Hey guys, just found out there is another TSB for the passenger seat vibration NTB13-063. Here is the link http://x.nissanhelp.com/forums/lates...b13-063-a.html
Anyway, seems like they are replacing the seatback frame this time around. I called the dealer to see how they would go about repairing car thats not under warranty anymore, but has a documented issue. The dealer told me to bring the car in and see if the TSB applies.
Will try to bring the car in the next few days and see what happens.

I never had the seat itself vibrate but they could never fix the rattles the passenger seat headrest made over every bump.

I tired every height setting and even putting some black tape ( had a black interior so it wasn't obvious) below the highest notch to keep the headrest higher. Wrapping the entire post in tape and inserting it wasn't an option as the tape made the polls too large of a diameter to fit in the seat.

I even tried swapping the drivers headrest with the passenger.

I finally just tossed the headrest in the back seat, lol

 

mine is shaking too... where do i get them PDFs for TSBs?

I can confirm that this issue is present in the drivers side seat on the 2014 MY. When braking from highway speeds the drivers seat rocks forward then back upon stop. It feels like the seat isn't bolted on the track appropriately. Apparently, this issue has not been corrected at the manufacturing stage. This could be a potential safety issue in a collision.

 

I have had hundreds of cars and it happens in them all get a wheel balance and alignment and cut all your rotors something is obliviously out of balance it will get a lot better once this is done .

 

I've had all these things done to my car, the seat still shook. Going to have to take it to the dealership for the TSB. The bracket is jacked up and needs replaced.

 

This has been driving me nuts for weeks (partially because of the noise, which seems amplified due to cold weather).
I've been getting a weird rattle/squeak and noticed that if I grab the seat back and apply pressure to it, the vibration and noise goes away.
Thanks for posting a d-load of the TSB. I'll be printing it and bringing it to the dealership for repair.
