Buzzing Noise from Rear Area

AH370Z · 10-21-2009, 10:16 PM

Yep Ive heard this buzz/rattle in rear aswell, from day 1. Not what you want to hear on a brand new car

schrute · 10-22-2009, 12:51 AM

I've got some stealth rear turn signal bulbs to install this weekend, or sooner, that pretty much requires removal of a good chunk of the rear interior to get to the bulbs. Since I'll have half the hatch out I'll try to get in there under the headliner to find the nasty buzz/rattle and kill it. Wish me luck. I'll take pics.

I have a fuel pump noise from the RR of the car, not too loud, just hear it under initial throttle blips. I don't hear it while on the highway or listening to the radio over a volume of 10 (non-Bose thank God.) I've read horror stories about the ECU noises though.

AH370Z · 10-27-2009, 07:36 PM

Any updates on this? Its driving me crazy, every time I go over a bump I hear this rattle, sounds like it might even be the rear cross bar in the hatch.

I have 1800 miles on my car and no noises or rattles.

Has anyone had a buzz/rattle from this area and fixed it?

I'll take it to the dealer if I can't figure it out, but I'd rather skip the trip to the dealer if possible.

I have the same noise (buzz) and found that if you press on the (rear area) headliner it goes away? Any info on what is causing this?

schrute · 10-27-2009, 10:38 PM

^rear of the headliner here too. I used to think it was from that crossbar but it's not. I haven't had time to take the hatch seal off to get under the headliner yet but I will. I'll take pics.

I attacked my rattle tonight and I'm pretty sure it's gone. Details > schrute's journal

Wierd stuff, dudes. Thank God, my '04.5 Touring Coupe's holding up pretty good. I've only had to replace the driver's side power window motor. Otherwise, it's been a sweet beaZt, so far. Ain't EVER getting rid of her, as long as God helps me hang in there (the $505.46 monthly note's kinda steep!) Greetings from Puerto Rico!

Am having the same problem. Service tech did not hear the noise. Occurs when car is warm and is driven over rough pavement. I do not want to get into taking the headliner apart etc.

KingZee · 02-26-2010, 08:42 PM

I've had this issue from day 1 as well. I'd really like to get rid of it. Shcrute, I read your Journal but I have a base model no sports package so I don't have the XM antenna and hence don't have that wire so it's definitely not that for me but the described noise is pretty much exactly what I'm hearing in my car. Anyone get to the bottom of this?

schrute · 02-26-2010, 10:47 PM

Kingzee, last time I was under the headliner adding dynamat I got to checking out the hole you see in the upper right of the pic below. There are two roof panels that are sandwiched together at the hole. I wrapped some dynamat around the edge of the hole as it seemed like a possible buzz source. Might be worth checking out.

I have a buzz/rattle coming from the rear. When I'm driving, it sounds like it's on the passenger side. When I'm in the passenger seat trying to isolate it, it sounds like it's coming from the drivers side. Very annoying in a $35,000 car.

I had the same rattle in the headliner near the hatch and myself and the Nissan tech actually located it. I don't have the exact specifics but there was something loose on the curtain airbags above the headliner. I duplicated the noise by driving around 50mph and hitting every reflector light on the highway. The tech heard it and he duplicated by tapping on the hatch window. Haven't heard it since. I sure hope this helps.

he tapped on the hatch window from the INSIDE to duplicate? And what do you mean by tap? Like knocked on it gently or socked it? lol

Also, do you know what the tech did to stop this from happening? Did he tighten a screw/bolt or put some tape on something?

This noise is now officially driving me insane. Schrute, has yours stopped completely after all that dynamat?
