Sonata I45 (LF 2015+) :: Rattling / Gurgling At High RPMs
Oct 7, 2015
I came across this issue in my Sonata Turbo. At 5K+ RPMs, I can hear a sort of gurgling/rattling sound coming from the engine. Its concentrated on the driver's side behind the firewall. It goes away immediately once I drop below 5K RPMs. It isn't too loud; I didn't notice it up until now because I usually have some music going.
This is my first Turbo that I have ever owned. That would make sense because it only engages at high RPMs. My car has 3K miles on it. Been loving it so far!

I bought my RC F new about a month ago and have put a very fun 1450 miles on it. Ever since I got it, there is this weird noise happening right at about 2.8k - 3k rpms. It doesn't seem to happen when I'm hammering on it as much as when I just accelerate on the road to get around somebody and peak at those rpms.
Not quite sure how to explain the noise, it's kind of a high pitched gurgling. Is this normal?
I tried recording it but you can't hear it through the video at all. If you turn the volume up and put your ear right next to the speaker you *might* be able to hear it. It's much more apparent in real life.

Heading for a long weekend trip, went to pass a car on the highway and rpms went up and the car wouldn't go above 70, the car just stuttered. I pulled over and shut it off, and then it was fine. It was good the rest of the trip. On the way to the store today, it did the same thing around 35 mph today, restarted and it was fine again. t only has 9K on it.

I have a 07 Hyundai sonata that has a rattling noise only during acceleration and only at just under 2000 rpm's. I went to a mechanic who checked the heat shields and exhaust only to tell me it was in the transaxel and sent me to a transmission shop. the transmission shop told me they think its the hydraulic lifters, and sent me elsewhere.

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 .....

The problem is that it appears the torque converter is locking up so early even right after getting into second gear at speeds between 20km/h and 40km/h. This causes shuddering/rattling coming from under the hood. If I am not mistaken a torque converter should lock up at speeds 80km/h+. I've never seen this behavior on any car before. I'm not sure what kind of damage is being done either by all this shuddering and rattling going on with the transmission. I feel that this should be something that needs to be addressed via some software update. Is there any software update in regards to this issue?

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.

Noticed a rattling sound from the front end of the car when hitting certain types of bumps/rough road. Turns out my right front stabilizer bar needs replacing. Dealer has ordered part, and it's covered under warranty. However, I thought stabilizer bars were supposed to be replaced in pairs. Do I need to ask them to replace both the front right and left, or is just replacing the right ok?

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.?

I have a 3.6 4Mo always maintained on time and everything but recently, in the middle of 1000 and 2000 rpm's, it makes this weird gurgling sound, ONLY in that range, mostly around 1500. But after i accelerate out of that rpm range, it goes away and sounds perfect, immediately, like you changed a channel on TV.

My transmission is having issues switching from 1st to 2nd gear and same issue from 5th to 6th. What happens, (when attempting to switch from 1st to 2nd) RPMs rev up high (as though it is in Neutral) then after 2-3 sec it shifts, car jumps crazy and in like 1 sec it shifts down (to 1st - RPMs jump) then shifts to 2nd gear and from there it is fine. 3rd to 4th, to 5th is great, but 5th to 6th same issue, not as extreme, but similar. If i let go of gas when it should shift to 2nd gear, and wait like 2 sec, it will be in 2nd gear without jerking - Normal.
Sometimes in Park there is this noise as though something metal is hitting another metal part, and I can feel it in car - but it goes away and only happens from time to time. Also Neutral on rare occasion works as Reverse - super rare. I did Stall test (per Hyundai procedure Bulletin 13-AT-007) - no issues. Dealer ran diagnostic - no Codes in transmission. Flushed fluid - didn't work. I drained fluid again, put new fluid in and checked ATF level per 13-AT-006 - no difference. Tested Solenoids - no problem there. What could be an issue with my transmission?? 2012 Sonata GLS 2.4L with 7k miles.

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.

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 3.3L 2007 Sonata. Within the past month, after first turning it on in the morning, the RPMs shoot up to about 1400 and slowly come down to normal after about 5 minutes. It does this in park and neutral, when I put it into drive it goes down to normal. If I drive it for a mile and put it back into park and neutral, it idles at a normal RPM. If I turn the car off for ten minutes and start it up again, it idles normal at about ~850 RPMs.
After doing a bit of google research, a lot of sites say that this is a normal thing for a cold engine to do. However, the RPMs have never gone that high previously. The check engine light hasn't come on.

I've got a stock '15 F250 6.7 w/ the Diesel Site FF67 fuel/water separator and a 50gal Titan Tank. I installed the filter + tank at the same time around 2 months ago; A few weeks ago, I started noticing an odd buzzing/whirring/gurgling noise (both while the truck was running, and while the fuel pump spins up right after turning the key on). I made a quick video of it this morning:
Ford F250 6.7 w/ Diesel site filter DFCM buzzing/whining - YouTube
I thought maybe it was a filter related problem (I got some little black plastic bits in the filter after installing the Titan Tank, despite my best efforts to clean it out thoroughly before installing) - so earlier this week, I replaced both stock fuel filters, and both filters in the DS filter. Didn't seem to affect the noise from the DFCM at all.
I guess my question is - does it sound like this is sucking in air? I've never found any leaking fuel (even after a 3000mi drive from TX to VA and back), and the truck has never complained about low fuel pressure as I've read that some others have run into. But I don't remember the DFCM/low pressure pump being this loud before I installed the new parts.
I spoke to the folks at DieselSite a day or two ago (those guys are great), and they mentioned that sometimes the Ford quick-release fittings work themselves a little loose from the fuel hose during the filter install, and that putting a hose-clamp around the hose+quick release fitting may solve this; I ordered from clamps from McMaster Carr that arrived today, so I may give that a try tomorrow just to see if it changes anything.

I had to stop quick today. My ice water spilled into the gear shift lever. A mile down the road my rpms went up high and the car barely moving.

2003 jetta gls 1.8t 5spd - gts stage 1 tune(gonzo stage 2)
tt 2-1/2" downpipe with high flow cat
turbo smart splitter valve(set to divert only)
turbo inlet pipe
homemade intake with k&n filter
stock n75 valve (f)
So in first through 3rd gear my car gets 20psi of boost then at 3,500 ish rpm smoothly starts to lower down to 15psi. but in forth and 5th gear the boost drops faster, enough so the diverter valve actually opens. then the boost will bounce up and down, around 15psi. the car still accelerates but with obvious power loss.
Is my diverter valve not "firm" enough? it is adjustable, so I've tightened it as much as it can. it doesn't seem to change anything. it came with spring spacers to make it tighter, but I haven't tried that yet.
Is it something with the tune? not enough fuel, need bigger injectors? The problem is only at about 100mph, so its not a big deal. I would like to get it straightened out if possible.

So i noticed recently, last month or two, a rattling noise coming from either rear of engine or in dash that only happens when at the higher rpms like 4-6k rpm. It goes away once rpms come down.
I am thinking just something in the dash is vibrating a little. No other issues as far as i can tell.
It is very slight, almost sounds like a plastic food wrapper getting crinkled in there....

I've got a 2012 GLS manual with about 400 miles that now has a noise that concerns me. At just over 1500 rpms there is a rattling noise that sounds like its coming from the rear and underneath the vehicle. It sounds like metal vibrating. I think it could be the exhaust but I am not sure. It didn't do it on the test drive and it is fairly intermittent.
What it could be and if it might be normal? Should I take it in and get it checked out or would that be a waste of time?
