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!
View 8 RepliesNoticed hissing sound coming from the rear windows when the AC is on... It's very annoying so I always crank up the volume of the music. Funny thing is when you open one of the rear windows slightly and the sound is gone. I thought it was from the roof rack but it's not.......coz the sound is there when the car isn't moving too.....as long as the AC is on.....and the rear windows are closed tight.....
View 4 RepliesSo I ended up removing my rear seats of my 2010 hatchback gs, but there is now a hissing sound coming from the rear where the seats were. The sound starts as soon as I start the car up until I shut the car off. I'm assuming that this noise has always been there just noticeable because of the seat removal. Is this just the fuel pump?
View 8 RepliesI 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.
When I'm driving and come to a stop for at least two seconds, I hear a slight click/tap noise coming from the rear of the vehicle. Then as soon as I let off the brake, I hear the noise again. I can only hear it with the radio off, and I cannot seem to replicate it when my AC is running. I have Eco mode enabled too. I have no engine/warning lights on my dash, and have no reason to believe my vehicle has an issue; just simply trying to find out what the noise is.
View 2 RepliesI feel as though my APR turboback has an exhaust leak.
There is a loud hissing noise that overwhelms the exhaust, turbo and engine noise. What it is. Sounds like a loud hissing when then turbo begins to kick it. Not normal, and it slowly has gotten worse and more noticeable.
I have a feeling its the downpipe, but I can't check it myself. When i give it gas and the hood is open (at a standstill obviously), the engine compartment smells like exhaust fumes.
Could be playing mind games with myself. What do you all think? Any way to surely test and see? I am taking it to dealership on Tuesday to double check.
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.
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.
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.
I have a 2004 F150 4.6L... There is a slight hissing sound under the dash on the drivers side when you lightly press the accelerator and then stops. No matter what speed you are going as soon as you apply the accelerator it hisses then stops. There is also the same hissing , only louder when the engine is cut off. It hisses for about 3 seconds. What could be causing this. It has been idling rough since the hissing started. The check engine light is on and showing P0420 and P0430 codes . The cats were replaced with resonators so I believe that is the reason for the codes.
View 2 RepliesHave a Whistling or hissing sound while accelerating? My 2015 6.2 seems to make this sound while under load. I took to dealer and they claim its the throttle plates not closing all the way. Claims this is normal, but to me it is annoying. Just would like to know what others think.
View 9 RepliesMy 2006 Sonata GLS 3.3 started dripping water the other day from the ceiling handle. The drain hoses do not appear to be plugged, water runs freely out. I pulled off the headliner around the place of the leak, and I can kind of see a plastic attachment with the drain hose on the corner of the sunroof frame. The water is coming from somewhere from it, but not from the hose attachment.
My question is, Do I have to replace the sunroof frame? Is it difficult to do? Or can I get away epoxying around the leak if it's small enough? In any case, how hard is it to remove the headliner?
I was just wondering if you all experienced a slight vibration of the car when stopped at a stoplight. I experienced a slight shaking of the car when I am at a stoplight especially feel it at the driver seat. I have about 300 miles on the car so far. Not sure if it is just part of the break in period? I only experience it when the car is stopped.
View 48 RepliesSo today while driving my '98 Mercury Grand Marquis home I noticed a leak was coming from behind the rear right tire.. Or I'm guessing it's a leak ? But it's kinda like a grease substance and it sure does smell bad! It's all over the backside of the tire and muffler (probably why it smells).
While driving it there is a low humming sound? Best way I know how to describe it and if I go over 60mph it gets increasingly louder.. After looking up some forums online I came across that it could be a possible wheel bearing or maybe a bad axle problem?
There is an air leak and hissing sound at the connection of the master cylinder to the brake booster. Brake pedal travels nearly to the floorboard before engaging the brake. What is the problem and how can I fix it myself? (Special note: the brake fluid was very low and is now topped off to the maximum level . Adding the brake fluid caused very little change to the brake pedal travel.)
View 5 RepliesMy truck is running fine but it sounds like there is an air leak on the drivers side of the truck. When it first happened I was passing a car and it sounded like a vacuum hose come loose. It made a loud hissing sound. Now I have come to the conclusion it must be associated with the turbo. I don't hear the hiss unless I get into the truck and the turbo starts making boost. The more boost is made the louder the hissing sound is.
View 4 RepliesI noticed a hissing sound coming out from under the car. It's more audible closer to the rear of the car as if air is escaping through a hole. Tires are good and not loosing air. When the fans turn on the hissing sound goes away momentarily and comes back. What could this be?
View 13 RepliesI have been experiencing a slight hesitation when I accelerate from a stop. It almost feels like its going to stall for a brief second then it picks up and accelerates normal until I'm at a complete stop again. I have the 2016 sport with the standard 2.4L. I currently have 2200 miles on it now and when I go in for my initial suggested oil change at 3000 miles ...
View 25 RepliesI just picked up a Sport. I've noticed 1,2 quick stutter type thing happening intermittently at highway speed going up a hill. Dealer service probably won't be able to have it happen as it only has happened 3 times in my 400 miles.
View 9 RepliesFor the last year or so i have been annoyed severely by a clunking knocking sound from the rear (possibly passenger side) of the car. The noise occurs when there is torsion occurring or a sudden change of direction. I can go over a huge speed bump or pothole and not hear a thing yet the slightest change in direction or torsion will cause this extremely annoying heavy metal clunking knocking sound. I tightened every suspension system related screw in the rear of the car and the noise is still present.
The car is lowered on H&R springs (approx. 1.4 drop) so im wondering if maybe there is an additional stress that has been torturing the sway bar links for the last 3 years causing this noise. Or could it be the shocks (which are working properly)?
