Slight squealing noise coming from engine compartment

Dr. J 25,038 3,353 September 14, 2015 at 09:48 AM
DW has a 2014 Honda Pilot EXL with about 30k miles on it (OK we bought it March 2014).

At engine speeds around 1500 RPM with low gearing (the best I can tell; this tends to happen at low (30mph) speeds "around town" and also only tends to happen when the engine has warmed up) there is what sounds like a slight intermittent squealing noise coming from the passenger side of the engine compartment. To me it sounds like the accessory belt slipping (dealt with this before on other cars)

I'd just change it except it doesn't look fun (and is $30) - but more importantly - the car is only 1.5 years old with 30k miles - that seems WAY too soon for a belt to wear out.

Thoughts?

2014 with 30k should definitely have a warranty. Let them deal with it for free. If you don't have a warranty I'd like to hear that explanation...

Serpentine belts are much easier to replace than you think. I did one in 5 minutes. The tensioner relieves pressure so you can remove the old belt and there is a diagram to install a new one. But you can also get anti-squeal for belts to make sure it is the belt. If it stops after spraying, it's the belt.

If it's like that it might be the fuel pump. My Acura is making the same sound too (similar engine and setup).

I agree with take it to the dealer to be dealt with under warranty. Side bonus is it's documented so should they "not be able to find it" and it gets worse out of warranty it still should be covered.

The more you can tell them the easier it will be to find. If you can get it to do it reliably try opening the hood and pinpointing it.

The problem is it only appears to happen at certain RPM and SPEED ranges meaning the car needs to be moving on the road.

If you can get them to agree to it, sure. Record it and upload, please.
I felt it was fairly obvious I just meant so they could understand the conditions under which it occurs and hear it for themselves.

Squealing = Tensioner, Pully (Roller), and / or a belt ready to fail. I'd get this checked and serviced at once.

Well a bit of an update - driving around the car today (again DW's car so I drive it limitedly) - still has the ~ 1500 RPM, 30-40MPH squeal/squeal but now I notice it has something similar when making very tight, slow turns (like positioning in a parking lot). Very same intermittent noise.

Again, under most driving circumstances you never hear any of this - starting the car, driving on the highway, etc (and it's not because highway noise is drowning out the squeal).

So given this additional bit of info I'd definitely look more to belt slippage (e.g. tension and/or belt surface) than anything else.

I'm still curious why the dealership and warranty isn't taking care of this.
