Subaru BRZ strange squeal/screeching noise while accelerating/decelerating
Hi all! I'm new in the forum and this is my subaru BRZ from 2014. I have tried to search everywhere to find if someone had this problem but I didn't find anything about it.
As you can hear, there is a strange noise, something that is screeching in the engine bay. I have tested the car these days and it's seems like the sound comes out after strong acceleration, like hitting 7000 rpm, but it's pretty random; if i drive under 6000 rpm it won't happen (at least it seems). This is not related to the clutch; it can be engaged or not, the sound still remains if it comes out. Also, it lasts for like one minute or two, then it disappears. I haven't CEL and the car still runs very good even if this squeal is on. You can hear it in the first rev and in the third pretty clearly. Hope this will help: Thanks to everyone who will reply Last edited by Stefforegaz18; 05-21-2021 at 05:48 AM. |

Hello Stefforegaz18 and welcome to our forum -
Personally, I can't hear anything on your video. Maybe because my ears are too old - How many miles on your car? Do you have any engine modifications? The first thing I would suspect is the serpentine belt. It may be wore out (slipping). You could either put some belt dressing on it or replace it. Also check the idler pulley. Make sure it's not wobbling or dry. Others will be along soon with some other ideas - |

Anyway, I have to go to the dealership in the next two weeks, so hopefully they can identify this sound. I'll make another video where this sound does not appear, in orther to compare it with the previous video. Last edited by Stefforegaz18; 05-22-2021 at 07:31 AM. |

I bought this car with the militek already mounted so I'm not that used to with the stock sound. Last edited by Stefforegaz18; 05-22-2021 at 06:51 AM. |

So anyway, I have been to the dealership and they told me that the "problem" is probably related to the VVT system on the right side of the engine (looking in front of it). They said that right know I do not have to be worried about it, also because there's no any check engine light on.
If I've got any new problems I'll update the topic. Thanks for all the replies! |
