Hello everyone. My 2010 HiHy has been clicking when braking and accelerating. It doesn't seem to affect the driving, besides being incredibly annoying and getting slightly worse. I have searched for hours on similar problems but nothing seems to come up to help.

A few things to note:

-The Noise Does NOT happen when I shift to "N" before braking. When I come to a complete stop and shift back to Drive, it does NOT happen either when accelerating. Something happens when braking and happens 'back' when accelerating under normal 'D' driving
-I've visually inspected the CVJs and they appear to be very clean, no tears or leakage
-126,000 Miles on this car
-I recently replaced front brake pads and inspected the areas for damaged parts and everything looked to be in great shape (it was happening before and after the brake pads)

Can anyone help suggest another diagnosis?

Thank you much!

sounds like brake pads moving in the caliper bracket...you just replaced brake pads....I'd say time to take it apart and make sure they are seated correctly.

I absolutely agree that is what I initially thought it sounded like which is why I did the brake pad service in the first place. However as mentioned above I have found out that the noise is not present when shifting the transmission to neutral before I apply the brakes. I think this rules out the brake pads/rotors mechanism. IMO I have been convinced it was also the CVJ because that sound is also familiar and similar--like a needle bearing that is shot, however I am not sure if that can be explained by the Neutral relieving the noise. Unless shifting to neutral disconnects the load on the CVJ from engine braking. That is why I am so puzzled.

It does NOT sound like the Actuator. I am new to the hybrid and regen braking, so I would be a rookie in that department.

oh didn't catch the neutral bit....

Interesting you bring up the needle bearings. I think it was 05Moose at one point said they had been failing on one model and they were used on the output on the transaxles (or something like that, may have been a diff). I'll have to see if that's the case on ours...; I can't remember. But putting it in N would take load off the bearing which would stop the noise stress induced noises...
