  • Hi guys,

    I was wondering if anyone knows how to operate the Nav system while driving. It's a real pain to have to stop to type in an address especially when there is a passenger who could be entering the info. Anyone knows the solution to this?

    When I purchased the car I noticed that at the dealership and the sales man told me the infiniti mechanics can overwrite that by installing some wire to bypass it. I have not done it myself, but he told me it can be done. If you find out please let me know as well. I know all the navigation system does that and that includes Lexus, Infiniti, Toyota and many others except for Honda and Acura. :surprise:
  • Could use a little help. I bought my black FX35 two weeks ago. It was supposed to come with Roof Rail Crossbars but when delivered, they weren't there. The dealer, Infiniti Tustin, has agreed to add the crossbars, no charge (and with no hassle). However, they also suggested that I might prefer to have my FX "permacoated" instead, that I might find that more valuable to me than crossbars.

    What do you all think I should choose?
  • Choose the crossbars. The silver ones are all aluminum, and the superior construction of it will justify why they cost so much. Warning: The instruction manual states that the crossbars are designed to NOT bear any load. The dealer and Infiniti websites offers several Yakima roof rack items. However, checking with Yakima, they verified that they do not make the crossbar adaptor for any of their applications. Strictly for looks only.
  • Does anyone know if the M45 engine management system can be applied to the FX45 to increase the horsepower to 335HP?
    The engines are identical in the 2004 FX45 and 2005 M45. Are there mechanical differences that will prohibit this, or is this a software update? If available, does the potential cost justify 20 HP (6%) increase in HP? Thank you for any information or experiences.
  • I just bought a 2004 FX35, which is my first-ever SUV and a GREAT vehicle! One weird thing - when I start the car from cold - I get cool air out of the Vent which continues as long as I drive the car (with fresh air In, Temp. set at 60F). However, if I were to stop and park the car, even for only 10 or 15 minutes, and get back in, the Vent air is now hot - even if the outside air temperature is cool. I've brought this to my dealers attention and they are trying to convince me that this is normal - that it will "cool down eventually". I've owned LOTs of cars and I've never had this problem with the Vent air being hot after the vehicle has warmed up. Any clues? Is this normal on the FX Series?
  • This is a well known engineering "goof" in the FX model. The fresh air intake takes in air from the engine compartment. I have an '04 FX with the same problem, and as far as I know it is still present in current models. It will not get better unless the ambient air temp is really cool. Sorry about that.
  • Bummer. My 2004 FX 35 finally has a break down. The passenger side outside rear view mirror died. It won't adjust up or down, only side to side. Something wrong with the motor, most likely. Off to the dealer's. Still disappointing as I have never had a problem with japanese cars before... Jon.
  • I have noticed that when I open the tailgate the door will stay in pretty much any place I put it. I can't remember if it used to rise with just a little push. It seem like it takes a good lift to open it all the way. It seems to do a better job of closing with just a slight push. Is this normal, or does it need new pistons?
  • I'm seriously considering purchasing a FX-35 in the next month or so. It's one of the vehicles on my list to decide between. For the past 15 years I have exclusively owned VW's and my personal experience with them have been wonderful (Corrado, Jetta, Passat). I assumed my next vehicle would be a Toureg but upon reviewing ownership experiences there are too many issues and very, very high cost of maintenance that make for items like brakes, tires, even windshield wipers a bit rediculous. I fear my need for a larger vehicle w/ minimal towing capability (motorcyle rider) and my thus far love afair with VW might be at an end.

    I've done a lot of research finding out about the alternatives and without a doubt the FX is top of the list. It looks to have everything I'm looking for and I simply see no list of outstanding reliability issues that give me pause. If this short list on this forum is any indication of the problems folks are having with their FX'es then sign me up.

    I initially just couldnt get over the materials chosen for the interior on the initial release, but am very happy to see that they are putting in more credible materials on the interiors now. It really has made all the difference in retaining my interest.

    I hope to very soon have a "new fx owner here" message posted.
  • I just purchased a 05 FX35, used, and they are ordering me a owners manual. I can't figure out how to recline the rear seats?? I have looked everywhere for a lever!
  • If the '05 is like the '04, there is a small lever for each seat back low on the seat back (near the seat back/seat bottom crease) and near where the passenger's hip nearest the center of the back seat would be. Look for it near the seat belt buckle. It is recessed a bit so is not readily seen unless you are looking specifically for it.
  • Thank you very much... as of today, I still hadn't found it. One more question... Mine didn't come with an owners manual or a navigaition cd... the dealer said they would order me one, but it has been 3 weeks. how would i locate these items myself?

    I have a 05 FX35 for over a year and it is one of the best cars I've ever owned. That said, I just noticed the compass in the rear view mirror is suddenly displaying the letter "C" only. Does anyone know what this means? Is there a reset button. It worked fine up until a few days ago. I would like to avoid going to the dealer for this so any help is greatly appreciated.
  • The "C" means that the compass needs to be calibrated.. It can go out of cal for a few reasons. To get it back into calibration you need to go to a parking lot and go in a circle a couple times or so (driving at a relatively slow speed) and it should auto calibrate. Normally in driving, it can cal by itself but it needs to have a rotational field at different degrees to calibrate. If this does not bring it to work properly then the mirror compass is defective.
  • For the release levers, just look in the area I described. You will flat, black metal pieces that could look like part of the hinge assembly. Reach under the tab and pull forward. The seat back will release.

    Regarding the owners manual, the dealer is probably the best source. Not sure what you meant about the Nav DVD. The player is under the front passenger seat. It should have the DVD in it. If not, they cost about $200 from Zernin ( If your's does not have one, I think that is a dealer issue.
  • I received a notice from Nissan North America, recalling the headlamp and rear combination lamp. The letter just stated that the old lamp don't comply with the standard, but not sure whether they are too bright or too dim. I am living in a rural area, prefer brighter headlamp. If you guys know anything about this recall, please let me know. Thanks,
  • What year FX do you have?
  • mine is 2005, but many many 2003 to 2006 are in the recall. Check it with your dealer

    Jason...I have owned a 2005 RWD FX 35 for 14 months now...purchased 11 months old off lease for $28, at 45K miles since new and could not be more pleased w the car. I am a gearhead, former racer and have owned a wide range of auto's...My other car is a 2004 BMW 330 Ci and, while the FX isn't as nimble is much more comfortable and ergonometrically friendly. I bought for "usability' (carry my boat stuff)...and performance. Absolutely NO problems of any sort...averaging 19-20 mpg in town...24mpg interstate at 80 mph. Excellent road car. Great seats and amenities...jut replaced other than routine maintenence.
  • I just wanted to let you know if you still haven't received the owners manual it's a lot cheaper to buy one on Ebay then go to the dealer. I got the FX-35 CD with the Shop manual, Owners manual and NAV manual for about $35.00. It's a lot cheaper then the hundreds the dealer wants for the same manuals. If it's not for sale when you look wait a few days and try again it shows up after a while.

    I have had my 2007 FX35 for a little over two weeks. If I come home at night, I noticed that the Homelink light is not illuminated. I have to turn on the interior light in order to ensure that I push the correct button. I will have to double check; but, I am thinking only the front seat window buttons are illuminated at night as well (not the rear seats). This is in direct contrast to the handsfree Bluetooth (which I love). The handsfree will not let me make any major adjustments while driving (which I assume is for safety reasons); yet, I am suppose to fumble around trying to locate the correct Homelink or power window buttons at night?
  • snsnsnsn Posts: 56
    Correction: It's not the power window buttons; but, the door un-lock button that is not illuminated. The door lock button is illuminated.

    We own a 2004 Infiniti FX35 purchased new.

    We found the perfect one (tow hitch, cross bars etc) in Norwood, MA. Tried negotiating a deal but ended up walking away. The salesman was a dolt. The long and short of it -the Norwood dealership ends up shipping the FX we're interested in to New Hampshire. We negotiate the deal there and end up buying the FX in NH, but it wasn't easy. We end up driving all the way to NH only to have the dealership reneg on the deal and after much bickering back and forth end up getting the deal we drove there for.

    Man, the car looks sharp though!!


    A year into owning it I conclude the following:

    1. MISERABLE fuel economy. $58 fill ups on premium -ouch.
    2. Wouldn't be bad if the FX had decent power. No low end grunt, all the power is between 30 -70.
    3. It feels heavy, although well planted.
    4. The throttle is either "sluggish or full on", this is the first automatic I've owned in 8 years; I see slushboxes aren't still that great. (Have DSG in an Audi toy; better but still not perfect...)
    5. Not good in the snow, no better than a front wheel drive sedan. My Audi TT roadster with quattro has much better traction and I prefer to commute in it in snowy conditions.
    6. Harsh ride can rattle interior parts especially in the cold.
    7. The aluminum trim scratches way too easily. Tough with a dog companion. I understand the alum trim is no longer sold..
    8. Geesh this interior is kinda plasticky now that I look around.....
    9. Speaking of plastic, what's up with the plastic rear hatch and fuel cover....did I not purchase a "premium" product?
    10. Strange climate control always blowing cold air. Air conditionong is always on (thus the poor fuel econ??)
    11. I don't have the NAV system so the display screen displays radio and climate. Why are the radio characters displayed so cryptically? Reminds me of a cheap 80s Nissan.
    12. If I get asked one more time how I like my Murano I'm going to scream....

    Man, but that FX still looks sharp!!

    OK so after a year of ownership the battery keeps going dead - numerous times. SECOND time at the dealership and they figure the power is being drained by a faulty seat switch. Geesh - Nissan, maybe the switches aren't placed in the best spot....The FX is returned with a blown radio fuse. By the time this is discovered the dealership has closed for the weekend and now have to set up a THIRD appointment. Living down near the Cape and with the closest Infiniti dealership 35 miles away near Boston, MA this is a MAJOR inconvience.


    ....but that FX still looks sharp....

    Spring of the first year the FX and four people head to North Captiva Island for some fun in the sun. Wonderfully comfortable for 4, quiet, smooth on the smooth Southern highways. However, not enough luggage space in the rear so a smaller suitcase ends up being wedged between the two rear seat occupants. Again, terrible fuel economy averaging 17 MPG or so.

    JUMP AHEAD TO NOW 2/2007), 33,000 miles:

    Yesterday the power steering SH** the bed. Ever try turning 20 inch wheels without it? We've only owned Honda and BMW and never had anything go wrong mechanically....(can't say the same for that Audi, but knew that going into the lease .....)

    Maybe two things going wrong in two years isn't that bad, but I expect more in a premium Japanese brand. This is my first and last Nissan product. I'm not impressed.

    I'd like to point out my Mom just purchased a 2007 Honda Accord SE V6. Fantastic buying experience from Herb Chambers in Seekonk, MA (no dickering whatsoever) and what a fantastic car for 22K...this car feels like it's right from Germany...terrific ride, great seats, sublime engine. Looking at the vehicle content on the window sticker I notice this car has all the same safety/luxury features
    as the FX (for 22K)....what gives??

    I think I've got my eyes set on an Accord V6 with a 6 speed.....anybody wanna buy a previously "enjoyed" FX?

    It sill "looks sharp".....

    (but personally I'd stay clear)...there is better out there.
  • One week thus far holding on...Nice power!!!!!!!!!!!!!!!! I researched used SPORT SUV's for some time, and ended up with a four year old fx-45. After reading about all the issues from all the other "sport" SUV's it was clear I don't want to spend a lot of time going from garage to garage getting things fixed. To further support my conclusion I drove all the different 4 plus year old suvs, and everyone had some problem... From rattles, to inop dash,steering, noises from everything and everywhere.
    I am happy so far... If I could change 1 thing it would be to have one more gear on the transmission so I could milk out a few more MPG.

    Upadate: It appears the dealership I've been going to, Quirk Infiniti in Braintree, is no longer in business. However, Prime Infiniti in Hanover, MA just opened. Found out by going on the Inifiniti web site. Better for me since it's a lot closer. One would think Prime would do a mailing to local Infinti owners giving them a heads-up of their opening.

    Anyway, the FX has been at Prime for over a week now. Sure enough, the power steering pump went. Would you believe there isn't a new power stereing pump to be found anywhere?

    I can't believe even in today's "smaller world" with overnight delivery availbale everywhere a pump can't be obtained. Estimated delivery is March 15.

    In the interim I end up with a 2006 Infiniti G35 AWD sedan. More Nissan junk - would you believe this "premium product" has a prop rod in the engine compartment in lieu of hydraulics? Minimal refinement in this automobile...I can't believe some consider this car the Japanese equivalent of the 3 series....I've owned one and it doesn't come close. How can they sell this car?

    Anyway, the FX goes out of warranty next year. If the power steering went then I would be out a car for 3 weeks and would have to pay for a rental. This simply isn't acceptable and it's bub bye for the FX (and Nissan)......

    My 2003 FX45 is approaching 30K and will need its 30K service. The dealer (Santa Monica) is charging about $670 .. does anyone know another mechanic offering the same quality of service at a lower price. The dealer always marks it up by so much.
  • steverstever Posts: 52,462
    You could compare what the dealer is doing to the factory recommended service as outlined in the Edmunds Maintenance Guide. You may decide to just let the dealer to the required stuff - looks like it should run ~$171 in a 90210 zip code (hey, it's the only SoCal zip code I know off the top of my head :shades:).

    I owned the 2006 3 series. My first and last BMW. It was as you say "junk." Steering column had to be replaced, leather peeled and flaked - BMW would only replace the covering around the AC unit, tires had to be replaced, etc. All this in less then 1 1/2 years of ownership. I traded my 3 series in for the FX35. So far, I am pleased with my decision.

    It's nice to know I'm not alone on this one. My Fx's power stearing pump broke down in Toronto. There is no part available anywhere in Canada. My car too has been in the shop for i week and the part is expected to arrive the week of March 12th. Apart from the pump the truck has been great.
