Infiniti G35x

patpat Posts: 10,421
Here's a place you can talk specifically about your G35x - or the one that you'd like to be yours! ;) Since the 07 G35x utilizes a unique combination of new engine, chassis and AWD, it seems like it deserves its own discussion.

Enjoy!

    Been driving my '07 G35x, it's pretty nice, feels/sounds like a race car, but...

    My question - what RPMs does yours run at at 60 or 70? For instance, mine runs 3,000RPMs @ 70mph, which to me seems preposterous, as if it's running in 3rd or 4th gear.

    I want to know if these all do this, or is my car broken?

    Thanks all!

  • My G35 6MT coupe is in the shop for a headlight recall and they gave me a brand new 2007 G35x loaner. What an improvement over the old G sedan! It is very nice. Just my quick two cents:

    The looks are so much better. Both in and out.

    The interior has really improved over the older model, but I am not sure if I like the styling any more.

    The ride seems much smoother. But that may just be the tires.

    The shift points on the auto were a little off for me, but I am sure the car adapts to the driver/conditions.

    Unfortunately, my right leg rubs on the bulging center console in all the wrong ways and I still cannot get the driver seat set "just right".

    Also, I think maybe the center console and dash may overwhelm the feeling of the interior. The car feels smaller.

    But:

    AWD, Leather, 300 horse v6, decent stereo, power everything, key fob/keyless ignition, and too much more to list... all at a great price point no one else can touch.

    Maybe when i get ready to trade in my Coupe next year the G35 sedan will be on my list of cars to test drive.

    I think he'd like to hear from other G35x owners as well. ;)

    You mean other opinions count as well?
    ;)

    hehe. Yes, the msg was kind of moved to the "G35x" forum, the X being a separate beast from the Coupe/Sport, with its 306HP/AWD combo...

    Love the car of course, just wish it had a "granny" switch so I could actually get > 20mpg sometimes :)

    These cars have the VQ35HR. Infiniti say's the HR stands for High Rev and High Responsiveness. This engine is low friction, high reving and smooth so driving at 70 at 3,000 RPM is effortless; we just aren't used to seeing those RPM's. What are the 6 MT's turning at 70?
  • patpat Posts: 10,421
  • ddnyddny Posts: 20
    Yes, smooth is the word. My first inclination was to because it's so different drivetrain-wise from my quietly speedy Accord V6.

    After taking a few spins over the weekend, I now conclude that the problem exists in the driver's seat (me). The thing is just damn awesome, and sounds like a race car when properly wound out... :shades:

    How about the downshifts? Coming into a turn at 60, drop it to second and the sound is AMAZING! then push it out of the turn and "swell" back to 7500 and it blows you away.

    This car's is an absolute thrill to drive, especially when you keep it in the sweet spot of 4500-7000 RPM.

    Thanks, Mr. "my car's already broken in" :mad:
    (LOL)
    I try to keep it below 4k, but I'll admit, I cheat sometimes. :blush:

    For all of you that already own a 35x, what was the pricing that you recieved on it...i currently am trying to haggle for 36 even w/o taxes, on a black on black, navi, prem and wood trim. Any pointers on how low I should try to go before i give in?...I am residing in the North Jersey area.
  • dafinmandafinman Posts: 8
    I'm in Oklahoma my dealer had a large stock of Sedans and the one I wanted on the lot. They knocked 1.5 K off the price but I also added $700 for the urethane film and had XM added so there was some fluff for them to work with. BTW, mine does not have Nav.

    I was looking for an X in Houston and they don't stock them because of the mild weather. The RWD stock was very low because they are in such demand so they were not dealing at all.
  • ddnyddny Posts: 20
    Yes, the tailpipe growl is awesome, more like a small 8 cyl. I'm a big chicken, so since mine's still only at 1200 miles, I'll wait until 3-4K miles before purposely redlining it :)
  • ddnyddny Posts: 20
    I did the lease thing, $359/(24)month @ 12k miles for , 3800 down, $25K residual, it was a national deal for the X w/sunroof+splashguards, wish I tried to swap the sunroof for the convenience pkg (nav/blutooth), only about $1K difference. The residual seems reasonable, for a car that keeps its value pretty well.

    Hey Guys -- is the G35x as tail happy as the RWD counterpart?

    I test drove the RWD and I easily had the tail come out on a sharp right turn.. but I dont recall being able to do that on the X version..or maybe I just didnt drive it hard enough..hmmm...

    I have yet to see that for myself when I get my G35x in 3 weeks time.. Im very excited!!

    Hi all,
    New to this forum but already have learned quite a bit so thank you!

    I got a new 07 G35x AT yesterday but have noticed something when hard accelerating: when the car is shifting from first to second, the dash lights up a "Wheel Slip" light and the engine cuts power momentarily, then resumes. Of course the roads have been perfectly dry....

    This has happened on the test car I drove, my car and my friend's car.

    This doesn't happen when I change the gears manually via the "manu-matic" shifter.

    I searched the forums but didn't seem to come across this exact same issue - anyone else experiencing this and/or know about it?

    Thanks and regards!

    VDC. (Vehicle Dynamic Control)

    Your car is sensing wheel slippage and it's cutting engine power to regain control.
    You can either calm down a little or turn the VDC off. There's a switch near your left knee.

    More importantly is is that you have a brand new G35 which is a day old and your already flooring it?
    Read the manual and the break-in schedule.

    There should be no hard acceleration or braking, and no holding RPMs for a long time in any one position, like highway driving for at least 1,200 miles.

    Calm down! Your G will thank you.
  • ripmasterripmaster Posts: 11
    Hi Scottm123,
    Thanks for the reply. Yup, I get that that the car is sensing slippage...but the fact is, there is none... it's my opinion this is a small problem with the G35X automatic transmission...as I said, it's happened in 3 different cars, all on perfectly dry, debris-free roads. The problem does not happen when shifting gears manually (from first to second at least, I have not gone full throttle from second to third).

    On another note, please don't think that all I'm doing is driving with my right foot planted all the time :blush: ...I know the break-in guidelines for this car and have owned many other new cars as well, but I can tell you that a VERY infrequent full run from first to second will not harm the engine in any way.

    Matter of fact, it was the salesman himself who first noticed this "anomoly" when he drove a demo car off the lot and I was in the passenger seat and he was showing off the acceleration. My friend was on that test drive and when he got his own he noticed the exact same behavior...

    So anyway, back to the original intent of my post: do you think this could be a true quirk for these cars?

    Promise my G35X will be just fine too! ;)
  • scottm123scottm123 Posts: 1,501
    There IS slippage.
    The reason you do not feel it is because the VDC is doing just what it was designed to do.
    You'll also notice it if you're doing about 30 in the right lane, floor it and change lanes. As the wheels are under that torque and hit the little painted lines in the road, the VDC will flash.
    The wheels are not full-on slipping because the VDC is doing what it's supposed to do.

    There is no quirk with the tranny.

    Turn your VDC off and test again.
    After 1,200 miles, of course. ;)
  • ripmasterripmaster Posts: 11
    Hi Scottm123,

    Well...I really hate to seem argumentative here, but remember that the problem does NOT occur if I manually shift from first to second; it's only when in automatic mode... :confuse:

    In manual mode the car just keeps on going full bore through the gear change but in auto mode the engine cuts power for a full 2 seconds or so right as it is about to change into second (as you point out, the VDC is kicking in)...

    I know I won't be trying this again anytime soon so for those that have passed the engine break-in period, I'm wondering if you continue to experience the same thing?

    I know that in the demo car we rode in, it had about 4000 miles on it and did the same thing. When I shifted that car manually from first into second, - no VDC engagement at all. I guess we need some field testing ;)
  • scottm123scottm123 Posts: 1,501
    Dude... no arguing at all.
    These back-and-forth discussions are how we come to conclusions.
    I think they're kinda fun, actually!

    Anywho... I may have misunderstood you.
    What you are saying is that as the car is about to shift from 1st to 2nd, there is a pause in acceleration and the VDC light blinks?
    NO... I don't experience that, or at least, haven't noticed it.
    I do spend most of my time in "M" mode though.
    Sounds like a fun test though, so I'll try it out tonight and let you know what I see.

    I have an 07 G35x with 3,700 miles on it.
    It's solid in "D", "DS" and "M" mode and there is no slipping of any kind in any gear change.

    Like I said, I only see the VDC light flash if I rocket around an intersection corner, launch from those slippery toll booth platforms, or do a little bump drafting and then pass at full throttle.
    So yes, I do see the VDC light once in a while when I'm driving hard, but I would definitely not caulk it up to "tranny slipping" :confuse:

    With all that being said, I will say that "DS" and "M" modes offer a much more efficient gear change than "D" mode, which I believe is designed to be a little smoother.
    This, along with whatever adaptive learning the "D" mode has picked up, may have something to do with it as well.

    This is actually one of the more impressive transmissions I have seen in recent years.
    If the X offered a stick, I would have been all over that... but for an Auto, I couldn't ask for anything more.
  • ripmasterripmaster Posts: 11
    Hey Scott,
    I agree comeletely about this line of discussion; it's kept positive and mature so I am very appreciative!

    So yeah; the VDC pause also happened in "DS" mode too...
    I'll keep monitoring this thread for your input.

    As for this AT; I agree it is one of the best out there!!!
    By the way, I've read about people experiencing jerky take off from a stop; I don't experience this at all!
  • scottm123scottm123 Posts: 1,501
    Jerky takeoffs...
    The adaptive learning of this tranny is critical for it to be smooth on takeoff.
    When I bought my car, it had 10.5 miles on it.
    Even when feathering the throttle with the slightest touch, the car took off like a damn rocket.
    Drove the wife crazy, because she thought I was driving like a nut job.
    Got to the point where I thought about carrying a neck brace for passengers. :P

    It has since calmed down and it's now smooth as butter, but still rockets off if I want it to.

    I'll test for the VDC light tonight and will post my findings tomorrow morning.
    I'm going to be in my office until about 8 tonight, so the roads will be nice and empty for my commute home.
    Any test which consists of WOT is a good test, in my opinion.
  • ripmasterripmaster Posts: 11
    OK Scott, I'm home but confirmed that it happened with my friend's car again. He's anxious to see how widespread this is...

    Not a huge deal but it shouldn't happen...still in love with the car though! :D
  • scottm123scottm123 Posts: 1,501
    It was pouring out when I left the office last night.
    Takeoff has been postponed due to weather conditions. ;)
  • ripmasterripmaster Posts: 11
    Hey Scott,
    Too bad! I live in Colorado so I should experience just about every kind of driving condition at one point or another, but the AWD in heavy rain should be interesting :P

    By the way, a BMW 335i pulled up along side me at a light this morning...GAWD I was tempted but restrained! Go figure :surprise:
    He took off and man does that car appear to be fast!

    On another note, I opened my sunroof yesterday and the molding on the right side just spilled out :cry:

    I know there is already a service bulletin about that so back to the dealer I go this weekend. Hopefully not the beginning of a pattern!

    I also went out and bought a Garmin Nuvi 660 to use in the G...anyone here have any experience with that unit?
  • scottm123scottm123 Posts: 1,501
    The service bulletin for the moonroof liner was taken care of on my car this past weekend while getting the oil changed.
    Quick fix.

    If that's the worst to come, I'm very happy.
  • scottm123scottm123 Posts: 1,501
    Okay, I had the chance to make a few runs this weekend and yes, the "Slip" light does blink... but it happens in "M" mode as well and not just in "D" & "DS".
    Don't see it in "M" mode?
    Turn out, left or right, onto a road and nail it... you'll see it, no matter what mode you're in.

    From the manual:
    Slip Indicator Light.

    This indicator will blink when the VDC
    system or the traction control system is
    operating, thus alerting the driver to the
    fact that the road surface is slippery and
    the vehicle is nearing its traction limits.


    This is what I was trying to explain.
    It's not your transmission slipping, it's just the VDC kicking in to keep you glued to the road.
  • ripmasterripmaster Posts: 11
    Hey Scott, -
    Thanks for testing this out...did you get the engine cutting power for a couple of seconds too? Hmmm, so you had it happen in M mode too? Read on for some interesting news:

    Turns out when I was getting the sunroof molding fixed, my Infiniti service manager knew about this "occurance".

    He claims they are amassing more data but that in essence there is apparently a pressure sensor in the transmission that may be programmed incorrectly. He would not confirm this in full but we all may need to "stay tuned" to see if this becomes an update. I asked him if this is occurring on the G35 (non-X models) and he hasn't heard of any reports...the plot thickens!

    Well, I've owned many cars including an M3, Audi Turbo A4, Eclipse Turbo and none of them ever cut power when accelerating from first into second like this. Not a huge deal, but one I would like to see corrected if it is indeed an issue...just love this car though!

    Thanks again for testing Scott. Oh, and I knew the transmission itself was not slipping, I just thought it odd on a perfectly dry road in a straight line the car would detect slippage of the tires on the road and cut power...
