Transmission go BOOM! Infiniti says becoming common
Well,
Like it says, I had my tranny go boom and very quietly I was pulled aside and told it is becoming quite common for infiniti to have issues with the 7spd transmissions.
Sad to hear, as it has been a fun car. Saying that, ever since bran new I had issues with it. At first it lagged between 4 to 3 and then eventually slipped in all gears if going more then quarter throttle or above 4k rpms. Now I took it to the dealership and well... They took it for a test drive and blew it apart.
Needless to say, they are replacing it.
Sooo.. If any of you are having problems with your 7spds in any infiniti let them know! I had a new JX in getting a tranny replaced beside my car, and another g37x on its way in to do the same.
It may just be the AWD models too, not sure about the specifics. Just wanted to give everyone the heads up!

Thats insane.
I know many people have reported lagging but that was due to faulty software , sounds like you had an actual bad transmission.
From my understanding the 7Spd auto is used in most of their auto models so if there is an actual a defect in design Infiniti will have a huge problem to deal with.
Glad they are giving you a new transmission.

What were your symptoms? I'm worried about mine. I've had the latest software update but I still notice two major issues. First, the RPMS jump abt 1K on the 3rd to 4th gear change often. Second, it does lug from 5-15 MPG if I make a left/right hand turn onto a new street. It seems like the car is in the wrong gear and doesn't want to downshift.

Please provide more detail. Symptoms and was it one gear that blew in particular? Or was the torque converter?
Mine exhibits odd behavior at low rpms where it bogs in individual gears under throttle.

Well Symptoms were as follows:
When I shift to manual downshifting in sport mode I had a large lag from 4th to 3rd and it also felt hard, not soft while going in to gear. (hard as in sharp quick downshift with clunk noise) That had been happening for at least 30,000km or more, then after being parked over winter I took it out and started to notice slipping under heavy throttle in higher gears (4 or 5th). After that it started to slip in every gear when going over 4500rmps. Then infiniti road tested it to try to get the transmission codes to come up and when they did they blew it apart and stranded it on the side of the hwy...
Being such a large community of Nissan/Infinities in my area, it took about 10 min to get messages coming to me saying we see you broke down on the hwy... then of course I called the dealership and they explained what happened.
Needless to say, kind of scary situation, and the dealership compensated me for my worries.

I had issues with my 6 speed manual tranny...couldn't engage 5th gear w/o massive grinding so I took it to the dealership, mind u I have tons of mods, and they still replaced it under warranty. Fast forward 6 months and now I'm having issues with my 2nd gear...not sure what the deal is with Infiniti transmissions.
