Whining Noise
Experts/Wisemen,
I am having a weird Issue on my SH-RLX 2014 Advanced. I hear a whining noise around 30mph in my sports hybrid when i give a gentle gas pedal to reach to 30-35 mph. I encounter it almost everyday from the past few months. I did not get time to take to the dealership so far. I took it today but as usual the technician could not find the Issue. I also notice that I see the RPM not staying as it should with a steady gas pedal pressure, i see the rpm meter moving 1-2 rpms around 1500 and also feel the car jolting slightly. This is not noticed by the technician. Why I am not surprised right?
Anyone encountered this Issue? I fought with the dealership for not diagnosing properly and finally decided to take to another dealership as I figured they do not have technician who is having expertise for SH-RLX. Before I do that I want to ask the experts here.
Let me know if there is an TSB for this.

First question: Have you tried to see if it does it when in Sport mode? I ask so we can rule out an intermediate switching from electric to the ICE repeatedly.
Second question: Is the noise coming from the front or the rear? I ask because if its coming from the rear, then it is most likely the rear electric motors.
This could also be coming from the dual clutch, especially if its coming from the front and the engine is lugging.
Also do you have the reactive force pedal set to High Force, by any chance?

For Second Question: I believe it is coming from the front. I hear the noise when I bring my windows down and well as windows up.
Lastly : I had it set to High force till morning. I changed that to low force while coming to work.
The other thing I noticed it that the whining is sporadic and significant when i am driving in the local roads and uphill...
After the car came from dealership last night, I drove to work this morning and it was all downhill so did not notice that whining.
I will let you know if I notice it when i drive tonight and over the weekend.

Has your dealership ruled out the timing belt TSB?
The TSB that addressed contact between the timing belt and the pulley causing a whining noise?
You mentioned a particular speed at which the ICE might or might not be running. Is the ICE running when you hear the whine?

Just to clarify.....
I think if it was the timing belt problem, it would happen in "Sport" mode too.....he said it does not....
Also I believe the timing belt noise is described as a "Chirp".....

I am one of those (anal retentive) people who keeps a binder for my car. Everything from window sticker, brochures, mailers, service receipts etc are in that binder. I also keep a TSB section and each time a TSB is posted in the forum that applies to my VIN, I print it out and add it to my binder. I have an excellent dealer, but in the past I have pulled out the binder on a service call to reference a TSB. It just validates you know what you are talking about as we often have communication difficulties describing an issue to the Service Manager.

I must point out that the specific TSB refers to a chirping, and not a whining noise. I think a whining noise would come from an electric motor of some kind (AC compressor, one of the hybrid electric motors, fan, etc). I personally would not let them apply this TSB, unless the Tech was sure that is the problem. I say that only because it is a very involved procedure, and other things might go wrong.
Just throwing this out there: we have a device in the front of the SH that makes a whining noise, only when in pure electric mode. Maybe that device is malfunctioning (whining when the engine is running also) and it needs to be replaced...... I would ask the Tech to unplug (disconnect) that specific device, and then you drive your SH for a couple of weeks and see the whining noise goes away......If not, then they can reconnect it. I have posted specific information on this, in a previous thread.......
