Did you guys finally figure it out the Quirky transmission problems with Infiniti??
I leased 2011 M37 two weeks ago and realized my transmission has the problem past weekend.
I just stopped by this site to see if there are any case like me, and surprised there are many people have the same problem as me.
I randomly experience hesitation 2-3 sec when I press gas pedal from the slow driving or stop position and upshift aggressively, not proportionally.
It smooth and consistant mostly and I expect this mode should be all the time, but it is not.
It over accelerated and not consistant very randomly.
I will call and talk to my Infiniti service center in Chicago where I used to go, and see what they say.
I just worry what if they say this is the normal operation.

I had experienced this problem for the better(actually worst) part of a year with my early (April 2010) model M-37. The dealer insisted I was the only one complaining. That lasted for months on end only to be replaced with "a fix is in the works." When I started reading about the fix at this wonderful sight my dealer claimed to know nothing about it. I contacted Infiniti customer service who in turn contacted the dealer while I was on the phone.
 
There is a re-mapping of the computer available which was done to my car. This resulted in about a 97% fix. While I can live with this until the end of my lease, after five various Infiniti's I doubt I will stay with the brand. This is just no way to treat the (repeated) purchaser of a $50,000 vehicle. They should be ashamed of themselves releasing a car like this and the subsequent treatment of an obviously loyal customer. By the way, the Navigation system is years out of date. There is a road I drive on twice a week that shows on a 2003 edition AAA map that still shows me driving through an open field. Entrances and exits on Florida's Turnpike as well as speed limits are also years out of date and so far there is no fix for this.

The new mapping of my transmission improved the operation but issues remain and I am not satisfied. Inconsistent operation, harsh up and down shifting, and that damn hesitation when accelerating from slow speed. My dealer initially tried to tell me the operation was normal but finally admitted that the sales manager noted the same issues with his new M37 company car. I have the latest update per the new technical bulletin but conclude it is only an improvement not an actual fix. After four Infiniti cars this may be my last one. How can Infiniti produce an auto with so many great qualities and then screw it up with a poor transmission that they can't seem to fix. And what were they thinking before the first one was sold? They had to realize the problem but went ahead anyway. Unforgivable.

After I dropped off my M37 and I recevied a call from service center that they couldn't duplicate the problem for the transmission. And said this is the common complaint from new buyer of car. He said I will be used to it.
They scanned and couldn't find out any mal functions on transmission.
I will take back my car tomorrow but still worry what if the same problem occurs in the future.
Service guy said they never have heard about new software update for the transmission.

I am not sure I agreed with you sentiment. It is a shame that Infiniti release a car with the transmission program not completely work out and they suffered by having slow sales and has to put up with subsidised lease program to move the cars. But the purchase decision is yours.. Don't you do any research before you buy the M? The transmission problem was discussed on every car mag reviews that I saw and in every single M forum that I visited.. You have ample opportunity to weight the + and - of the car before making the purchase. Don't blame Infiniti for your buyer remorse... Blame yourselves for making the wrong purhcase decision.

My car was leased in the second week of April, 2010. At that time zip, zero, nada, gar nichts, etc was written about the transmission issues. I'm going to go one further; I don't need a lecture from someone who neither knows nor was there! The test drive available, around the block, was not time to reveal the defect! Being our fifth Infiniti in 7 years I had a lot of faith in the dealer, the brand, and our 2006 M-35 which we still have. I was currently driving a 2007 G-35s with a six speed manual and had little experience with automatic transmissions, but was forced out of my G due to knee surgery and the pain associated with a difficult and slow recovery. After 3.8 million miles over 39 years in 20+ manual shift cars anything that eased my pain was a welcome relief. If you haven't walked in my shoes don't be so fast with flippant, ignorant judgements!

I think you were a little hard on bienster. During my test drives last year, before purchasing the M37, I did notice harsh shifting immediately after start off which I finally determined was the first shift into second gear which happened almost immediately. Did not notice the harshness in the other gear changes. The dealer told me the transmission would smooth out after it "learned" my driving habits. Wrong!
 
I read every article I could find on the car in many car mags , including Car and Driver, Motor Trend, etc. and remember only one writeup mentioned that the tranny sometimes seemed "confused". What an understatement. Even the article from Consumer Reports did not mention any issue with the transmission performance and they are not bashful about presenting a problem. I read a few forums but did not get the sense that this was a major issue
 
In the end, I say, yep, it is my fault that I decided to purchase this car. But I did not know or expect that the transmission would be as eratic and aggravating as it has proven to be. Maybe I just got one of the bad ones. My other Infiniti autos were great cars and I fully expected if there was some kind of issue that Infiniti would promptly correct the problem. Apparently, a bad assumption.

There are actually updates for both the ECM (ITB11004 engine)
and the TCM (ITB11008 transmission). So make sure you mention both when you bring your car to the dealer. The more I drive the M after the software flash, the happier I am. It has made a REALLY big difference by eliminating the "hiccup' when you start up from a stop, and it has even smoothed out low-speed downshifts. It's probably the best thing to happen to my M since I got it.

#111 of 187 Navigation, iPod and Bluetooth Updates by m4m

one more update was also applied: ITB10066 which "adds Call Waiting, gives you the ability to call contacts in your address book by name, fixes some iPod and Bluetooth issues and enhance Navigation performance."
That upgrade definitely made things better and increased functionality.
