Accent MC (2006-11) :: CEL Came On - Noise When Starting / Revving The Engine And Getting Up To Speed
Feb 27, 2014
So yesterday during a work lunch my CEL light came on. my car only has 20,700 miles on it. and I bought it brand new. So obviously I was very nervous. I took the car straight to the dealership and dropped it off, seeing as I was only 3 blocks away from the dealership.
They ran the diagnostic and it said there was issue with a cylinder misfire. And after some more tests it led them to replace the engine coil. They drove it 5 miles and believed it corrected the issue. That evening after work when the shuttle came to pick me up, I drove the car home and no issues what so ever. Car actually seemed to be getting up to speed better than before. (car is automatic).
The issue, this morning when starting the car and getting ready for work, I hear a weird noise when starting the car, revving the engine, and getting up to speed. It is not a ticking noise, I would describe it more as a rattle but that doesn't even describe it real well.
They also did an oil change. I bought the car brand new, and have never had any issues and religiously get oil changed by dealership every 3 months.

My 09 Sonata LTD V6 was sometimes idling erratically (revving and slowing) after starting a cold engine. It never happened in the previous 3 winters I have owned it. I took it to the dealer for service and they said an ECM update was just released, described on the invoice as "TSB 10FL002 FOR COLD START ROUGH IDLE".

I have a 2000 model accent manual trans its just recently clocked 200 000 km I know the car has had problems but they are getting worse. Occasionally I have Problems starting the car in the past but it usually takes no more than 5 turns to get started but this is getting worse the other day it took about 5 min maybe more to get the car started I am guessing my starter motor probably Needs to be changed.
Next problem yesterday after I put a full tank of Premium 98 in the car its starts to rev itself changing the sound and note of the motor running constantly it has done this in the past but not so severely and It only seem to do so after putting petrol Especially when I put fuel From a servo I don't usually go to the car would have stalled more than once but didn't only because I tried to keep the revs up when it sounded like it was gunna die also I am pretty sure my fan was making some weird noises but the car has had no engine Light show and no Overheating.

Starting at about 30mph there's a humming noise that gets louder as speed increases. It doesn't seem to change if I am steering right or left and i have no steering wheel shake or any sort of noticeable bumping at 60mph. Could this just be my tires making noise, they are quite worn by now.

Hyundai makes squeaky noise when starting and stopping engine, starting to move and also when traveling at speed (during gear changing, turning, etc). What causes it? See website below for video with noise:

I got a 2002 accent 1.3 si, engine warning light comes on but doesn't seem to affect cars running, no misfires, no stalling, still good acceleration and mpg, occasional engine revving on its own, changed tps sensor and engine revving on its own was worse. Was told by hyundai mechanic to disconnect battery for 30 seconds and if light went out it was either faulty tps sensor or an intermittent non constant fault reading, light did go out for some time but is now back on.

Today I started my car (in the garage so it wasn't too cold) and everything was fine. The car warmed up in a couple minutes and I was off.
As i was driving, I noticed that my shifting was horrible. It felt like i was burning the clutch and not releasing the clutch smoothly in general.
I then noticed that when i pressed in the clutch ready to take the next gear, the engine would raise the rpm's about 500-1000 revs before coming down.
I started to wait till the revs came down to shift and that seems to work.
Why would the engine be revving itself higher the second after i push the clutch in. My dealer can't take me until Wednesday so I don't know what to do.

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.

Just this week my ESC light has come on and stayed on. Seems like the engine has been revving a bit higher too along with this light. Could this be a coincidence? The car doesn't seem to handle any differently. How to get this light off?

My car has been making this chirping noise for a couple weeks now, and I can't figure out what is causing it. It's really bothering me.
The noise is sinked in with the rpms. While in neutral or while I have the clutch in, the noise stops. The higher the rpms I'm running, the faster the sound goes. I opened the hood the other day to see if I could figure it out, but all I found out from that is it sounds like it's coming from under the engine cover.
Engine? Maybe a component near it? Maybe it's just the cold weather constricting parts to a smaller size?

In my 2007 Sonata, I hit a poorly placed high manhole cover in a dip in the road, in the dark, going 30MPH, whacked it good before I could adjust...
I then pulled the car over, it seemed to go dead, then the car did crank back up, the engine sounded much louder, like a loud rev/hum, not quiet like usual.
I next drove a mile to a c-store, transmission seemed OK, no leaks, did see a check engine light briefly, but it disappeared. Car cranked OK, headed home, same sound right at cranking and at moderate speed.
Finally, I jacked the car up on the front left, from research appears that the plastic engine shields got smacked good along the front and near the right tire and bent back quite a bit on the left side. There seems to be no other structural damage that my untrained eye could see, just one indention you'll see in a couple of the photos that I think is part of the car design at that spot.
Again, no leaks, no smoke, no caution lights of any kind now.
Photos are attached...
My Hyundai's engine now sounds like a Mustang! Hoping it's just the engine noise from these plastic covers now being bent/destroyed in some spots, exposing the engine and the typical noise you'd hear without them...

I have a 2000 accent. Automatic tranny with 167000 miles. My current problem is the car is misfiring upon acceleration and engine revving. I have to accelerate very slowly to minimize this but i once the engine revs up enough I can give it more gas and it will rev normally with plenty of power. I have had to unplug the maf to keep it driveable. Ive never had a car stay running after disconnecting the maf so this is strange to me. My accent barely stays running with the maf connected. I just got the car from my dad and he had it fixed and it ran good for awhile with the maf connected so I don't think it is the maf. But the same problem came about and we had to disconnect the maf again. And he cant remember or is not sure what was exactly fixed on the car. I've read up about the purge control valve and havent had a chance to check it out but some of the symptoms fit.

My hyundai accent has been giving me fits for about 6 months but I didnt think it was a major issue, apparently I am wrong. When it first started the check engine light would come on randomly and go off after a few minutes or even a day. Then it started staying on longer and when it would go off my car would stall. Then when it got cold twice I went out to warm my car before I left and when I came back out to leave it was dead, had to be jump started and while driving the first couple of miles it would die, it always cranked fine but it at lights or stop signs would die. Now it has stopped all together, it turns but wont start. I have a spark and we have tried the cam sensor and crankshaft. The fuel pump wouldn't go out while I was driving would it? or what could it be we are kind of at a loss.

so with the weather turning cooler i have noticed a new noise. i am at 34,000 miles and run synthetic oil ever 4-5k miles.
I hear a rattling/knocking noise when you start engine, not right away, but like after 15 seconds and it lasts about 30 seconds then seems to go away and is quiet again.
Almost sounds like a lifter is tapping due to not getting oil.
I changed the accessory belts a while ago and it did not first make this noise right after but maybe a few days after which coincided going from 80 degree weather down to 40 degree weather.
Could it be an accessory belt being too tight? If so, why wouldn't it make it on startup? I can see it going away as rubber expands as the warms but I would expect it to make the noise from starting till then. Not 15 seconds into running.

My son noticed the other day that his 2008 Accent hesitates or seems to hesitate when the A/C is on. We have driven it without the A/C on and the car drives like always, no hesitation feeling.
When the A/C is on it seems like it looses power for a split second. I have driven it too and it seems like when the A/C comes on. We have had this car since new and just gave it to him for college transportation so I know this is not normal.
Did notice that the belts are starting to crack and will replace these next weekend but don't think that is it. Not sure if the A/C compressor is starting to go or something else.

So I just got a bunch of work done on my car: the timing belt, spark plugs, serpentine belt and water pump were just replaced. I had the oil changed, the fluids changed, new front tires, and an alignment all about a month ago, but now every time i turn my car on there is a squealing noise coming from my engine (i assume a belt). Then when i get to higher speeds the entire car shakes, but more so on the drivers side. I have also noticed my brakes just starting to squeal as well, but the shaking was occurring before that. What it might be?

I purchased a second used 2006 GS300 from an ex colleague.
I've put about 5,000KM on the car, it currently has 195,000KM.
The car is/was mechanically great, until this week when I had some cooling issues..
First sign of problems was when I noticed steam bubbles in the expansion tank after the engine was turned off. I was actually filling up with oil as the oil warning light came on - 2nd time in 5000km but I guess that's normal for a car of this performance, size and age. I hadn't noticed overheating sings at this point but I remember fans being generally noisy (In SA it's in the height of summer so I didn't think much of it).
Temperature seems to be rock solid in the middle of the gauge, something I noticed as it gets very hot here and traffic is sometimes quite bad.
The next day I had been driving about 15 minutes on the motorway and I noticed the temperature gauge was suddenly in the red. I pulled over, noticed expansion was empty and filled. Decided to carry on another 5 mins as I had 2 small kids in the car and it's not a safe place to be (side of the motorway).
I finally found the radiator cap after I was recovered home and filled up with water (appeared to be very empty).
Next day little loss in expansion tank, low miles driven.
Next day needed to drive out a little further, about 50KM later the temp gauge started flipping hot then in the middle, hot then middle and then the engine warning light came on and the stability control light came on!
I was carrying water so filled up quite a lot of water again and the car started up perfectly and I returned home.
Since then I've been trying to investigate the problem, I will bullet point finding...
no obvious leaks
no oil in water / water in oil
no apparent general overheating (except the 2 times with water loss)
AC and heating working perfectly
no performance loss
driving lightly, up to temp no steam bubbles in tank w/ engine off
driving heavy at working temp leads to steam bubbles even when off
replaced radiator cap - no change
Radiator cap off and engine running cold, small water movement with a light sucking/bubbling - seems like air is sucked in every 10 seconds or so (very small volume of air into a tine whirlpool then air bubbles back). This I paid attention to, it settled down when engine heated up. Revving engine shoots water out of radiator - noticed when trying to get temperature up, I believe this is just the pump spinning up and normal.

2007 Accent GLS, US-market, Automatic, 140k miles
This is my wife's car. She called me from the side of the road while I was on a job out of town. The car had stalled while driving. She was able to re-start the car with check-engine lamp showing and took the car directly to a garage. It ran normally during that trip.
The garage diagnosed the problem as a failed crankshaft position sensor. They cleared all codes from the ECU without telling us what they were. My wife told them I would fix it when I got home. She drove the car home, parked it there and used my car until I got back.
When I got home, I replaced the crank position sensor with a new beck-arnley part. It was a poor fit, but it did go in. Now roughly every other start takes a few extra cranks. It always starts. It does not stall once started. No check-engine light since the initial episode. I just don't like the random hard starts.
Normal fuel consumption & power output. All other maintenance is up to date.

So, I have a 2007 Hyundai Accent MC (1.4, 71kw) and for the past 2 years I have a very strange problem with the car. At first, when I was reaching a 70 km/h (43 mph) the car was starting to oscillate left and right. It isn't a vibration. It's more like a shaking. Also, when I change 1st to 2nd gear, in acceleration, i feel the same symptom, more like a vibration this time.
The oscillation happens between 70-90 kmh (43 - 60 mph). I really can not figure this out. While accelerating it happens the worst.I changed two sets of wheels and 3 sets of tyres. Also, I don't feel the brakes having a problem. While slowing down, I feel no other vibration in my brake pedal, just the one caused by the oscillation.

I am seeking to identify a problem my hyundai accent model 2009. when it s cool or started with a time period gap between four to five hours. it some times not start with a try of three to four times and then start but giving some knocking sound, it went away after five minutes . once start and warm it is ok and again started when warm.
I did computer check but it result is normal and have changed also the spark plug and fuel filter but problem still exist. the problem may in timing belt -or fuel pump may any other reason.
