cold start problems

^No, I highly doubt any of that. It's pretty clear this is some sort of strange issue with '06's. Other years have had this issue, and replacing the battery fixed it just fine.

I wouldn't blow another ~$80 on a battery.

As soon as you turn the key, I can hear that the battery is not good enough. Okay, you changed your battery a year ago...maybe you just got a bad one or something happened....get a new battery first...it doesn't sound right when you turn the key almost like you had left the lights on too long.

Or maybe there is some sort of electrical leak where it's using the battery when you don't want it too. If you did ANY electrical mods, I would wonder. Something stupid as simple like new HID fog lights maybe could be draining all the time or more than you think. Just saying.

I agree with stu. I doubt that it's the batteries. And the only "mod" I have is the HID fogs and I've had this issue even before I put them in so obviously that's not the problem here. And if you're correct (that something is wrong with the electricals) then infiniti has made some errors with the electrical of the 06 fxs.

I wouldn't say if the fogs could be causing it that Infiniti has some errors with electrical. Let me give an example. Window tint. There are some rare cases where window tint causes motors on FXs to be slower and/or eventually wear out faster or just fail. This is not Infiniti's fault because they didn't test out their vehicles with tint. Most people don't encounter issues with this, but I'm just saying. anytime you mod anything, even if it's as stupid small like window tint, and you window motor starts going, you can't just blame infiniti. I'm not saying electrical mods like the HID fogs is your issue and causing the problem, I'm just saying what I hear when you first turn the key does not sound right (it sounded exactly like my FX did when I had played around and not turned the car on for like an hour and then the car wouldn't start because the battery was too low). That's all.

If you really want to know, I would take the car to the dealer and just have them diagnose the issue. Almost always I get them to diagnose these issues completely for free when I do some sort of service like an oil change or some other maintenance. A thorough multi point inspection, for example, costs a lot of money, but my dealer when I mention something here or there will do that free of charge when going in for even an oil change, but I also have a very good relationship with my dealer.
 
Hey jd, don't get me wrong. I am not saying that you don't have a point. If mine was the only '06 FX with this problem, I would think the same way as you do that it may be something "stupid" and "simple" causing the problem. But seeing so many people with different circumstances/ mods having the same problem makes me think that it's something greater than a simple mod error. And I did write that the cold start issue occurred before I put in the HID fogs (and after I got a new battery at the end of last winter) so I highly doubt that it's the fogs. But thanks for your input and trying to help out. I should bring it in and leave it at the stealership for a week or two like you suggested when I get a chance. BTW, nice ride!

Seriously, how do you let Nissan/Infiniti know of this issue? The dealerships are not helping out. Can you directly complain to Infiniti? If so, how? Just for entertainment...I get some bullsxxx comments from the Infiniti service reps when I took my car there. Let me tell you some stupid and idiotic comments I got: (1) "The keyfob to your daughter's daycare is interfering with your Infiniti I-key.", (2) "You must be using poor gas"...BTW, I only use Chevron, Shell, 76, and Mobile (91 octane), (3) "Your I-key malfunctioned.", (4) "Don't know. We are not getting any code.", and (5) "You need to reprogram your I-Key." In short, they have no Fxxxing ideas.

I am really eager to have Nissan address this issue. BTW those comments from the stealership are hilarious! especially the one about the keyfob from your daughter's daycare :tup: That really cracked me up. And yesss "We are not getting any code" is a classic one. Also I hear "we could not duplicate the problem" a lot. But now that my warranty is over I wonder if they'll start to get error codes and duplicate the problem :tonguey:

^^^ I missed reading this. Yeah you are right to exclude the fogs and battery then. :) If so many are having issues with this, I would think a good dealer should have an idea about this already hopefully :)
 
I've been posting this issue for last 2 years at IS and the other Infiniti FX (.org) forums. I heard many advices from many "experts" @ IS and .org. The favorite answer was "throttle body needs to be cleaned", then the next one was "change your battery". After dealing with this for last 2 years, all these "I've done this, and it seems to be working now" appears to be not solving the 2006 issue. I'm saying this because I was there. I thought I did something "right" to solve this ignition issue, but this problem is persisiting. My decision is to get rid of my 2006 as soon as I have the fund to get a new car. Good luck everyone!

I forgot to tell you. I did all my follow-up and mechanical works at the dealers..so called "trusty experts".

06 FX35 Starting Issue

Hi All, been reading this thread and others for a while trying to get a handle on my 06 FX35 AWD starting issues as well. It started in Jan of this year (~35K miles) when my FX left my wife and 2 month old stranded for ~2 hours. I drove to where they were and tried starting the car. After about 15 min we called road side assistance and they sent a tow truck. Between the call to road side and when the tow truck finally was about 2 hours and the car finally turned over. We had it towed to a local Infiniti dealer who kept it overnight and they called me back the next day saying to come get it as they could not duplicate the problem and there were no error codes.

Picked up the car and from Jan to Oct the car ran fine. Beginning Oct ~45K miles the car started the no cranking issue again. I would turn the ignition and the car would try to start but just couldn't. It would take a couple of times before the car started. Now this was intermittent. Some days it started fine while others it would not. When the car started, I could drive all day, off and on without issue. In Nov, the car, when started would idle very odd (almost like it was going to stall). So, made a reservation with the dealer and carried it to them last Monday. After 2 days in the shop, got a call from the dealer saying that they cannot find the root cause to my issue. The car was doing the same thing with them but all the checks they performed come back within spec (they also replaced the oil, air filter, cleaned the TB and replaced the battery without success). Finally they ended up calling some Infiniti Engineers and decided to replace my entire computer system. I am getting my car back today so hopefully this solves my issue. Luckily this is covered under the power train warranty. If this car is still not fixed, she is getting traded!

I'm going out of country on this coming Monday. Do you guys think I should have my uncle drop off the car at Infiniti and have them test with it while I am gone (for a month)? I was thinking I could call in advance and explain the situation to my service advisor so when my uncle drops it off they know what to do. By the way the power train warranty is good til Aug 2012 or 15,000 more miles for me.

Do you guys think this will be covered under the power train warranty? Last time I asked the stealership they said it really depends.
 
Today car sat outside at this temp and -10 windchill all day and started no problem....get a 2009 ;)

Yeah I've been thinking about that for the past week. I was going to do some DIY and what i couldnt do or had trouble with have the dealer do But now it's freezing, things came up, etc and on top of that because things are a bit hectic I'm putting even more miles than usual on. I also have about 900 more miles until I hit 3750 oil change so I figure I'm still ok. Plus now there is lots of snow here and don't want the dealer getting snow in my car cause most likely he would do test drives too because I plan on requesting the trans flash. Ahhhhh don't know what to do now that winter is here.

Hopefully I can get a garage heater, some DIY, and choose on an oil fairly soon eithout going too much over 30k do I can figure out what I will want them to do from the premium list :)

Sweet I got my dash, nav, and IS members reminding me of my maintenance schedule! haha
 
Just a follow up to my post above. The Infiniti dealer here replaced my ECM and for the last couple of days, the car has started without issue. Looks like this solved my problem. Fingers crossed.

Which Infiniti dealer did you go to? I am planning on bringing mine in to the dealer soon and it might help to reference to your dealer/car and say how the ECM replacement seems to fix the problem. They'll want to go through the whole diagnose procedure but at least they'll know what to do at the end if nothing seems to fix the problem.

I took mine to the Infiniti of Roswell (just outside of Atlanta). They kept my car for 8 days. This was something an Infiniti Engineer suggessted as nothing was 'technically' wrong with the car. I saw the work order and they also noted that there were no error codes being sent as well. So, this was a completed shot in the dark. 2 full days of 20deg weather and the car has fired right up on first start and no funky idling either. My fingers are crossed.
 
I've had this issue intermittently for two weeks now. I took it to the dealer on Tuesday morning, and they could not replicate the problem. They also didn't see any codes. I was told that possibly my throttle bodies needed to be cleaned. I was also told that since these cars run rich, driving on short trips prior to parking for an extended period leaves a good amount of unburned fuel in the engine. Therefore, when attempting to start (thus dumping in more fuel), the engine becomes flooded (hence the erratic idle after it starts until the fueling smooths out)... Not sure if I buy this 100%, but that's what I was told.

I asked them to load test my battery, and I was told that it (and my alternator) appeared to be fine.

BTW, I have an '06 AWD with approx. 70K mi.
 
time to add another guy to this growing list.

i have an '06 rwd and it just had trouble starting in the cold. i haven't started it in a few days and it's been very cold here, 20's.

on the first try it started right up, ran very rough for about 10 seconds and then stalled. tried 2 more times to start it and it just turned over. third try it fired right up and ran perfectly. my first instinct is maybe some frozen gas in there since it's been a few days, but i knew i had seen this thread but hadn't read it yet.

i'm hoping to get to the dealer between christmas & new years to get them to address my sticky tach under warranty. i'll try to push on this problem also - hoping to not get stranded between now and then.
