chirping/squeeling sound at 1800 rpm
 

Hi,

As the title says, I have a 2013 accent with an automatic transmission and 63k miles. Just bought it, used. The car seems to be fine, except I've noticed that when I am giving the engine some gas and it has work to do, i.e. accelerating or going up a hill, it will squeek / chirp a bit, but only between 1800 and 2000 rpm. Its not very loud, and goes away when it's outside of that rpm range. It seems to happen more often once the engine is warm and when the car is already at speed, rather than when it's revving in park or accelerating from a standstill.

Here's a 47 second video I took inside the car while driving:
It's a bit quiet, sry about that, all I have is windows movie maker. The sound is present at 0:08, 0:16, 0:36, and 0:45.

Is this something I should worry about? I saw another thread which mentioned "dieseling", a sound like a diesel engine caused by a bad knock sensor, leading to incorrect ignition/valve timing. It sounds a little bit like a diesel engine to me, is this the same thing?

Any help appreciated. Thanks.

Are you sure that it's not a belt/pulley that's making the noise?

Hey mate, how did you fix the problem??

I am having the same issue.

Most engines have a belt tensioner that maintains tension on the drive belt.. If the tensioner is faulty the belt can slip and produce all kinds of noise.
