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

Many thanks!

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

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.

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.
