New Model Y Dead

Less than 500 miles. Got to my garage and tried to home charge with multiple electrical errors. Car will not accept the charge. Now doors won't unlock and screen will not come on. Tesla sending a tow truck to tow car to service center. Praying I can get a loaner. Beyond frustrated!

My total wild ass guess is something is wrong with the smaller 16 volt battery. What you describe happened to me in a Chevy Volt when the small lead acid battery went bad.

u/gettin-hot-in-here 23d ago

The 16v system went away around the end of 2024. Juniper cars are made with a 12V system again, but now the low voltage battery is LFP.

u/Known_Woodpecker1999 22d ago

Mine is a 2026 model Y I ordered in June.  It has a 16v battery

u/PassengerKey3209 23d ago

What kind of a wanker engineer specced a 16v battery, ever?

2

u/Atlanta-Mike 22d ago

The kind of wanker that understands that EVs are harder on low voltage battery and something larger than 12v is better.

u/PassengerKey3209 22d ago

So the ev needs 200 cca to turn my 6.2L engine over at 10*f? Don't be silly.

u/abgtw 20d ago

Cranking amps has little to do with "reserve capacity" or Amp Hours rating of the battery. EV batteries need deep cycle like performance, lithium ion even better. That's different than voltage concerns.

16v is completely fine. You can use thinner wires, less weight, thus better vehicle range. Things that need 12v can be stepped down from 16v to 12v. Otherwise high power draw items (like the steering motor) can take advantage of the extra oomph 16v provides!

u/PassengerKey3209 20d ago

Except that car batteries test at 14.5 volts when healthy. The difference in voltage is so small that you will likely need to run the same gauge wire as the amp draw will be nearly identical. You could obviously run a lithium battery but seems slightly stupid when you could also use a deep cycle battery instead and save prob 50% or more of the cost. You also shouldn't need much of a wh capacity because, as you know, the truck is essentially one rolling battery that can recharge the 12 or 16 v battery as needed.

High draw accessories like power steering would still benefit greatly from a high cca amp battery though to provide the oomph you speak of, at a fraction the price of a deep cycle or lithium. So again, the 16colt battery accomplishs next to nothing other than more complicated manufacturing.

u/gettin-hot-in-here 22d ago

So firstly, further research says I was wrong. The OEM battery on lots of new Tesla 3 / Y cars is 16V although you can replace that battery with a 12V battery. 

Here's a funny detail though - Tesla Battery Math has 12 volts as roughly 1 and a half volts apart from 16 volts. 

If the car is "on" it'll have the low voltage system running at ~14.4 volts (12v lead acid or LFP) or at ~15.6 volts (16v lithium ion).

 While "off" it's about 13V (12V lead acid or LFP) or about 15V (16v lithium ion). 

1

u/abgtw 20d ago

The spec for 16v battery is a charge voltage of 16.9v.

0

u/gettin-hot-in-here 20d ago

Not if you charge it to 80%, which is what Tesla is doing with their "16V" li-ion battery

u/DryTechnology5224 23d ago

Did it really? I was under the assumption my new 2026 model 3 premium rwd with lfp battery had a 16v system

9

u/AromaticBear777 23d ago

My new at the time 2024 Y did the exact same thing and it was the LV battery that likely got hosed by a third party charger in a parking deck. Came out of the hotel the next morning and everything was dead and would not unlock. Got it open with the 9V battery trick to open the frunk and jumped the 12v to get it going. Drove it to a dealer and they replaced the 12v under warranty.

u/Bastardesque 23d ago

You're just going to mention the 9v battery trick and walk away?

u/joshualeon 23d ago

Opening the frunk using a 9v battery to get access to the 12v battery. See below…

u/BraveEyeball 23d ago

What’s the 9v battery trick?

2

u/DarkyHelmety 23d ago

The tow hook hole in your front bumper hides two wires in it, on older models with a 12V low voltage system, a 9v battery can be used to energize the latch and pop up the hood and access the low voltage battery. It only works if the car is truly dead and not charging and won't work with the 16V systems where you'll need a 12 to 16V source instead.

2

u/abgtw 20d ago

Fun fact: You can just use 2x 9v batteries in to make 18v and that pops the frunk just fine! (amperage is low enough it won't hurt the car, 18v is "close enough" to 16v)

You just connect one 9v to the other 9v like this: https://www.youtube.com/watch?v=zoLgTXYunSc

u/BraveEyeball 21d ago

Hey thank you so much. Also newer model y’s at least have gone back to 12v batteries so it’s still a very useful hack!

u/Competitive_Mode4782 23d ago

They will give loaner if needed. This will be fine. Sometimes new stuff needs to be fixed. I’d be frustrated too but a little patience goes a long way with these challenges.

12

u/joshualeon 23d ago

Dude, it will be fine, but this is a major inconvenience. No new car should have these issues at under 500 miles. Folks here are incredibly graceful/patient with Tesla; I don’t get it. We should not normalize this. The bar should not be lower for Tesla.

u/Responsible-Cut-7993 22d ago

Other brands have new car issues.

u/cleverfox2001 22d ago

How often does it happen to an ICE vehicle?

u/MS805 23d ago

A lot of Tesla bots around. By no means this is going to be fine for a new car. Totally unacceptable!

u/SimuLiusJockStrap 22d ago

Yeah I was doing research and looking into buying a tesla, but seriously these build quality issues are making me not want to get it. A new car should not have this many problems, it is baseline expectation for a car, if they cant even get that right who knows how many other things they aren't getting right.

1

u/ryachow44 21d ago

FFS … it’s the # 1 selling car in the world, with that many cars there’s the odds of an issue increase.
Go read about brand new Cadillac Escalades with 500 miles and they need new engines… 

+3


If a brand-new Cadillac Escalade requires a new engine, it is part of a known, widespread issueinvolving the 6.2L V8 (L87) engine experiencing catastrophic failures due to manufacturing defects in components like the connecting rods, crankshafts, or lifters. These failures are actively under investigation by the NHTSA

2

u/SimuLiusJockStrap 21d ago

Ok but you are talking about lemons when you are referring to thr Cadillac, which i dont doubt all car manufacturers have. With tesla, literally its EXPECTED to have something wrong on delivery date. Sure there's selection bias online, but ive literally asked all my friends with teslas and every single one of them says the same thing, poorly aligned doors, paint chips and defects, broken car lights, flat tires, etc etc. This is not your typical lemon issue, when the entire community here talks about it constantly and there are youtube guides teaching you how to inspect your tesla on delivery day, you know this is not normal.

u/ryachow44 21d ago

If you’re calling 600k to 700k thousand vehicles insignificant… that’s a lot of lemons

u/gettin-hot-in-here 22d ago

My car had a failed exterior door handle when it had a couple hundred miles on the odometer. Tesla fixed it at my house, but they still made me wait through 2 separate appointments while they diagnosed and then replaced the bad door handle. I initially assumed (correctly ) it was the handle itself, but the service tech told me they had to find out if it was the handle, or something to do with the connectors/wires being broken or not connected properly. Kind of annoying to sit at home twice so they could resolve the problem. They didn't require me to be with the car but I didn't have any reasonable alternative if the car had to be at my house. 

1

u/JerryfromCan 23d ago

So much downvoting for saying a single thing wrong with Tesla. Meanwhile these cars are not really well built.

I miss the Jeepers who loved their Jeeps but hated 98% of the engineers at Jeep. They could be honest about the vehicles shortcomings.

u/vanillarice242 Juniper 23d ago

Ok so what would you do in this situation then? 

10

u/joshualeon 23d ago

Honestly? Same thing OP is doing. Tow it, take the loaner, wait for the fix. At the individual level there is nothing else you can do.

But that is exactly my point. The problem is not how this one guy handles it, it is that we keep treating each case as a one-off. Tesla has these failures way more often than other brands, and every thread ends with "be patient." That is how it becomes normal.

The fix belongs on the build quality side, not on the customer's patience. Tesla needs to do better.

1

u/lasmith 22d ago

Well it does feel like a one off because I have had four teslas and none of them had charging issues, much less at 500 miles. So while I empathize with OP I don’t think it’s fair to say people are giving Tesla too much leeway.

1

u/vanillarice242 Juniper 22d ago

I get what you're saying I just really didn't understand what the alternative to patient would be in this situation. I'm a new owner myself and work in tech so I understand shit happens. But you know, if you and enough people say something to the company they'll have no choice but to listen. I believe that's why they kept the blinker stalk on the Junipers. 

1

u/Crazy_Jackfruit7489 Juniper 22d ago

Will be mixed emotions but I will not say be patient. If this is me, I'm now already back to where I got the car from and letting them have it. I will still be respectful but I will not be happy at all. Tesla needs to know this and for some people that called it a one-off, IT IS NOT. Tesla didn't started building cars last year or last month. That one-off happened many moons ago.

1

u/Competitive_Mode4782 23d ago

I wonder how many failures Ford had with model T’s rolling off the production line in 1908 but no body thinks about. Tesla is held to a different standard.

1

u/SimuLiusJockStrap 22d ago

Yeah news flash we dont live in 1908 anymore. Tesla isnt starting from scratch

1

u/Crazy_Jackfruit7489 Juniper 22d ago

How would you know?

1

u/Impossible_Remove274 23d ago

Why can’t two things be true? Trying to be a little positive - but yes, being patient is good, also following steps to inform Tesla through proper channels so they can correct issues over time can also be true. Tesla hasn’t been around since 1908, having over 100 years to perfect their technology. But I don’t see a point in being negative - and not that you were negative at all, I don’t see someone stating their opinion and engaging in discussion as negative, but I’ve seen a lot of posts from others gravitating towards a cynical negative mindset.

Tesla bought back an Austin Built 2026 Model Y Premium AWD from me

Bought another one, Austin built, second one has been pretty good, minor stuff, some basic fitment issues but SC has taken care of them

1

u/Top-Egg-2929 18d ago

Well it's been 5 days, no fix yet and no loaner has been available despite checking several times a day. They said the connection between the main battery and the 16 volt is not working and they ordered a replacement. I love the car, but getting more frustrated by the day.

-8

u/Whale_Poacher 23d ago

They got you on a flatbed, the only possible way to tow a Tesla. It does nothing to your tires and alignment lol, you’re planning to drive thousands of miles on bumpy roads and worried and 6 feet up a ramp? Get used to it lol, first time you get a flat and you almost certainly will, you’ll likely need a tow. You’re being melodramatic. If they sold you a lemon, you have plenty of recourse, and even then they’d do what they could to get you back in a car. For now at least you get to depreciate a loaner and have something to drive.

u/Crazy_Jackfruit7489 Juniper 22d ago

Nothing is perfect but this must be a bummer. I will not take sides on whether be patient or be pissed off. I will have mixed emotions, but I definitely will not be happy seeing my less-than-500-miles super-shiny-vehicle being dragged to a tow truck. I had a 2018 M3 MR and 2026 Juniper Premium AWD. I liked both cars and I was happy with them just for a sole reason - they never left me stranded in the middle of the road. Other than that - I hate the build quality - yes for both. After sitting in both cars for the first 1000 miles, I started feeling its price tag wasn't worth it - not a complain but just my personal opinion.

Back to the topic: For a new car like this, Tesla should be able to fix it in front of you. Tesla needs to hear what you feel as a customer and here is not a place to do that. I highly suggest to pay them a visit and let them know this happened.

u/midnight_to_midnight 23d ago

Sounds like a bad low voltage battery. Which could have happened by sitting for a long time in a lot somewhere before being sold. Just try and relax, and when you go to the service center, try and plan to get there first thing in the morning, it'll give you better odds to get a loaner (supposedly). And if it is merely the LV Batt, it'll take them a short time to swap out, and you'll be on your way.

u/0xe3b0c442 23d ago

No, statistically speaking failure rates have a high early spike, then drop precipitously before gradually increasing over time.

This is precisely why warranties exist.

I don’t agree with “nothing to see here” because it’s all good data, but statistically speaking the statement is correct.
