Resolution of my two sound problems by drtravel

Spoke with the owner and service manager - both of whom said my noise was definitely not normal. The called the Infiniti engineer from Japan who brought along a few other factory engineers with him who did all the repair work.
 
They replaced the entire sunroof assembly which took care of that problem.
 
They also replaced the Y-Pipe for the exhaust system - this might have been a newly updated design but am not sure. They all seemed very interested in this problem. Anyhow the noise is no longer present.
 
Dropped the car off Monday AM - it was ready Tuesday PM. Suprisingly quick considering they had to remove and replace the headliner plus get the parts. I'm guessing that the factory engineers had some pull.
 
So now I give Infiniti two thumbs up!!
 
PS. As far as the engineers knew I was the only owner who had these two problems, which makes the new M a very reliable car.

I have the same problem. The rattle in the moonroof drives me crazy. I went to the dealer and he said I was the first person to complai about it. They tried using some insulation tape but it did not work. I am not sure I want them to ttake the roof assembly apart and repalce the sun roof. I will play it by ear and see if the rattle continues to annoy me.

I get the same loud bang about 5 minutes after I turn off the engine. Happens about 50% of the time. I hae not spoke to the dealer about it yet. I will watch and see if it gets worse

Loud engine noise by infinity2

I have an m35 and really like the car. However, the engine seems really loud at times and I am wondering if it is normal. Anyone else have that problem?
 
Also, A moon roof rattle and loud banging noise coming from under the car after the engine is off for about 5 minutes are problems as well.
 
Anyone else have suggestions of the same problems?

Engine sound under acceleration is normal given the gearing on the M35. Its higher pitched than my BMW 530i was but otherwise the same. The Moonroof clicking I had went away by itself. Ironically, the exhaust system heat expansion/cooling noise on shutdown is still there although not as loud. If it continues I'll have the dealer look at it during my next oil change.
 
With more than 5,000 miles behind me the car runs great. The electronics are first class and beat anything I've ever owned.

Interesting. I had a moonroof rattle (kind of sounded like two small glass globes knocking together) from the rear passenger side of the moonroof. I have not heard it for some time now. It was usually present for most rides but went away for short periods. Now it appears to be gone.

moonroof acting strange by pete15

I have had my m35x since late March. Recently the moonroof stopped opening or closing all the way when I hit the button. When I hit the button it goes an inch. If I hold it down it goes an inch. It happens in either open or close. I can get it to open all the way and close all the way but it takes dozens of button pushes to do it. It had been working fine until about a month ago. I am scheduled for a visit to the dealer in July.
 
Is this a malfunction or an incorrect setting? Anybody else have this kind of problem?

Had I think similar problem. A piece of plastic on the right when popped up was acting as a splint. It was fixed at the dealer in the drive and I was on my way with no problem(s) since.

I have also had my M35x since late March and my sunroof stopped like yours. The dealer ordered a new motor and replaced it. Last week it happened again. They are now telling me that the rails need to be replaced as well. This will happen next week.

Steering feel by ewl88
Jun 28, 2005 (4:43 pm)

I posted this earlier in the main infiniti m35/45 area but I guess this is the more appropriate place...
 
I have ~1200 miles on my m35x. I've noticed my steering wheel seems to have less resistance (feels "looser") esp at lower speeds ~20-25 mph compared to when I first got the car. Then it firms up to where I want it when I reach highway speeds. Is that expected? Is this just a function of the breaking in period? (I think I preferred the steering feel at lower speeds before)
   
Has anyone else noticed this? It's subtle. So much that I'm wondering if it's just me and not really a problem at all.
