So posting this here since the Hybrid and non hybrid have the same steering components.
I've been hearing this clicking sound when turning the wheel at lower speeds. It's audible only when the audio is off. I feel I'm hearing this more inside the car than outside and my initial theory was it's the electric power steering motor.
I asked my friend to turn the wheel and I couldn't hear the sound outside. However I don't want a big expense later and my question is if this was a CV joint on its way out, should I be hearing that clicking sound standing outside? And if it is the CV joint then should the clicking sound be louder? Thanks.

 

I have always been able to hear failing CV joints clicking from both inside and outside the vehicle while turning in tight circles. Granted, the last one I had to deal with was at least 20 years ago on a 1989 Acura Legend....

 

It is more likely the infamous steering column noise which is just annoying but harmless. Read the stuff in this link which then leads you to the older threads which contain more information.

Thanks guys. I got it checked out. Nothing wrong with the CV joint. I'm just going to ignore this as my repair shop said nothing to worry about.

 

Before ignoring, I would suggest that examine the boots. If there is a rip, you can address it in time. The awkward part is when you jack up the boot opens up at the top. Just check all around.

Yeah took it to the shop and they checked everywhere. No leaks. Thanks Salim.

 

I saw your post in another thread. For clarification ... the rip in boot if any, impacts two ways .. loss of grease and introduction of moisture & grime. Both of these lead to faster wear of the CV joint. As they wear out, the play increases and you no longer get a smooth power transfer as the two pieces rotate at an angle. This jerky motion, produces the infamous click, click sound and it gets louder as the angle of the rotating shafts increases.
Summary .. the ripped boot leads to worn CV joint.

Incidentally there are other suspension parts which wear out faster than the CV joint in RX [front lower control arm bushings].

Yeah the shop lifted the car up and checked out everything thoroughly. No leaks or tears in the boots. They identified the noise as coming from the steering column. Told me it's not worth repairing it.

 

Sorry, I don't have any info/knowledge/experience on 3rd gen steering column. I have seen some discussion on it in other thread(s).
