I have a 2011 g37x sedan with 9500 miles and I don't know if it's just me but my car feels like it jerks a little when I'm slowing down and I also feel that there's a lag from when hit the gas pedal to the actual movement. Does anyone have this kind of problem or is it just me

 

Th eres two updates that need to be done to the transmission for 2011, you can ask the dealer if it's up to date for the lag it should help a bit and for the jerk I have no idea doesn't seem normal

 

simple thing to that sometimes is a easy fix.

do the ecu pedal rest procedure

 

I have a similar problem. If I do the update would that mess with uprev tune? Excuse my lack of knowledge but I have looked for this answer and got nothing

 

I heard you don't need the update if you have uprev but not 100 percent sure

 

Ya I'm not sure, trans has harsh down shifting and somethings got to happen but I don't want to loose my uprev if I do the update
