I purchased a Nissan 2008 Rogue SL FWD about a month ago. I noticed soon afterwards that when you sustain a cruising speed (really noticeable between 40 - 60 km) and then accelerate slowly to maintain that speed (rpms around 1100) there is a low grumbling noise that comes from the engine and remains there till you stop accelerating. You can get the same noise if you are in a stopped position and press the accelerator a bit. I took it back to the dealer who said they found nothing wrong. After much prodding, the service manager took it for a ride and yes, felt the vibration. They contacted "service central" and was told that this is a CHARACTERISTIC of the vehicle. The dealer says contact Nissan. Contacted Nissan Canada but they will not intervene unless the dealer says that there is a problem.
Oh the service manager where I bought the vehicle, gave me a unique solution - use the shift paddles to shift down a gear and rev up the motor to a higher rpm so you don't hear the engine growl.

Has anyone else experienced this vibration or is it just my vehicle?

I've noticed it too, along with many other Rogue owners. Its been chalked up to the CVT and considered normal. Doesn't bother me though.

I'm with Sputnik on this one....I've noticed it too,
but, its not severe. I also relate this to the CVT
transmission(belts)....it kinda reminds me of when
someone tries to accelerate a car with a manual
transmission while going too slow from too high a
gear....kinda chugs, (in our case it vibrates a
little)?? I'm watching it, but I'm really not too
worried about it.....yet.
(I, also, only have 1300 miles on my car...when I
get to 5k, I will re-assess to verify that it hasn't
gotten any worse...and if it hasn't, that would
indicate that it would be more of a characteristic
of the CVT, and not an actual problem.)

I seem to be the hight mileage guy here so I'll throw in my 2 cents worth. Tomorrow I will surpass the 10,000 mile mark. ( and the poor thing is only 3 months old!!) and I have noticed the slight vibration once in a while. It hasn't gotten any worse since I bought the car so it hasn't bothered me much. I simply accept it as part of the CVT system.
