 Prius for about 3.5 years now and this is the 3rd maybe 4th time happening. This morning I started the car and the car started to vibrate/rattle from the engine bay. It almost sounded like the wheel of fortune being spun but louder.

I've been noticing a metal type 'clanking' sound whenever I am gently accelerating up a hill on my 2.4L.
It doesn't happen all the time though. It's not the usual GDI ticking sound. It can be heard when the windows are open but yet I can not tell where the sound is coming from. It doesn't happen enough that I can replicate it so I haven't taken it in for a check. The car drives fine though.
Sounds when going up a hill? Not sure if it's from the engine or from the transmission getting confused trying to change to the right gear. Perhaps the sound is just normal...

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.?

So I brought the Sonata home and she sat in the garage for 5 days as I was traveling. Then when I got back, I was so eager to take her for a drive. At this point she only had 72 miles on the Odometer. When I started her up, I thought the engine sounded rougher and louder than usual. My other car is a Turbo Diesel and that does not make this loud a clatter. After a few minutes of idling and driving, the engine quietened down quite a bit.
Video of the sound at cold start up.

I have been having a grinding/metallic sound when going up hills in 4th/5th gear. It sounds like if you threw metal into moving parts. I believe it's coming from my engine or transmission. When i was at the dealer last month for a campaign and ecm upgrade i mentioned this problem and they replaced the vcm motor assy, however the problem still exists. What could be causing this problem?

Noticed an intermittent creaking noise when the vehicle is in motion (low to moderate speed). The noise is not very loud but audible if you turn down the radio volume. It sounds like 2 hard objects rubbing against each other. I am positive it comes from the panoramic moonroof because it only happens if the moonroof is close. The noise goes away instantly if I open the moonroof ever so slightly. It has been intermittent and seems to happen at any temperature.

I have a peculiar burbling sound when pressing on the brakes or in park. Sometimes I get in while reversing. It sound like it might be idle related and may have something to do with the exhaust but I am not sure.

I have a 2015 Sonata 2.0t limited with 12k miles. Just few weeks back I started hearing a noise when I would step on the accelerator after a full stop, when the auto hold feature was turned on.
With the auto hold feature off and my foot on the brake, I don't hear that sound when I release the brake. It only happens when the car is stopped and the auto hold is on and i step on the accelerator.
I took it to the dealer and he is saying the brake calipers need to be cleaned up. I'm not convinced it's the brake because I don't hear the sounds when I don't use the auto hold. What can I do to fix this?

When I move the wheel to the left, I get this metal grinding sound (similar to rust on brake rotors/worn down brake pads). It happens when the foot is off the brake and ONLY when the wheel is turned to the left.

When I turn off my car I always get out within 10-20 seconds until today. When I shut it off after a errand I was checking messages on my phone and after about 45 seconds I started hearing this repetitive clicking noise from the left side of the dash near the vent area by the door. It clicked about 5 times and stopped for about 20 seconds, then clicked 5 more times, stopped for 20 seconds and again, 5 clicks, then it stopped and didn't start again. I am not sure if it is just the computer making adjustments, etc, but it is a little unsettling on a new car with 320 miles.
I thought maybe a bomb was in there. It was about 90 degrees outside and I had been using the A/C. I plan on listening again tomorrow evening when I get home from work and see if it does it again. (My car is a '15 SE 2.4L if that makes a difference). Maybe I am just paranoid, but you buy a new car to get rid of worries, not still have to worry if your car is breaking down, but I know new cars have a lot of features/settings/computers, etc and certain sounds may be normal.

I have a 2015 sonata sport and every time I close my trunk it makes a long beep sound and then goes off. The sound is almost like if you close the car door and leave the keys in the car, almost like a warning sound.

I have a 2015 Sonata Sport 2.0T with less than 7k miles on it. I commute about 14 miles to work. During this drive, I hear a clunk/thud in the undercarriage that occurs usually 2 or 3 times each drive. It sounds like it might be coming from the wheel well. Originally I thought my tires were picking up rocks on the road and throwing them up into the wheel well. If any of you are familiar with the sound of dried mud releasing from a tire or the wheel well while driving a truck, this sound is very similar. It might just be me, but I feel like it is occurring while turning the wheel/straightening it out after a turn. Today it happened while changing lanes twice, and once taking a right hand turn semi-quickly at a green light. I know that I am not running anything over that is visible while driving.
