    Yeah, I'm over on G35 too and I'm still scratching my head at the comments some people are making over there. There's no way I'd go back to the original ECU. *shrug* I know my car isn't any slower, in fact it's faster, because I can launch easier with less risk of VDC activating.

    Aaaaanyway. That's enough dead-horse beating for me.

    I've had my used '07 G35S Auto for a month, and when I finished up a 650 mile trip, I smelled a faint brake smell, even though the last half-hour on the freeway didn't require much use of brakes. After the car was garaged for a half-hour, I went back to grab the last of the luggage, and smelled the same smell, faint, but there.

    The mileage on this trip was nearly 25 at 70-80 mph, so I don't suspect that the parking brake was applied, and I don't rest my left foot anywhere except the dead pedal. Has anyone else experienced this?

    It has been mentioned that some turn off their VDC routinely in order to save on brakes. Is that necessary?
  • scottm123scottm123 Member Posts: 1,501
    Have I experienced the smell... yes.
    Honestly, I just thought it was my driving style (LOL)
    I haven't really given it a thought, but it could very well be the VDC.
    Dunno. :confuse:
  • johninnjjohninnj Member Posts: 243
    I think 2-3 MPG (13-20%) increase in City MPG is a no-brainer trade-off over a car that FEELS faster..but essentially is not. If that heavy tip-in is the result of dumping lots of fuel off idle....I can live without it. Maybe the VDC kicks in much faster on the S models though (I have S Auto). At any rate...I already have the tsb printed and will be doing it next service.

    I've posted concerns about the reflash of the ECU. Brought my 2007 G35X in for service yesterday @7900 miles, mostly about the speed sensitive wipers. When I called to make the app't I talked to the service advisor about the TSBs on the forum. He said that their dealership hadn't done ANY reflashes. When I brought the car in Friday 2/1, I mentioned that the there is an abrupt shift into 3rd gear, worse when cold. The Service Advisor informed me that there was a Reflash of the ECU required per a TSB to correct that. Picked up the car today, the agressive throttle from start is better and the 3rd gear shift is smoother. IThe reflash of the ECU apparently corrected the problem. I did not have any Cruise control issues. So I guess my vote for the Reflash is a Yes !!
  • johninnjjohninnj Member Posts: 243
    I regularly use the paddles to grab a gear earlier (Can you imagine). If I do it in the cold...3rd makes a horrible noise. Mine seems to be fine when left in reg auto mode though...regardless of temp or throttle position. I'd be curious about your mpg (Particularly City) changes (If any) after the flash. I can't imagine the ESC benefit would be very noticeable with one of the X models.
  • adamr001adamr001 Member Posts: 95
    I was under the impression that the smell was related to some type of anti-rust engine coating and it will eventually burn off. I certainly noticed it much more when I first got that car than I do now anyway...
  • scottm123scottm123 Member Posts: 1,501
    We may be talking about two different things here.

    If you drive hard for a while, you will notice a slight (nothing major) smell of worn pads or something.... similar to a clutch smell in a manual.
    I have 12,000 miles now, so it certainly isn't any new engine coating cooking off.
  • adamr001adamr001 Member Posts: 95
    Hmm. This definitely wasn't a clutch smell (I know that smell far too well ^_^ ) but it did stink pretty badly. I only ever noticed it early in ownership when I'd park the car in my single garage.

    The only time I noticed a distinct brake smell was after running my G35 at the race track. I wouldn't have attributed the smell to VDC even though I left it engaged most of my time on the track. I'll see if I can come up with a place to invoke some spirited driving without a lot of brakes required and see if I can smell the brakes.

    P.S. I did eventually pass that Z06 :P
  • scottm123scottm123 Member Posts: 1,501
    LOL!
    Was he re-fueling at the time?

    I've never taken the G to a track day, but every morning that I'm alone and not transporting my kids to school... it's almost the same thing.
    I've smelled this smell occasionally and always assumed it was brakes... although I only usually use them one... when I arrive at my destination! :shades:
  • adamr001adamr001 Member Posts: 95
    [ On Topic ]

    Why would you smell brakes if you only used them once? :confuse:

    [ Off Topic ]
    Nah, the z06 blew a decreasing radius turn :) I didn't.

    Pre turn
    Post turn
    Check out my lead!

    (The reality is the Z06 was BRAND new, still had paper plates on it and the driver wasn't interested in pushing it as hard as I was after blowing that one turn.)

    I have a new G35. Whenever I have a passenger in the car windows fog up to the point I cannot see out...no reason...not snowing or raining..heat not even on window open I have tried everything...it just starts...does not do it if just me in the car.????any clue on this...anyone have this happen...obviously I will take it in but just wondering.
  • scottm123scottm123 Member Posts: 1,501
    I don't have that problem but I know that if the humidity level is just right, fog can set in with numerous people breathing in the car.
    Try making sure that your climate control is set to refresh the air, and that the A/C light is on.
    Yes, it's winter, but the A/C helps to remove excess moisture from the cabin.
  • adamr001adamr001 Member Posts: 95
    There's definitely something about the coating on the glass in the G35 that's sensitive to moister / susceptible to fogging. I've a similar experience, depending on who the second person I add to the car anyway. I just turn the a/c onto defrost and problem goes away.
  • mreynoldsmreynolds Member Posts: 2
    I have a 2007 G35x that makes a odd winding sound while driving. I have noticed that the sound does not appear in the 2 wheel drive model. Just wondering if anyone else has noticed this sound also. Sound did not appear until about 3-4K miles and first did not appear until around 30-40 mph. Supposedly I have the only AWD model in Florida and dealer and Infiniti customer relations are no help. Also, have a whistling squeaking sound coming from the front passenger side of the car when I going anywhere above 85mph.
  • dajatdajat Member Posts: 13
    My 2008 G35x has approximately 3300 miles on it and I have not noted the sound yet. How many miles does your car have on it now? What other types of problems have you had with it?
  • scottm123scottm123 Member Posts: 1,501
    12,000 and change on my X... no winding or whistling noises.
  • mreynoldsmreynolds Member Posts: 2
    Problems I have had with car: Rattle in dash, alignment off causing tires to cup, rear passenger door molding keeps coming loose, rust on trunk where water drains off, grill having black spots. The car has about 7200 miles. The winding sound I here sounds like the car is stuck in 4wheel drive. Does your car sound the same or as quiet as the regular Gs when you drive it, dajat?
  • alang4alang4 Member Posts: 40
    Is it possible that you left the SNOW button in the active position? That's the simplest explanation.
  • scottm123scottm123 Member Posts: 1,501
    Well, even in Snow Mode, AWD becomes RWD over 12 MPH unless needed.
    Snow Mode controls engine output to avoid wheel spin.

    It has to be something else.... :confuse:
  • alang4alang4 Member Posts: 40
    But it still could be noisy.

    I've been in the computer industry for years, and everytime my engineers get stuck on a problem and can't figure it out, even though they're deep into the issue, I always tell them to go back and look at the SIMPLEST thing.....I've got to think the same principle applies here.
  • caspenc213caspenc213 Member Posts: 1
    I've owned my 07 6MT for about 4 weeks now and have just started using the cruise control with ICC and it works great during they day. I haven't experienced the jerkiness of the cruise that others have reported. However, I've noticed that both times I turned on the cruise at night, the display would continually flash the ICC screen and would not allow me to set the cruise. I cycled the cruise on and off several times and same thing occurred. I thought that it could be some interference with the ICC lens up front, but it works fine during daylight hours and I confirmed that there was no obstruction on the lens.
    Has anyone else noticed this problem?
    Could it be linked to whther I have the traction control on or off?
    Thanks
  • johninnjjohninnj Member Posts: 243
    Was it raining? The wipers on anything but delay will override it.
  • adamr001adamr001 Member Posts: 95
    +1 to Johninnj's comment. Also if it's sunset and you're driving into the light, that will cause problems with ICC as well. Of course, you can always just turn ICC off...

    From the manual:
    "To turn on the conventional (fixed speed) cruise control mode, push and hold the MAIN switch for longer than about 1.5 seconds."

    The main switch in this case is the on/off button the steering wheel.

    My wife has been a Camry driver for over 6 years so we thought the G35 would be a step up, wrong. It is very noisy at high speeds, wind and road, had the front struts and bushings replaced and they are making noise again. Car only has 20,000 on it and rattles inside. She is very unhappy after 9 months and looking to trade back to a Camry.
  • zekeman1zekeman1 Member Posts: 422
    A step up from a Camry to G35? Two totally different styles of cars - believe you took a step in the wrong direction - it should have been Camry to Lexus ES350 - that's the step up.

  • adamr001adamr001 Member Posts: 95
    I agree with the other poster... sounds like you didn't realize you were getting a luxury injected sports car. Go to a Lexus or similar vehicle for a sport-injected luxury car and you'd have been a lot happier.

    How did you not notice the wind noise in the test drive? :confuse:

    Although admittedly if my struts were making noise I'd be upset, but I'd be at the stealership complaining too. That didn't work I'd be on the phone with Infiniti Consumer Affairs. So far though, my dealership (one of the few non-stealerships I've been too) has been nothing but professional and helpful.
  • scottm123scottm123 Member Posts: 1,501
    Snow Mode being set "On" or the VDC being set to "Off" are other reasons why the ICC would not set.
    Items that disable ICC:
    Direct sunlight
    Wipers on Lo or High(Intermittent is okay)
    Snow Mode set to On
    VDC set to Off

    Items that will also disable ICC can be:
    Speed drops below 20 MPH
    Sensor becomes dirty
    VDC senses wheel slip and engages
    Engine coolant becomes too high

    Wanted to see if anyone else was having the same problem I am having.

    about 3 mornings ago I awoke to my car alarm going off at around 520am. I ran outside to look for a person, no one was there. I turned off alarm and as I walked back upstairs it sounded again. I moved the car to the garage and then the same thing continued to happen for about 30 more minutes. atleast 10 more alarms.

    took it to dealer they said if they replaces battary in remote it might fix it.

    next day same thing happened in the morning around 520. The Alarm sounded I ran outside... this time I started the car and let it run for a while. Alarm didn't sound again.

    I went back to dealer and they said there could be a frequency in the area that is causing my panic button to sound. They replaced the keys and I guess reconfigured a new frequency.

    This morning... again after getting the car fixed yesterday. Same thing happened at 5:24am. Alarm went off 1 time. I stood by the car outside for 15 minutes to see if it would go off again.. it did not.

    I called the dealer they said they have never seen anything like this. Any input from anyone would be great.

    I find it hard to believe that there could be a signal that made it through the first switch, i guess this is assuming they actually changed the frequency and didn't just switch out the keys.

    Thanks.

    I found this thread: Toyota Highlander 2008 #2295-Re: Disabling Factory Alarm

    It sounds like this car is having similar problem. It's having some kind of signal
    interference with electronic product such as router,portable GPS/Navigation etc..

    Good luck. :)
  • dajatdajat Member Posts: 13
    My car just passed 5770 miles. The only notable problem is that 3 times my gas cap could not be removed. The third time (this afternoon) it came apart leaving a portion sealing the top of the filler tube. I have a quarter tank left. If the dealership does not resolve the issue tomorrow, I'll be on fumes before Sunday night. An unenviable position to be in with a G35x.

    Beyond the gas cap problem, there has been nothing noteworthy to report. I have noticed a fair amount of water collecting around the trunk when it is washed or raining. I dry mine out frequently if it rains or the vehicle is washed.
  • g35jong35jon Member Posts: 5
    Anybody else have this problem?
    Air bag warning indiator light stays on after start up (2005 G35 with 22,000 miles). Dealership replaces a circuit board when this happens but problem just reappears.This problem has been "fixed" 3 times already in last 18 months. Clearly there is a manufacturer's defect my dealership has failed to remedy. My wife is afraid to drive the car with electronic /air bag defects and dealship tells they will only do what the manufacturer (Infiniti) let's them. A 2nd dealship agreed to attempt fix number 4 while car is still under warranty.
    PLEASE HELP ME -I I HAVE A :lemon:
  • dajatdajat Member Posts: 13
    Is there another dealership available which could offer a fresh view at the problem? I don't know anything about this particular system, but strictly from a troubleshooting point of view, if a "known good" replacement part keeps failing after being replaced, it strongly suggests, some input or output to the card is out of tolerance to the point where it kills each replacement card shortly after it is installed. There is also the possibility they have known quality problem with that card and are simply coming across a few bad ones from the same lot, that said, I believe the former is more likely to be the case.
  • dajatdajat Member Posts: 13
    Here is an update to the gas cap issue.
    The dealership replaced the cap with a new one. So far, so good.
  • g35jong35jon Member Posts: 5
    dajat - thanks for your reply. You input is helpful. Original dealership has replaced same card three times, and a different part on another occasion. They informed me this is all they can do and that my problem is with the manufacturer. ( true enough, but so much for the "Infiniti customer experience" ) Scheduled appointment at a different dealership Monday for the next fix. This will actually the fifth attempt in two years at a remedy.
    I love this G35, awesome design, but failure again means hiring someone to represent my case before the manufacturer.

    Hello, I'm not technical at all so thought I'd reach out for some advice from fellow G35 drivers. Have 2007 G35 Sport and find when I do a hard acceleration in 2nd or 3rd gear (not sure which), on occasion the engine races to almost 6k RPM and then the transmission seems to engage. Otherwise rides like a dream. Any thoughts or advice?

    Thanks in advance
  • deedubyadeedubya Member Posts: 2
    Hello have a 2007 G35 Sport which is a big investment for me. Want to keep it nice and clean, have a good cover but also would like advice from users on the best products to use to (1) Clean inside dash (2) leather (3) wheels (4) wax body. The manual says ask the dealer but they dont have a clue.

    Thanks in advance and happy safe riding to all
  • coolguy8157coolguy8157 Member Posts: 29
    For leather I use Lexol.... and for the exterior DuraGloss PBA and TPP products.... :)
  • g35nyg35ny Member Posts: 1
    Hi pmonica - Did you ever figure out why this was happening? The EXACT same thing just started happening to me three days ago with my 2007 G35x (all package options). The alarm has gone off on its own three nights in a row around 10:30 PM.

    The only thing I can point to as a possible cause is I've kept it in the garage all winter and it started happening the night I left it out in the driveway for the first time. It didn't get very cold or anything, so I'm not sure why that would matter. As a test, I left it in the garage tonight and, sure enough, the alarm went off at 10:30 PM, almost right on schedule for the previous nights.

    I haven't called the dealer yet as I've been busy with work, but if you found a solution, please let me know.
  • sebuulbasebuulba Member Posts: 3
    You guys are all like a Godsend! I've been having this problem in my 2005 6MT G35 sedan for 7 months now. They have replaced the throttle body, clutch, ECU, PCM, made me buy new tires, blamed the gas, changed the speed sensors in the wheels and the dash......the car still does the exact same thing!!!!!! I'm dealing with the BBB now trying to make them buy the car back since they can't fix it. The kicker is that they claim the car does not do what we all describe. They say it is driver error....LOL. The car has been into the dealer over 9 times and the corporate engineer has even had to come down. Even he claims the car is not doing anything wrong. No car I've ever had has done this crap before. Anyone know what the problem really is?
  • sebuulbasebuulba Member Posts: 3
    I'm in Houston too! Which dealer are you going to? I went to North Houston Infiniti and they did absolutely nothing to actually fix the problem...just change out parts for nothing.
  • sebuulbasebuulba Member Posts: 3
    I have same problem! I have found that going through the Better Business Bureau has helped the most so far. Also, there is actually a link on You Tube for a guy who has a Skyline that has the same problem. He Dynos the car so you can see exactly what is happening. Just look up G35 Problem and it will be there.
  • esfoadesfoad Member Posts: 210
    I had the airbag light come on as well. My car is an 05 G35X. My dealer did not replace the circuit board. They said thay tried that with another car and it did not fix the problem. Instead they replaced a cable in the column. Some kind of curly cable. Sorry for not knowing the exact name. Anyway, the problem never returned. Dealer is Salerno-Duane Infiniti, Denville, NJ in case your dealer wants to check.

    Over the past 11-months since reading this forum and owning this vehicle, I have seen some other postings regarding paint chipping, so apparently this condition has occurred with others. Does anybody know at what point paint chipping can be considered a product flaw (and covered under the warranty) versus 'caused by owner' and not covered under warranty?

    My situation...I have two sections of the car where I have small paint chips (no dents). One side I suspect might be from my wife's rear driver-side door. She parks in the garage on the right side on my G35. She gets out of the car and then opens the back door to get her stuff out. She has always been careful when opening the door, and admits that the door does touch and rests against my passenger-side rear door, but she never has opened it hard and banged the doors together (I believe her, and as mentioned previously, there is no actual denting).

    Then on my driver door, I open it and sometimes depending how close I parked, the door might open and rest against the rounded edge of my lawnmower handle. Again, no hard slamming and no dents. Unfortunately I have to assume these small paint chips were caused by this door just resting against the lawnmower handle. As I mentioned, the lawnmower handle is curved and rounded; not sharp edged or pointed.

    Now I can easily see how one might say the chipping was my (and my wife's) own doing. But I am stumped, as have others that have encountered the chips, that this was so easily caused by the above-mentioned actions. It would seem to me that a good paint job would be able to protect and retain itself better than this.

    One last point...I had the paint coated with that paint shield stuff, done by the dealership, when the car was bought brand new

    Any comments? Suggestions?
  • carnaughtcarnaught Member Posts: 3,576
    Any comments? Suggestions?

    Buy touch up paint and move the lawnmower.

    Seriously though, I have not noticed any more paint chipping problems with the Infiniti compared to any other car.
  • g35jong35jon Member Posts: 5
    Appreciate the reply Esfoad. After dealer where I bought car replaced the board four times, I went to a different dealership. The second dealership replaced the cable you mentioned, as well as the board and the whole driver's side air bag. So far so good after one month.
  • esfoadesfoad Member Posts: 210
    That's great! Let's hope the problem is gone. My light has not come back on so I know the problem was fixed.
  • bfdm316bfdm316 Member Posts: 2
    I have a 2007 G35 and would like to find out a way to disable the video safety feature. This is the feature the requires the e brake to be engaged in order to play videos on the media screen. Does anyone know how to do this? I have been told it is a fairly easy procedure but am not all the inclined when it comes to things like this. Would doing this void anything on the car? Please let me know if you can help, thanks.
  • alanrosemanalanroseman Member Posts: 23
    Hi,

    If anyone responds to this please let me know. I'd like to do the same thing. I've been told it is VERY difficult to accomplish.

    Alan Roseman
  • blnewtoblnewto Member Posts: 146
    Haven't tried it but maybe just presing the e-brake down until it first catches would be enough to watch videos without effectively applying any braking to the pads?
