2007 Infiniti G35 Problems

poorchemist

Thanks for the heads up. I am taking the car in again next Monday and I will tell them to look at that too.

:sick: I have also had this problem. Have taken it in several times for this problem. Was told the last time that Infiniti is aware of the problem but has no clue how to fix it, so there is nothing the dealership can do for me. Filed a complaint directly with Infiniti on 11/21/07 and have not heard back from them. Worst customer service.

Hey guys...

When you exchanged the key fob for the new ones, did they copy the seat/mirror memory settings into the new key fob as well?

Anyone have the problem of the gas pump clicking off constantly throughout the fillup? Now given the fact that I pumped gas for a living in Jersey(No Self Serve) from age 16-18 I know it can't be my "technique" as I have substantial experience in the area at hand. I'm taking it in today to get evaluated, can be quite annoying to deal with having it click off 15x a fillup.

I had this problem at one specific gas station. Moving to another (same brand of gasoline, different pumps) station resolved the issue.

I have had a problem with an 07 g35x. Brought to two dealers three times and still coolant leaking. Will bring next week again. Service manage swears on a stack of bibles this has never happened before...

kadary

Can the dealer really fix the snappy start of the accelerator? My wife takes my car occasionally and comments regarding the snappy acceleration with just a touch of the pedal. :surprise:

kadary

Switched em on over no difference at all.

This TSB for cruise control has a definite impact on the way the throttle works. See my other posts in various threads about it.

vik_kid

This has happened a few times with me too, and though I've not figured exactly why(scientifically) it happens, I am assuming it has nothing to do with the car itself... I say so because it ONLY happens at "particular" gas pumps. As soon as I change from one pump to another(in the same gas station), it works like a dream.
The only logical explanation that I can think of is that there it is something to do with the pressure that the nozzle( of the gas pump) is offered- the same mechanism that ensures the pump cuts off when the tank is full(?)... and maybe different pumps have a different pressure thresholds...... so i would think this shouldnt be much of an issue with the car itself...

miamishaps

So got the car back after I dropped it off and they said the valve was "clearly" faulty. The gas pumps typically click off when the vapor pressure gets too high which should mean the tank is getting full.

As far as mine went, it would be any gas station any pump every time.

Hopefully the problem is fixed, now I just need the front driver side mat replaced and we should be good to go,

from my head snapping back every time I want to get of the stop.
Can't really control gas pedal, which is too sensitive. I became to hate the car for this reason so much that I am getting rid of it.

You know, you could just read a few posts above, and realize there is a TSB that addresses the snappy throttle. Adam in particular has commented on this extensively.

Plus, curiously, back on Nov 20th you posted a similar comment about the throttle (message #308) and stated you sold your G35x. You mentioned you now have a "G350" (sic) and it drives like a dream. Are you sure your not still dreaming about the G35x? :P

I wish, there would be an option given of smooth acceleration. Snappy trottle drives me crazy, mainly in low speeds or at stop and go. I start to hate the car even thow I like everything else about it.
I took the car to the shop a few times already to be told, that it is normal. If it's normal, I will get rid off the car! I don't think it is!

pat

Actually, as another member just pointed out, we're confused. You said here you'd already gotten rid of it: lazer, "2007 Infiniti G35 Problems" #308, 25 Nov 2007 7:34 pm.

Do you still have the G35? There is help for this problem that you'll find by reviewing the previous posts.

g35flooded

I noticed earlier this week that this light the (!) is lit when the car is on. Does anyone know what could be the issue ? I only have 1800 miles on it so I can't see it being the oil or washer fluid since I barely used it. Any ideas?

adamr001

Here's a pic with the light on in my 6MT -> http://www.tall-tales-racing.com/img/cars/g35/images/09.steeringwheel.jpg

See the two buttons in the top right area of the picture? One is a square, the other's a circle. Pressing the square will cycle through your display screen to get to the warning screen and it will tell you what's going on. "!"s are non-critical items. Low on fuel, tire pressure slightly low, door open, trunk open, etc.

g35flooded

^Thanks.. I'll check when I get home from work. I checked my doors and trunk last night but still had the same issue. Maybe it's the tire pressure... As long as it's nothing serious I don't really mind but i def. want to know what's goin on...

It takes about 10 minutes for my heated seats to get hot. On my old car, they were hot in about 2 minutes.

Anybody else have this problem?

scottm123

When was the car built?
There's a TSB for the heated seat wiring harness... for seats not warming correctly, or not getting warm enough in one section vs another

Heated Seat TSB

cfg1

Thank you. They already replaced the wiring harness. Before that the seat didn't get hot enough, only slightly warm.

Now they eventually get hot, but it takes a long time. Do yours take a long time to heat up compared to other cars?

adamr001

If I run mine on High, I'm turning them to low inside of the 5 minute mark and turning them off entirely inside of 10 minutes.

houston35

Darryl - Was the dealer able to solve the hesitation problem? I am finally bringing it in to my dealer in Houston next week. Any advice appreciated. Bruce

jburlowski

Since you keep posting slight variations on this same message over and over, m'thinks you are just here to trash / sow discontent about Infiniti / G35.

What is your real motive?

carnaught

Snappy trottle drives me crazy, mainly in low speeds or at stop and go. I start to hate the car even thow I like everything else about it.

Hmmm....I don't have the problem; that's all I know.

scottm123

I'd call the throttle "responsive"... Not snappy.
I've gotten used to it. If someone can't, then try the '08 ECU flash.

almatti

Now that the weather has turned so colder, as to warrant using the heated seats, Yes I find that that they seem to take a longer time than other cars to heat up, even on High setting. My 2007 Honda CRV heats more quickly than the G35X.

For my next Infiniti Service, I will submit to have checked.

jebell

I have a 08 G35X and the heated seats take a long time to warm up and then are only "warm". On my beemer and lexus the seats get hot fast. This annoys my wife more than me but would the wiring harness replace help this?

zekeman1

I doubt it. Last week I mentioned the time it took to my dealer; he said there was a TSB out covering heated seats but it was for those which did not heat at all. He said these take longer than (some) other cars. Tell your wife to look forward to summer

Has anyone run into a wheel alignment problem with this unit?

My problem- Bought the coupe new and after only 18,000 miles had to replace all tires
due to bad camber (Cost +$900). I had the vehicle maintained every 5K miles, at the Dealer, without any comments related to bad alignment. After I replaced the tires I took the vehicle into the dealer to have it aligned and to discuss this problem with the Service Manager. After paying another +$100 for this service I was informed the "All
G35's have a problem with alignment and that they could be aligned every week
and still have this problem. FACT OR FICTION??

My conclusion: If this is fact then a "High Performance" vehicle like the G35 is seriously flawed and has a safety problem.

Any comments or confirmation would be appreciated.

desidogg

Well I dont have any problems with alignment with my 07 G35, but as it is a differnt vehicle it doesnt mean much.

But i wanted to comment about your tires, the tread life on my bridgestone tires is only 20k miles, so you may not lost as much as you think you did. When I replaced them, I put in goodyear eagles which have a 40k tread life.

gooddeal2

I used to have an '05 coupe. When I traded it in at around 17K miles, tires still had about 50% tread left...never had any alignment problems during the 2 years I owned the car.

turborod

I have read a number of posts about the snappy thottle response upon takeoff. An up grade to the 08 program was implied by some of the writers. There may of even been a claim for better gas mileage around town. In any case while having my oil changed recently at my dealer in S. Jersey, I asked the service manager about any recall or service bulletin about this problem. He claims there is none and if you tried to put an 08 program into an 07 computer, their equipment would not allow it.

My question where are folks getting this done and under what program. If anyone has specific information as to bulletin # etc. I would be interested in hearing about. Frankly the problem does not bother me most of the time and I would only have it done if there was no change in full thottle performance and there is evidence of somewhat better gas mileage.

Infiniti TSB for Surging Cruise Control

That's the appropriate TSB and it includes an updated (though not 08) reflash of the ECU.

*edit* This was a night and day improvement in the car for me. I received notably improved in-town gas milage. You can look in other portions of this forum for my posts on the subject. Just search my username.

zekeman1

I had the update outlined in the TSB on my 07 G35X - fixed the problem for me as well.

turborod

Thanks for your input on this subject. I don't know whether I have any problem with surging cruise control. I will have to check it out. Also I don't know whether the VIN numbers listed in the TSB fall under my own car. I am presently getting 21 miles per gallon with the car in the winter weather of S. Jersey being driven by my wife back and forth to school about 8 miles each way.. no highway mileage to speak of during this winter period. I may not improve much on this figure with any upgrade.

adamr001

Yeah, if you're hitting 20+ with commuting and winter fuel mix you're doing pretty good!

trh65

I have also have this problem. First they said no one else is having this problem then they said Infiniti is aware of the problem, but doesn't know how to fix it. I have contacted Infiniti directly and have had no luck. This is by far the worst car I have ever owned.

adamr001

The only delay I've ever experienced in my 6MT was caused by VDC turning on. This used to happen to me fairly frequently, but I took my car in for the Cruise Control Surging TSB and that resolved the issue.

The reason it resolved the issue, so I understand, is that the acceleration input curve (to make up a term) was FAR too aggressive by throttle position on the default ECU program when the throttle was between 0 and 50% depressed. This caused the rear tires to slip which in turn activated VDC.

Try this simple test. Turn OFF VDC. Try to accelerate. If you do with no lag, you are, most likely, experiencing exactly what I was experiencing. If you still have lag, then you have another issue and it might be time to fly the yellow :lemon: flag. Just call Infiniti and tell them that you think you have a lemon and that you're going to contact your state government to get started on the lemon-law consumer protection process and they should jump to help you.

jennma

I have noticed the VDC light coming on when accelerating at about 40 - 50 mph going up a slight incline which is not curved in any way and dry conditions on a few occasions (most often noticed on the same road, in similiar area, but other times too). That was definitely an odd one, especially because I was not overly aggressive with my acceleration in those conditions. I can't remember exactly, RPMs were probably not much higher than 3000-3500 RPM in 5th.

Of course other times it has come on as expected when I'm skating along the local roads in icy snow conditions. :P Since I have to take the car to the dealer for the voluntary clutch adjustment in the next few weeks, I'll ask them to take a look at that point and see if correcting the Cruise Control Surging TSB helps the problem. Using cruise control is something I never do, so I won't have noticed that issue.

infinitiuser

I test drove 5 of those since late '07 and had the same pleasant experience of a peppy, jumpy and muscular acceleration from the get go. the one I bought less than 2 weeks ago feels quite different. I don't know whether it is defect somewhere in the controls or something else (like an intended change) but my '08 does feel different without a doubt. It's sluggish and revs up high before getting much speed. It's not the same agile car. I also feel the steering a bit heavy and the breaking somewhat less strong. I pay lots of attention to detail and I know there is something there.

Has anyone experienced something similar?

Also, some wind noise (hissing) starting around mph.

smokey75

Release the parking brake, put some air in the tires, & roll the windows up all the way. :P

scottm123

Currently, there is a TSB out for the '07 G35 which is supposed to take care of an ICC issue, where the car surges a little while rolling downhill.
This TSB includes flashing the ECU with the '08 G35 program.

What this does is it calms down the acceleration from takeoff. A lot of owners complained about the G being too aggressive off the line and this 08 ECU reflash certainly addressed that issue.

A lot of people ran out and immediately had the TSB performed on their 07's and they are now sorry they did so. They wish to have that aggressive edge back. Some have asked the dealer to reflash it back to the 07 and they have been declined.
I also was on the fence and have recently decided to not have this TSB done.

The reason you didn't feel it in test drives and you do now is because this particular ECU was not immediately included in the first production 08's... so the 08 you tested may not have had this. Sounds like your car has this update.

Where are you getting this info from? Just curious as this is the first I've heard of people asking to get reflashed with the old ecm.

scottm123

I spend a fair amount of time on G35driver.com

infinitiuser

Thanks very much for the info. It is a decent explanation and one that is likely given what I observed. I took the car for diagnostics and all was normal. The service folks did inform me though that they can do something to make it 'pick up speed faster'; i.e. in physical terms accelerate stronger. They said they could do this 'anytime I wanted'. I declined for the time being. After driving a loaner for a day I got my fill of the jumpy acceleration and found it annoying (for my taste) and at times dangerous in stop-and-go traffic conditions. I was more concerned about a defect but now it seems like something 'intended' and which apparently, at least in this particular dealership, can be undone. Good to know. (dealership in Monrovia, CA).

One potential difference between the TSB you mention and their claim at the dealership is that they said they could make the car 'pick up faster in the freeway' which may imply no change in the acceleration from rest but while the car is already moving. It may very well be the same thing. Perhaps you saw something about this in the site you mention?

I appreciate your dilligence and you sharing these goodies with us.

Cheers

scottm123

Although the TSB includes the replacement of the ICC sensor, it's the ECU reflash that makes the difference in acceleration. It's possible that your dealer is only referring to this ECU flash... but we're guessing. I love how they give you only part of the story, and never all the facts. It's OUR car!!! Ugh.
Anyway, I've gotten used to the ridiculous neck snapping starts and actually handle it well now. I can start off without any silly lurches forward but I do find this MUCH easier when in M mode than when I'm in D mode. The D mode has a mind of it's own, and with this quick accel issue... it can see where it would be dangerous for some.

Also, having an X model, I have the luxury of going into Snow Mode. This cuts the power to the acceleration down quite a bit, and these lurches never happen in Snow Mode.
In fact, I've had the car in Snow Mode for weeks now, with all the crappy weather we've had lately. I just turned it off this past weekend and had to learn how to drive the car with all that power all over again. :P

jl114

I bought my car in to replace the ICC and get reflash done. Dealership said they needed a day so they lent me a loaner car, which was an 08. I also felt that the acceleration sluggish and the car felt slower. Gas pedal felt much more stiff, so I suppose no more accidental lurches, but I prefer the 07. Steering felt weaker actually, on a bumpy road I take weekly, it didn't feel as heavy as I liked. On the other hand, braking was smoother than the 07.

almatti

I have a 2007 G35X with Auto. I 've been reading all of this about the REFLASH of the ECU per the TSB. Don't have the Cruise Control issue, but I don't have ICC with my car. There's enough Bells & Whistles already.... I will admit there is Jumpy throttle at take off from standing start (felt it on the test drives - it caught my attention when I first stepped on the gas at the Dealer who didn't warn me....took off like a rocket !!) . It takes a bit of practice to control it. I've been tempted to administer the Reflash, but reaing Scott's and jl114's comments here, I might skip it. I too am a member of G35 Driver Forum; I think I've "seen" Scott there about this same issue. Call mea glutten for punishment, but I like feelin' the "G" force. That's I bought the car.....
