    thanks for the update, but I got rid of the M37 because I considered it unsafe to drive due to the transmission problems.
  • engine101engine101 Member Posts: 7
    My 2011 M37 is having the same acceleration problems. It almost stalls when I try to accelerate to pass someone. It also feels like it keeps accelerating when I am on the freeway and hit my breaks slightly. My car is in the shop today and I brought it to their attention so hopefully they can fix it. Anyone else have this problem and get it fixed?

    My transmission does the same thing. I tried to pass someone once and the darn call practically stalled on me. I almost got hit.

    Everyone needs to keep posting about this until it's fix. I have had my car a little over a year and thought this was normal, but I have never driven another car that acts like this.

    Quick thought. Since so many people are posting dire safety concerns with the M either on the highway or just entering traffic and disposing of the car because of their concerns, why not change the name of these postings to; "Last Impressions?"

    Since most members are using this discussion to post anything and everything about the M37, I just took off the "first impressions" in the title - presto!

    That is the fastest "corporate response" I've ever seen! I'm impressed, to say the least. Now, if only Infiniti had addressed their problems with the same timliness maybe they wouldn't be so far up the creek with a paddle.

    Good for you "guy's" you're really at the top of your game.

    DO NOT BUY THIS CAR! I bought the M37 brand new with 28 miles on it. I have owned it for 14 mos and it is back in the shop as we speak! It has been in a total of 9 times, either by tow truck or service guys coming to jump it and drive it in to fix it. I have dealt with both Crest Infiniti of Plano, and the home office of Nissan. Neither are willing to help me with this issue, or get me in another car.
    It has an issue with the battery constantly being drained by one thing or another and they refuse to acknowledge this is a problem that obviously isn't going away. Each time it goes in they assure me the problem has been fixed, and it always breaks down again leaving me stranded. I have owned Mercedes, BMW, etc. and have never been more unhappy with a vehicle, a dealership AND a manufacturer.

    ghstudio: well did you get out of your lease?? for only $1K? I'm still in Hell with my 2010 G37X...
  • almattialmatti Member Posts: 164
    I jsut started to peruse this forum ( I have a 2010 G37X), and in fact have posted here before. After going through this thread which is NOT Headlined correctly, I find there are a multitude of the dreaded Infiniti 7AT problems ....Holy Sh*T...I have posted so many times I've lost count on MyG37.com about this freakin 7 speed AT. I have complained to Infiniti Consumers Affairs dept (ICA) 2 X. District Managers and Factory Techs examined and drove my car : the response is the same: " there is nothing wrong, it is operating as designed"...They won't take my car in return (it's Leased for 39 months until Sept 2013)...I've been pursuing an Early Termination with No further Cost to me..They've offered 2 months off the lease???? Oh Yeah, the first complaint yielded an offer of Elite Maintenance contract for up to 45k miles. The one thing I was able to discern from the Factory Tech who drove with me with a plugged in Laptop to monitor the drive, was that They admit to the Hesitation & Lagging - he saw it on the computer analysis done in "real time"...The Tech volunteered one thing which is discouraging to say the least: The only real fix is to replace the Tranny, all the software and the ECM with "reprogramming" that would help to reduce the Gear Hunting that goes on. He went further to say that to his knowledge, no "fix" was immediately forthcoming from Infiniti Engineers. I beleive this occurred in late November or early December. Sorry for the downer opinion, but it's real from the Horse's mouth.

    What I'm shocked to learn as I now have read through this Thread, is that the M37X is the same as the G37X .....The one thing which I have been pounding with my Dealer was to get me out of the G lease and I would Swap into a new M37X lease. That may NOT be the correct avenue to take.
  • richardnvarichardnva Member Posts: 91
    Just traded my 09 G37x in for a '12 M37x. Haven't had any probs with the M's tranny yet, but I did have probs with my G. After I first got the car I had a lot of problems with gear hunting. When I brought it in for the first scheduled maintenance I mentioned to the service tech and they "flashed" the module which I believe reset it and may have updated the software with a newer version. Regardless, the flash fixed my problems and i never had any more problems. My situation wasn't very severe so I'm not sure if we had the same issue, but thought I'd share my experience.

    I leased my M37 Sport the first month it came out in 2010 (2011 model). The first day I drove the car the issues were apparent. I drove it directly back to the dealership, they said everything was fine..its learning your driving style..(I too have had Mercedes, BMW, Audi etc that learn your driving style) this was NOT the case.

    Well, now I am at 33,000 miles and the issues have only gotten worse. Its been to the dealer a number of times for the JUMPY stops...when breaking (normal non aggressive) the tranny wants to JUMP FORWARD and almost hit the person in front of me. Its extremely scary and Infiniti has nothing to say about this? It not only does that but when breaking it downshifts bad and bumps at times. With the AC on I noticed it does all of this more frequently, although the issues are always there. Ive done the ECU flashes and other tricks that have done absolutely nothing. I will be leaving Infiniti. Sad thing is this car has one of the best designs and most amazing interiors, just one of the WORST engine set ups ever...very dangerous.
  • engine101engine101 Member Posts: 7
    I can't believe you mentioned the JUMPY stops because I have experienced that at least twice and it happens so fast that I thought it was something I was doing! And yes I did almost hit the car in front of me! When I picked my mom up from the airport about a month ago I also noticed when I tried to accelerate on the freeway the engine just revved up and wouldn't budge. I had to take my foot off the gas! At least my mom heard it too. You are right about the car and it's design/interiors. They just need to get the engine down and they will have a TOP seller.

    I have a 2011 M56 and am also frustrated with the quirky engine/transmission anomalies. I am at 40k miles now. Last week I brought my car back to the Infiniti dealer because of a "Chk Engine Soon" light. Dealer said it was due to a problem with the ECM (Elect Control Module) software, which had been updated twice before due to complaints about transmission hesitation. The new s/w seems no better at resolving the hesitation and odd surge problems. And every now and then the car seems to hold 3rd gear till about 4k+ RPM.

    This is by far my biggest complaint about the car. I agree with the above comments that the interior of this car is absolutely beautiful, but Infiniti really needs to fix the tranny s/w! I am still hopeful there will be a fix, but unless that happens soon this will be my last Infiniti too..

    ghstudio, Did you ever figure out the problem with your car, or did you get out of your lease? I am still having problems with mine and do believe it's a safety issue!
  • engine101engine101 Member Posts: 7
    I just found this complaint filed through the NHTSA. Doesn't seem like much will be done about this car unless others report it too! Does it have to be reported through the NHTSA in order for something to be done?

    I HAVE CONCERNING ISSUES WITH THE TRANSMISSION OF THIS VEHICLE SINCE PURCHASE 8/27/2010. THE TRANSMISSION HAS MAJOR HESITATION WHEN ACCELERATING, SLOWING DOWN AND WITH EVERDAY USE(JERKY FEELING IN CITY TRAFFIC) NO MATTER WHAT DRIVE MODE IS USED I.E SPORT, NORMAL, ECO, SNOW MODES. WHETHER YOU PULL OUT TO PASS ON THE FREEWAY OR,PASS BICYCLE ON A NARROW 2 LANE ROAD, AT RESIDENTIAL SPEEDS, THE TRANSMISSION HESITATES DRAMATICALLY(2-5 SECONDS),ACTUALLY TO THE POINT I DON'T FEEL SAFE WITH THIS VEHICLE. I HAVE TAKEN THE VEHICLE BACK TO THE DEALER 4+ TIMES TO ADDRESS THIS ISSUE,CONTACTED INFINITI CONSUMER AFFAIRS, AND WAS TOLD BY ALL, THAT IT WAS "NORMAL" OPERATION.... WHICH IT IS NOT!!! *TT

    Reporting it to the NHTSA may not be the ONLY way to get it done, but it is by far the best.

    Not sure if this helps, but it looks like Infiniti is finally addressing these issues:

    Subject: SB 2011-2012 M37; Shift Responsiveness Issues
    Summary of ITB12021:
    IF YOU CONFIRM One or more of the following conditions: Harsher than expected down shifts when coasting to a stop. Hesitation/lag when accelerating after coasting. Hesitation/lag or harsher than expected down shifts when coming to a stop and accelerating again (rolling stop). Engine rev matching during moderate to heavy braking. ACTION 1. Refer to step 6 in the SERVICE PROCEDURE to confirm this bulletin applies to the vehicle you are working on. 2. If this bulletin applies, reprogram the ECM and TCM. See this bulletin for further detail.

    Only a year late....I bought out my m37 lease....leased a Mercedes e350 for less$'s per month and haven't looked back. I love the Mercedes....hated the m37 transmission which I considered unsafe. Hope this solves the problems for those locked into the m37. I won't buy another infiniti...
  • sgl1sgl1 Member Posts: 34
    Thanks for posting... This TSB must have just come out as I don't even see it listed at Safercar.gov yet. I'm very anxious to see if they finally fixed it. ...It's hard to believe this was missed when cars were initially handed to Infiniti general managers to drive during initial release of this car two years ago. Come on Infiniti, you can do better than that!..

    Anyway, fingers crossed! I'll be back to the dealership very soon and will post results here.
  • cr1t1calm4sscr1t1calm4ss Member Posts: 8
    Had that updated. didnt do anything..... had it flashed? Guess thats not the issue?
  • sgl1sgl1 Member Posts: 34
    I have an '11 M56X. I was excited to hear about the new update to the ECM & TCM. Unfortunately when I brought the car to the dealer they said my car already has the latest updates. Ugh, I thought to myself ...Really hoping they finally fixed these transmission problems!

    When in normal mode, the transimission shifts pretty much as expected, but there's still a delay in response when pressing the accelerator hard btwn 30-60mph.

    However the trouble is much more prominent in Sport mode.. Three issues really:

    1.) Delay in initial response when moving foot from brake pedal to gas quickly.. Seems tranny is not engaged with engine while the car is stopped, ..perhaps to save fuel, but it creates a jolt-effect when wanting to take off quickly.

    2.) Transmission holds 4th gear way too long, to over 4k RPM, during regular driving. Seems this happens if you take off from a start quicker than normal. I understand that Sport mode holds the gears longer, but there's a problem with the software in 4th gear... I typically have to move the shift lever to manual mode, then bump the tranny to 5th gear to compensate for this flaw.

    3.) I'm a conservative driver, but on a few occasions, when driving in more of a sporty fashion... I notice a harsh down shift when letting my foot off the gas when going about 70mph. Feels like a bang in the tranny, as if it shifted to too low of a gear. ...There was definite engine braking as I think it went from 6th gear to maybe 3rd.. Not sure, but that can't be good for the tranny.

    ...Still hoping Infiniti is listening and decides to fix these flaws.

    My 2012 M37, with the upgraded sound system, has a rattle in the doors when songs with relatively heavy bass are played at more than about 60-70% of the maximum volume. The rattle is so significant that it almost sounds like the door speakers are blown. Mechanics at the dealership tested other cars on their lot when they learned of my complaint, and informed me that all the other cars have the same issue.

    If true, this is a design flaw in the new M class Infiniti -- at least I can think of no other answer.

    The dealership was great -- they kept the car over a week, working to fix the problem. They were unable to fix the problem, however. Accordingly, Infiniti sent out a specialist to look into the problem. His report indicated there was no problem, notwithstanding that both I and the dealership techs clearly heard the buzzing. It's unclear to me whether he didn't hear the problem, or if he is saying that this problem is somehow acceptable based on Infiniti design parameters -- he has refused to speak with me, according to the customer service rep at Infiniti with whom I've been speaking.

    This is beyond disappointing. I paid extra for the upgraded sound because sound is important to me. For Infiniti to refuse to address the problem, and even to refuse to do me the courtesy of having the specialist that looked into the issue discuss his findings with me, speaks to a lack of concern for the customer.
  • mdroamermdroamer Member Posts: 1
    I am having similar transmission issues as others have described with my 2011 M37--Transmission is slow to respond when moving from braking to accelerating or even in attempting to pass. I've called the dealership and am taking it in today. I do have to say that other than this issue, I really like this car.

    I will also fill out the vehicle safety complaint.
  • brian7042brian7042 Member Posts: 2
    I have previously posted about my problems with the M37 Transmission. Here is an update

    Several months ago they replaced the torque converter which improved things significantly. The dealer service manager said it was a new model (different, not just a replacement). Still had harsh shifts going into either 3rd or 4th (not sure) but it was obvious.

    Had car serviced yesterday and it appears to have been corrected.

    Stay on the dealer if you have this problem - for me it was the torque converter and software.

    I agree - it is a great car!
  • redbullredbull Member Posts: 26
    Never been here before; I was looking to see if anyone has the transmission lag that I have in my 2011 M37S. Sure looks like it! With 24K miles on the car, this is getting worse all time. For me it's when I take this left turn to go onto a freeway onramp; taking my foot off the throttle a bit after I'm in the turn, and trying to accelerate out I get the dreaded lag - I am just fed up with it!

    While I'm here, things I love about the car: Wonderful interior, excellent engine power and sounds - too bad the transmission you use to control it is so irritating, it spoils the whole experience. I like the looks of the car too - the Platinum paint job with the 20" wheels and spoiler look awesome..

    What I HATE: Really loud tires and harsh suspension. Laughable Studio on Wheels upgraded audio - has tons of speakers but they only work if you have HD DVD media. The sources I listen to, i.e. iPod and CDs, very few of the speakers put out any sound, and the ones that do sound very mediocre. When I first test drove the car, they had a demo disc that blew me away, but you will never hear that stuff in your day to day driving unless you go out and buy expensive media to listen to that will only work in your car. Why can't they keep all the speakers functional for simple stereo sources too?

    What else I hate : Really flaky intermittent electronics issues that never seem to happen when I'm at the service department. And of course if they can't duplicate the problem they won't try to troubleshoot it anyway - typical service [non-permissible content removed]. For example, when you have it set to have the side mirrors point down when in reverse, that works fine, but when you stop and put it in drive they stay pointing down half the time. You have to pull over and stop, and put it in park for them to go back up to normal position. After months of frustration and trips to the dealer, I finally abandoned this "feature" and leave it turned off.

    Also the tilt wheel that never goes back to the position it was in when the car was turned off (except when I have it at the dealer for service, of course).

    My Android phone works fine for bluetooth phone calls, but when I also try to use it to stream audio from the phone it doesn't work well at all unless you like jerky audio with blank spots. When I had an iPhone it worked fine, but I learned to hate the iPhone for reasons not related to the car and got a Galaxy S3. I think car manufacturers think everyone has an Phone so focus on perfecting that.

    When all is said and done, after the 39 month lease is up in Dec. 2013, I'm going for a new BMW 535i or Lexus GS, and NEVER going back to Infiniti....
  • almattialmatti Member Posts: 164
    I'm glad I decided to review the comments here. My 2010 G37X which has 8 months to go on the lease has suffered the "the 7AT" horrors. I had the Reflash applied to the ECU /TCM in June 2012. It's better, but still quirky and produces similar responses at erratic times. It's the SOFTWARE for sure. JATCO makes the tranny. What's so curious is that of all the reviews (Consumers Reports, Edmunds, etc.... only a small article written in one of the Automotive magazines some 6 or 7 months ago, actually brought out the tranny issues. Anyway, Infiniti Dealer just called me to say that Infiniti is now offering an early termination (eat the last 8 months of the lease) provided I take a new Infiniti G or M... After reading this review, I am probably going to pass on the 2013 M37X. I you consult My37.com forum, a thread about the Tranny has thousands of posts. The frustration is mine or yours alone !!! I protested about the performance from day 2 of ownership. Only until this June, after 2 years of driving and complaining, did it become more tolerable. The 7AT ruins the car. All done for the mileage gains it provides. Even the District Manager relayed that to me. Although this offer is tempting and wouls allow me to trade up to an M, i may pass because the posts here are about 2011 or 2012s, but a recent post on My37.com indicated that a member just had a 2013 G37 as a loaner, and sadly reported the same lagging & hesitation. I gues they want you to go to lexus, Audi, or even a Buick (LaCross - that car has caught my eye)...
  • jck4ujck4u Member Posts: 12
    I've had my M37 for two years now with 28,000 miles. Two updates for transmission software have not eliminated the hard shifts, especially when cold. It does seem, though, that the shifts have slowly improved with more mileage but the hesitation when accelerating still present. The only other problem was radio amp which was replaced under warranty. Dealer said that amp, located in the trunk area, was a $2,500 item! I have had 5 Infiniti's and overall I still like the car. However, I would think hard before getting another one.
  • ghstudioghstudio Member Posts: 972
    I would encourage anyone frustrated or feeling unsafe with the infiniti transmission (as I was...I turned in my car 11 months into a 39 month lease), I suggest you check out Mercedes. I went from an M37 39 mo lease to a 24 mo E350 bluetec(diesel) lease and I'm paying less per month than on the M37.

    I will never again buy an infiniti (and I had two M35's prior to the M37).
  • brian207brian207 Member Posts: 2
    My 2012 M37 is my third Infiniti. It is also my last.

    Previous Infiniti cars were well-built, a pleasure to drive. I think they must have decided to forego build quality on the new Ms. These new models are not competitors for other luxury brands.

    Examples of problems. Sound system causes vibrations in the doors so significant that some music is impossible to listen to. The Infiniti engineer acknowledged the problem, but told me my car was within manufacturer specs. He refused my request to be informed of the results of his test. Makes sense, right? Why share data on the car with the owner? Keyless doors work about 80% of the time. Air conditioning turns on and off randomly, particularly on the passenger side. Generally a cheaper feeling than previous Infiniti vehicles.

    Oh, and the lease. Apparently Infiniti is the only luxury brand that doesn't let you out of your lease. Other manufacturers let someone assume your lease. Not Infiniti. Oh, sure, you can get someone to take over the lease, but even after Infiniti approves their credit, you remain as a co-signer. Yes, really.

    Normally I don't do snark, but I think I've earned it, driving this luxury car wannabe.

    Any advertising claims experts out there? Can Infiniti claim a performance level with respect to its sound system if the car itself cannot handle it? What I mean is that the stereo seems to have the output as advertised, but the rattling of the car means the actual performance of the stereo as installed does not perform as per Infiniti claims.

    I came from numerous Acura TLs and got my M37 in June 2010 and it shows where they cut corner, my dealer took 2 days with the regional rep and got the panels quiet. There is supposed to be a TSB to quiet the panels. Hard to believe in the QA proces of designing the car they did not recognize this. Over all I love the styling and the ride, but it took a few dealer visits to get some of the sub-par build issues resolved. What surprised me is that even people that bought cars recently have the panel rattles, seems that Infiniti is not serious about build quality. Also the Bose system just does not compete with Mark Levinson in Lexus or even ELS in Acura, and Acura is offering a Krell sound system in the new RLX.

    The car has been very reliable with 37K miles, but you can feel the build quality issues, doors feel light and don't have that bank vault feel. I may be headed back to Acura. I agre Inifniti leases suck, you can't get out of them and I hear they nit pick you on wear and tear when you turn them in if you are not getting another Infiniti. Also they charge you a turn in fee. Acura is more forgiving on lease turn in and also does not charge you any fees.

    You neglected to mention that the 5 year cost of ownership for the E350 is a whopping $15,000 higher than the Infiniti. The E350 also has transmission issues, and the Command system is a nightmare.
  • skerew1skerew1 Member Posts: 1
    I bought a 2013 model and i have about 1200 miles. just started doing the exact some things posted above. the major problem bein the hesitation at time of needed acceleration. did any of you earlier posters from when this thread ended last spring ever find a solution (besides getting rid of the car)?
  • biensterbienster Member Posts: 23
    I was one of the very early people to experience all the problems the M-37 had. This was because I took delivery of the car in April of 2010 as a 2011 model year vehicle. The problems came fast, furious, and diverse. Clearly, unlike the wine company that advertised that we shall sell no wine before it's time, this car's time still has not come.

    After multiple reprogramming of both the TCM and ECM to no avail and promisses of a new car which never happened, I took the car to CarMax and sold it since the Hyundai dealer did not want the car as a trade. I got myself and my wife each a new Genesis 3.8 sedan. While they do not have the prestige or gadgets of the M, what they do have works. When you want to go it goes without first having a committee meeting to decide if now is the time.

    It appears they are never going to get it right. Like The Leaning
    Tower of Pisa, bad foundation; bad building. Either live with the problems or sell the car. Good luck.
  • sgl1sgl1 Member Posts: 34
    I too have had my ECU TCU reprogrammed several times to no avail. Each time I visit the dealer I ask if there's a new flash for the transmission. Seems they keep making changes but none of them resolve the lag. Very frustrating!

    It's really a shame because I love everything else about the car. Mine is a 2011 M56x. I'm not willing to sell it yet - still have my fingers crossed they'll resolve the software bug before mine is out of warranty.

    ...Unfortunately I'm not sure I can recommend Infiniti to others even though the rest of the car is pretty solid. ...I just don't get it Infiniti.
  • ghstudioghstudio Member Posts: 972
    Hard to believe they still haven't fixed that problem. I'm really glad I turned in my leased m37 when I did....I considered it unsafe.
  • mgoingsoonmgoingsoon Member Posts: 1
    I feel your pain. I've had the transmission flashed twice and still find it frustrating in full automatic mode sometimes. At other times it's just plain dangerous how the transmission behaves. My recommendation is that you do your own shifting. The car has an excellent manumatic mode. You really feel connected to the engine when you slide the shifter to the left. I also like the car better with VDC off. I've found that taking more control over the shifts has made me much happier with my M. The transmission (in full auto mode) has but a single goal: to maximize fuel economy. I recently test drove offerings from Audi and BMW and can report that they too suffer from these issues. This is why my next car will likely have a manual transmission. "If you want something done right, do it yourself."

    I have a new 2013 M37X - Leased on JUne 26, 2013. I grappled for months on the replacemnt of my 2010 G37X. The 7AT was quirky, hesitant, and exhibited poor response. It was improved finally in June 2012 when a new TSB was issued which offered a reflashing of the ECU and TCM (transmission Control Module). The behavior was much better, more responive, and smoother shifting. But after some months, the Adaptive Driver Control feature of the ECU (many cars have this built into the software including Infinitis [check out the Web Site for info], some of the quirkiness would reappear. It was strange in that, the quirkiness would come and go. As mgoingsoon stated, all of this programming is to increase the overall Fleet MPGs at the sacrifice of performance.
    Anyway, I drove a number of vehicles I was considering to replace the G. Audi A-6 3.0T Quattro topped the list; MB E-350 4Matic; BMW 535i xdrive; Lincoln MKZ AWD 3.7L Limited; and the 2013 M37X. I shopped these cars for months. I looked and rove new 2013s, and also considered 2012 or 2011 CPOs. My lease was over in August 2013, but I began looking in February. I was tempted with an "offer" for early termination of the G lease from my Infiniti Dealer (Pepe Infiniti in White Plains, NY - the largest in the world, they say) which supposedly was to waive 6 months of lease payments : 3 From Infiniti and 3 from the Dealer. That did not work out that way and I pulled form the deal: 39 month lease, no $$$$ down, 15K miles per year, $655.00 per month. I'm glad I pulled from the deal. I decided to wait and shop the cars I mentioned above. FYI, my advice is to shop at least 3 dealers for each car considered. I received big variances in pricing from each of them.
    In early June, Infiniti again offered the Pull Ahead program - waiving up to 3 lease payments for a new Infiniti car lease for current leases that mature by Dec 2013. So I test drove the M37X again, shopped 3 dealers, took advantage of the Pull Ahead program (which saved me $425 X 3 = $1,275) which were my remaining lease payments. I had to battle Infiniti USA for the June payment but that's another story. I leased a new 2013 M37X Premium & Deluxe Touring interior (really nice feature !!), $1,500 Down, TTL which came to OTD of $4,500, added Remote Start, and Entire Car Protection package, 16.5 K Miles per year, for $575.00 per month. Without the Entire Car Protection which included a Armour Exterior and Interior protection treatment, guaranties for chips, leather damage, etc., the lease would have been $550.00 - a great deal at Greenwich Infiniti. Other dealers told me that I made a fantastic deal - they couldn't touch that.
    Getting back to the topic, the 7AT drive train, after about 3K miles my Check Engine Light came on. dealer thought initially that it was gas cap issue. It was not. A code P0710 came up which required the application of ITB13-019a - a reprogram of the TCM. At first the M ran beautifully, and then the past few weeks I had noticed some of the G's quirkiness eking into the behavior. After they applied this "fix" (the web says that it is a Transmission Fluid Cooling Sensor failure), Holy Mackerel !! there is much more response, smoother shifts and less gear hunting. A new Pleasure to drive. The dealer didn't actually inform me of any reprogramming but simply had the ITB on the work order to alleviate the CEL. Now, I hope this lasts and doesn't revert back to quirkiness. FYI, I drove mostly in SPORT mode.

    I'm turning in my 2011 M37 in November at lease end, and will not be coming back to Infiniti. There have been pluses and minuses with this car, but too many minuses.

    I have a 2014 BMW 550i on order, and will make the jump. If you want to lease, BMW is the way to go with their high residuals and great terms.

    This is just my experience with the M37. IMO, the transmission lag (or whatever you want to call it) has been greatly overstated in this forum. I purchased a used 2011 M37 w/12K miles. I was very very hesitant after reading the dreaded reviews in this forum and other so called car experts about the transmission lag. However, I am glad that was not the case. I have experience this transmission lag maybe once or twice while driving the M37. IMO, it is not a lag it is just normal driving to me. When it happened in my mind I thought, "Oh, this is the lag people are talking about". It happened on the highway, I never felt like I was going to get ran over or was in any danger. I simply accelerated and the car responded and felt like it shot out of a cannon and accelerated accordingly, similiar but not quite the take-off of a Mercedes S550.

    I will choose to stay with the M b/c I don't like Lexus G, I love the Audi A6, Benz E Class, and BMW 5 series, but I refuse to pay an arm and/or leg for maintenance and repairs and the M is just as nice if not better than those cars, just doesn't have snob appeal of a BMW, Audi, or MB, which I am more than okay with.

    Again this is just my experience with the M, but I felt after reading the posts on this forum that the transmission lag has been greatly overstated.

    My old Infiniti I35 lasted me 200K miles without any major issue, it was recently totaled by a crazy driver on the freeway, it was a hit and run accident, I walked away from the car without a scratch.

    No doubt, I have great confidence in the quality and reliability of the Infiniti brand, that is the precise reason I bought M37, it was a CPO used car from Infiniti dealer, with 27K miles on it.

    I had the car for almost a week now (bought on new years eve, 2013), the engine is very powerful, and the power delivery is very smooth, compare with the other car we owned (Lexus ES300h), this is a much fun car to drive.

    The car is heavy and feel very solid, I have no issue with the 7 speed transmission as mentioned by many here on this board, even when I floor the gas, the car just go, no hesitation, no delay. In my personal opinion, Infiniti is opted for smooth power delivery, and has very short 1st and 2nd gear, the shift is imperceptible to me, and create a luxurious smooth feeling, it also may be misinterpreted as a long gear shift time, but watch the speed build up so quickly, I do not think the car is slow or has problem in power delivery.

    The interior of the car is very classy, you can feel the quality that built into this car, seat is very comfortable, back seats are good from passenger's point of view, as you completely cuddled by the seat and feel really relaxed, something you cannot measure using the common standards.

    Obviously, I like this car, and think very highly of it, if anything from the past can serve as a guide, I think this car will be in my garage for a long time to come.

    Why has Infiniti delayed the introduction of the 2014 model ? Is there a new model in the works?

    I have a 2011 M37S with the same transmission issues listed above (very disappointing car). Had the re-flash etc., but, problems returned.

    Anyone know of recent ECU updates from Infinity?

    Ok, I have a different problem - can anyone shed any light on this ?

    On 2 occasions, I parked the 2011 M37x in the garage and closed the door. Next morning, all 4 windows were down - exactly the same distance. The windows were all fully closed both times when I left the car; especially as it was raining when I drove in this week.

    In both cases there was a thunderstorm with some nearby lightning strikes.

    This is not a significant problem, but its driving me nuts. Any thoughts about an EMP causing the computer to tell the windows to go down?
