Elantra XD (2001-06) :: 2002 - Constant Hissing Noise At Startup
Feb 17, 2015
I 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 have a 2002 Hyundai Elantra GLS, and it has a constant airbag light on in the dash. I have zip-tied the connectors underneath the driver and passenger side to ensure they are not loose. I took apart the center console and unplugged, replugged the airbag module, and the connector close to the gear shift. The two fuses in the fuse panel beneath the storage compartment to the left are good. I am at a block. I can't think of anything else to check, and the shop wants $90 to diagnose the problem. I've also left the battery off overnight to see if that would kwor. Still nothing.

My 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 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.

2003 Elantra GT 5-speed:
In driveway with constant pressure on accelerator (stick wedged between pedal and seat) a static rpm can be maintained for only a short time(< 2 min) time before rpm drops rapidly to idle rpm. Accelerator pedal never moves (still depressed to high rpm position) but engine is just idling away.
Note: New fuel filter and fuel pump recently installed as engine intermittently chugged/hesitated (acted like out of fuel for a fraction of a sec) especially with warmer air temperatures. Still does this but now unable to maintain driving rpm for any length of time.

I have an 04 Elantra GT and have been noticing a jerkiness when driving at a constant speed on the highway. I haven't noticed it around town or while accelerating. I also have noticed that when I disengage the clutch on the highway, the engine sometimes doesn't respond right away, or it even may surge. This has happened when exiting the highway when I disengage the clutch. The engine will slow, then speed up close to 3000 rpms.
I also had a check engine light come on and couple months ago. The code indicated that the upstream O2 sensor was bad. I took it out and cleaned it, but didn't replace it. Is this a likely culprit for this set of symptoms? If so, how can I test the sensor to be sure? I heard that I could disconnect it and run the car and see if the surging lessens, but wasn't sure if that was a good thing to do.

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.

My car has been making this grinding noise for the last 2 months. It happens when I put the car in reverse gear and slowly release the clutch. Rarely happens also in 1st and 2nd and 3rd and is always at the beginning of the transition when I am letting the clutch go. I do not know if it is the transmission, the clutch or any other part. I drive a 2002 Hyundai Elantra 5 speed manual transmission with over 120 k miles
Here is a link to a video I posted so you can hear the noise it makes : [URL] ....

I installed a Eurojet "Street" FMIC on my 2004.5 GLI a few weeks ago and ever since there has been a constant air hissing noise coming into the cabin. The noise has proven to be tricky to diagnose. It is loudest inside of the cabin and isn't audible under the hood. I boost leak tested the system and didn't find any obvious leaks. The sound doesn't appear to be boost related.
I don't seem to be loosing performance. (I've read a 2-3 psi drop is normal after FMIC install) The sound is constant and is faintly detectable even at idle inside the cabin. The sound's volume is dependent on the RPM's the engine is turning. The sound is constant whether the engine is on boost or vacuum. I can't explain this. My car isn't throwing any CEL's at all.
My mods are Revo Stage 2, 4 Bar FPR, 42dd TBE, Hyperboost DV, FMIC.

my 2002 chevy s-10 started making an air/hissing noise inside the cab. It seems to be coming from around the air conditioner controls (center front). It hisses while running, whether moving or not, does not change when the air conditioner or fan is running or not, but does improve when accelerating quickly. What could this be and would it be an easy fix or a professional job (my husband restores old cars, but doesn't do a lot with the newer ones)?

My car has been revving up to around 2-3k rpm upon startup... the mechanic says it's a faulty idle air control valve. He tried to clean it but to no avail--the car still revs up occasionally.
I can't find the IAC valce in the Hayne's Manual. Might it be called something else? The idle speed control actuator, perhaps? Is this is job for an industrious do-it-yourself?

My 05 beta 2 (CVVT) lifters are a bit noisy. On startup its a bit loud but quiets down after it warms up, but its still there. Kinda sounds like it needs a valve adjustment. Not sure if there is another way around the noise. Like a full synthetic or a heavier weight oil?

I replaced my GF's water pump, timing belt, tensioner and roller on her 05 Elantra. WHen I started the car up I can hear a loud whine from the belt.
Everwhere I searched I read that it's too tight.
But in this video: [URL] ....
At around 9:11, when the guy starts the car it's the same exact whine? Is this normal or something with a brand new belt? Or did he tighten it too much? Or is it because her timing belt covers are missing the rubber grommets, and there is a HOLE in the side of one of them. So am i getting the full brunt force of the timing belt?

2003 elantra when I start the car the belts squeal for about a minute, then whatever I do they start squealing again- turn on headlights, roll down windows, steer the car, turn on ac, anything starts the squealing again. I have had all new belts including timing belt, water pump, etc and it is only getting worse by the day.

I own a 2001 Chevy s10 4.3 litter engine 2 wheel drive truck. Every time I accelerate I hear a hissing air sound like a vacuum cleaner from the belt/pulley areas. I've changed the alternator, a pulley, the tensioner, the air compressor, and the power steering pump is only 5,000 miles old. The sound has not gone away. I have no engine overheating or anti freeze leaks and the power steering works fine. When I first changed the power steering, the wheel was super hard to turn and it would sporadically get easier; now it us easy to turn. What could be causing this sound? I rather not change the water pump now.

I have a Stock 02 f350 7.3 with 66,000 miles ... I'm sure this has been covered plenty if times, but I notice more so on cold days (-20 to 30). My truck after starting and even letting it warm up for a period of time makes a hissing sound from the passenger side of the cab near the dash/glove box area, Like I said I've only really noticed it on cold days ... It usually occurs between 1200 and 1800 rpm and it's a very touchy noise, for example I only really hear it when I'm cruising at a consistent speed, if I get on the gas a little it goes away till I bring it back to consistent throttle cruising then it comes back, same goes for when I let off the gas it goes away until I give it a steady consistent throttle again ....

I hear a bit of exhaust leak noise from engine compartment only at a cold startup, it goes away in seconds. I am 700miles from home. If it's a nonessential fix i will drive home before fixing, or, if an easy gasket replacement, I have two more days here, and tools,garage, and competent support to diy the job.

Hearing weird noises at car start-up from the engine?
My 13' Elantra Sedan has around 3K on it and a weird noise comes from the engine at start-up.
Sometimes it goes away quickly and sometimes it will linger for a while.

When I start my car I hear this very loud noise. I think it is coming from the exhaust but not sure. This only happens when the car is cold(not weather) and after a few minutes the noise is gone. I have aftermarket lowering springs on the car, do you think that caused the problem?(I'm thinking no)...
