My Model 3 broke down on Thursday evening. The dreaded 12v failure.
Indications were messages like "Vehicle may not restart","Electrical system is unable to support all features" followed shortly afterwards by red warnings to pull over as the vehicle was about to shut down, which it did.
The good news was that this all happened whilst the vehicle was safely stopped at Amesbury superchargers. I had plugged the car in and after 3 minutes or so the charging stopped. I thought it was a faulty charging stall and so I unplugged and only noticed the real problem when the car wouldn't engage drive.
Bizarrely, just before the car went to sleep the windows started to open. I managed to close all bar one before power died completely. The window that remained open was fortunately on the lee side of the weather.

I phoned Tesla.
The call centre is in the Netherlands but they quickly saw from the telemetry data they had received before the car went to sleep that it was a recovery situation. They arranged for a hire car to be sent to me and arranged for the car to be recovered. Brilliant. OK so I had to hold for about 10 minutes initially to get through but that was it.
Since lockdown I have a routine of reading a bedtime story to the grandchildren via FaceTime and so I cancel that. I'm sure I missed it more than they did.
The hire car from Enterprise was with me within 90 minutes. I needed my driving licence and a credit card (£1 refunded charge) to get the hire car. I pondered all the occasions that I had previously left the house with neither in my possesion especially since I could pay for anything with Apple Pay on my Apple watch. Luckily I had my wallet which I seldom need to use nowadays with me. Although I was suitably dressed for the conditions the hire car meant I could now sit and wait for the recovery in the warm. A Vauxhall Corsa is not particularly comfortable but it has a good heater and Apple Car Play is a great feature.

Having read about this type of breakdown on this forum a couple of years ago I had bought a battery booster power bank (which includes a torch) and carried it in the car (although I hadn't checked its state of charge since last summer, it was thankfully indicating that it was still fully charged) I opened the round port on the front bumper and connected the booster which successfully popped the frunk. I then connected the booster to the 12v battery and, nothing happened. I must have repeated the connection about 10 times but still nothing. I'm not an electrical guru but clearly there will be wiggly amp explanation for this. @arg ??. I was hoping I could at least close the damned window and secure the car, but I couldn't.
An hour or so later the first truck arrives on the scene, lots of flashing lights and grubby DayGlo clothing, and it was a welcome sight but it soon became apparent that 'these new fangled electric cars' were not something the driver had any knowledge of and so we would wait for his buddy to turn up. The second wagon arrived, more flashing yellow lights and loads more DayGlo clothing and head torches. The driver of this wagon had 'done hundreds of these' and had brought an entourage to pass on his knowledge and wisdom. He explained to his audience how to pop the bonnet using a 12v booster and where to find the 12v battery. 'Is that the battery?' one of his apprentices asked pointing to the 12v battery, imagining that it was the sole power source for the entire car. His battery booster did however produce a satisfying clunk as the car seemed to re-energise and come back to life. The screen came on and I was also able to close the offending window. He proudly demonstrated how to get it in to TOW Mode once he had got round to finding the option on the new V11 menus, except that it wouldn't work. The selection was greyed out. No matter how hard he stood on the brake it wouldn't engage.
Despite two recovery vehicles being on scene they could only muster 2 skates to winch the car on to the low loader.
"We'll give it a go" was not a solution as far as I was concerned.
"I'll jack up the front to check if the front wheels are locked." I understood the logic but I pointed out to his audience the risk of damage to the main battery through careless jacking and produced a puck to show what was required to guarantee a safe lift. I showed the jacking instructions in the breakdown booklet and the expanse of red areas. The booklet was in the glovebox and I had managed to find out how to open the glovebox on the new screen menus before the car shutdown to get the Tesla breakdown phone number. Damn those software updates.
I had assumed they carried self-jacking skates but I suspect they actually only had the cheap ones that required the car to be jacked because recovery man no 1 expressed his concern about not having the correct kit and how it might be better to come back in the morning with all the required kit. If there is any doubt there is no doubt to my mind and I agreed and encouraged this plan of action. I would go home and they could return in the morning and finish the job.
I was a little uneasy that recovery man no 2 had not completely bought in to that option and I suspected that as soon as I was out of sight they would return and jack and winch and drag to their hearts content. I had to wait until they departed in any case as they had blocked the Corsa in. As I drove off I saw them watch me depart from the nearby garage forecourt. I went round the block and returned to the Tesla. The windows were down again! Once again I managed to get all bar one back up. The drivers door would not shut properly either. I decided to sit and wait in the warm Corsa for their return in the morning. I let Tesla know the plan (or more truthfully how unimpressed I was that they had sent such a poorly equipped and dodgy recovery company out to me and that I was now sitting guarding the insecure vehicle overnight).

I sat in the warm listening to an audio book that had remained unfinished for months as the Tesla iced up overnight.
Next morning dawned slowly. I can't remember the last time I had a breakfast at McDonalds but apparently they don't do a 'big breakfast' anymore, who knew? The coffee was OK though. The Apple watch battery had gone flat during the night and I don't carry a charger for it. I pay using my phone.
At 8am I called Tesla for an ETA. They rang me back at 9 to say the recovery company will contact me.
No they didn't.
I ring around cancelling this morning's engagements. A 2 minute job if I'm honest.
At 12:30 that audio book finally finished. Time to call Tesla again. This time I insisted that a new recovery contractor be appointed. Tesla fully understand and agree to set about finding an alternative.
I ring and cancel the dental appointment set for this afternoon. They aren't very happy and talk about charging me for the late cancellation. I explain I have broken down and I just know they don't believe me. New appointment made in April. April!
I start ringing around local recovery firms. It quickly became apparent that as soon as you mention Tesla they suddenly become unavailable. A chat with one chap revealed that he didn't have the special gloves and boots required for electric car recoveries. (!) One quoted £750 but it would be tomorrow.
Meanwhile Tesla had appointed a new firm to manage the recovery. This firm promptly called me and it soon became apparent that all they did was look at a map and appoint a local contractor who was ...... yup, none other than, the original outfit, Firm X. I declined that option.
I realised my travel insurance included RAC vehicle recovery and so I called them.
Not so fast grasshopper. This is 2022 and so you don't call them but log your breakdown online. Who knew? They SMS you the link after pressing option 1.
Filling in the form takes about 3 minutes and then you press send and then, ... well, nothing happened... They say you should receive a text and so, since I didn't get one, I go through the process again, and again and once more for luck. I download the app. It has the same form and the same result. I ring my wife to log the breakdown from the home computer and once again nothing happens. I ring the RAC. Eventually I am asked by the system whether this is about a previously reported breakdown, and I foolishly decide it is. And now comes the entertaining part because it asks you to say the registration of the vehicle.
The voice recognition results are so bad, so appallingly bad, it is frankly hilarious. I tried BBC english, NATO phonetics, a Scottish accent, and other accents that are not particularly PC. It eventually kicks you off the system and you have to start all over again. So unless you are Jeremy Clarkson and want to make a hilarious 30 minute TV programme about it, I recommend never to try this option. I later discover that if your breakdown has been properly logged it will recognise your phone number and so you don't actually have to endure this comic procedure. Anyway, I also eventually discover that if you hang on and on (and on) and select the vulnerable person option eventually you will speak to a helpful and charming human who will log all your details in the good old traditional manner. The phone is meanwhile pleasantly pinging away in the background with reassuring SMS confirmations. I take the opportunity to specifically mention to them that I would prefer an RAC badged recovery rather than a contractor but if a contractor is appointed it must not be Firm X. No problem, 'we shall keep you updated'. That wasn't quite true....
I call the local Tesla Service centre where the car will be recovered to. They are expecting me and have a Tesla loaner already allocated. They apparently close at 6 for the weekend but I would need to be there by 4:30 to get the loaner.
The hope of the car arriving there today slowly, but surely, fades as it grows dark again.
Around 5pm I get a phone call from Firm X who have now been told by Tesla that they are no longer required. That's 5pm the next day. I reminded them that they promised to be here first thing this morning. I had given my Tesla keycard to them the previous night when the plan was they would recover the car without me being there and they now to wanted to return the keycard. I said put it in the post but they wanted to hand it over personally. I told them I was in exactly the same place where they had effectively abandoned the car last night and that I had asked Tesla to cancel their participation because of their sub-optimal performance. I then discover they had now been appointed by the RAC to do the job! We mutually agree to cancel that.
Storytime for tonight is cancelled. 2 nights in a row missed. That hasn't happened before.
Back on to the RAC again thankfully without voice recognition being required and eventually speak to a human who apologises and promises to appoint someone else.
I get called by a Bournemouth based contractor who wasn't told it would be a 4 skate job and so can't do it.
Back to the RAC again.
I then get called by a contractor in Durham who says they will do the job on Monday. Durham. I'm in Hampshire. Monday? No thanks.
Back to the RAC again.
I'm giving up hope here. It's dark again and I'm not sure I can face another audio book, or a McDonalds. I keep Tesla in the loop and they say if I'm unsuccessful they will try again to resolve the situation, somehow.
At about 11pm I'm called by the RAC Specialist Intervention Team. These folk are the A team. They text you a direct dial phone number and are on your case.
Within 10 minutes I'm called by a contractor who knows who I am, where I am, what the car is and what needs to be done and will be with me within an hour.
About 10 minutes after that the Specialist Intervention Team call me to ask if I have heard from their contractor - genuine concern and a follow-up, I'm impressed.
This is what the RAC service should have been like 7 hours earlier!
The recovery wagon arrives. Yellow fashing lights and clean DayGlo clothing. This guy knows what he is doing and explains that he will wait for a colleague to turn up and they will do a 4 skate recovery. He also says that he will make sure the car is left inside the workshop at their yard until Monday when it will be moved to the Tesla Service centre. I'm quite happy to leave this guy to get on with the job. He turns out to be ex-Army and it shows.
Home 30 hours later. On the way I update Tesla.
To bed, to sleep, per chance to dream....

During my stay at Amesbury, quite a few people noticed the open window but only two of them actually bothered to investigate further. Thank you ladies.
I chatted with several people who were charging there that had tracked their car's journey from Fremont and China on this forum! Mr Miserable was not how they imagined! I take this as a compliment to my youthful dashing appearance rather than any alternative.
Only one young chap knew about the 12v failure and knew how to then pop the frunk.
During the 30 hours I estimate only about 80 cars visited the chargers and the busiest time was between 3 and 7pm. I would say about 50%- 60% were splash and dash and 15-20% were charge to 100%. Model S/X seemed to take forever.
I'm astonished at the speed some folk think is acceptable to drive at in a car park.
The chargers were also visited unsuccessfully by a brand new Hyundai Ioniq and a Model S without a V3 adaptor. A Polestar had a quick look as did an old Renault Zoe.
Litter at the site is a problem.
I saw that MIC Model 3's often produce steam from the front offside wheel arch when charging. I've not noticed this behaviour before but saw several new cars do it.

Lesson 1: Keep your phone charged or better still keep a charged USB power bank in your car incuding a charging cable (the hire car will probably not have wireless charging). Calling Tesla or the RAC requires long phone calls, most of it waiting on hold
Lesson 2: Keep warm clothing including a hat, in the car (or in the frunk). A headtorch I kept in the frunk was very useful despite the area being reasonably well lit.
Lesson 3: Keep a 12v booster battery in the car so you can access the frunk. Most can also be used as a USB powerbank for your phone. I thought it would provide 12v power to the car as well but I was disappointed to find it didn't.
Lesson 4: Don't totally rely on Tesla to recover you - they just use local contractors who may or may not be any good or able to arrive promptly. Membership of AA/RAC gives you options. You may already have such a membership as part of an annual travel insurance package.
Lesson 5: It's not such a burden to carry a slim wallet containing a credit card, driving licence and Tesla keycard, at the very least, with you always. Put your phone number in your wallet (lesson learnt from a previous experience).
Lesson 6: Don't expect a quick response. I was in not in a remote area. I had good 4G mobile coverage. It wasn't a weekend or Bank holiday. I was parked in a safe place with excellent facilities nearby. The Holiday Inn was great with decent coffee and food, albeit a little pricey but with a 10% discount for Tesla owners. The weather was OK, cold and wet and then icy, but it wasn't snowing or anything severe.
Lesson 7: Carry jacking pucks. Prevention is better than cure.
Lesson 8: Try and keep dental appointments if at all possible. There is a large backlog at the moment.
Lesson 9: If you've not had a McDonalds recently you are not missing anything.
Lesson 10: I'm not sold on audio books but they did help pass the time.

Today is Saturday, the car is still not at the service centre and won't arrive there until Monday. The story is not yet over but fingers crossed ....

Is there a way of checking or monitoring the health of the 12v battery to avoid this?
This isn't a case of a replacement 12v battery solving the issue as I understand it (which I don't, yet).
What I want to determine is what clues to impending failure are sent by the car's telemetry.
If those can be identified then Teslafi or Teslamate (or even Tesla itself) could warn you to get to a Service Centre before the inevitable occurs.
 
Given the excessive wait, was a Tesla mobile ranger an option or is that not a thing in the UK?

I’ve known them to come to people’s home and swap out 12v batteries. They would know the right processes and no towing required.

Thanks for the write up and sharing the story. It does make me think about planning and preparing for the scenario as a I have an aging 12v.
Interested to know if local SC offered this. Could have been a potential quick win. Many SC now operate on Saturday in UK too so feasible tech could have came out to assist
 
As someone else asked, how old was the car, and how many miles?

This is the first time I’d read of a 12v failure while the car was awake, all the other occurrences I’d seen were that the 12v battery was no longer strong enough to boot the computers or close the main battery contact.

I’ve mentally factored in changing mine at 2 years old, so far it’s just passed 1. Also hoping Tesla will be retrofitting the new lithium-ion batteries by then.
 
Oh my what a palava.

I wonder if it's possible to disconnect the 12v battery (to isolate the fault), wire on another 12v source from the frunk. Then drive the car again.

Or is it just simpler for the breakdown services to fetch a spare battery and fit it.

There have been previous discussions that a
9v battery doesn't always work to release the frunk, whereas those small 12v batteries always do work.

It will be interesting to know if there are early signs of failure via the API, how often the car needs to keep topping up the 12v might give a clue, or patterns in the 12v battery voltage readings - so long as other things are not constantly waking the car.

I imagine Tesla have struggled themselves to find a way, otherwise they'd have done it for all situations already.

When the main battery is alive and the DC-DC circuits alive, why does the car even need the 12v battery.
 
Please excuse my ignorance - but if the 12 Volt battery is flat isn't there some way of replacing it? I know the Tesla batteries are different but is there no neat solution for attaching a temporary battery to the battery terminals (with the dead battery disconnected - as it may have shorted cells) - after all the Frunk is large enough and safe enough to fit a large temporary solution.
Even if the dc-to-dc charger is the cause of the fault wouldn't this be enough to get you home safely?
Or am I totally missing something here?
Oops, looks like I'm not the only one to mention this in the last 4 minutes :)

Aug 19, 20K miles, one careful owner, never raced (except at traffic lights when BMW in next lane)

I love that A23 battery solution.

@Mr Miserable , although its been somewhat of a nightmare - and by the way I would never abandon my car either, Your post was so informative, well written and useful, an interesting read and amounts to a true appraisal of Tesla service in a worst case scenario but clearly you never gave up - and you certainly don't sound too miserable either.
I really hope you discover and share the warning signs of the 12v failure as as sure as eggs many of us will have this to come in the future. I too would rather replace my 12v battery now than wait for an issue to develop and I hope there will be a lithium option due to longevity of this type of battery. My car is not yet 2 years old and only covered 6300 miles, I'm retired and drive when i either want to or need to, truth be told i don't actually need a car but a car to me is as important as having a leg - loved cars all my life. Fingers crossed Tesla update you with their analysis of how and why your battery failed.

Yes, that is probably the best solution. The 12v batteries that Tesla use are known to die after 2 or 3 years and many do end up with cells shorted so it just pulls down any booster you attach to it - you are better off disconnecting the old one and connecting a 12v supply.

If so, is it best to keep it plugged in on the USB (not 12v as it's always live) inside the glovebox permantly to have a perm charge?
If it is a lithium ion battery based booster then it is the same as your phone, laptop or Tesla (without an LFP battery) - you don't want to charge it to 100% and leave it as it will damage the battery. If it is lead-acid based then yes you would want to give it a perm float charge. But normally the 12v battery dies went the vehicle is parked up so you won't be able to access it if it is in the glovebox.
 
Jeez, what a debacle! It’s abundantly clear that charging infrastructure is not the only thing in need of urgent attention. the recovery industry needs training and updating quickly.
It strikes me as appalling that Tesla would send anywho doesn’t carry the the right kit.
I shudder to think how bad it could have been on a dark country lane in the middle of nowhere and certainly shows up shortcomings in the design of the electronics
it’s a very welcome warning, sadly at the expense of @Mr Miserable who doubtlessly lived up to his name at the time.
My pucks will now live under the bonnet not in the boot and I’ll fit the tiny 12v battery for emergencies.

My brother-in-law broke down 100 miles from home on the M11 just after Christmas. The idler pulley came off his 1 series BMW. He was recovered by a flatbed within 30 minutes and arrived home less than an hour later than intended.
He had to come to us in an emergency and used the old BM because his i3 wasn’t fully charged.

I hope it turns out OK for you
 
A flat battery leading to a dead car is not unusual.
What is unusual and unacceptable is that there is no warning and that without a 12v battery the car is useless.

I have a Morgan Plus 8, it needs to be kept on a trickle battery charger when not in use for more than a week as if the voltage drops below 11.2v the car computer will not allow a start attempt.
BUT it has a voltmeter and through the remote for the alarm/immobiliser I can check the battery voltage at any time.

This makes me wonder if some sort of voltmeter should be included in the Service Menu, like the tyre pressure monitor.
Or should I fit trickle charging wires to the battery that are accessible from the bonnet compartment, so I can periodically check voltage and charge if needed?

If that happened to me at Amesbury I'd have abandoned the car and got SMBO to pick me up, but it is 11 just miles from home.
