Engine high-pitch whistling noise

My 2005 Quest makes high pitch whistling/whining noise at idle or right after throttle

It was very noticeable at 9-10 seconds

any idea?

Mine whistles too

My 2008 SE has the same sound at very low rpm...usually when taking off from a stop. As soon as I get past 15-20 mph I don't hear it. Mine did this as soon as I pulled off the show room floor but it was very minor at the time and I thought it was lack of grease on a bearing. Now the noise is getting louder after 10.5 months and I only have 4,500 miles on it. We don't drive it much. Please share your finding with us. Thanks. joey

My wife has an 06 SL that made and makes that same noise. Took it to the dealership and they replaced idler pulley. Sounds was gone. 20,000 miles later, it is back. You can try a little WD40 on the pulley to see if it stops, but that will not fix it. You will have to replace it or live with the whine.

Have you check for any

Have you check for any exhaust leak? Sounds like some of the exhaust gas got leak out from some opening and make that high pitch noise. With the high pitch noise, I bet it might have something to do with a high speed air flow going through a small opening.....

Hope this help.

I had similar problem. The noise came around 60k. You can hear it while driving, or if you just press the gas pedal. Turned out it was timing chain. The dealer replaced it and the noise was gone.

squealing on 2007

mine is similar.....At about 1500 rpms there is a very high pitched squealing noise.....Took it to a shop and they said it was the belts...had those replaced and drove off with the same noise....not very pleased with my 2007 Quest...so far had to have a new battery, 4 new tires and now the squealing...only 33500 miles and so many troubles
