Elantra MD (2010-15) :: Jet Engine Whine Just After Startup
Jul 26, 2012
Steps to reproduce:
1) Start Car (reproduceable with A/C on & off)
2) Wait for wind-up whine (starts out low, then speeds up, then stops) -
I attached MP3 and Wav files in .zip attached so you can hear the noise - recorded on my phone). posted on Youtube ....
Listen to first six seconds. My sound file has the noise for a slightly longer period.
My car started doing this about a week after purchase. It's been consistently doing this every morning. In high elevation, colder climate the sound is louder and longer. Car's been to service 4 times. Service Trip summary:
1) Returned as cannot reproduce
2) Replaced Starter (even though sound happens After start)
3) Replace belt tensioner
4) Service stop, tech said he would contact his rep - rep said no fix "it's normal- related to component in timing chain". (Huh?)
Service tech said he's heard a few of the 2012 Elantra's with this noise.

So I had my first oil change this past weekend at the dealer. I just noticed that the engine whine during my AM start-up is gone. They must have done something else to my car besides the oil change.

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?

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.

So I've noticed this alarming engine rattle when I first start car as if there is no oil? It only lasts a few seconds! Was it diagnosed with Hyundai? Maybe a quirk of the motor, but seems like over time would cause excessive wear on engine?

I has been quite cold in my area lately. Buy cold, I mean like 0 or a few degrees below. We also had some snow which ahs made it a requirement to drive my 4WD Ford truck with the 4.6L engine. This is a 1997 Ford F-150 light duty which is the oddball with the 7 lug wheels among others. It is 4WD with a manual transmission. The truck has close to 300k on it and I was told it had a used engine installed when I bought the truck but have never been able to verify this. The engine runs well without odd noises or clanks and doesn't burn or use oil. I have the O'Reilly brand 5W30 synthetic oil in the engine.
There has been a strange whine that comes from the engine at startup in these very cold temps. This only lasts a few short seconds and quickly goes away. I have the manual transmission in neutral so I figure it is engine related and not the transmission. It sounds like a gear noise or whine so I am assuming maybe the oil is too thick to get through the oil pump, timing chain, or similar.
This only happens at cold starts when it is VERY cold outside but I wanted to make sure this wasn't a sign of impending failure. The truck runs well otherwise and I would gladly replace the oil pump if it were going out. I was also thinking about switching to a 0W30 as the truck is mostly used in the winter anyway if the oil not being thick enough is a possibility.

I recently purchased a 2011 Hyundai Elantra GL 4 Door. I am noticing a horrible but hard to define noise. It is like a whine (like power steering pump) but not because there is electric power steering on this car, it also is kind of a mechanical grind - can't really define the sound I will try to record and post later. Any way... the sound occurs when accelerating, the harder the acceleration the worse the sound.

I just bought a 2012 Hyundai Elantra GLS (Canadian model) with 44k km. When I first test drove the car, the dealer (Honda) had the car warmed up and ready to go. As a result, I didn't notice the loud engine or anything. All I noticed is the engine was louder on acceleration versus my 2008 accord. I already bought the car but today I asked to test drive the car again (I'm excited) and noticed a loud ticking on startup? I asked the Honda dealer what was wrong and they simply said Hyundais are louder than Hondas. My 2008 accord has a ticking engine already but Honda is rebuilding the engine. This car is ticking louder than my 2008 accord. However, the car does quiet down when the engine is warm.

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)...

I have a 2012 Elantra with about 47,000 miles, and I've noticed that the oil pressure light comes on for about 2-3 seconds at startup. It never comes on while idling or driving, and the car runs like a champ. I checked the oil level, and it's good, and I get regular oil changes.

My 2012 with 5300 miles on it (oil change at 4400 miles) is now making a pretty significant lower end knocking noise at WARM STARTUP, as in when the car sits for about 10 minutes when I go into the store. It lasts for about two seconds, but it's significant and it's loud. It seems to have started about 500 miles ago and I can't say it was due to the oil change. Oil level is full and clean - I check it every weekend, even on a new car. Could this be a timing chain noise? Don't know. All I do know for certain is that this is very irritating and embarrassing for a new car. People around my car when I start it look at me like and seem to say "Really?"
Cold startup on my car is actually surprisingly quiet, compared to my Nissan Frontier V6.

I don't know what is causing this but I bought a 2012 elantra last week (500 miles on it so far). Yesterday when I went to start my car the clicker wasn't opening or locking the doors so I had to use my key to open the door. When I got in my car would start but was "stuck" in park and I couldn't shift past park (yes I had my foot on the brake). After about 10 minutes it just randomly worked... Today I was driving to work stopped to get gas and as I was stopping I realized I couldn't shift passed neutral to put in park (I could go back and forth between drive and neutral). While this was going on my windows would not go up or down. Again after 10 minutes the problem seemed to fix itself. What could be causing this?

I saw some other threads lately other people having startup problems thought i would post mines as well. Mines sometimes would startup then rattle alot/Car shakes and spit excessive smoke from tail pipe. Then sometimes it would startup up at all, No crank No Check Engine Light either
Its an 2014 Elantra GL 41,000KM with stock key, CAI. Couldn't scan any codes

I have a 2015 Elantra GT. Car has been great up until the last month. I have been getting in car and starting it. It starts and immediately stalls. You turn key off and then try starting again and the engine turns over but does not start. I am pretty sure it is a security problem. If you arm car then unarm it will start again and is fine. the problem is completely sporadic. Just last week I came out of work, turned car on,, it stalled immediately tried to start again and engine just turned over. armed and dis armed security with no luck.
Called a tow Truck and he ended up disconnecting the negative cable from the battery for 5 seconds and then reconnecting. The car started right away and was fine for a few days and now has stalled a couple times since immediately after starting but now if you try again it starts. I had it at the dealership today to have it checked, there are no codes and they could not simulate the problem so for now I have to live with it. I use this car for work and count on it to start each time. I should also mention it has a remote car starter that was put in by a separate company but was done through the dealership when the car was first purchased.

Bought a 2011 Toyota Camry about 2 weeks ago. Noticed a few days ago a severe whine I think is coming from the transmission, when it is started. The noise goes away after about 2 miles of driving and the car seems to shift OK. The dealership says this is "normal", but I've not heard other Camrys doing this.

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.

I have a 2001 Jaguar Vanden Plas, when I start it up there is a whine, the whine continues when I press gas and while the car is running. I just had the serpintine belt changed. What could be the cause or possible causes.

I once experienced the noisy engine start up.. It sounded like the engine was trying to run backwards or severe pre-ignition.

Our "new" 2010 RX is our second Lexus with fobs & push-button start. When I push the start button to start the engine, I first hear a one-second "BZZT" noise from behind the instrument cluster, then the engine starts. This happens every time I start the engine, but I've never heard a noise like that in our 2008 ES350. So I wonder if this is normal? Hearing this odd buzz noise just before your engine fires up?

Initially thought that this was related to some water in the tank, since it started when the gas dropped to 1 bar (already put some stuff HEET when put the whole tank, did 60miles so far). ODB throws out multiple cylinder misfire (codes 300, 301, 302, 303 etc). It lasts up to 3 seconds. Sometimes the check engine pops up sometimes it doesn't. there was absolutely no problem under load. does it seem like a fairly common problem ? Intake manifold clogged ?

I have driven 25,xxx miles on my 2010 Prius. Three times during the last thousand miles I have experienced very loud and scary engine noises during start up. The car had sat for at least ten hours outside in 20-30 degree weather.
I took the car into the dealership for an oil change and my service advisor told me that Toyota was aware of the problem and the noise was not coming from the engine- but a device that mates the ICE with the electric engine. He told me that although it was a loud and dangerous sounding noise, it was not something that would harm my motor. I asked that the noise be logged into my service record.
