Getting this weird noise everytime I go over 60mph, sound like it's coming from driver side front. I noticed lots of people have complained about the driver side window seal, but I don't think this is it since there's no hissing or whining noise.

It sounds like very quiet: "Flap, flap, flap, flap..." and as soon as I go below 60mph it goes away also it seems get more silent when you go over 80mph. I thought it might've been front plate flapping which was not secured properly but that's was not it.

I wonder if it could be the plastic cover under the engine since if you push it up it seems to move a bit before it hits the frame? Also I can't feel anything weird in steering when I hear the noise.

 

most likely it is the plastic cover under the engine.
mine comes down all the time since i have an aftermarket bumper.
i just usually ziptie it back up.

 

I have so many lil noises coming from my G that I just gave up. Love the car.. but you don't expect these issues from a 35k+ car.

 

damn i thought i was losing my mind, i thoguht it was my wheel at first....uneven wearing or a rock stuck in the tread. but its neither and my friends who ride in my car say they dont hear anyhting but i DO

 

.. did you happen to do some sort of a oil change recently?..

last time this happened to me.. the guy didnt bolt ALL the screws on the cover that is on the bottom of the engine.. and this caused flapping noise.

 

Unfortunately I'm not 100% sure when it started happening - now when you mention it, it might've been right after last oil change... luckily I'm going in for oil change today and I'll ask them to make sure it's all bolted down.

 

Odd... it's little better but the sound is still there - the engine cover feels very tight, at least in front. I have to do some more poking around.

 

it might be one of the wheel well liners where they connect to the front bumper. those are the ones that always come out on me.

 

I dont understand why everyone comes on the forums to complain about noises and wonder "what is it". The dealer can fix this stuff so you dont even need to worry about it. We can't see your car and Im sure there are not many cert. Infiniti mechanics on here This is why we have warranty. Same with the "so many rattles thread", the dealer can fix all this stuff, they know what the issues are. I think some people just like to complain(Not the thread starter, you have a valid concern, but you guys know what threads I'm talking about.)

 

Argh! Went through the whole car with fine-tooth comb and can't find anything that would cause the noise. Wheel well liners are ok, the plastic cover under the engine is very tight, remove the plate frames just to be sure.... still the sound is there between 60-80mph. Maybe there really is something going on with the driver side wheel.
