Brakes screech only when I'm backing up

Brakes screech only when I'm backing up

This weekend, as I was backing out of my garage, every time I touched the brakes they screeched loudly (like metal on metal). As soon as I was going forward, the brakes didn't screech when I applied the pedal, but the next time I was backing up...there it was again. Is the "parking brake" failing to disengage?

You may have a stone trapped.

Or a small twig lodged around the brake pads.

But it only happens when I'm in reverse.

Or a cat you may have run over.

No cat. So, the screech seems to have worked itself out. I got a call from the local Service Center regarding this post and they said that the brake rotors can get crudded up if a car sits for a while or (my case) it was driven in rainy weather the previous day. Essentially, the brakes clean themselves after a while. Still no answer why it screeched only when I was backing up. Perhaps it's able to clear the rust easier when going forward?

A lodged stone can have a directional effect. Oxidized rotors don't sound like metal on metal.

I had the same experience when I first drove my model X. It's the Hill Hold feature. When you are backing out and press the brakes ( and depending upon how heavily you press the brakes ), the car puts itself into the Hill Hold mode. An H appears on the dashboard. If you turn your wheels when the car is still in Hill Hold mode even slightly, you hear the creaking noise. As soon as you press the brake again or start driving, the Hill Hold mode is released and the noise does not come. I was so used to turning my wheel in my old car while my feet were on the brakes, and no noise used to come. However in Tesla, I am learning to change that behavior a bit. Whenever I see the Hill Hold mode self-activated, I don't turn the wheels without first driving the car slightly forward. If you agree with me, let me know as I am also looking for a confirmation that this is happening to most of the users of the model x out there.

I notice when it rains, this problem is worse. No kidding at all but I can wake up the whole freaking community when I back my X out. So embarrassing. Mobile service fixed it once but it came back as soon as the next time humidity is high again.

I have this screeching sound come all the time when I am backing.This always happened in the morning going to work.It seems to me either there is some fault in the design of the brakes in Model X or moisture build up cause it when car is parked for several hours.After driving for a while noise goes away.

simple fix...

Back into driveway wen returning from work (like you probably did @work.
Summon Model X into garage (pretend you are supercharging).
Summon X Forward in morning.

@tipley, it's been over a month... did you find out what it was? just wondering. If not and it only happens going to work, perhaps you better call in sick? : )

@PoloX is correct. I noticed this happening on wet conditions.
Once I parked outside on a cold/rainy night. And I woke up the entire neighborhood.
May be I need to make a service center visit.

poloX | 7 maart 2018

Not even wet, if it rains over night, my car is dry in the garage. That morning, when I back it out, I wake the whole community up.

They are replacing my front rotor now. Said that it should reduce the noise. Picking it up tomorrow.

Has anyone had this issue with a Model 3?
I only have the squeal when backing up to park...but it is very loud and embarrassing in the parking garage. =(
We live in Milwaukee so the closest Tesla service center is in Chicago (hour and 1/2 drive).

Any suggestions appreciated.

Tesla 3 purchased Feb 23; I started having this problem yesterday backing out of my driveway.There was a lot of condensation on the car, otherwise.

Richard | 14 juli 2019

Same problem here had all rotors and brakes replaced. Service center has looked at it 3 times. Any ideas?

Any updates? I have the same bug.
