[leejoseph]

Todd, give me a call, as we need to talk about details. Read the thread below in the forum.

and the AC in the seat hardly works..

Hey that's just normal operation!

But on the way to work this morning I did hear the noise I think, passenger side, cruising at 60 or so and heard it with light throttle.

Its difficult to hear at that speed, but its definitely there. I usually here it at 25-40

Are your windows down when you hear it or does it matter?

Hi All

I have the same rattling on my 06 M35X with 40K, under acceleration I had two dealers check out the problem one said it was bad fuel. When said I use 91 or 94 Octane he then said it' engine ticking and all the infiniti do that. I don't think so.So I went to a different dealer, they said it sounds like a timing problem so they re tuned the car no rattling for one day then it came back. They said to some back if I still have the problem.

THanks

I guess some folks don't want to read what I posted or to believe what I've said. Oh well...........

[OhioAlex]

I think some of these other people are having different rattles and posting on this thread. This m45 rattle is clearly something in the exhaust, not a timing or octane or engine mount or anything else. Only thing is my dealer will not change my Y pipe without knowing for sure that is the cause and they cannot verify. Very frustrating. They said that Y pipe is a thousand dollars....

Im with you. Lets keep this thread about the exhaust related rattle.

Twice my dealer has been unable to replicate the noise. When I take the tech out in the car, the car wont make the noise. So frustrating. I havent decided what Im going to do. My warranty expires in September, and Im leaning towards NOT getting an extended warranty. I also dont have tons of time to be taking my car to the dealer repeatedly.

[MnM's_M45]

I've got the same issue in my 45. I'm glad I read this cause my dealer was thinking it was a heat shield. I'm going to print this out and take it to them.

[cerealguru]

I have the same exact problem in my '06 M35X. I took the service manager for a test drive and replicated the sound. He confirmed it was the heat shield, then said it wouldn't be covered under the dealer warranty (my car has 45K) because "it's a northern car and it has corrosion." I am not accepting that answer and will go through consumer affairs or the regional service manager. Is that service bulletin posted before still valid for thie heat shield issue? Clearly, this isn't an isolated issue and I shouldn't go out of pocket on it.

[cerealguru]

I finally got the dealer tech to replicated this on my M45 and he tested another m45 that had the same rattle/buzz. The dealership said they contacted Infiniti who said it was a known problem, #927866. I have document and the dealer said when Infiniti has a fix , they will repair mine. It's so annoying....

SO just to confirm, service bulletin #927866 is specific to the loose heat shields?

Many thanks!

[OhioAlex]

After much convincing, my dealer has agreed to change the Y-Pipe on my exhaust. This part has a cost of over $1150, but they were receptive to changing it under warranty after I did the leg work and referenced them to the previous person in Texas who had his changed. I, in fact, called the service manager Hoot and he went over the whole issue with me - could not have been nicer about it - and told me to tell my service manager to give him a call if he would like. It is being done this week, although I am out of town until Friday. I will follow up with another post on whether or not the issue is fixed, but my fingers are crossed.

[leftlane1]

OhioAlex - did that fix your rattle? Glad to hear Hoot was accomodating - he's a great guy.

[OhioAlex]

*********UPDATE*********So I had that work done as mentioned before - new Y pipe and gaskets and have had the car back for a week with NO RATTLE to speak of. Thanks goes out to leftlane1 for the info on the fix. Seems like this issue is finally fixed. I had to lean on my dealer to get the work done, but after repeated insistance, they made the repair.

[The00Dustin]

Does anyone know whether this fix (cracked Y pipe) falls under the standard warranty or the powertrain warranty?

[OhioAlex]

I am not positive but my dealer wanted to do it before I got to 60K in case there was any pushback from Infiniti - you would have to check with the dealer though.

[The00Dustin]

Sounds like your dealer isn't sure. We'll wait and see if anyone else knows. I'm not to 60K yet, but tI don't think I have the noise either. Problem is, while I don't know what causes the noise, my M45 is from Texas, here in Indiana, I wouldn't be surprised if it starts making the noise after one winter, but then I'll probably be over 60k, so that'll be kinda weak if it isn't covered.

[gigatt]

That noise is coming from rocks in the catalyst converters, to remove them you have to take apart the heat shield from the cats ...which doesnt seem right, so my dealer ordered mine today, talk to your Service people about getting the cats replaced -Good Luck.

[leftlane1]

Don't be surprised when that doesn't solve your problem. Rocks can't get into the catalytic converters - they get under the heat shield (or so the dealer will try to convince you). This is not the problem - your rattle will return as soon as you drive away.

[ArbitrageMan]

Thats correct.

The rattle this thread is referring to is caused by micro fractures in the y-pipe

[leejoseph]

My issue as well, I need to make sure this will hold true as for the bulletin number.

Jan 08, I purchased a brand new 07 Infiniti (M35x) and for over a year I fought with the Infiniti services team to address a “rattling, pinging, rocks in a can” issue coming from the exhaust system beneath the front of the car. Finally it took the regional manager to come down after filing two complaints with the inter-circle consumer affairs department. From that point; it took both of us to go into the garage and actually have the tech take the "heat Shield" off and to our demise. We found that the small piece of material inside of it was deteriorated. He (Roger Gettler) made them order a new heat shield which corrected the issue. Outside of that; I had additional issues from the “middle headrest latch being broke, the wood molding on the driver side came a loose on the door, the controller in the passenger side mirror went out and the last straw was a rattling in the passenger door they could not fix and needed to replace the whole panel.

Now; the new and current general manger for Charles Barker Infiniti tried to ease my pain recently by working a deal on a 09 (M35 Sport). I have owned this car roughly two weeks and again the rattling issue has returned. I have had an intermitted issue with the passenger mirror when putting the car in reverse and the AC in the seat hardly works in this car.

Upon giving Charles Barker an attempt to resolve the issue on July 8th; I'm not only disappointed, but very dissatisfied because from one perspective I'm being told it's just how the engine sound on the cars and is normal, yet it doesn't happen on every car. From another perspective; it was identified by tech as a rattle or pinging sound, but yet they cannot duplicate it on other models or fix the issue.Additionally; the rude comments from the technician should not be tolerated by the company. Every time the technician named "Lance" has to ride with a customer to identify an issue. He is very rude and disgruntle toward customers. In fact; when explaining the issue; Lance makes rude comments "that if I want him to tell them that I would like something change out, then that's what he would tell them". He is the technician and though he here's the issue; when speaking with the service manager he then tells a slight different story or regurgitate it differently.

I'm now looking to take legal action against Infiniti because "WE" as customer should NOT have to drive a $60 thousand dollar car with a rattling sound on acceleration. I no longer want the vehicle and looking to return it and/or take whatever measures necessary to square this matter away. This same sound has been experienced by many customers across the US; they either end up going back and forth with the tech teams. Or have had the issue identified and resolved the issue in one of several different ways such as; wedging something between the shield and exhaust pipe. This is supposed to be a top of the line vehicle that should not be experiencing such issue.

[zags]

Just recently started hearing this rattle/coins in a can noise myself. My 06 M35 has 48k miles now.

Time to get it into the dealer...does anyone know when this sound is most prevalent and easiest to replicate? Just in case I have to replicate it myself for the techs.

[zags]

And to clarify is the TSB #927866 for the heat shield or Y pipe?Both?

[OhioAlex]

TSR is for the heat shield, but that is not the problem IMO. My rattle started at around 38K miles, and took nearly 20K to get fixed with about 4 trips to the dealer in that span. The easiest way to hear the rattle is at around 2500-3000 RPM with the car moving. I was unable to replicate the noise in neutral or powerbraking (as some other have). Dealer said the load on the exhaust while moving influenced that. Good luck gettting it fixed - it is very annoying but once it's gone, you'll be happy you chased it down.

[leejoseph]

Mister Hernandez, I have several concerns because I contacted your office several days following the arbitration. Also, I have recently contacted your office about the issues that have worsened.

* Days after the arbitration I went to Passport Infiniti and they found they needs to change out the "y-pipe" on the exhaust.* They also attempted a repair of the rear speaker deck and now I assume it has came a loose again, because the noise is back.* They still did not fix the rattle in the sunroof, due to time constraints* Several after receiving my car from the dealer, the whole exhaust system has been shaking and ratting. * I assume they did not put clamps and tighten the pipes accordingly. Call the Barker Infiniti but they cannot get me in till 12/17.* Not the car hiss and make more the rattling sound even more and I assume it's due to the weight of the of the exhaust system hanging lose.* The arbitrator made a decision without some of his notes that were mixed in with mind.* He also states he did not hear the sounds from the exhaust as everyone else in the car.* Even the admitted he heard the slight difference as he puts it. * The arbitrator did not acknowledge the fact I brought reports from dealers and consumers who have had the issue fixed.* The arbitrator only mentions that Mister Gettler brought in documents and the exhaust and the engine* We have to call attention to the arbitrator hearing because he did not here any of the sounds that everyone in the car heard.* This arbitration appears to have some type of bias as it appears that Mister Gettler and the arbitrator have worked together before.

I will be pursuing this matter further by contacting consumer affairs and the justice system. There needs to be some action taken against dealers as such for the quality of work and having someone in the corner of the consumer. Because now my car is worst than before with louder noise and the ENTIRE exhaust system is hanging lose. Noting the dealer can only see me on December 18 to repair the issue. Now, there are possible stress fractures in the exhaust system which could be giving off the hissing sound on top of the rattling during acceleration now. The rear exhaust section of the vehicle is knocking around every time I hit bumps in the road. This is unacceptable and will local media stations about this matter. Lastly, I have contacted your office twice and left a message for you and no one has returned my call.

Thank you

[mpgmusic]

Leftlane1- I wanted to thank you! I have had the rattle intermittently and several dealers could never replicate it (of course) when they drove it until this week. It finally rattled for crest Infiniti in Plano. I printed out this string and showed them your solution from Grubbs Infiniti and they did the same repair. The rattle is finally gone. Thank you Leftlane1 a million times!!!

[07M45ATX]

Want to thank leftlane1 on this one. My 07 M45 Sport only has 34K on it and this rattle, which fit the description here to to a tee, was driving me nuts.
I took the Infiniti mechanic on a ride, reproduced the rattle, and wasn't getting very far in getting this addressed. Had the heat shield, rocks fix done to no avail.
I found this explanation and printed it out and back to the dealer I went. I have to admit, I never would have though it was an exhaust issue, but the service adviser warrantied the Y-pipe replacement and the rattle is gone.

Very happy to have found this forum.

Thanks!!!!!!

Well after reading through this thread after bieng directed from E brake cable rattle, is thread here convinced me its what my car has the coin shaking in a can noise, I described it as loose chain dragging at very low rpm. Now that my car has no warranty I don't know if this problem would cuz any further problems or do dealers change it due to recall of the Y pipe. Please if some one can tell me no warranty here = I have to pay for this repair on my own?

Thanks in advance.

The Y pipe is gone, rusted out and needs to be replaced. I had the same thing and ordered the pipe on line, had a small shop install it and when they showed me the original pipe it was so badly rusted that when I squeezed it with my hands it broke.

Check the Y pipe- there is a thread about it somewhere. I would be surprised if it is not a failing y pipe - you car is 7 years old mine is 6 (live in a climate where road salt is used).

Good luck

Hi guys, I have this same problem...does anyone without a warranty know if this is an out of pocket fix or if Infiniti is now stepping up to the plate?

Thank you,
