Tesla service center tech has said: 1 - "The BMs board did not work, sorry to say. All roads led to a new BMs board being the issue, but at this time the HV battery might need to be replaced." ==> By saying the HV battery might need to be replaced, the tech implies what he calls the "BMs"...

Again, the service centers do not handle the BMS (Battery Management System) boards located inside the battery packs, as they do not open the packs for component replacement. Instead, they recommend replacing the entire pack. However, for the purpose of clarity, it is important to note that you...

Nowadays, it is quite common for individuals to come across claims on the Internet and subsequently share it by stating, "I've been informed that Tesla is no longer producing older model Tesla BMS boards and they are currently scarce within the company".

Which means the "battery management system board" is not available to them to work on. That's true since swapping the BMS boards inside the pack is not something the service centers do. Instead the service centers require you to replace the entire battery pack with a new or a re-manufactured...

The statement made is that your battery pack needs to be replaced, which is a common occurrence. However, that is not what was mentioned in your initial post. You posted, "the battery management system board is no longer being produced and cannot be obtained". It is important to recognize this...

Disseminating inaccurate facts is inappropriate.

This is not just a random post, but rather a deliberate attempt to spread false information. The service centers do not replace the "battery management system board".

How much do you lose per 24 hours due to phantom drain? How old is your 12V battery? Do you have MCU1 or the upgraded infotainment system (MCU2)?

After my MCU2 upgrade, I did a factory reset (after writing down done all my settings) to start fresh with everything and I had none of the issues reported here with the things not working, including the HomeLink. Also, I remember my HomeLink icon was not showing up after the factory rest but...

If those cars were equipped with adaptive cruise control, that would explain their inclusion, as phantom braking can occur even while using adaptive cruise control.

It lines up with my daily loss.

Understood. Appreciate it.

Numerous instances of this occur across various threads, leading to significant confusion and even the spread of inaccurate information.

I know many years ago, there were dedicated tire and wheel shops where you could have your tires shaved to correct any unevenness on their surface.

Any particular ICE or EV SUV?

As you notice, "2023/2024 Tesla road trip / range anxiety tips" is not the topic of this thread ;)

Do you know which month of 2015 your car was built?

If you opt to keep the car and purchase a remanufactured battery, my suggestion would be to invest a couple of thousand dollars extra and aim for a fresh pack from Tesla.

Barry - So nice to see you back (as promised) to provide feedback. How about the SW/UI intuitiveness/ease-of-use?

I would hope so since I've not received the alert to this date. My old pack's build date was January of 2015 and not knowing when in 2015 Tesla switched to the powered fuses, I'm not sure what kind of fuse that particular pack had.

Where did you hear this about the "U" version?

Thanks for the info. And, thanks for mentioning this important exception. My HV battery was replaced with a new 350v/90kWh 1014116-00-C pack about 16 months ago with the build date showing as May of 2022 on its label. I would assume (hope) that it has a new self-powered fuse that doesn't...

What constitutes "Old"? What constitutes "New"?

100% 🤝

That was exactly the case with my old battery in 2019. And then, Tesla "corrected" it for me ;)

Temperature has a lot to do with it. This is my best stat this year:

Hmm, I must admit, I find it difficult to believe that the Google account user ID must match the Tesla account user ID. However, I am certain that you were able to resolve the issue through another means.

The reason I asked was that some owners in the past have tried to share the calculated route with the Tesla app, which is the wrong way. You only need to search for the destination location and share that with your Tesla app. I use Google maps to search the destination location and then share it...

Do you only share the destination with the Tesla app or do you share the calculated route with the Tesla app?

So are the contactors. I forgot, but do you know if the contactors are covered under warranty?

No. I'm just saying this is a better way to triage tickets. That's all.

If this is a new process for all issues, then it's a positive change to triage owners' requests.

There is a different thread on this topic. Look at this estimate which I assume the $1251.70 is for the fuse being on the top of a 2014 Model S60 pack. You may want to contact the owner for more info: https://teslamotorsclub.com/tmc/posts/7746316/

Thanks for the concise explanations 👍

Both fuses listed are "POWERED". My understanding is the new replacement has no batteries.

In this case, “rectification” is definitely better fitting than goodwill.

On the topic of the range: You charge to 90% and won't go below 20% to pamper your battery. That's 30% you should avoid using. Then if you have bad winters you can get hit by up to 30% loss (worst case scenario, rain/slush, below freezing temp, short drives, headwind, heater on, etc.) So...

Sure. I understood that's what the tech is saying and that contradicts what others have posted as to the new fuse not having any battery. Nevertheless, thanks for responding with your info. @brainhouston - Is what this tech is saying?

I thought the replacement Pyro fuse being installed now has a different design with no battery at all.

Of course, I did not want to hear any names! You actually answered my question the way I hoped for. I appreciate it very much.

And that Tesla is in possession of a tremendous amount of data gathered from its fleet over a decade, something no one else in the EV space currently has.

I absolutely agree. I've encountered it first hand multiple times myself in over 8 years of ownership and something others neglect to highlight. Are you interfacing the corporate engineers or with a team overseeing the service centers? What's the makeup of your contacts at Tesla? Many thanks.

I remember you saying that. That's an honest disclosure ;) Also, putting aside all Tesla service center issues, mostly due to the high volume, you take your Tesla to one of them and you know all they do is servicing Tesla EV's. You take your non-Tesla EV to one of those ICE/EV dealerships, what...

Thanks for the feedback. So, more and more it appears the whole thing was a software glitch. I wonder if the alert has been cleared for all impacted cars.

@supratachophobia - My apologies for asking. What's your connection to Tesla? Thanks.

Thanks. There is also one attached to the 12v battery. I saw the mobile tech who was replacing my 12v reaching out to it to disconnect it before the 12v swap. @brainhouston - Do you know if the 12v fuse is also a Pyro type? Does it have battery or is it an entirely different fuse?

I believe the tech writes it but the service advisor can modify it to fit the corporate guideline if necessary. They also use templates since the wordings on different service invoices have the same structures. Either way, this episode seems to be self-induced confusion on their side. I've the...

That might be, but note that he was trying to justify the charges for an updated fuse (the context of the conversation) and saying "The fuse is separate from the HV battery": To me that implies he was trying to say they just changed the "battery" but not his old fuse and that your old fuse...

@teedee - This is amazing! The service advisor, the way I read it, implies (incorrectly IMO) that they used your old fuse off your old battery and installed it on your new pack that you received earlier this year. But then in the invoice provided to you by the same service center (post#161)...

I suppose the new one is on the right of the posted picture?
