That's an interesting video of a Rogue that obviously has serious problems. However, I would say there is no connection to the vibration that most of us are discussing here. The low-speed vibration that most are discussing is subtle, and only occurs within a narrow rpm and speed range, it is similar to driving a manual transmission in a high gear at lower speed (ex. using 5th gear around town). And I believe this specific vibration to be normal and I accept it.funissan wrote:according to Tamoroff Nissan in michigan its the same vibration has every rogue.. according to Suburban NIssan its the same vibration has every rogue... according to the Nisaan Field Engineer that inspected my rogue at Tamaroff NIssan its the same vibration.. accord to Nissan North America sworn testimony my rogue vibrates the same has every rogue. i would suggest to be cautions and be on the safe side and have them to do a hoist inspection while the car is running in drive. i read in a previous post that nissan tells the tech to test drive the suv and if it vibrates no more diagnose is necessary. thats unacceptable..unfortunately the blame will fall to the tech for negligence even thou he did what he was told..nissan has i believe 9 vehicles with cvt transmission and the rogue is the only one that vibrates? common senses should tell everyone something is wrong? the rogue is the only vehicle they what good gas mileage and thats why it vibrates? when Nissan told there dealers not to repair my rogue and falsify the repair orders stating there is nothing wrong was unexcusable. all i can say is i hope everyone that feels the vibration takes it in and have a hoist inspection while the rogue is running in drive.. it only takes 5 minutes to be on the safe side. if they refuse take it to a GM or Ford or any other dealer . i hope no one has my problem

I can only speculate that the Rogue in the video would shake like crazy the faster you were to drive, and at highway speeds the vibrating and shaking would be excessive to the point of not even being able to drive.
The NICOClub forums do not have ability to upload images, etc. You need to host them on places like Flickr, Photobucket, Youtube, etc then link to them.funissan wrote:hi guys, how do i post a copys of repair orders?
I do notice it albeit RPM drops to around 800 RPMS and it happens at around 12~ 18 MPH speed. I also get a popping sound as if something (TC??) is trying to engage hard. I have raised this with Nissan dealership and they, in turn, have raised it with Nissan Tech Line who haven't responded in last two months.TaiLuu wrote:Has anyone noticed when you brake not to hard but a little harder then usual lol that the Idle drops to 500RPM when at a dead stop then bounces back up to normal Idle speed?
I've been experiencing this lately I don't know if its that Electronic assist brake or what but It annoys me when I'm stopping.
I don't think its the Assist brakes cause I've done a really hard braking once when a old lady cut me off and I believe i felt the system kick in.
If you pay careful attention, it's also dependent on how fast you move from the accelerator to the brakes. You can also duplicate it by setting the cruise control, let the vehicle speed settle, then applying the brakes. By quickly dropping engine rpms, you do gain an engine braking effect as well as a boost in engine manifold vacuum which in turn provides more vacuum assist to the brake booster.TaiLuu wrote:Has anyone noticed when you brake not to hard but a little harder then usual lol that the Idle drops to 500RPM when at a dead stop then bounces back up to normal Idle speed?
