Jet Engine Whine just after Startup (Not Rattle mentioned elsewhere!)

elantress · 07-26-2012, 02:56 PM

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). Similar sound posted by someone else on Youtube (found link on Cargurus site):

You Tube

. 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. I feel like I have a lemon. Anyone have similar noise and what's been done to fix it?

If you do some searching in this forum it is a VERY well known occurance you'll find. Don't worry about it, it is completely normal on this car. "All systems go, prepare for launch!"

5.4FX4: I searched the 2011 - Elantra forum and only found rattle and click noises. This is a start up whine that sounds like bearing noise or belt noise. Are you able to post a link to elsewhere in the forum that has this noise. The rattle is not a concern, it's the wind-up noise that's worrisome. Here's another video on Youtube that has more easily detectable noise:

Yep, the longer, louder version in video 2 is closer to what I get every morning (you can hear a bit of it in video 1, but it's about 6 seconds in and not as long. It is disconcerting indeed.
