Clicking when computer applies brake at low speeds - got an answer from Tesla

[Buckarooo]

For those of us with this issue, Tesla told me that it's a normal sound made by the iBooster that controls the brakes.

FWIW, I find it extremely annoying and not a sound that should be considered "normal" in any new car.

Tesla says it's normal across their whole Model 3 fleet. The fix would probably involve replacing the iBooster with a higher quality part on all cars under warranty. So of course they're going to say it's normal.

If you have the issue and it bothers you as much as it bothers me, perhaps the more we complain the more likely they are to do something about it.

The iBooster on the Model 3 is much quieter than the one used on earlier Model S and X vehicles and is representative of other vehicles using Bosch iBooster electronic braking. Nothing unusual and nothing to worry about.

The iBooster has to generate and apply pressure. Since it's not your foot doing it, but rather mechanical hardware, it makes a noise. The quality of the part isn't the issue. Therefore, Tesla isn't going to do anything about it because it's not a problem.

I never noticed a sound on Model 3 or X.

Does this only happen with TACC in traffic when the car needs to use brakes?

I should probably stop reading posts like this because now I’ll probably hear it.

Yes. It's very noticeable in stop and go traffic.

It's annoying you because you're listening for it every time. A lot of Model 3 owners don't even know it's happening because they've got the radio on or aren't that sensitive to all the little noises going on around them.

We've got quieter cars now there isn't an engine popping away under the hood so other sounds a car makes start to come to the fore. Eliminate the brake booster sounds and no doubt there will be something else happening which will annoy you just as much.

It actually sounds about the same as my Audi A5 when it applies the brakes on cruise control. You may not think it's normal, but all the cars (two) that I have had the apply brakes automatically, make a sound.

Are you using the hold mode?

 

[Buckarooo]

Are you using the hold mode?

Nope, I use creep and standard regen when not in TACC. But the sound doesn't happen when applying the brakes manually.

Interesting.

I don't remember it happening the first few hundred miles I had the car. But it is possible I didn't notice.

In any case, the sound in the vid speaks for itself so if you guys really do think it's normal then I guess it's my problem.

I know that I've had cars make noise during automatic braking, I cannot really say if yours is abnormally loud or obnoxious.

On the quality of the iBooster - it's made by Bosch and is probably the best of it's type available today. Fitted to other high end cars as well as Teslas.

I don't hear that sound on my raven model s.

 

[Msjulie]

Sometimes I hear it but in general, I find the car's sound system easily prevents that and other little niggling sounds from bothering me..

 

[Kevy Baby]

Turn up the sound system
