I'm not certain wether it is me, or if my particular G35 (I purchased in March) is unique in regard to brake power onset, but I have never had a problem with the brakes since after minute 1 of driving it about...
To add to this, what many have called overly sensitive steering just off center, and a twitchy gas pedal have also given me no troubles whatsoever.
I will admit that I have to adopt a different driving "personality" when in the G35 as far as the steering, braking and accelerating compared to other cars, but it isn't over the threshold of being dangerous or even "annoying" by any stretch.
A benefit of driving the more, I like to refer to it as "responsive", controls in the G35 is that when I drive other people's cars, they have actually commented how smooth and gently I drive *laughing*
On the subject of steering... I find the G35 to be precise, in direct contrast to what others have called "overly sensitive, or twitchy" and that hitting the apex of a corner a few inches from the curb illicits far more of a feeling of accuracy than in many other cars I have driven that have since seemed rather "floaty" and slow in the steering department.
Accelerator pedal input vs acceleration is admittedly of the three (acceleration, braking, steering) the most significant departure of what seems to be the mainstream behavior of most cars, but again, it prompts a requisite smoothness on the controls that does not cross the threshold of unacceptability, which would be evidenced by people never being able to get used to or adapt to its characteristics... In my particular case, the modulation is perfect with a main tendency to launch with authority, and with only a subconcious adjustment to transition to smooth sedate acceleration. However, this one did take a bit more "thinking" about until it became second nature, but now I instinctively tie it into the car and its invoked right when I sit in the drivers seat.
I believe that the complaints about the "grabby" brakes stem from an unfamiliarity with the car, and the fact that right off the bat, the brake action is stronger, and thus "different" than most other cars. This is undoubtedly a spinoff of the outrageously good braking performance the G35 enjoys at speed. Each performance gain is typically associated with at least a behavior change in some other part of a car's spectrum, and I'm pretty certain that the grabbiness can be attributed to this... Many have said that other cars can have brakes just as powerful and not be grabby, but since the braking performance of the G35 has been compared to Porshche 911's and Ferrari's I'm guessing that they didn't have the monetary resources to make the brakes perfect in ALL arenas of operation, and chose instead to hit the important aspects of operation and compromise some in other areas. In my read, for the cost of the vehicle overall, I think they hit the mark quite admirably...
Just my ramblings...
Have fun All!

Thanks for the details on the braking and steering. Seems like you know your "stuff". How has the interior held up so far? Specifically the faux titanium surfaces if your car has it. Just curious as I will be putting an order in for the 6MT Sedan in Jan. '03. Thanks in advance and good luck with your car.

Has anyone else seen this?
I am taking it in for service next week.
Now I know that you can manually adjust the location of the car. But of course, this will only work when I'm at a complete stop...try doing that on the freeway! Furthermore, I have gone so far as to make the adjustment, position the car correctly at an intersection, then drive around the block. When I come back to the starting point, the nav system indicates I'm about 100 feet back from the intersection.
Since the system still operates even outside of the range of satellites, I'm wondering if the primary readings are from the spinning of the wheels with only secondary input from the sats? It seems to correctly position the car whenever I start the engine, then loses touch as I drive. If that's the case, is it possible the system was set up for the 16 inch tires and my "sports-package" 17-inchers are throwing it off? Given that it would give me almost 9.5 inches more distance per wheel revolution, that could possibly account for the loss of 100 feet over time, then getting reset when I turn a corner or if the system gets way off course. I'm not looking for military precision here, but I guess I was looking for something better than this.
I'm going to have Infiniti at it during my next scheduled maintenance, but I was curious to see if anyone else was having this problem and what, if anything, has been done to correct it.
Thanks!
I am not certain how much this restriction degrades the positional accuracy (it wouldn't seem like it should have a significant effect the majority of the time) but I could be wrong.
One thing I have read about Magellan systems is that they include positional accelerometers that continue to predict location when satellite positioning is either lost, or severely degraded (4 satellites or less). Although these can't be as accurate as the Inertial Reference Systems on Civilian and Military aircraft, they certainly must do a much better job than simply tracking your last known course and speed until the signal returns.
Does the infiniti System include this Magellan type of IRS system? If so, it might explain how your location gets so far off (the spot you were mentioning might be a bad reception angle/area and it reverts to IRS positioning each time you are there), or it might even be a simple situation that all the satellites that are visible to your antenna are all located in the same general area of the sky (the biggest advantage to being able to track as many satellites as possible) and since we know that the mobile street GPS systems "snap" your location to the nearest valid road in the database, in the case of yours telling you you were on a frontage road next to the freeway, the amount of error might only have been so much that you were "closer" to the frontage road than to the freeway, and so it bumped you over there... I have had this happen to me even with a 12 satellite tracking unit receiving solid signals from 10 satellites with good dispersal. with less than 15ft accuracy the only thing I could attribute it to was innacuracy in the map database and not positioning. Subsequent tests confirmed this when I drove the same stretch of highway and stayed in the fast lane farthest away from the frontage road and for the one short section, it kept me on the freeway instead of wondering why I was blasting down a dirt road next to the freeway at 80mph
An innacuracy in the database of street positions in the Infiniti system for that specific location you were describing (at the intersection) would be a plausible explanation as the system is probably trying to calculate a "best snap" position for your Lat and Lon to keep from placing your position on the screen in the middle of a building or an embankment. The fact that this repeats for you each time would seem to confirm that. The system is saying to itself, "He can't really be inside that building so I will put him..... HERE!
Try going to that same spot at a very different time of day when the satellites are in much different positions in the sky, see then if it puts you in the same spot 100 feet from the intersection. If it doesn't, then it is most likly an error in the Source map and not completely positioning accuracy. Does the Infiniti system have a page that shows you where in the sky the satellites are? The more satellites you can get "surrounding" your position, the better the accuracy will be.
As long as it doesn't happen constantly, I would think it is a small price to pay for such a clean and well integrated install as the OEM system.
If it is intrusive in its error maybe an update to the NAVtech Sourcemap (Infiniti uses NAVTech don't they?) that might solve the problem.
Oh, just as an aside, I thought it was a rather nifty feature that since you can track so many satellites with a 12 sat system, your Z position can also be calculated with some impressive accuracy... Didn't you ever wonder how the NAV system knew you were on the skyway right above the street that ran directly below it and not down on the street level
Good luck to you!

With that said two other items come to mind. 1) Mine often exhibits offsets. Especially in circumstances where my DVD map info is insufficient such as really new construction that rides next to adjacent roads. It may still place me on the old roads it "knows" about if they are withing about 100ft of the new construction. This is not unusual even with a maximum # of Navstars it will try to associate your vehical with a known road. It won't try to route you through a marsh just because it has an accurate lat long and elev. 2) Most Auto Navs tie into the computer to get VSS (Speed sensor) info to refine position based on accurate speed in order to make up for comm latency (no matter how many Navstars you see - there is an uplink penalty). If you have modified the wheels so as to effect the VSS info then that will effect the positioning of the vehical, although in a forward direction not (I think ) parallel to the direction you are headed.
I would contact Infiniti to get a reading on how the modifications to the VSS might effect the Nav output.

As far as speculation to the system snapping you onto a road goes, I haven't seen that happen. I live in a townhome complex, and my unit is buried in the middle between the streets. When I turn into my driveway (which is not on the map), the system correctly shows my position in between the streets.
Also, I experienced serious rattling in each of the front doors w/ bumpy road conditions and/or when the radio was on (rattles w/ the base). The dealer "resecured" some component in the doors that has to do w/ the auto windows. That fixed what I would describe as the "radio rattle." However, there is still rattles in ea. of the front doors that stops when you apply pressure against the door from the inside. I intend to have the dealer address this problem at the next visit.
I absolutely love the car. For the price, it drives incredible. My only complaint to date is the rattles in the interior. A friend of mine has a Maxima w/ 40,000 miles on it w/o any interior rattles. I expect the same.
As a side note, I've driven it in 2 significant snow storms and it handles like a dream. I have to keep reminding myself the roads are in bad shape so as to not push the speed too much.
I'm about ready for my first oil change but am not sure exactly how to get the cover off. Theres a fastener of some sort in the middle of the cover which the manual doesn't explain how to get out. My guess is that you pop the center out with a screwdriver. Can anyone tell me if that's correct?

1)The passenger side door/window rattles. It stops if you put pressure on the inside of the door. (same complaint as above)
2)The dash board rattles, but we can't pinpoint where exactly.
3)When you rest your arm on the armrest it rattles (there may be a connection here with number 2 above).
4)Where the driver side vent and door meet rattles.
Does anyone have these problems or know a fix for any of them? WE NEED HELP!!
We also had the seat belt clicking problem and it took the dealership 4 tries to fix it.
Is it all right or something wrong with it.
Thanks,
I have a Brilliant Silver with sport package/winter sport package/OEM aero package with just over 600 miles on it.
The one question I have is about the windshield wipers. I believe that they are supposed to speed up and slow down with the speed of the car. I have yet to see this. Do the wipers need to be placed on a certain setting for this to engage? Our Acura does this if the wiper are on the fastest intermittent setting. When I did this on the G35, I didn't notice a change, even at 55 mph.
The other question I have is on the audio system. What is SCV (I think those are the right initials)? The manual doesn't describe it. Right now I have it on the OFF position.
Thanks.
I've only had my sedan for a week now, and it hasn't rained in that time. I haven't played with the wipers yet.
scv as noted above adjusts the audio volume for your speed. i have mine set to "mid" and i don't notice it - but I think that's good since i hardly ever adjust the volume down when i stop or back up when moving and outside noise increases. i had it on 'high' but i thought it was too noticeable.
I have about 9,500 miles on my G and I have the driver side door rattle, off and on. I am going to have them look at it at the next service. It really does bug me when it starts. I just can't forget about it.
The only other problem I had was the roof inside separating from the sun roof on the back part. I let the dealer guys fix it as I was not sure if it was going to be a problem. They popped it back in and it has been fine since, but I am wondering why it came loose to begin with. Hopefully I will not have any more problems. Pat
Youll have to replace yours too.
worse yet, when I started engine this morning, the engine vibrates and noise a lot during warming up, I can feel the car vibrates at 1200 rpm during warmup. on the road at traffic light, the idle at 500 rpm and engine does not feel stable. I have been driving many Japaniese cars, none of them has unstable and noisier idle speed like my new G35.
did anybody has or know these problems? please someone calm me down? should I give it more time before checking with dealer's sevice?
However, since you mention vibration and a service light, I'd call the service manager right away. My G35 has over 250 miles on it, the engine runs smooth as silk at idle or at speed, and I haven't seen a service light. And the burning smell is starting to fade.
IMO, your G needs to be looked at sooner than later. It could be just a minor adjustment, and I would rather err on the safe side.
Good luck.
1. Has anyone ever averaged more than 16 mpg in the mostly city driving on premium gas?
2. What tire pressure do you maintain? The book says 30 psi but I got from dealership set at 38. The ride feels very stiff.
thanks.
Have had my G 3 1/2 weeks and am averaging, according to the info in the NAV, 21.4 mpg in mostly city driving.
The Bridgestones are not a great tire by any means, but they are much quieter and much smoother.
