I have a MY with the lithium battery and HEPA filter. Just wanted to note that you don't have to remove the frunk bucket to get the filter out. Just remove the two bolts on the sides of the filter assembly and you can wiggle the whole thing out. I've done it a number of times when adding after market electronics to my vehicle.
You're missing out on a wonderful experience. This guy tackled this problem completely wrong btw. There are other videos that explain how to (simply) resolve this issue.
Just an FYI. I received the bad 12v warning on the dash but it ran fine for several days with no problems. Finally one day the only thing that would not work was the video screen. Fortunately, by doing the steering wheel reboot two times - it rebooted but the 12 V battery warning was still there. I took it to Tessa Service and they replaced the battery at no cost. And mine was the Model Y LR, 2020.
Feels like you could have just let the Tesla mobile service deal with this given that they replaced the battery at your home anyway and you already had notifications that it was the 12 volt battery that was causing all the drama. I personally wouldn't have bothered messing with the car like that if it was still under warranty.
Tesla wanted me to bring the car in to service, which was only possible on a tow truck. It was only after I rebooted the car that the mobile service was offered to me as an option.
when my Model 3 hit 4 years old, I went to service and got them to replaced the 12 volt battery, no appointment. I don't want the hustle of the car dying on me.
So bad. Properly cared (charged in the correct way - you have so much power to charge it with in the car) it should last you 10+ years. Can not understand how they can be so bad at maintaining the low voltage battery. Like they do not have any BMS at all for it.
Classic 12V Battery dying. The reason only half the car is working, is because of the dead 12V, the DC-DC converter can't get the voltage high enough, so only a few modules in the car start up properly. For example in your case VCFront right did startup, wich made the right side doors and windows work, VCFront left did not have a proper startup, so the horn and headlights did work, but not the doors and other functions. For the people claiming that their ICE car won't have this problem: This is not a Tesla problem, but a new car problem. I've seen plenty of ICE cars that started to behave funky if the 12V couldn't hold charge anymore. The only difference is that you have to disconnect the first responder loop so the DC-DC comverter stops, so you can swap out the 12V battery...easy fix. Great video btw, no hysterics, just logical problem solving.
This is really bad and some small design changes could have made this so much better. For instance: 1. Make it easier to reach the battery terminals! Ridiculous to have to tear half the car apart for it. They could have been easily reached in the frunk. 2. If the battery charger was supplying power to the car so it would not start working properly, then why the heck can it not give enough power to get the car opened?! 3. Unlocking the car like you did with a stick means that you can easily just...unlock the car if you break the window. If I lock our Volvo, it will disable the inside unlock/open buttons/handles. That way you can not open it even if you break the window. 4. The car has a battery charger. Then why does Tesla low volt batteries die so often? A lead acid battery can last for a decade or more without any problem if correctly maintained (charged in the correct way - that is why UPS batteries last for ages if the UPS is not used). Either they use really shitty battery quality or they are totally clueless on how to maintain a lead acid battery. Most probably both...I have NEVER had a battery in an ICE car go flat. Bad, yes, but you could always unlock the car but then maybe not start it in -20 degree C (yes that I had, but I could unlock it (with remote!) and pop the hood and then a charger for five minutes and off to go - yes, that battery was old and heavily used). 5. Do not overcomplicate things. Frameless doors solves a lot of problems, not just this one here where you can not close the door. 6. Once again: Do not overcomplicate things. Just put in a regular keyhole in one door. Once again, in our Volvo, in a somewhat hidden (so it does not collect to much dirt and shit) location on the driver door, you can just put in a real key and open the door. 7. Those nice error messages, why the heck did you not see them earlier? It should Really tell you that something is wrong in this case. Like, really clearly! Glad you could enter the car and get it to work, finally. But you should not have had all those troubles getting there.
What a pile of junk. That’s so stupid. A gas powered vehicle, well, just hook up the jumper cables, and done. Perhaps a simple unhook of a better terminal for a few minutes and a reconnect? But, wow, what a joke!
In this case I needed to reboot the car by disconnecting both power sources. You can do this by disconnecting the negative battery terminal and unplugging the first responder loop, both of which are located under the hood. Should take only five minutes.
@@SuperchargedTravels got 3 diesels 1 gas.. over 5 years now.. havent replaced singleone, all going strong. Lead acids get messed up if people dont take care of them.
@@mingiasi "Pushing a battery longer than five years, even under perfect driving conditions, could cause your battery to fail without notice. For that reason, many manufacturers recommend a replacement schedule of five years." Source: www.autozone.com/diy/battery/how-long-should-a-car-battery-last
@@SuperchargedTravels Nothing lasts forever that's for sure. And they do lose some capacity over the time spent in use. I'm yet to see one "fail with out a notice" on me yet and i have dealt with all kinds of lemons.
The fact that you were not freaking out and remained calm throughout....IMPRESSIVE! I would have been screaming about stupid design and good for nothing Tesla! Good going! But, how did you know all of this?
@@-jackinspokane6648 You say that also when the car is out of charge in the high voltage battery? Or in a shop because of an accident? People and their own truths.
The last car I would ever buy in this lifetime probably wouldn't take the gift of the piece of sh*t. A million things can go wrong. My 2012 $13,400 2012 Nissan versa is running like a fine Swiss watch 115000 miles gets 39 miles a gallon and have only replaced the brakes. That doesn't include bursting into a 4500 degree fire bomb hope it doesn't happen to you.
In 2021, there were around 174,000 highway vehicle fires reported in the United States. Hybrid vehicles, which have an internal combustion engine and an electric motor, had the most fires per 100,000 vehicles (3475), while vehicles with just an internal combustion engine placed second (1530 per 100,000). Fully electric vehicles had the fewest: 25 per 100,000.
Older vehicles are more likely to catch on fire than newer ones. Vehicles that were 10 to 14 years old accounted for 23 percent of the fires, while vehicles that were less than five years old accounted for only 9 percent.
How the he'll did you learn to troubleshoot this problem? I am so impressed with your work. I would not have known where or even what a DC to DC converter is, much less where it's located. I can see I have a lot to learn. Let this be a lesson to all of us that advances in technology can bring new problems. Kudos to you, sir, for diagnosing the problem, troubleshooting possible solutions and remaining calm .
Designed by engineers who have NEVER serviced a vehicle of any kind. And just why is that auxiliary 12v Lead-Acid battery dying? I fear the LIon will do the same thing after a while.
12V car batteries die. Mine lasted four years, which is smack in the middle of the 3 to 5 year expectancy. knowhow.napaonline.com/average-car-battery-life-time-change/
Same thing happened to me on my 2019 M3. I have a 9 volt battery tied to the wires in the emergency frunk port so that I can open the frunk should this happen away from home. I had a battery charger (from my ICE days) and used it to charge up the battery after disconnecting it. The car gained enough charge to work normally and I drove to the service Center and got the battery changed. I think I could have purchased a new battery and changed it myself. There are instructions for doing that here in RU-vid.
I had the 12 volt batterygo out onmy 2018 blue Model 3 also. I was able to drive mine to theTela service center where they replaced it under warrenty apso,
Normally I like on-screen manuals but when the batteries are dead, how do you read the manual? The door latch is really a boondoggle. @@WanderlustWonderscape
I believe that the first responder loop would do the same thing... but I haven't confirmed this. It will disconnect the high voltage, which would essentially do the same thing. It also disconnects the air bags and other such things, which is why I don't want to experiment with it.
I think the fireman's loop is on the interlock that flows through the contactor, dcdc, on board charger and inverters (motor electronics). They all have little switches on the access panels that if they are opened disable the contactors.
This gave me quite a chuckle! See how far we have come in vehicles? I have a 1969 IIA 109 MilSpec LandRover with a diesel, it doesn’t need electricity to start, open the doors or windows. The engine and power train runs quite happily with out any sort help from pixies. I only have an electrical system for lights and wipers, the engine has a crank handle or air starter.
Your car was still under warranty even though its a 2018? Also what if both doors would not open? How would Tesla service guys get into the car? Did you call Tesla service and ask how to open the doors?
Now, let's imagine a mom with two kids in the back in the middle of the night, and it's raining. And she bricks the car, with the kids inside. No phone, no charger miles away. NO, thanks.
So the children are not valuable enough for you two jokers; OK, then imagine she had two dogs inside of the bricked tesla... maybe in july, at 110 degrees?
Is it a normal lead acid 12v battery in our cars? If so, I wonder if it would be beneficial to run a battery tender lead from the battery and have it sit just under the hood on the plastic cover.
I don't think it is. Regular led acid battery is for staring an engine. You can draw a lot of current from it, but it does not like getting a deep discharge. There is an other kind of led acid battery that is for golf cars or for UPS that would be better suited for a tesla.
'Hey, my car won't start... let me take the car apart so I can find and access the battery'. Another reason to have an emergency key so if the 'turn it off, turn it on', universal IT solution doesn't work you can at least get into the vehicle without looking like you're trying to steal it
Just had a similar problem with a Model S. The handles would not come out and the only thing that worked was the front latch. The car is not mine, and I had only driven it once, so had no idea what to do. The owner was on a plane so I could not speak to him either. Eventually the front passenger's door handle popped so I could open it. That was when I found out about the frameless window. When I managed to get in touch with the owner 24 hours later (a long flight) he contacted Tesla who came out to the car and replaced the 12 volt battery. Unfortunately the car had been sitting for 2 days with the passenger door partly open as I could not get the window to go down to shut the door. This was during two days of very heavy rain in England so the car is now soaking wet inside.
4:44 - I was able to vent the windows on the right side of the car using the app, and then I used a long wood stick to open the door electronically from the inside.
i really like to tinker with my phone, and it being an android with the ability to unlock its bootloader i can brick without too much efford if im doing something stupid.... and now im scared to think how id ubrick a car if i mess something up. i'm guessing i cant plug it into my PC and flash the OS again, can i ?
@@SuperchargedTravels Not at the rate EV’s do. Data has shown that EV’s have a reliability rating of 20%, while gas cars is 80%. Gas cars do not require 500,000 of material to make 1 Tesla battery, gas cars fill up in less than 10 minutes while EV’s require at least 40 minutes. When gas car batteries fail it’s $150, while EV’s is $30k. EV’s tires are significantly more expensive. This is why Hertz is selling all their EV’s and American’s are not buying them. GM, Ford are losing millions on EV’s. For example, in NYC there are 2 million cars, 1% are EV’s. I can give you many more facts. Do your research boss.
@@josephconsuegra6420 In Norway, where they have extreme cold conditions, the road assistance company Viking reported that they responded to 34,000 requests in the first 9 days of this year. 13% of the calls were electric vehicles and the remaining 87% were ICE cars. Since 23% of the cars in Norway are electric, this makes them twice as reliable. Source: www.tv2.no/nyheter/innenriks/klart-darligst-i-sprengkulden-helt-ekstremt/16370146/ You don’t “fill up” electric cars. If you have a place to plug-in overnight or at work, the charge time becomes irrelevant. For those times when you go on a long road trip, a supercharge from 10% to 50% will take ~10 minutes and to 80% will take ~30 minutes. For example, a road trip from Los Angeles to Las Vegas would only require a 6 minute stop in Baker, and this is a slower v2 supercharger limited to 150 kW. Source: abetterrouteplanner.com/?plan_uuid=9a7f8b0d-f2f6-4c0c-9ceb-35432ace2e0c Both EVs and ICE cars use the same 12 Volt batteries that fail after 3 to 5 years (exception: The Cybertruck uses a 48 Volt battery). The high voltage battery is designed to last 300K to 500K miles, which is 20 to 33 years at 15K miles per year. The warranty on a Model Y LR is 8 years or 120K miles (70% battery capacity retention). Tesla has no problem selling cars. In 2023, the Model Y was the best selling car in the world, including ICE cars, selling 1.06 Million units, a 57.1% increase from 2022. And this is only the Model Y. The Model 3 is also a top seller. GM and Ford are losing money because they don’t have the manufacturing efficiency advantage and experience that Tesla has. Tesla is one of the most profitable car makers in the world. They make cars in America that contain the most American parts of any car you can buy.
@@SuperchargedTravels It takes 500,000 pounds of material to make 1 Tesla battery. Your EV “facts” are laughable. Tesla has lowered prices since no one is buying them. Hertz rental cars is selling all their Tesla’s and replacing them with gas vehicles. Elon claimed it was #1, but in actuality it’s Toyota. In NYC, they have 2 million cars, only 1% are EV’s. EV’s are good for small population centers in European countries since commutes are short distances and European’s are easily misled by feelings and Thunberg fantasyland statements.
They do not. However, you can watch "how to" videos using the app or in the car using Tesla theater... and, of course, online as well. You also purchase the car using the app. Much better than dealing with a car dealership.
@@SuperchargedTravels that is true, I do watch tutorials on how to take stuff apart. But I rather have a physical manual to read because I don't have to zoom in like on a phone to read text and it just over all feels better.
The warranty is "4 years or 50,000 miles, whichever comes first", so no... you are not under warranty. I would suggest you look into replacing it yourself. It's not that difficult. Here is a video on how to do this: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SZJJNOa3Ju0.htmlsi=5qDYbxVimRTLAcuS
I missed the warning, and three days later my car was unresponsive. I think the Lead Acid batteries are very different than the Li-ion batteries in terms of reliability and providing enough warning.
Yes, the voltage was 12.7 Volts when I measured it. But that doesn't mean much as the car had not been used for several days. The 4-year-old lead acid battery needed to be replaced. Once this was done, there were no further issues with the car.
@@SuperchargedTravels I wonder if putting a 12V battery charger on the failing 12V lead acid battery for a couple of hours would have done anything? Good job going through all of that to get the car to completely reboot.
Seems like it would've been better to just wait for Tesla service 😅. That said, this is why the Lithium Ion 12v is so much better. It's not just that they last much longer, but they can warn you about battery health much sooner than they can with the lead acid battery so that you have plenty of time to get it replaced.
There is no reason whatsoever that this should happen if you know how to measure and take care of the battery. A lead acid that you handle the correct way will last 10+ years without problem, and you will know when it is time to replace it. But Tesla just have no knowledge about it it seems, and/or they use the cheapest shit quality batteries.
Exactly. And having over a decade on you, when something goes wrong, you and I roll up our sleeves, we don't expect an app or online update to do it for us. I'm concerned today's youth often don't have the mechanical knowledge to get around digital problems.
@@Pandypanda1234 Everything they have is app delivered. Hailing a cab/uber, food, entertainment, doctor visits, and hell even dog walkers. Once the current blue collar workforce retires, they are going to be screwed.
Ah, I thought there was a reason why I never ever want to own a Tesla, or any other EV come to that. In my 53 years of motoring, I've never had this kind of problem with any of my ICE cars however old or crappy they were.
This issue does not have anything to do with this being an electric vehicle. This a combination of failure of the 12 V Battery and doors without mechanical handles. There is a variety of ICE cars with the same type of doors. However, legacy car maker usually think about a backup plan. My car (EV by Volkswagen) has a door handle which is operated electronically but has a mechanical backup mode. Tesla does not.
@rklein because we like seeing the kind of pain tesla or any ev owners have to go through to do simple things that have been made unnecessarily complicated by these pieces of terrible engineering. Case in point, opening the hood. Why the heck should you need to supply power to it to open it if it has no power? On almost literally every vehicle since time immemorial, it was a simple mechanical latch. Same thing with the doors. You would have to be an idiot to buy one of these things since all it takes is for it to run out of power and you could no longer have access to anything in there. Like what if your wallet, phone, or PASSPORT was in there and you needed it. Oops , let's find you a 12v power supply somewhere to open the hood to find something else to open the thing so you can then open your doors. Screw that.
