2017 brake noise

doesn't sound right. maybe a pebble stuck in there? worth taking a look at the front brakes.

 

Has it been doing the noise pretty much since you got it? Can you localize where the sounds coming from: front, rear, left. right, or maybe right at the pedal or around firewall zone?

I'd agree, not right. Drop by dealership and let them test drive. Unfortunately "not always" will work against you, but hopefully they can determine something.

 

Does the clicking noise vary with speed (very fast and then down to hardly anything at 3 MPH) when slowing down less than 30 MPH coming from the drivers side? I was told its the regen inverter and this noise is normal (two dealerships told me this anyway). If you shift it into Neutral the noise does not happen, at least on mine. Mine started around 6K

 

no, just when coming to a stop. one click.

 

Most of your braking comes from regeneration of electricity and this can cause a sort of noise, but below about 5mph the regeneration switches to hydraulic brakes. This has a different deceleration force and another possible noise from the pads on the rotor disk with a sort of click as they stop rotating.

 

maybe it's just the brake pedal spring, i get that sometimes.

but this last description is greatly different from the o/p's 'super loud click when i stop'.

 

Does it happen every time or just when coming to a stop facing uphill ?
I'm thinking hill start assist coming into operation.

 

Is hill-hold activated just by the car pointing uphill on gen 4?

On 3rd gen it's activated (solely) by extra hard push on brake pedal, on the flat or on a slope is not a factor, and significantly more pedal pressure is required; I can't see it being something you would do inadvertently.

 

agreed, i'm almost to weak to activate mine.

 

Yes on Gen 4 it's automatically engaged, you just let go of the brake, no need to press it down hard like on the gen 3. It still only engages for a couple of seconds, the same as before.

 

You're lucky, mine needs a good firm hoof to activate it. I don't mind really it's just practice for when I need an emergency stop!

 

It shouldn't do, sounds like there could be a problem, brake light switch maybe ?

 

Bottom line is it doesn't bother me. Maybe I just floor it out of habit, I don't know!

 

Try it next time you're out stopped on a hill, just gently let go of the brake instead of pressing it, you'll be pleasantly surprised. It's quite good once you get used to it and it saves you spraining your ankle, it's definitely easier on SWMBO's arthritis.

 

does it beep?

 

That's interesting, that hill hold activates on fourth gen, just from being on an incline. Do you get a light on the dash, some indication that hill hold is activated?

I'm wondering too: what's the threshold, how much incline, or is pretty much always? I'd hate like hell to take foot off the brake and it wasn't holding, lol.

 

it makes a 'super loud click', see the o/p.

 

or, you could go with the sound posted in #6, but that was an older car.
