I think lots of people have that little vibration. Mine does it around 62

 

How did you open a ticket and get someone to come and investigate? Through the dealer or did you go straight to Nissan? Thanks!

 

The dealer ran out of ideas and recommended we call the Nissan support line. They were very responsive and we got a case opened. They assigned a representative to the case and the next time he was in our area, we met, he drove the truck for an hour with us in it. Made some diagnosis but needed to check with the factory for more info, then he recommended the tire change. He was very knowledgeable and I was happy with the speed of response. He didn't promise anything but he made a concerted effort to help. My opinion is that the tires are only part of the problem. But at this point the vibration is so minor, they might call it a characteristic of the vehicle. They did make a statement that this is not a safety issue and the truck was ok to drive.

 

I have a 2021 crew cab and I have the slightest vibration around 68 Mph, but this only seemed to start after I had my tires rotated

 

Update, I had the tires replaced and load balanced, but still had the problem, they checked it again and found 1 bad new tire and replaced it again. This helped but the vibration is still there. I'm not sure what their next move will be.

 

Theres so many time consuming items to check that dealers tend to usually blow people off..
Tires, rims, rotors, hubs, differential angle, u joints, drive shaft, half shafts, transmission, flywheel, torque converter, harmonic balancer, fan clutch… I’m sure I missed a few..

Try driving a few other trucks on the lot…

Has anyone had any luck with a diag on the vibration? 2021 titan 4 door

 

I’d also have the driveshaft checked for out of roundness and balance.

 

People have been know to fix the issue by pulling the driveline at the pumpkin and rotation it 180° and bolting it back on.

 

I have a 2005 and the problem exists.
Test drove various years and the problem still exist.
Even posted about it and labeled a "Ttian basher/troll" but numerous other folks confirmed the behavior.
No idea why this issue hasn't never been resolved.
Search the board and you will see there are a few threads about it.
Although an official fix was never release, the rotation of the driveline as posted above seem to have resolved it for some, but not all.

 

Check your steering rack bushings. If they are blown, replace them with beefy aftermarket and rebuild the rack. Worked for me on a different truck with similar symptoms. Took me two years to run down. Your other bushings may also retire early, so get ready. Seriously consider aftermarket rims. Mechs can balance those perfectly.
