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.

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

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.
Anyway, fingers crossed! I'll be back to the dealership very soon and will post results here.
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.
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.
I will also fill out the vehicle safety complaint.
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!
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....
I will never again buy an infiniti (and I had two M35's prior to the M37).
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.
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.
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.
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.
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 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.
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?
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?
