Email i sent in regards to my transmission that upshifts waaay to early. Let me know what you guys think, if you have experienced and will keep you guys posted. Infiniti forwarded to regional specialist, local dealer has been very accommodating but stumped.

Tsb's were completed already, i asked to have tech drive with me they concur and also will make video for them. Guys i can increase my speed by 5-8 mph hour without my tach moving, when i accelerate at normal speeds the truck slides into 4th and within 1 second it shifts to 5th....anything between 55-70 there is severe lag in accelerator pedal.

" Name deleted, first thank you for the great service you guys provided for me in April when I first used your dealership after moving down to FL from DC.
In the service that was completed on 4/9/14 was the transmission reprogrammed? I do see that it says ECM reprogram so I am assuming yes. unfortunately the same problem exists but it has been difficult to make my way down there. I scheduled a service date on your website and I took the only dates available as I will not be back from travel for work till after the 20th of June. Is there anyway I can drop of my vehicle on the 21st and leave it with you guys? The military has me traveling often. If you could accommodate this please let me know and cancel my appointment for the 4th of July.
Scott, the real reason I am writing though is to make sure I have correspondence with Infiniti on my transmission issue. it has been and recently again is a real safety issue. In my latest travel I went to pass a vehicle at 60 and the accelerator was lagging so I gave it more gas, upon doing so the transmission seemed to kick down and the RPM's jolted to above 4000-5000RPM's accelerating the truck as if I was taking off on a race track. This nearly almost made me lose control of vehicle.
There are several gears above 2nd or 3rd that lag. The best way I can describe it is when you are driving a manual transmission and you up shift too soon and you do not have good throttle response.
there are speeds where I can accelerate for 5-10 MPH and see no movement on the tach. Name deleted, this is not normal at all.
I have a newborn son and another child and now we are forced to use another car as a family vehicle due to these concerns.
All I am looking to do is have infiniti look into this and not assume or tell me it is fixed when it is not. Any tech/mechanic should have been able to drive the truck after ECM reset and know it was not fixed.
Again, love the dealership and thanks for the help.
P.S - I will take video of dashboard so you can see the tach and speedometer on acceleration."
 
I need you help guys

Friends, I need your assitance...

I recently wrote a post about an email I had sent to Infiniti about what I thought was shifting issues. Needless to say the dealership has had my vehicle for 2 weeks and it is finally coming home. Nothing more than TSB's were completed and the Service Manager stated that all the QX's are doing same thing. SOOOO, i finally got out to a couple dealerships today and drove two 2013 QX's and a 2011 QX..to my surprise they did do the same thing. It's hard to detail in a post BUT would love to talk with someone to see if they can notice it too. The only way you can notice it is by looking at the tach while driving becaus ethe QX is so silent. I only started noticing this after I installed the BORLA and could actually hear the engine.

Im looking to see if someone would be willing to give me a call so I can talk through what I am expierieincing. You may be surprised or you may tell me this is normal (Im a very non-mechanical person) PM me and I will give you my cell number..THANKS IN ADVANCE.

Probably will have a borla system for sale too so look for it soon
 
Same Problem

I know exactly what you are talking about. I posted in your last thread. I even got my dealer to change the transmission fluid at my 60k service and it didn't help. I talked to the owner of the dealership who is a good friend on mine and he also told me he has heard from the service manager about the complaints from customers. I also have a 2011 M37 Tech that does not have this issue but i was told by the master tech that some develop this characteristic early and some at higher mileage. He also told me that it covers all vehicles that have the 7 spd transmission (G37, M, FX, Q50, etc). But he said its more pronounced in the QX56/QX80 because of the taller gear ratio. I asked if they have had any transmission failures and he told me no so that has given me a lil piece of mind. I trust the dealer because they will pretty much do whatever I ask them to do. I asked him if he thought it is a ECM/TCM issue he said yes but the tuning is a delicate issue. I have no problem under heavy acceleration very crisp, quick, defined shifts but during the normal driving and low throttle I get the surging.

I'll PM you my contact info.

ive a 2012 AWD. i have a magaflow muff and removed the factory muff and resonator.

i would be willing to test your theory.

currently i dont feel any issues with shifting. i posted an ECM reset procedure that REALLY is felt once its initiated.

i am not sure if the OP has tried this procedure or not, but to others its worth a shot to do if they feel their car is not shifting properly or if its never been done before. its free and takes 5 minutes or less to do.
 
Marc...dealership reset everything! Just drove a 2011 qx and sure thing it did same thing. I never noticed until i really noticed the tach..

If you PM me ur number i will call when you can drive and see.

Thanks

Can I get the link to the ECM reset? Did a search in the forum and nothing came up.
