2007 Infiniti M35/M45



  • Thanks, sfcharlie. It's a Luxury M35, Crimson/Graphite, Journey/Tech (2007 version of each pkg., both of which have fewer bells and whistles than the 2006 versions.) The color combo was impossible to find at a dealership back in March/April, and by the time I was ready to order, they were ordering the '07s.

    I'm very happy that I waited, but I've hardly even driven it much yet - I have an appointment to get some Enkei aftermarket wheels put on it this Friday, and not driving much until then so the stock wheels will be in perfect resale condition.

    In the meantime, I'm reading the forums to figure out the hack to upgrade the Bluetooth drivers on my Treo 650 so it works well in the car!

    picked it up today 22 july. not sure what more to say.. m45, tech package paid 56K ... I really like the 14 speaker sound. I find the voice recognition very good. it can set the tuner to 93.3 whether I say 933 or 933 it had no problems blue toothing to my phone and hasn't gotten a spoken phone number wrong yet. hate the fact I can't watch DVD unless park break is on . trunk is hard to close... any questions? passemger seat is same control features as drive (nice) .

    "trunk is hard to close". Funny, I thought I was the only one with that problem. I find that I can't close the trunk unless, with the trunk open, I hit the open button on the key FOB. I hear a click and that, somehow, resets the latch and it closes. Annoying, but I've learned how to live with it....until my next service.

    My 06 35x's trunk is kind of a pain, but I find that if I actually use the interior handle and give it a good tug, it usually closes on the first try. It is a far cry from the trunk on the Audi I turned in, where you could latch it with one finger after it was closed, and it didn't sound like an economy car's trunk when doing it either. Still, I like the car. We'll see how that works as the time goes on.

    I haven't had any trouble closing the trunk--although trunk does sound "cheap" upon closing, as James mentioned--odd, given solid sound of doors. Are you having the same trunk-closing problem described by "ghstudio" in msg 5866?

    Gas mileage appears to be slowly improving -- measured 18 mpg (using the "old-fashioned" miles/gallons-at-fillup method, not the car's mileage computer, although that was only slightly off, at 17.7) with 89 octane gas.

    Waiting to pick up Treo 700p replacement for current Treo 600 so I can try bluetooth phone. Was it much work to transfer stored numbers?

    Ah, I think it's because the trunk's made of aluminum.
  • james27james27 Posts: 433
    SO are the doors...The Audi's hood was too, and it didn't sound like a flimsy piece, either. You can't blame it on the aluminum, it is a design issue and where they chose to spend the money.

    Could be, but I don't buy a car based on the sound the doors make when they close.
  • sfcharliesfcharlie Posts: 402
    Sometimes people appear (always hard to tell what the feeling is behind the post, so I could be misreading this) to react as if a complaint about an aspect of a car they own and like is akin to a personal attack on a beloved family member.

    Of course, we wouldn't be spending all this time talking to each other about our cars if we felt they were just ordinary objects.

    But, speaking for myself, mentioning that the doors have a solid feel and sound when one closes them is a pretty common and longstanding type sampling of the body-build-quality. While few consumers probably buy (or not) a car through a model-by-model door-closing comparison, it's not a weird thing to notice and on which to comment.

    Also, speaking for myself, my noting that the trunk sounds very different from the doors (something not generally true of cars I've owned) is just a "gee, curious" type of comment and not a "why would anyone buy a car with a trunk that doesn't sound like a bank vault closing?" type of comment, even though I used the word "cheap" to capture my own reaction when I hear it close
  • purplem46purplem46 Posts: 54
    Actually the sound of the aluminum conveys the opposite of cheap. It cost them more to produce the doors, trunk, and hood lids of aluminum and it was done to save weight. The same reason BMW used carbon fiber on the roof of the M6. It saves on gas mileage (I know, but think of the cost if heavier), and improves performance. A fairly brilliant move in this segment, of which I think we will see more of from others in the future.
  • sfcharliesfcharlie Posts: 402
    Thanks, that's a helpful clarification. Once my understanding of something like this changes, my visceral reaction often changes along with the new perspective on what I'm seeing or hearing -- new times and I'll learn to savor the reassuring sound of aluminum :)

    new VQ engine that the G35 sedan is getting (80% new parts, variable cam timing on both intake and exhaust, over 300hp, supposedly more economical too). Unfortunately, not - at least for the immediate future. Maybe on the 08's?
  • I just recently discovered this site and find it a very interesting read. I currently own a '95 Q45a. I love it so its hard for me to justify buying a new car, but I am considering getting an M45 next year.

    One disappointing thing I saw on the Infiniti web site is the engine now has 325 hp versus 335 in the 2006 model. I would have expected a slight hp boost. I would also have liked to see an M45x model (since I live in a snowy climate).
  • ghstudioghstudio Posts: 970
    The 2007 is the exact same engine as the 2006. They changed the way that all cars measure horsepower which is why 335 went to change to the engine.

    for 2008,we are expecting the 3.7 engine or the enhanced 3.5 coming in the 2007 G. Probably we'll also get a CVT transmission which will raise the MPG.

    There may well be a 4.7 to replace the 4.5. Not much talk about that. Also no talk about an M45x.
  • blov8rblov8r Posts: 567
    Not my experience at all. Trunk closes as easily as any car I've ever had ... easier than most. Must be a glitch somewhere in your M. Should readily be fixable. :shades:
  • ghstudioghstudio Posts: 970
    The trunk problem is easily recreatable. If I open it with the button on the trunk or with the button in the car, then I am unable to close the trunk and have it just won't latch.

    If I then press the remote trunk open button with the trunk lid open, I hear a click and then I can just close the trunk easily. This does not happen if I try to push the button on the trunk though...only the button on the remote makes a difference.

    My dealer will get the problem the next time I go in.....
  • pete_l_ppete_l_p Posts: 322
    I have never had the slightest problem closing my trunk, and I typically open it with the button on the trunk rather than the fob. I'm certain that there's a problem with your trunk and that the dealer should fix it. The good news is that it's now easily reproducible. (So much easier to deal with than an intermittent problem.)

    As for the cheap sound people hear when closing the trunk: I have totally handled this by using a chrome plate frame by Jewelry for cars, and by adding weather stripping between the plate and the frame and between the plate and the car. It now has an absolutely solid and high quality sound that anyone would enjoy. Believe me, the aluminum trunk has nothing to do with the the problem. That chrome frame looks just great btw, and I think the M deserves it. :) The noise that people hear (and which I've eliminated) comes from vibration of the plate against the frame and the car, and probably occurs because they use only 2 screws rather than 4.

    BTW my Mercedes CLK has only two screws as well and has the identical vibration and noise when I close the trunk. It's my wife's car and she hasn't complained, so I haven't fixed it.

  • "It's my wife's car and she hasn't complained, so I haven't fixed it."

    'Nuff said! :D

    You realize I HAVE fixed my M45, but NOT her CLK, right?

    But I guess you understand all too well.

  • I was told that this was simply a matter of a processor controlling the injection and that the HP on the 2006 M35x could be raised by swapping out a controller chip. Anybody know anything about that? Sounds too good to be true.

    2006 M35X all black in NYC.
  • pearlpearl Posts: 336
    It is definitely NOT true! Infiniti advertised the new VQ engine in the G as "80% new parts". It has variable valve timing on both intake AND exhaust cams (VQ in the M only has it on the intake side), some changes to the air intake system and some other stuff - so it is not just a change in the chip. The fuel mileage improved slightly (one mgp I believe) for both ciy and highway ratings on the new engine. Not sure why they did not make this engine available in the M - maybe not enough production capacity, OR, maybe the M will get a new 3.7L engine for 08 - supposedly, Infiniti has trademarked the name.
  • rlejr66rlejr66 Posts: 44
    Anyone with the newer models of the M, please chime in. Has Nissan/Infiniti fixed the problem with the radio display for the RDS/Satellite feature? Many of you know what I am talking about. The fact that the entire artist name and/or song title doesn't display if too long. Hard to believe that even US brands have radios that are able to scroll to show the entire artist name or song title and Infiniti doesn't. So much high tech gadgetry on a car and something so simple not addressed.
  • max929max929 Posts: 16
    2007 M35x here with tech/advanced tech. From the 'radio' button display on the main screen, the RDS info does appear for the stations that use it. The full artist/song title will scroll near the upper left part of the viewscreen. In addition, when playing a data disc CD with MP3s, you can see the first so many characters of tag information on the screen for about 15 songs and you can tab over to another screen which will show full tag info for the MP3 that is playing.

    The weather has finally gotten cold here in Ohio with some precipitation. And now it's hit 2006 M doesn't have heated side mirrors like in my old 99 Acura RL. Has this feature been added for 2007?
  • A friend of mine has an M45 and I know it has heated mirrors. I thought it was standard across the series. Thnking back to my days when I had a Maxima, I recall that Nissan put a little switch for the heated mirrors whereas most manufacturers tie it into the rear defroster. Not sure if that has changed.

    I am considering a 2007 M35 with technology package. This is a certified pre-owned offered by a local dealer. Are there any ongoing problems that I should be aware of. I have read about some issues with the navi system and blue tooth. For the most part, have they been solved? I would appreciate any input from 2007 owners. BTW, I loved the first test drive in the car . . handling, power, comfort, etc. I am planning another drive and it would be helpful to know what to look for. Thank you.
  • ghstudioghstudio Posts: 970
    No show stopping problems...just some annoyances.

    The bluetooth system is OK, but you do sometimes get some echos and you do have to speak loudly.

    Some gas pumps still pump fast....which sometimes causes the nozzle to cut off before the car is full. It's an annoyance, but someimes you have to hold the pump nozzle and pump in the gas slowly.

    That's about it....excellent car. Gas mileage is not great, but it really runs just fine on regular gas...a big plus.
  • berkesndberkesnd Posts: 9
    Thanks for the reply,

    Any other thoughts by 2007 owners?
  • laiho51laiho51 Posts: 2
    I have had an M35X since 9/07. I chose it over an MB E350 4matic, BMW 528iX, Lexus GS350 AWD, Acura RL after an extensive comparison. The M35X offered the best combination of features, drivability, price, and reliability. I have not been able to find fault with almost anything with the car.

    The only things I need improvement are: 1) gas milage - I am getting 24 highway and 17 city (I am not an aggressive driver). The car really needs 6 or 7 speed auto matic transmission to get the mileage up. At 55 mph the M35X engine RPM is about the same as my 4 speed auto Subaru Forester and Toyota Corolla LE; 2) engine/exhaust growl (MB, BMW, Lexus do not have this); and 3) the Bose audio system included with the Nav system sounds like a mono system. Infiniti should really look at approaching a high end electronic/speaker manufacturer (like Lexus with ML and Audi with B+O) to get a quality system.

    Any idea on how to replace the In Cabin Filter which is located behind the glove box?
    Thanks for any clues.
