I just noticed my 2 weeks old car is making some hissing noise when accelerating. It sounds like air leak, or air movement. It is only noticeable when the window is open, and only happen at 2000rpm or higher.
View 15 RepliesI bought a new 2014 Elantra last Monday. Around 100 miles (Wednesday) I noticed it was making a ticking noise when accelerating. The sound gets louder at higher RPMs and goes away when I get off of the accelerator. You can't hear it over the radio but it's embarrassing when my passengers do. It almost sounds like a puff of air escaping or something, similar to a go-kart engine lol.
Anyways, I took it to the dealer Thursday and they drove it and said the noise was normal during the engines break-in period and if it persists after 15k to bring it back and they would see if there was something that needed tightening.
2013 Elantra GT ... Odd sound when shifts at higher RPMs. Like a chirp, or a tiny blow off valve from an old home turboed civic. Some sort of leak? When the engine is under load, it sounds like I may have some sort of minor exhaust leak, though that is nowhere near audible in the video. Very curious as to what this is.

Listen right at 0:14 when it shifts.
Here is a video I made of the "Blow off" noise I hear when accelerating/shifting (more than 50% throttle). Sounds kinda cool IMO

My wife and I are new Elantra owners, car is just about to hit 9000 miles on it. I don't know when the noise started happening, but wasn't too long ago. My wife is okay with it, but as for me I find it rather annoying that the car is so new and already making noises. I call it a click but she describes it as a thunk.
Here's the details. The car is an automatic for starters. The noise mainly happens when accelerating from a dead stop. I'll be at a red light and when it turns green, I let the brake go and gently step on the gas and click...there is the noise. Its just a single click, loud enough to annoy me and loud enough that I could hear it when the radio volume is set to 12 or so.
It has also happened mid driving when I release the gas pedal to slow down without using the brakes. Right when I release it, I hear the click...once again a single click.
Now I have taken it to the dealer as a concern because that click wasn't there when I bought the car. They told me it was normal and after waiting 2 hours for a simple oil change to be completed I wasn't ready to argue with them. But I am getting to that point that I'm ready to argue with them, considering the car is so new and still under the warranty.
So my 2001 SF GLS (220,000 km) has developed a quiet hiss on the RHS that's only present when I go above above about 2000 rpm while accelerating. Starts and stops instantly with the gas pedal. Maybe some crap in the fuel line? It doesn't seem to affect performance, but it could be a sign of something developing.
View 3 RepliesNoticed a brief hissing sound when accelerating firmly? Doesn't seem to be coming from the engine compartment, maybe from under the dash, it is very brief, a couple of seconds tops and sounds a bit like pressurizing a container just before the valve closes. Not an issue, not even a nuisance, but I am curious about it.
View 2 RepliesI have a 2005 F250 with 186K miles. I do minor work on my vehicles but have little experience working on my diesel. I was accelerating when I heard a pop and a hiss similar to disconnecting an air hose from an air compressor. Total loss of turbo power. No turbo reading on the turbo gauge on dash. No loss of oil. No smoke. Oil and coolant look fine. Took off turbo and everything appeared to operate like it should (according to YouTube videos). Inspected lines and rubber boots.
Rubber has some cracks but not certain if they are holes. How small/large of a hole would cause total loss? Was originally scared to take it to a shop knowing they could name their price. Not opposed to taking it somewhere now knowing the turbo works but obviously would rather save the money. Any tips on troubleshooting? I'm not opposed to proactively replacing parts/sensors as the truck has given me 186k and I plan to keep it as long as possible.
I have a 2015 ford f250 xlt crew cab, 6.2, fx4 with about 1200 miles on it. My questions are, I have noticed a hissing or whistling noise while accelerating. I took to dealer and was told it was the throttle plates not closing all the way.I was told they all do this. Normal? Very annoying noise with windows down. Another noise I have been having is the brake pedal makes a popping noise while applying pressure to brakes. Dealer said brake pedal assembly was out of alignment. They said was out of alignment 1/8". After adjustment within a few days popping started again.
View 6 RepliesMy wife just recently rear-ended a truck with a nice big hitch in her 2006 elantra. The aftermath was a hissing noise and no functioning a/c. I took apart a very bent front bumper, and discovered that the condenser was punctured and had spewed oil all over the place. I have a question regarding how I will recharge the system after I install a new condenser.
1. Can I just simply add new refrigerant after I install the condenser?
2. Do I need to be concerned about replacing the refrigerant oil? If so, how do I do this? Do I need to drain the existing oil? If so, how?
I have never recharged an a/c system after "cracking" open the sealed system, and I didn't even realize that an a/c system had oil in it until i saw it spewing out of the condenser.
My es350 with 4000 miles makes slight hissing noise only in Reverse (without moving the car), the sound comes from under hood, and more like air leaking noise (AC off), not loud, I can only hear it when in my garage with radio off.
View 3 RepliesI own a 2002 Elantra with 75000 miles.
This just happened recently this winter. After a cold startup I hear a constant hissing noise (for lack of better word) coming from under the hood for about 5 minutes .
This is NOT the kind of sharp noise that you would hear from a loose power steering belt but it is definitely coming from that area (towards the passenger side close to power steering belt/alternator), though I could not pinpoint the exact location.
Everything seems to be working fine and after about 5 minutes it goes away. I am not missing any fluids and don't experience any other symptoms.
I hear hissing noise when my car A/C is turned on. I have show it in Firestone and the person is like everything seems fine. I do not understand the reason. But the A/C works without any issues.
The hissing noise can be heard everyday when i turn on my A/C initially and later in between i can hear 2 -3 times a day when i go to my office.
Is it all the lexus rx350 had that noise? From the day I noticed hissing noise when I gentally press the brake pedal down and release it . And same noise can be heard when drive slowly and release gas pedal.
View 10 RepliesHaving had bit of a disaster today (shutting keys in boot that cost me 85 quid, that's why you don't buy from people who've lost the spare key), I noticed back box mounts and back box are rusting.
Is it possible to swap the standard rear silencer for the 2005 1.3/1.5 accent with the twin outlet one for the coupe 1.6?
It looks very similar and the pipe bends look the same..? What a hissing noise is when in gear and running? Stopped it doesn't make the noise, and as soon as clutch is depressed while rolling it stops.. Had a new clutch fairly recently.
So I was sitting in my wife's car and hear a clunk while the car was in park sitting in the driveway. She said it had been doing that for a few weeks now. The clunk seems to happen every 4 or so seconds while idling and is coming from the engine compartment somewhere. There is also what seems to a hissing or sucking noise that sounds like it is coming from in the dash somewhere and also happens about every 4 seconds during idle. I really haven't had a chance to look into what the problem(s) may be or if they could be connected. I am really not sure what the clunking at idle could be. I think the hissing noise is a vacuum leak I could probably hunt down when I have a chance.
View 1 RepliesSo as my first post was about all the upgrades/mods I wanted to get recommendations on, it saddens me that my second is about my check engine light.
I've noticed for the past week a little bit more of a "bump" when accelerating into gear. This Friday, coming home from work the check engine light came on. Checked the oil and gas cap, everything seems ok. I'm taking it into the dealership tomorrow and will update with their findings.
I'm worried cause I would never imagine the light to come on so soon. The car is barely two months old!
Is there a typical cause for whistling noise on Elantra ? Mine is a 2011. The whistling noise started recently, and occurs only at high speed say 80 kph and higher. It definitely sounds like wind noise, constant frequency no matter the speed. Does not sound like brake noise or belt noise, and does not change with changes in accelerator or brakes. I have taped up most gaps around the front of the car, including all around the windshield, with no impact. Note that I recently fixed a windshield wiper washer nozzle, which necessitated the removal of the plastic assembly that sits atop the bottom part of the windshield. The re-installation went well and everything seems well seated down (I had to replace 4 plastic rivets).
View 2 RepliesToday was the first day I drove my Elantra on the interstate with the sunroof open. When I was cruising at 65-70mph, I kept hearing a noise that I thought was coming from another car. It sort of sounded like a popping or thumping noise. After a few minutes, I reached my hand up and noticed the sound was coming from the metal bar that rises up a little at the front of the opening when the glass slides back. The wind was vibrating it and making it flap in the wind.
View 2 RepliesIt's only at higher speeds ( read highway travel ) that I have an issue with the road noise intruding into the cabin....mostly emanating from the rear, as best I can tell. I can live with it but I prefer not to.
I took my car to a buddy who operates a shop dealing with high-end stereo conversions, etc. Surprisingly, he said he deals with these issues all the time....including vehicles in all price ranges. He uses a product that he claims to be very effective at deadening the transfer of road noises. I had him look over my SF and make recommendations.
The product comes in fairly large sheets that are easily trimmed to conform to the spaces being treated. These sheets appear to be some sort of rubber based material. The product is applied to the inner surfaces of the car's exterior metal. Once applied ( primarily a gluing-on process ) the stuff adheres there, according to him, " for life ".
For application, he has to remove all the interior plastic pieces so he can get to the exposed body metal behind them. In my case, he would also do the rear doors so the interior door panels on those doors will also come off. Once he has access to all the areas he wants to get at, he preps the metal and glues on the product. According to him, getting all the plastic parts and door panels off, and then back on, is a snap.
My 04 hyundai accent about 2-3 months ago acquired a hissing noise which seems to be coming from the middle of the engine compartment. The car only has 100,000 miles on it.
It is a constant hiss that only stops when the gas pedal is pushed initially. I have looked all over the car and can not see any fluids leaking at all. It is pretty loud and can be heard easily outside the car when the car is on.
I hooked up my obd2 reader and found these codes:
P0304-Cylinder 4 misfire (I notice it when the car sits at idle for about a minute)
2x P0121- Throttle Position circuit range/performance problem
2x- Evaporative emission incorrect purge flow.
