"Parking brake functions degraded" - ???

[sduck]

So yesterday morning I was greeted with this mysterious message, pictured below. It went away as soon as I put the car in R to back out of my driveway. Didn't get too concerned, as everything seems to work normally. It came back this morning, and also later in the day after being parked for a while. So I've scheduled a service appointment.

Searching for this on google turned up nothing - has anyone else gotten this one before?

Haven’t seen that one before. Do you use the parking break regularly?

 

[ngogas]

Sounds like it was stuck. But now is good.

No, hardly ever. But I do use it on rare occasions.

There was something from Tesla not all that long ago as I recall about parking brakes not holding or something to that effect. Thought it was under their news and also covered in the Tesla publications. Thinking Maybe it could be related to your message. If I find the link I’ll come back and add it.

You should call Tesla’s support line and let them know you got this message. They should be able to check out the logs remotely and see if there’s anything that is cause for concern.

 

[SMAlset]

Don’t know if this is at all related to your situation OP and the info I found was for MS/X vehicles but here’s what I was thinking about:

Tesla issues safety update on Model S, X electric parking brakes over potential defect

Can’t seem to locate what I was sure I had seen somewhere on Tesla’s site but sure the above was the same issue.

I’d also second calling them and asking about the message.

Doesn’t the car automatically apply the parking brake when you put the car in park? Hence why he was greeted with this message when he got in the car..

Yep, the parking break is the only thing keeping the car from rolling away when in park.

 

[ChrisH]

Hmmm but why is the indicator light on only when you press and hold the button?

Because perhaps you’re manually turning it on so to show you it’s enabled there’s a visual display? Because there’s really no park gear just parking brakes to keep the car from rolling like @Spacela said

Next time you push the selector level in (Park) listen for the sound of the rear disk brake pistons moving (or not if sometime is wrong) - that is 'the parking brake'. As others said, pushing the brake thing doesn't do something different - also, wasn't that removed in a newer update?

Edit: it's the sound of the electric motors moving the pistons in, to be technically correct.

 

[Tripplett]

when you press the button you get one sound and a Park. If you then press and hold the button you get a SECOND sound and a different icon. I've been wondering what the difference is.

 

[Msjulie]

@Triplett I have never seen anything in addition to single motor on calipers for activating brakes; maybe the sound of the motor spinning but disengaged since brake pistons fully retracted already?

Yes, I get the 2 different sounds. And it all still seems to be working. It may just be a sensor problem or something. I have a service appointment set up for it in a few days anyway.

I just got the same warning. Will contact support and see what they say.

 

[sduck]

Ack - last night I started getting the dreaded "12v battery requires service" notice. And this morning, the car is dead in my garage. Will need to be towed, or get visited by a mobile tech. Yuck. Don't know if this is related to my previous issue.

 

[sduck]

Follow up - it was indeed the 12v battery that caused this. Everything's fine after a battery replacement.

 

[David3]

Thanks for sharing. I just got the message again today.. hopefully my car will be ok until my service center appointment..

 

[David3]

I just got my car back from service center. They said it's a hardware issue related to communications but they are still working on a fix. Mine seems to happen only after charging overnight and then I try to summon it out of the garage the next day.
It might be HW3 specific.
