Clicking Sound on Regen Braking

Stranger things have happened. Regenerative braking could very well put different loadings on the axle (etc) than mechanical braking.

 

It's amazing the ongoing development within a model. The replacement axle could well be different from the original due to modifications they've detected would be good to make. Sometimes the modified version will be changed in a RECALL if it affects a significant number of vehicles, but other minor changes just "sneak in".

 

I know they already made some modifications to the headlights due to glare issues, but unfortunately mine was produced in April 16 and they changed the headlights in June 16 I believe.

 

When I bought MAZDA parts in the '90s & later, I had to tell them the Engine Number or VIN, because there were a few versions of parts. And I'd have to tell them that it had the upgraded Brake Master Cylinder. My Nissan gearshift bush replacements were even a different colour from the originals. All genuine parts. On the Nissan, the gearshift was better after I put the new bushes in than it had been when new. We had 2 identical Holdens (GM) at work - one was early in the model, looked identical to the other one which was 18 mths older - but they were dramatically different to drive, the newer one just "felt better". Even the seats seemed slightly different (better). We had no problems with either, though - just lots of minute manufacturing changes.

 

The other thing which happens is that suppliers of parts changes over the course of a model - possibly because of parts prices, availability, even bankruptcy of supplier.

This was a list of suppliers of just one part of the Japanese supply 2016 PRIUS:

[EDIT - I did try to attach it, but PriusChat kept crashing - I'll try later]

 

I'm trying again to see if I can post the list of suppliers of just one part of the car - that was 12 months ago - they could well be different suppliers by now:

 

Hooray!!!! Glad your back on track with the problem fixed. I share your anxiety if this is going to be a prevalent fault for many other Gen 4 Prii.

 

Thanks for sharing the good news. If you got an invoice, TSB or something like that or can snap a pic of the details to share, I know I would appreciate it as it seems mine is probably going to need replaced as well.

 

Just going to put this out in the universe, I seldom come on this forum anymore. I am on Prius #3 dating back to November of 2008. All three of my vehicles have made this noise, almost exclusively while braking and steering to the right. The noise doesn't happen when braking in a straight line. I traded my 2008 in with 146,500 miles. I traded my 2011 in with 101,500 miles. My 2015 is only at 46,000 miles or so, and it started making this noise pretty early on, definitely within the first year of ownership. I always just assumed it was more common to happen on the right side because of all braking scenarios, braking while turning to the right seems to be the most common. When I addressed the issue on my 2008 Prius, they replaced the brake shims and after doing so, the sound seemed a little more muted, but it definitely came back over time, and I just gave up caring about it. With almost 300,000 miles of driving with the issue, I have accepted it to be a nuisance, but not a major cause for concern.

 

I don't believe so, but this was also years ago. I still miss that 2008 Prius, life with kids is just easier in a Sienna..

 

Now that's what a dealership service department is supposed to be!

 

I hope the known good vehicle wasn't in for a different repair!
