Hopefully you guys can give me a clue as to what it is. If not, i have the proof to supply to the dealer when i go for my oil change. Does the sound suggest that i should take it in now instead of waiting a couple of weeks before i reach the 15,000???

This is a seperate issue so I'll move this post into its own thread. This doesn't sound like the TSB either. You're saying it happens every few times you start your car? Could be misfiring, no SES light?

Finangle69 had this noise come and go too... but it was very rarely and after a hard run rather than at the start.

Let us know what it is if you take it to the dealer.

damn bro, that sounds like a rod knock, but then it goes away....which isn't possible. I wonder if it's detonating because of a timing issue that resets itself when you restart the car. Either way, I'd get it in before it takes a dump on ya and you're stranded.

The noise comes in after i have used the A/C or Heater. This morning there was no noise. Yesterday, when i took the video, I had the heater on, on my way to work. When i got to park it that i when i heard the noise, and decided to record it. Then as you see on the video, if i turn the car off, and restart it, the noise is gone.....

Weird.

No SES light, no lights on at all.

Man that sounds bad.

Just made my appointment with Glendale Infiniti for Monday morning 10/20/08.

I will keep you posted.

that really sounds horrible !!!!!
you have a video of it as proof for the dealer to see, my dealer said if a sound comes just call right away and let them hear the sound through the phone or take a phone video. Once they hear something, they'll try to see what it is. If they don't hear anything, they don't do anything.

I blame Shumby for stuffy burrito's in your intake...lol

HAHA, I got the last word now.

sure you do ^^

Thats it we are fighting. lol

i'll meet you outside

:11:OK monkey bars at lunch.:11:

I think I have heard a very very subtle form of this when me and my g/f parked in a parking lot and we were idling. I was running the latest Entourage and Heroes episodes from my iPod to the screen via Composite cable in the armrest. After using heat and/or A/C I could hear a slight slight chugging noise from the motor, less loud than this one. I was rotating between 15 minutes of car on, to 15 minutes of car off so as to not idle too long OR run the battery out from not having the motor on. When the slight chugging noise came, the restart of the car would make it go away.

+1 for parking with the old lady.

^^ what???

^^^ what you mean what? you never "parked" or watched the "submarine races" with your old lady?

what does parking have to do with this thread

NUtten but i bet he was getting lucky in his G with his old lady.

If anytime between now and my appointment on Monday, if i hear the noise I will drive to the dealer just to get a service person to document it for me. I don't live too far from there, so its not a big inconvenience.

I just want to make sure it gets taken care of.

You sure you dont have a train in the background, sounds like the subways on NYC. lol

^^ the subways suck over there, went on it once and it's mad ghetto

LoL Im not gonna lie we do this from time to time before goin' into a restaurant for dinner. In fact many times we'll have a couple of cold ones sittin in the cupholders as well, lol, a few episodes and dinner is more than enough to burn that off - who doesn't mind a little cost cutting? It's very relaxing - and the Bose Studio on Wheels does a nice job for entertainment.

Well, sir.. - I heard a subtle form of this knocking whle idling/parking...

Let's just say she has a couple of bruises on her tummy from the parking brake...If ya know what I mean. :JAMIN::BOOBIES:

lol, i didnt read ur post, i just commented against Shumby

hehe no worries - no one reads my posts!

shumby has been reading every single post i make...lol

no oil left for him to drill today or what

I read every post this is what I do before lunch.

^^ what are you having for lunch, I think i'm going to get some pizza-hut pizza from my school. I'm in that computer class i told you about yesterday right now.

Pizza is soooo greesey and that the box falls apart, which burns the crap out of your hands, but it tastes good.

I just had hotdogs on the BBQ. And now having a wisky sour

Maybe you can get your car "lemon'ed"

Thanks for the no invite



he'll find out on monday what the dealio is with his g

I am getting my Exhaust replaced tomorrow.

^^ with which one?

c ya later, next class starts soon

NoGoodSumby = FAIL

I think Maxtothecrankypants is getting his ban hammer out.

Its MaxToThePoopPants to you mister...

MaxToThePooperPants is failing us left and right on this forum.


so which exhaust are you getting Shumby?
(I'm only asking because this thread will have no updates til monday)

just stock replaced t rattels. But the FI SS Carbon Fiber is on the way be built as we sepeek i hope. Right Tony?

cool, didn't know u got those, let me know the what customs/duties fees are

will do

thanks buddy

isnt this the ticking noise everyone is talking about? i have this also.

Know
 

Please don't forget to let us know what is turns out to be.

Nope this is different than the ticking noise.

^i think this is an exaggerated version of the ticking vvel. i cant see it being anything else, especially if it can be reset by turning the car off.

I tought he was saying the ticking from the heater core caused by the excess sealent

i don't know...i read the thread earlier when it was one page and now i'm speaking out my arse. but why would the sound from the heater core be intermittent?

i don't know but it is intermittent. I whent in on day made the guy come out to hear it because i kew when i got it it for the work it would not do it. And sure enought no noise when it when in for the appointment. but they knew it was bad.

first G converted to diesel... awesome!

good one

post whore! ^

ya so lol

I was idling and checking this out in my 2000 Lexus GS400 and when the A/C is on the motor makes a light chugging/knocking noise and goes away when you turn it off - it may be normal. However it's subtle as in my G as well and not seemingly as loud as the OP's YouTube video.

is your rpm higher than normal when the noise is presented? my car has the same problem. noise goes away when you shut off your engine and turn back on. i'm gonna try to replicate the noise and take a drive to the dealer this week.

The sound almost reminds me of a starter that gets the bendix stuck, engaged to the flywheel. Its a commom problem with Toyotas but only with 100k miles or more on the clock. :confused2:

The noise while i have the A/C on is fine/normal. It remains the same as it was when i first bought the G. The problem/noise begins after i turn the A/C off. The noise heard in the video continues.

The RPM is not higher than normal when the noise is present. There is no difference in the driving when the noise is on.

When the noise comes on I am going and take it to the dealer, even if its before my Monday appointment. I just want a service person to take note of it.

on my case the rpm is a bit higher than normal when the noise is presented. and same like you it doesn't affect the performance. weird! hopefully i could replicate the noise when i bring it in on saturday.

sounds like a vlave train issue. or oil feed pump problem.

this isn't a ticking noise, it's more of a banging noise.
example of the sound: the subway system, a big rig truck or an old Volkswagen engine.

wow are you an audiophile? you so smrt.

I know I am smart ^^

no i said "SMRT"

I know!!! :p

I had the same exact noise... had to get the ECM reprogrammed with the TSB update:

Itb08-028: Noise From Bank 2 Vvel Actuator WITH the Ester oil change, and the noise is totally gone for me.

The first time they did it, they didnt change the oil to ester, and I could still hear the noise slightly. Took it back and they said they forgot to do the oil change with ester oil. They did the reprogram with Ester Oil the second time around, and all was fixed for me.

NIce. I will take in the TSB along with the one for the radio stations getting stuck......THANK YOU:bowrofl:

radio stations getting stuck, thats horrible

people listen o the radio?

I do, the jokes are mad funny ^^

oh noessssssssss, here they go again.

ok first you got to prove we stopped in the first place.

ohh yea, well I know where u'r wife is right now

I am correct, at a math thingy

update: i couldn't replicate the noise today before i went to the dealer but the guy was cool and he seem's to know what noise i'm talking about so he told me to come back on monday and put me in a loaner.

Update: I had the noise yesterday so i drove it into Glendale Infiniti. I parked in the service area, and opened my hood. The service guy immediately said that the car needs Ester Oil. I told him i was there to prove the sound just in case monday morning I was unable to replicate the sound....

He said he has had a lot of G's come in for this same problem.

Looked up...
 

Ester oil and this is what I came up with that closely fits your problem. Interesting

i just got my car back from the dealer for the tsb ester oil. the engine does seem quieter but it's still too early to tell if it fix the problem!

same here. Had my service done yesterday. I have been using my a/c all day and the engine is quite....

I will keep you posted.

I got an FX45 as a loaner, man those things are sweeeeeeeeeeeeeet!!!

but I do love my G more.....

lucky you! i got a g35 sedan.

Junyea who was the service technician you talked too, cause i'll be taking mine in two weeks. I would rather talk to someone that has a clue of what the problem is. Im from Yuma, unfortunately we dont have an Infiniti dealership and i dont want to take it to the local Nissan Dealership.

can you repost the video? the url is broken.

I took my G to the dealer (Infiniti of Peoria) this past Friday for its first oil change. I told them about the engine noise and the brakes squeaking. Without any hesitation, the Service Consultant told me they would reset the ECM and fix the brakes. He told me that A LOT of concerned G37 owners have had the same engine problem. I asked him if they have replaced the regular oil with ESTER oil. He said no, but if I wanted the ESTER oil he could try to get it covered under the ECM reset. He said the only downfall to that would be that my future oil changes would be more expensive. Since I had read that some still had the noise after the ECM reset with reg oil, I decided to go with the ESTER oil. He then offered me a loaner @ $15, I know its close to nothing but when I bought my car in TX and they told me loaners were free (atleast at their dealer). I wanted to drive an FX but they only loaned G35 sedans:mad:!! Only 1k on the loaner but no premiun options. Approximately 4-5 hours later they give me a call and tell me they just finished washing my car so I can pick up the car before 6pm or just stay with the loaner and pick up my car the following day. I was close, so I went to the dealer hoping that anoying noise was gone! I turned on the car and I didnt hear it, I opened the hood to listen closely and still nothing. So I wiped the sweat off of my forehead and walked into the office expecting a big bill. The service guy started telling me what they did to the car, and then the big number, YOUR TOTAL IS GOING TO BE $15.00!!!!!! He told me he was able to get the Ester oil under the ECM reset. GREAT SERVICE!!! I know its only been a week but I havent heard that noise again. I've driven the car about 250-300 miles since the service.

$15 it is suposed to be free
