Driving my car today a little error popped up and said : “Battery Fuse Needs Replacement - Schedule Service”

Anybody know what that entails / costs?

Ah, you likely have the older version pyro fuse that has a battery built in.
Per this video, it looks fairly easy for service to change.

Weird but today I got the same error in my p90d 2016. Which fuse should I replace? The one on the bottom?

It is likely the bottom High Voltage pack pyro fuse. May need Tesla to do it to reset the alert (especially since it's the main current path).

Damm, only one tesla SC in my country. It's going to be a long wait...
So, changing it by myself will not automatically reset the alert (pics bellow)?

I'm not sure, from what I've gathered, there was a version of the fuse with an internal battery that would only last X years. I think the car just checks the current date/ time to see if it's expired. New versions harvest power from the miniscule voltage drop across the fuse. I expect they change the vehicle config to indicate the new one doesn't have an expiration date (unless it has a network connection?)

Maybe @wk057 will chime in.

Thanks for helping.

Hope that @wk057 finds this thread. Curious about his opinion

Just got the same message this morning on my 2016 Model X 75D and scheduled service. Earliest appt is March 2nd at local service center. On screen message says that is okay to drive. Does anyone know how long it can safely be driven without any issues?

Just a guess, but March 2 should not be any issue.
As to safety, the fuse is only activated in the event of an airbag deployment level crash or if there is an over current fault on the HV bus. That's when it needs to react and activate the small explosive charge.

Please let us know what the SC told You and which part was replaced. Thanks

Odd how we all seem to get the same message with late 2016 Model S or X. Is this something that needs urgent replacement? A ton of guesses here. Does anyone have a strong answer? MUCH appreciated!!

The pyro fuse from that generation is battery powered with a finite life. Tesla replaces it with the new self powered version and updates the car's fuse data to clear the warning.
It is the emergency overcurrent cutoff for the pack and is very important. The only unknown is how long the fuse will continue to work after the warning pops up.

I'm curious if anyone has had Tesla perform this fuse replacement and, if so, could they share how much it cost? I have now received the same error in my 2012 Signature.

UPDATE: Tesla ended up covering it under the battery warranty.

I also had this pop up on my screen. I’ve just talked to Tesla and they are quoting the cost of the fuse replacement on my work estimate as: $11,052.72! Has anyone else had this replaced off warranty?

can't be that high..
but if ur battery is old type, the fuse is on top, so HV pack needs to be removed. in that case def more labor but not 11k range..
whole reman pack is 13k...

Does anyone have a suggestion on where to have the battery fuse replaced outside of Tesla? Or a less expensive option?

I am absolutely gobsmacked at this price! Any suggestions to have this fixed in another way? Does anyone know if someone outside of Tesla will do this or if there’s a way to see what they are charging in other areas? I’m in the sf bay area and I’m feeling very price gouged

Can you post exactly what was quoted?
