Say it isn't so cabin air leak
Say it isn't so cabin air leak
Well ladies and gentlemen for what I put off for a while I have finally accepted and come to terms with. My car isn't perfect. So as most of us do we drive with the music on and rarely with it silent. Well I finally did that a couple times on the freeway. And I notice that air whistle sound really pick up inside between 60-80 mph. At slower speeds you can't hear it. And from my vantage point it's all coming from either the front or rear passenger side or both. So I had my dad drive and I sit on th passenger side and sure enough it's pretty noticeable. The hard part is where is it coming from exactly. So I took a couple pictures of what I think may cause it. I took two of the inside and outside of the car. And the same for the passenger side. And from what I can tell on the passenger side the lining of part of the rubber bulges out and doesn't seem flat like on the driver side. Also on the outside of the passenger door if you look close that corner doesn't seem to sit flush either. So I made an appointment for Tuesday to drive with a master tech. Anyone else having this issue or maybe ha not tried it yet?
That bites, my only suggestion would be to go on another ride with someone driving and take video proof of the noise. My luck has always been when someone from the dealership gets in the car it never wants to reproduce whatever it was that I brought it in for.
Yeah I am going to have the tech listen and really give me an honest opinion. To what the dealership said is that Nissan really wants quality on these cars and wants to fix everything. Lol I don't think these can get that high. Don't they cut out at 140 or something?

UPDATE: So I went to the dealership yesterday and took a test drive with a Master Tech and head foreman of the whole service department. I drove first then he did so we could have two perspectives. He told me I can make a couple adjustments, but these cars are designed pretty quiet and of course really aerodynamic. So anything above 80 all bets are off. I have test driven a couple Maximas previously before buying my car, but when you drive them with a Salesman there is usually constant talking and or music playing so you hardly get to test out the dead air of the highway. Long story short he adjusted what he could and it does seem to help. But I think my ears just aren't used to what a Maxima sounds like vs what I had before an Altima.

That's not normal even above 80, the 16 Maxima rentals that I get and I have them often when I go out of town for work are very quiet above 80. The one I have currently a brand new 16 with 384 miles on it, took it to 94 mph on a stretch of I5 in Northern California and it was very quiet. No unusual wind/whistle noises at all!
My first guess would be that somewhere one of the doors has insulation that is not in full contact with the door opening when the door is closed, leaving a crack where the sound of outside air gets in. If the sound is worse on one side, the problem is probably on one of the two doors on that side.
I created a similar problem when I put rain guards at the top of all four side windows on my 2009 7th gen, and it took me weeks of trying different shape deflection molding on the side of the car near the base of the windshield before I found a shape that nullified the whoosh caused by the rain guards.
Finding an air leak around a door can be difficult. Maybe having someone else drive while you take turns in each seat with all air circulation (AC, heater, etc) off and try holding a single sheet of something very thin (toilet tissue?) right at every spot along the inside edges of every door, and it you see the tissue move at all, there is probably a tad of air getting in at that spot.
If you find nothing wrong with the doors, you might try the thin tissue thingie under the dash and around the edges of the sunroof (if you have one).

Yeah i am going to have to try different methods and see. Because I am sure they were trying to do everything but replace all the weather striping. So if I do find it then they damn sure will replace it.
A36-SR I know we don't know one another but since you are close would you mind driving my car and I can sit in yours while you drive to see if there is a difference?

Pressurize the cabin by turning the air conditioner on high with the windows closed and outside vents open so it's drawing air from the outside. Have to wait for a not so windy day and try to have someone with a vape go around the whole vehicle. Any disturbance is where your leak will be. And this way you are able to narrow down better. Maybe do this in a garage with the garage door open. And when whomever is blowing the smoke, make sure that person blows it out slowly so there's not much movement.
Damn that is a genius idea. I have have a bunch of people that vape with heavy clouds. I will do that. So while they do this should it be blowing in a general direction so the whole car fills up? Also at this point do I turn the air off after the cabin is pressurized?
No you blow the vape smoke from the outside and blow against the doors and window area, the air from inside the vehicle will be pressurized and try to equalize by exiting the vehicle. The air that's disturbing the vape smoke from the outside will point where you have to carefully inspect.
