Buzzing, propeller plane like noise suddenly started coming from the front when driving. Can only hear when windows are closed. Noise becomes noticeable above around 30 mph and increases and decreases with speed. Louder around 40-50 mph. Seems to become low pitch and less louder above 60 mph. No abnormal noise when revving the engine in park. No issues with transmission shifting. No noticeable play in wheels. Need help diagnosing the issue. Thanks in advance.

 

Is the vehicle AWD?

 

If AWD then it's the prop shaft. Common issue on these cars unfortunately.

 

No it’s FWD, base model.

 

Tire(s) may be out of balance. Same noise happened to me about a year back. Happened when I hit 50 mph though. 2012 AWD.

 

check the chrome strips that run from the base of the windshield all the way to the base of the rear window! The rubber comes loose off the trim and starts flapping in the wind when driving.

 

Thank you. Although the noise is resonating as if when a shaft is rotating and you hear a sound at certain frequency. It’s certainly not a flapping sound. I will check the tire balance and the chrome strips and report back.

 

Checked for loose chrome strips and found everything fine. Balanced and rotated tires today. The noise seems to have subsided a bit, but it is still there. Mechanic checked for the front wheels while rotating the tires and did not sense any play. Just want to mention I had replaced the transmission fluid with the new DW-1. Did not change the filter, and there is a mix of new and old trans fluid (DW1 and Z1). Did not change the filter this time. Also had timing belt, water pump replaced a few months ago. I do not think anyone of these is causing the noise, but I am not 100% sure. No issue with trans shifting and I do not think timing belt and water pump are noisy because the noise comes only when the car is moving. I am puzzled! Anybody else has any thoughts - would be much appreciated. Thanks.

 

I’d suspect it was bad wheel bearings. My bearings had to be replaced at 58,000 miles in the rear.

 

hello I have a 2010 Acura TL all wheel drive drive and is doing the same exact buzzing did u ever find out what it was plz answer back asap

 

This was literally my issue when I started hearing buzzy rattle (somewhat flappy) above ~60mph for the past two weeks. There's about 5 inches of rubber that has separated from the right chrome strip. Used small strip of scotch tape to hold it in place temporarily. Surprising to see the single replacement Chrome strip runs above $200 on Acura parts websites? Still have to look around for cheaper alternatives.

 

This tape is not designed for automotive paintwork; under exposure to UV light, it will damage your paint. Tear off any excess pieces of rubber so they stop making that noise, and for the moldings themselves, you can use RTV.

 

Thanks for the heads up. I'm ripping out part of the tape that's on the paint. Once I find the replacement chrome piece for price that's worth it, the job seems mostly straight forward. Will check with couple of local dealers tomorrow. If I can't, I'll go ahead and use RTV like you suggested. Thanks
