2007 Infiniti G35 Problems

  • I have a G35x and have had the same problem a few times, but only when it rains for a couple days. I believe it is related to water getting in the controller system. They replaced the controller system once, and that seemed to do the trick, but the problem recurs 1-2x / year and they do not seem to know what to do.

    Does anyone have a suggestion?

    I too have recently had the same problem. I own a 2004 g35 that's had airbag light problems. I went in for the recall back in November of 2010. Now every time it rains they airbag warning light comes on in my car. Mind you I have had NO problems prior to this. Infiniti has now diagnosed the car as needing an entire passenger airbag and module at $875 to replace. I'm not happy about the fact that this car had no problems before this recall was completed, now I'm looking at $875 to replace an airbag and module that should NOT be faulty. The airbag has never been deployed and Infiniti cannot give me a reason as to WHY this has happened. On top of that, the part is on a backorder and may not be here for at least 1-2 weeks. If the part is on backorder, then Infiniti should realize this is a problem with this car and should have included this with the recall. I'm very frustrated!
  • Wow, it's been over a year since my first post on this forum.

    Since my last post I have added a Borla cat-back exhaust system. Crazy expensive, but the music from them and along with the JWT intake is amazing. Guys on hyperbikes even take notice when I drop down a couple of gears and romp on it. Acceleration is much better as well. The power comes on much more linear throughout the RPM range. I also added 4 new rotors and semi-metallic pads. I went with Brake Performance's Premium Slotted and Cross Dimple Drilled rotors. Makes hard braking a sheer joy on the twisty roads up in the Santa Cruz Mountains here in Cali. Lastly, I went with the newer Bridgestone Serenity Turanza's. I went up to the 235/50/17 size and am finding that they are wearing very evenly and slowly thank god. The grip is great in wet or dry and if and when they break loose, the car is very predictable. At around $1,200 for 4 installed and with all the road hazard warranty stuff, they are not cheap but in the long run I suspect good bang for the buck if I can get more than 40k out of them. Still hate the quality of the some of the interior trim.. On my second shift knob and it's starting to dimple and the finish looks like it wants to start peeling. One spoke of my steering wheel is almost void of that wonder rubbery coating and is revealing a shiny gray base.. Hey, maybe I should just strip all of the rubber off, it will blend in with my Liquid Platinum exterior better. :-)

    Still love the baby in general though! Just turned 41k on it!

    Peace, good health, and happiness to all, thanks for listening.

    I hope you get many more years of enjoyment out of your G35. I owned a 2003 model, and it was totaled at 108,000 miles in December - never a single mechanical issue with it. I would have kept it for a long time had it not been totaled because I put nothing but regular maintenance $ into it. Hope you have the same experience!

    HiHoSilver. Sounds like you had a nice G. We still have our 07 G35X. The wife wants to get rid of it. Has right at 13,000 miles right now. If intersted, send me a message.

    Wow I thought this was just me. I think they painted this car with water colors. I have never owned a car that scratches so easy. I know I am reading this several years later, but I wanted to know if you got any resolution to this issue, and if so, how do I resolve my issue?

    Hi, well I agree with your comment on painted w/ water colors!! I first went to a dealer near me and showed them my hood, they said its environmental and would do nothing. I then took it to the dealer where I purchased it and after really complaining about this they did admit there was a problem w/ some paint. The service mgr. got the hood repainted for me and its been better since then. I will not buy another Infinity though because of their cheap paint, never have had another car do this and I have owned Mercedes, BMW, Tahoes, Ford, etc....

    Have you had a luck with paint? I just bought the car with low miles and it was garage kept. I notice new chips or scratches every time I wash it, some go right to the metal. Other show as white, I hope to have a body shop look at it and maybe they can put a heavy wax on it.

    I am driving a 2003 G35. It has been parked in the garage with a full tank of gas for about 4 months with about 30,000 miles on the car. I took it for a drive this morning where the RPM is dropping down to about 600 -650 idling at a traffic light. Normal RPM should be within the range of 700 - 750 RPM. It is as though one of the cylinders is missing. Acceleration is still smooth and responsive. The car has been well cared for and immaculate. Any ideas as to why the car is idling rough when it hasn't even been driven in quite awhile? Thanks in advance.

    It might just need a good long run, with a few good stomps on the gas on freeway entrances. Have you added some fresher gas?
  • Several months ago I had check engine light. According to Infiniti dealer service, the catalytic converter went out. About 1500.00 to replace. I ask the service guy if I didn't fix would there be a problem. He said no. I've had the car since new (it'll be 5 years old in December), and it now has 132,000 miles. At the time I was thinking about getting a new vehicle, so I didn't replace it. I've had no problems with the car since then, and I still have it.
    Should I worry about this in the near future?

    I don't know the answer but, wow, 132K miles in a little over 4 years? You should buy my 2 years old G b/c I usually put less than 15K miles in 2 years. :cry:

    No, unless you live in an area that requires regular emissions testing.

    BTW, bad or marginal O2 sensors (particularly the one(s) in back of the cat) can also lead the OBD-II system to think that the cat is bad.

    Worst case scenario is a fire in the cat. This is usually caused by unburned fuel being dumped into the exhaust, such as can happen during a misfire, stuck injector, that sort of thing.
  • I rather doubt that the diagnosis was correct. If your catalytic converter was non-functioning, your car would run badly and probably catch fire, too.
  • why you crying (a la George Lopez)? no really, it's cool you only have few miles. on the other hand, you've missed precious time with your G (37, right?).
    To be a little more specific, I've driven to Florida several times. Put a couple of grand this year on our New Mexico trip. Truth is, when we travel business or pleasure, I think about renting a car, but blow it off, being so use to driving my car. I've never had a car this long, yet I've never had a car perform so well.
    Thanks to all who answered my inquiry. A further update since my post-after retired for almost 5 years, I decided to go job hunting, and guess where I ended up? At the local Infiniti dealership as a porter in the sales department. And what just happened? My TPM lights up, and I drop it off at the service dept, and go to work. Later I'm told the BCM has gone out, with one of the air fuel sensors. Thank goodness for employee discounts. I was told this was not related to the Cat problem. I talk to the tech, and in all likelyhood, the other sensor would eventually go out as well, although when, he was unsure. Sigh! Anyway, when the right time presents itself, if I see a g/fx that hasn't moved in a couple of months, the dealer will let me buy it at their cost, saving about 2500 bucks. Think I'll wait a while.
  • Hey thanks, I ended up replacing all 6 spark plugs. Car is running great again, just took it on a 1200 mile drive. Unfortunately, the Dealer charged in excess of 500.00 for the plug replacement.
  • Well that's way cheaper than buying a catalytic converter and then finding out that wasn't the problem. Anyway you won't have to do the plugs again for a good long while.
  • Good Day Guys!!
    i have infiniti G35 and at 100k the differential damaged without any reasons. i bought a new one and i replaced it, after that i noticed the cruise control not working well, its only works between 25m/h and 75m/h however when the speed reaches more than 75m/h the cruise control stop, and (SET) which in the meter after 75m/h comes flashing and the cruise control stop working at all unless i have to restart the engine.
    how do I resolve this issue??
    i would be highly appreciated your comments
    regards,
    Bari
  • some problem with a speed sensor or sensor connector, I would guess.
