Whining/Purring Noise From Engine Compartment

[gusbootrogue]

So somebody totaled my pristine 2010 RAV4 and after some power shopping I ended up buying a 2013 Nissan Rogue SV (? the one with all the bells and whistles) with 55,500 miles on it. Seemed like a nice little SUV after test driving it. I've had it about a month. Never owned a Nissan before, but my girlfriend in HS had a Datsun station wagon that we used and abused and could not kill the thing!

A couple weeks ago I notice a whining/purring noise coming from the engine compartment. It happens when the engine is at about 1150 RPM. So I hear it when accelerating or decelerating when the engine passes 1150 RPM, maybe 1200 RPM. It does it when driving or parked or in neutral when the engine hits about 1150 RPM. I've read about the CVT whining noise, but would the CVT noise happen if the car is not in motion (parked or neutral)? My mind tells me "no".

The noise is not so loud it can't be drowned out with the Bose stereo. Is this just normal Nissan engine sounds? Could it just be belt noise? I think this car has a timing chain? Maybe the chain whirs around 1150 RPM? I can't find how to rev the engine in the engine compartment so it's difficult to pin-point the noise when sitting in the car revving the engine.

Anybody else experience this? Any ideas?

Your new-to-you vehicle is equipped with a continuously variable transmission (CVT), also known as a single-speed transmission, stepless transmission, pulley transmission. This noise is common for this type of transmission, and has been discussed ad nauseam in this group.

BTW, the SV is the mid level model, while the SL is top of the line. "All the bells and whistles" would also include leather seats and the around view camera system.

Depends on the noise, I had a odd noise, I called it a vibration, but the nissan guy said I should call it a humming... My one happened more when it was in D with low revs, turned out to be the insulation on the back of the AC/heater matrix and worn down a little and caused the sound (plastic was vibrating on plastic). Maybe worth checking out, as I swore it was a engine noise too, but turned out to be that...
