Purchased M35X liquid plat with premium pkg one week ago. Only one problem; static from left drivers seat surround speaker at higher volumes. Getting it replaced next week. That's it problemwise, otherwise flawless...

The moonroof frame rattles a little while driving over bumps or whenever I make hard turns and the car's body flexes. I hear this "squeaky noise" behind and over my right ear. It's a pretty irritating noise especially when driving on freeways and their multi-grooves. Took the car over to Tustin Infiniti. They heard the noise and had the Japanese engineers look at the car. They removed the headliner, adjusted a few moonroof bracing members and added a piece or two of rubber. Took the car for a test ride and claimed success. I picked the car up and after only two miles of driving the noise was still there. Was not a happy camper. If I hadn't actually seen my car with it's headliner down I would have suspected they did nothing at all. I've driven it for three weeks now and the noise seems to be getting more noticeable - of course I could becoming more sensitive to it. Will take it back but they again need the engineers to look at it. |

Whenever my car is parked and cools down (even after short 3-5 miles trips) I hear a banging sound (sounds like a loud wind chime) from under my car. Sometimes this goes on for over 30 minutes with a chime every 5 minutes or so. The first one occurs about 3 minutes after engine shut-off although often this is a small chime. Later occurrences are louder. Took my car over to Tustin Infiniti and again the Japanese engineers looked at my car. They diagnosed the noise to be caused by the contraction of the exhaust heat shield. Umm...they classified the noise as "normal". The technician tried a fix by heating up the shield then reconnecting it in the fully expanded position. He also put a minor crease in it to allow for some flexure. Sounded promising at the time but alas the noise is still there - maybe even louder but then again I'm probably more sensitive to it now. Will take it back but again they need the enginners to look at it - say their hands are tied because the car is new. My big issue is that the noise is classified as "normal". When I first took the car in the service writer heard the noise (for at least 30 minutes) and said he had never heard it before. I actually test drove four other M's at two dealers - drove them hard then parked them and listened for at least ten minutes - heard nothing. I have been monitoring these boards carefully and no one else has reported this problem. Believe me if you heard the noise you would complain. If this sound is normal it would occur on most cars yet I have no evidence that this is the case except for Tustin Infiniti and their Japanese engineer saying so.

Replying to: drtravel (Jun 08, 2005 10:58 am) I agree that the noise is very annoying and extremely loud. I'm hoping that by replacing the exhaust the noise will be fixed.

| I have owned my M35 for 4 weeks now, with 1400 miles on it. I have a very annoying rattle noise coming from the rear passenger side (I can't seem to isolate the exact location). Is anyone else hearing that noise? Other than that by far the greatest car I have ever had and driven. Look forward to any feedback. | |

Replying to: tom43 (Jun 15, 2005 9:45 am) However, it sure beats my previous 2003 BMW which had a drivers door/window creak which wasn't fixed until the month before I traded it in for my M. |

The only problem I've had, and it's more of an annoyance/poor design than a real problem, is that the car doesn't clear a standard concrete parking block. Any stall I pull into I have to be careful because the front undercarriage scrapes against any concrete parking block. Otherwise the car has been an absolute joy. |

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.
