If you have the Touring model with the cargo cover, it will usually rattle when you have the cover extended to block the view of the trunk. Not sure why it rattles, but it consistently does for me.

yeah the cargo cover is kinda annoying at times.

I don't have a Z, although I'm considering it...there are few things more annoying than buying a new car that turns out to be a rattletrap. My first new car was a '91 T-Bird that had tons of rattles and squeaks in the crummy plastic dash and door panels. It took me a year, but I eventually found and fixed most of them. But that car left me with a bias against Fords ever since, fairly or not. In comparison my two 4th gen F-bodies had surprisingly few rattles that were pretty easy to fix. My GTO is solid except for an occasional squeak from the driver's seat (knock on wood).

I was hoping Nissan would really get a handle on rattles & squeaks, but it seems like even the Infiniti g-series has some. Since performance cars have tight suspensions and wide tires, the cabin gets more vibration so it's understandable to some extent.

I agree about the performance cars. the rattle in my 370 is intermittent and you can't hear it at all if the radios on, so at least in mine its very minor.

Being an owner of both I can tell you that it really has not been a problem for me.

awww man! just when I thought my next car is gunna be rattle free!
lol oh well hope it's better than my Stripped+Caged ITR.

Not sure if anyone else saw this, I made a thread about my popping sounds in the rear suspension

I have a Touring w/ Sport, and mine is rattle free except on hot days (90+). If my car has been sitting in sun all day while I'm at work, my drive home is filled with a rattle coming from the hatch. I can't figure it out, though I haven't taken the time to pull it apart either. It's not super loud, as I just turn the stereo up (which the Bose sounds amazing BTW). still, it's annoying like a creaking rattle. not at idle, only when the car is moving (slight vibrations). and ONLY on hot days. if it's 75 degrees or cooler, nothing at all. sounds like it's in inside the hatch area either in far back or maybe near passenger side (gas cap).

I absolutely love this car more than anything else I've ever owned, but I would like to fix this rattle.

Well, I've been in the hatch two times now. The rattle is definitely coming from the third brake light. I can't figure out how this thing is attached, so I can't remove it to sure things up in there. If anyone has any drawings or recommendations, please let me know.

Until I can figure out how to remove the light without breaking it, I have put as much foam insulation around the plastic posts that stick through the metal frame in hopes that it will keep the assembly from moving around. So far, it seems to be working.

The strange thing is that now that the rattle is gone, I remembered why I liked the car. It's sooo nice to drive when it's not rattleing. :happydance:

Tighten the 10mm nut that is equidistant between the two plastic posts.

I scoured the service manual for probably an hour and couldn't find instructions on how to remove the "stop lamp" for the life of me...but tightening that nut pulls it tighter, that much I know.

$20K for a rattle? OK, well, it's your money...

Why not spend 20K on a killer sound system...and turn it up? LOL..

Hahaha... it bothers the hell out of me!

Lately I haven't been hearing much in the way of rattles so I'm feeling better.

Page 169 of the Exterior Lighting section of the manual has it. Seems pretty easy but there's a gasket that cannot be reused, so I guess I'll have to order that.....

It appears to me that the body panel surrounding the light is very pliable also, and that could be what adds to the noise, and that the light being more rigid is what is causing it. I'm thinking of removing the light and coating the inside of the body panel with Dynamat.

Fix one rattle, here comes another...
 

I was on a mission this past week to get rid of the rattle. I took the hatch covers off three times this past week trying different solutions.

I tightened the nut holding the third light as tight as I felt I could without breaking it. I found some other forums talking about "Peel N Stick", an inexpensive Dynamat option sold at Lowes. I placed as much as I could in the hatch to reduce the vibration. Well, this particular rattle was reduced enough to hear another one.

The new rattle surprised me. I couldn't really place it while I was driving. I thought it was coming from under the panels in the cross bar. Turns out the cross bar is a great tool to identify rattles since it's attached solidly to the frame. I just pounded the bar with my palm and the vibrations carried through the frame and voila rattle identified.

This one was something vibrating (buzz) above the headliner near the back of the cabin. I was able to pop the back of the headliner off (be careful doing this..the headliner is very fragile) and could feel a bar or wires about 6 inches from the rear of the headliner. Looks like they had already installed dynamat squares up there, so i added more. Vibration gone.

Now I heard several other small rattles coming from the rear. I took all the rear covers off, spare tire out and put my trusty Peel N Stick on the bottom of the cargo area and on the wheel wells (factory had a few squares installed). Reassembled everything and I'm only left with an occasional squeak from the third light.

I can say it's truly a pleasure to drive my car now. After 7500 miles of rattles, squeaks, vibrations I can enjoy the sound of the engine (and the minor whine of the ECU..which may have to be dealt with in the near future).

I no longer have to be embarrassed about having a passenger in my car asking me about the rattles.

I have no idea how I put 7500 miles on the car while I was looking backwards trying to identify where the rattles were coming from.

Awesome! Glad you worked out the kinks. I am going to stop at Lowe's tonight and look for this stuff and give it a go over the weekend.

I still cannot identify the source of this rattle for the life of me, and it's starting to drive me crazy. Sure I can drown it out with music or RPMs, but that's not really the point.

So I had my buddy drive my car around while I layed in the hatch, and best I can tell the sound is coming from the rear panel (the one on the hatch itself that covers the third brake light). when I pushed on the large plastic cover, the rattles stopped, though I can't be 100% sure because it's not a constant rattle.

got home, removed everything, made sure EVERYTHING was tightened down, every nut, every bolt. the wire harness for the third brake light was sitting in there extremely loose so I electrical taped it still. put it all back together, sound is still there. :(

There's something wrong with the design of the rear brake light itself I believe. It must rub against the exterior aluminum in such a way that it creates that noise. It is unbelievably irritating. The strange thing is that sometimes it's not there, but other times it is very loud. you can remove the light to possibly identify the problem, but there's a gasket that will need to be ordered. I'm out of town now so haven't had the time to figure it out. If anyone solves this obviously very common issue, please let us know!!

I also experienced rattling from the passenger rear side of the 370Z. I have been battling with Nissan for the last 3 months, and now also got dealership manager to take further look into this matter. Got my car back 3 days ago without rattling anymore, they repositioned pass/side curtain airbag and assembled interior and test drive before releasing the vehicle back to me.

There is no rattling noise now; however, I noised the passenger air bag sign comes on from time to time when there is passenger sitting in the car. Checking the manuel for further information.

The rear hatch rattle that seems to be coming from the passenger side is still maddening!!!!!!!!!!!!!!!!!!!!!! I dont know what to do.

OMG! Not the freaking rattles on the 370Zs...

I thought that was in the past as for the 350.

Instructional videos for 370Z owners would be greatly appreciated!

I'm getting a terrible rattle coming from the front (sounds like somewhere near the windshield) at low RPM's. Driving me f'ing nuts!

I have a bit of a rattle comming from the passenger door. Maybe worse because of the freezing cold lately.

a rattle is no big deal, most can be sorted. common on cars, much better on the Z than most.

I must admit i find this thread pretty amusing!

*bumped*
I've had this rattle in my car for over a year. It's been to the dealer several times and it's going back in this week. I actually got in the back while my wife drove around and determined that if I pushed solidly against the hatch the rattle stopped. Not sure what they can do, but they have to do something because it's driving me insane.

I have a noise coming from behind the drivers seat, almost sounds electronic like a bad speaker, or a hollow metal against metal sound. Deff from inside the cabin behind the drivers seat. Haven't been able to determine if its the strut brace, truck cover thing, or a speaker.

I just got my car back from the dealer after 5 days for the rear hatch rattle. I'm not sure exactly what the rattle turned out to be but they said they insulated some areas in the rear and all seems good now. I still have to speak to the service advisor to get the details. I'll have to wait a few days to be certain because the first time I took it in for this it was temporarily fixed but it came back again after a couple of days.

Every car rattles eventualy guys.. My dads 90k Mercedes sl500 rattled a little bit. Hell the s550 he has now has a couple small rattles. And my moms gs430 Lexus rattled like my civic lol.

Its not the fact it makes a noise its just that the noise it makes on mine is incredibly annoying. This thing rattles more than my 87 IROC-Z, and I think we can all agree that a 370Z is built to a higher standard than an late 80s Camaro.

Eventually yes, but a $40k car that has less than 10k miles should not. My 2000 Dodge Ram has less rattles than my Z.

I also have the rattles. I can here one coming from the passanger door and also a small rattle coming from the left side of the dash. Have heard the rattle from the hatch area a couple of times. I have 8500 miles now and it has been doing it for some time now. I know that I should take it in to the dealership but I know they will say they can't here it or can't fix it. I think it is a bunch of crap that these cars rattle like this for the price tag. I can accept after 30-40,000 miles on the car. I bought a 2000 Maxima new for $29,000 and sold it with 180,000 miles on it and it didn't have any rattles in it.

I DO LOVE MY Z THOUGH!!

Keep us posted!

ha i priced out a cayman s andtest drove it and to get it any where near the competitve level of the z it will cost 70,000+ I loved it when he told me that porsches set the price buy starting with the base and adding 10,000 for every letter

Mine is a right Hand Drive Touring Z.. I've also experienced rattles coming from the drivers door.. Im not sure where but its very Annoying!!! Earlier i tot it came from the Bose speakers, switched off the radio but still... I think there's rattle snakes in the Door Panels :confused::confused::confused:

Just got back from the dealer........and the rattle is gone!!! After 13 months I had a quiet 30 minute drive. I told them to really check the 3rd brake light which they did, they adjusted the latch to make the hatch sit tighter against the seal, and they put a crapload of tape on all of the plastic pieces, and whatever combination it was, it worked. Hopefully it doesn't come back anytime soon!

I got my rattle fixed which original sounded like it is coming from the back of the vehicle. The rattling sound was actually coming caused by the passenger side airbag which the dealer secure the airbag and rattle noise is gone.

However, I recently start hearing minor rattling from the driver's side and believe it is caused by the airbag as well. If it gets louder, I will definitely go back to the dealer.

Thread res!

Last night, I discovered I had a rattle coming from my center dash. I haven't heard this before. My girlfriend was in the car and helped me locate the rattle. We found that when you open the cubby door in the center of the dash, and push down on the "floor" of the cubby (force directed towards the top of the radio), the rattle stops. I am assuming the rattle is located between the cubby and radio.

I will say that the rattle isn't like others I have heard before in other cars. It is a very faint "ticking" and sounds similar to static coming through speakers. The rattle still persists even when the radio is off.

Anybody have a similar problem and/or solution? If all else fails, I'll see if the dealer can fix it.

Yep, Nissan has GOT to work these bugs out. 'Cause she's an otherwise sweet ride, & these little annoyances can get the worst out of you!

This sounds like it might be the culprit in my car.
I've got an intermittent buzzing/vibrating/rattle coming from what I think is in the vicinity of the plastic on the passenger side B pillar.
I've tried taking out the cargo cover, the manual from the glove box behind the seat and the noise happens with the stereo on or off.

When I take mine in for an oil change I'm gonna have the guys look in all the places listed in this thread.
Thanks!

I think its a wireing harness of sorts thats tapping against the inside of the strut brace, have them look there. I remember reading that somewhere here
