The automatic transmission in the infiniti m37 sport hesitates and struggles to find the appropriate gear. Even upon soft acceleration, the transmission shifts between the first 3 gears before reaching 20mph and all between 1500-2000rpm. This can create a hazardous situation when turning left across a multi-lane, divided road--especially from a stop. The car simply won't accelerate quickly enough. Same is true when entering a highway on-ramp at speeds above 40mph. The car simply does not downshift quickly enough to provide adequate power for acceleration. For a "sport" sedan, this is unacceptable and dangerous.

My infiniti m37x hesitates on take off. When coming to a stop the transmission seem to be down shifting after coming to a stop. It shifts at random times throughout the driving cycle. This has been happening for a long time. I'm taking the car into the dealer this week to get the software updated. This is ridiculous infiniti. I'm hoping there's a permanent fix for this very soon.
I was trying to accelerate from off an on ramp onto a highway and the car completely hesitated. The transmission took a good two seconds to accelerate and get into a safe position to pass, when I was struck from behind by a car in the slow lane. I have made a complaint before about this same issue and something needs to be done. I have already sent my car to the dealership and they reset the TCM, but it did nothing. Please get back to me at [xxx] or [xxx]. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). Thanks
The transmission in the m37's have a major flaw. It is a 7 speed and has a difficult time figuring what gear to go into. When you are accelerating onto an off ramp there is a major delay and the transmission can't figure out what gear to go into. You could be killed trying to get on an interstate because the car won't go. When you slow down the transmission will gear down sporadically. When you are climbing a hill at 30 miles an hour, the transmission will be in 6th or 7th gear. A software update was done to this transmission in september 2012 and helped a little but is still unsafe. By researching online about this transmission issue, there are a lot of complaint from consumers that own a 2011 2012 m37. Thank you.
I leased my infiniti 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. Now it randomly drops RPM's almost down to stalling then kicks it back up (catches it self - large RPM swings) while at a complete stop. I've done the ecu flashes and other tricks that have done absolutely nothing. 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 and there has been a number of times my car almost jumped forward while braking and hit the person in front of me. I am really upset, can someone please look into this, there are a ton of complaints online and no one is being held accountable for a fix. Please see this link to see some of the issues, I thought I was the only one, but that's not the case. Please help!
