You’re more likely to respond to such a survey if your battery fails. This survey is suspect at best!
Really depends on who filled it out. Some could say that because I shared it out on Twitter that people who are extreme Tesla fans are more likely to fill it out.
Agreed.. or have a axe to grind.
I don't really get this line of thinking.
Because they're fans of Tesla their batteries don't die? Or they're willing to lie about their battery status to pad the numbers?
What does being an uberfan of Tesla have to do with the results?
No sh-t. Great point. I have owned a Model X since 2016. I have lost about 14 miles of range with 70k miles.
@@AllThingsEV I'm sure there are no Tesla haters on Twitter that would provide false info lol
Hi Sean. I like the effort, and contributed to your data points as one of the “failures”. However, there are some scientific gaps in the methodology and reporting. As others have mentioned, sample size is too low and owners with failures may be more likely to respond (like me). Further, the total number of cars on the road (and cumulative miles driven) vary greatly between models. I recommend attempting to normalize the data to glean more meaningful results. Also, I’d love to see data on how much people paid to have their batteries repaired or replaced. For me it was $0, covered under warranty at 80,000 miles. My car is almost to 140,000 miles now and the replacement battery is holding up well. Cheers!
Thanks for taking the time to fill out the survey and your comments here. I'd love more data - and that's partially why I decided to publish what I have now. I'd love to do another snapshot at 1,000 entries.
@@AllThingsEV it might be worth contacting tesla's service department or some of the tesla owners club organizations out there to get some assistance in the data they may have available.
@@AllThingsEV I would guess 100% of those are under warranty since Model 3/Y are all within 8 years/100k miles (lowest optioned) still and S/X older are unlimited warranty.
I agree. I do not think you can make a conclusion about the failure rate by model without knowing how many were sold -- What is the population from which these anecdotal results come? Another question is, what is the definition of failure? And is everyone using the same definition? On a more positive note (for me anyway), I see no 70 kwh batteries in your slides. I have a 70D so that seems like good news, but it may just be that the 70 kWh batteries were not sold for long (they were replaced by the 75s fairly quickly. I think).
You could normalize this data by using the total units of each model sold to get an estimated failure rate per 1000 units sold for each model. You might be seeing more reported failures for model S 85 because many more of those models were sold. So for example if you knew 1000 MS units were sold to date, and you had 100 people who responded to the survey and 10 reported failures, (10/100)*1000= 100 battery failures/1000 units sold
It might also be helpful to adjust for the average age of the fleet of each model. If there is a distribution of cars sold over years you could calculate the total vehicle years for each fleet, so for example if a model had been available for sale for 5 years and and 1000 vehicles were sold each year than you would have 1000*5+1000*4+1000*3+1000*2+1000*1=15000 vehicle years.
Combining both of the above calculations you would be able to arrive at battery failures/unit sold/vehicle fleet yr.
I wonder if owners with battery failures are more likely to fill out a survey? 7% seems super high.
that..also sample size is too small to be meaninful
Yeah, highly doubt Tesla would let a 7% failure rate fly for one of the most critical components of the vehicle.
A better metric would be battery failures per miles driven.
I had a (very short) conversation with someone whose “sister’s girlfriend” or “girlfriend’s sister” had to spend 23,000 replacing her Tesla Battery Pack. When I asked “how old was the car.?” Answer: 4 years. So I called “Bullshit”, mentioning that the warrantee was 8 years. . . That’s why the conversation was short.
Even if going by miles that means she would have been driving twice the average miles of a typical driver. Possible? Sure.
But that would also go against their narrative of wanting to make it seem that needing to spend $23K is something the typical driver will face.
Maybe they meant they owned it for 4 years? - that seems more plausible. Or yeh, they could just be lying, you have your religious zealots on both sides.
We have about 32,500miles on our Model Y long range AWD and our range is currently at 298miles. This is about what I expected for range reduction when we bought the car in July of 2020. Still look for excuses to drive it. Love this car.
Fantastic! I just got the same car 3 months ago, loving it.
I wish Tesla would publish their stats on battery and motor failures in the spirit of transparency to built brand credit and trust.
It will probably scare the living daylight out of any potential owner :) - so they keep to degradation stats, obscuring the fact batteries generally outright fail once they've lost 20% range, this is entirely hidden in all their materials and makes it seem that look, we have some batteries at 300k miles with 18% degradation - well, yes, but what about the hundreds of thousands of batteries that failed before then, that still showed 87% capacity remaining right up until the day of failure?
Because they fail way to often. The used Tesla market would crash.
The sample pool is too small to be relevant with the millions of Tesla's out there...
No it's not. The total number of cars has nothing to do in the calculation of standard deviation used to determine the relevance of a sample pool.
How were sampled owners selected?
@@romainhedouin Maybe unhappy people filled out the survey more often?
Wording of the survey most likely introduces an even stronger selection bias toward failure. There is already a selection bias that people with complaints are more likely to talk.
Get me more data. Share out the link and I'll do another video.
240.000 miles. 7 years old 85D. Still on the original battery and dual motors.
Outstanding!
Please fill out the survey if you haven’t already!
Done
I live about a mile from a Tesla service center, when I pull in to use the supercharger about twice a week I enter from the back and pass by the dumpster. I’m always surprised how often I see an empty wooden box that is shaped like a battery. To me that 7% might be right.
Feedback: I have 10x Teslas of all sorts in my company since 2019. out of those only one Model X with 95.000km had an issue. Tesla SeC gave me a complete new Batt , instead of a refurbed one, which was cool. It took them almost 3 months which wasn’t cool.
3 years and your own anecdotal failure rate is already at 10%, which is horrible
@@xuanzheng1049 you don't seem to grasp what i wrote. so pls allow me to explain: i did get a BRANDNEW battery within warranty terms. So this new battery free of cost for me extends the lifetime of my car dramatically as the motors and drivetrains almost never fail. Should i complain about getting a new batt? NO 😂
You don't seem to grasp how battery failure works. They don't just fail when thwy are in warranty. Elons said the would last for 300-500.000 miles. They don't not even close. So when the warrenty is up the cars are trash. Imagine buying a 25k$ used Tesla and shortly after having to pay 20k$ for a new battery 🤣
@@TheSanien seems that you are the real expert: You know that 95k km is WITHIN Teslas battery warranty coverage right?
Compared to the GM Bolt...
7% failure rate is something they aim for by 2045....
Yes, I think maybe 2045 or 2050 will be when EVs become a viable alternative to non-EVs, assuming another technology doesn't come along. The synthetic fuels and hydrogen looks interesting, no 70% losses getting your energy from the grid to the power socket, no need to rework the whole infrastructure of the country, no need to boost the energy supply by orders of magnitude, no daily 1% self discharge, no inefficiencies due to suboptimal temperatures, no battery degradation, significantly more cost effective in all aspects, much larger range, near instant refuelling, etc, interesting times.
A good time to do an update on this, been seeing some failures for out of warranty customers since there are a lot more used Tesla’s in the market.
My 2019 Model S Dual just failed with 49,099 miles on it. Had an 8 year unlimited mile warranty.
I would like to see a category on what mix of supercharging and low voltage charging was done per survey.
Okay!
The bottom line is no Tesla model is a car you can keep reliably after the warranty. What I mean is inevitably you will need a battery; probably sooner than an ice car needs a motor. Probably something like a Lexus. Charge cycles only last for a specific amount of time.
Roughly 3000 full cycles for an EV battery, at least the original Li type (not newer LFP). Sounds limiting, but if 200 mile range, that would give you 600K miles, which is longer than most gasoline engines last. By then, there might be cheaper, battery retrofits (solid-state, sodium). Prius owners found battery replacement wasn't the horror originally feared. If you keep charge 20-80% and never Supercharge, might get even more usable life.
It would be a mess to get into it but i'd be interested in a breakdown of the failures by year/major design iteration. eg 70D and 100D in same gen vs 60/85 older gen
I have 20K miles on our 2020 Model Y dual motor.
Thanks for your videos and information. Please find a different intro music.
Thanks for the input! Please fill out the survey if you haven’t already.
This is way to small of a sample size to gather any conclusive data. It also is worth pointing out that people who experience issues are far more likely to go out of their way to make not of it. You also don't specify the details on what you consider to be a battery failure, is it referring to a battery that falls below 85% of its original capacity? There is also no consideration for the amount of the included vehicles with that specific battery configuration in circulation.
I'm looking at used Tesla Model S's. On dealer lots, is there some way of determining if the original battery has been replaced? Say... by a dated sticker on the battery or by menus giving a newer date or lower miles than the car's date or miles?
What was the selection process for members of the sample? If just voluntary, then any who had a failure are FAR more likely to respond, making your result completely meaningless.
If that is not fixed, you must be catagorized as a FUD source.
It was sent out on Twitter and several Tesla owner Facebook groups.
@@AllThingsEV
I would suggest the point still stands.
Owners "interested" in pack failure would be far more likely to either search for or take interest in a mention of pack issues, the majority wouldn't even go there.
@@rogerstarkey5390 To play Devil's Advocate, since this was shared out to ultra Tesla owners and fans, one could say I only received feedback from people only willing to say great things about Tesla. Someone could say that failure rate is much higher because of who filled it out.
@@AllThingsEV I dont think human psychology would bear that out.
No failures on battery or motors for my 2015 Model S 70D. 161055 miles on the odometer. Added info to your Google docs survey.
Nice!
Great job, really appreciate the effort in setting up this survey and analyzing the data. As others have pointed out, there's likely a huge reporting bias of tesla owners with failed batteries encountering your survey and filling it out. Nonetheless, thank you for your work!
The data is a reflection of the sample set. If you’re not happy with the sample size, fill out the survey and I’ll revisit the data:
docs.google.com/forms/d/e/1FAIpQLSdCaOjd9X200MleVvGrUTNOVj2FlfclD3-TQfvtnyYB7AAF8g/viewform
I think your sample size is way too small. Likely those that have a battery issues are more likely to be online searching, vs non failed cars and owners just living life and not looking for surveys to fill out.
It's possible. Although, the opposite could be said as well. Some could say I only sent this out to the most raving fans of Tesla on Twitter and the rate of failure is low. This is why I invite any Tesla owners watching this video to fill it out. I'm happy to do another video with more data.
I'm curious if the battery degradation affects both range AND performance? Meaning will a high mileage Model 3 showing 270mi of range now also have a corresponding drop in it's performance?
As so many others have noted the sampling is not random so the data isn't really very useful. I did fill out your survey though. Would be more interested to know the percentage of failures based on the percentage of respondents. In other words, if 30% of your responses were long range model Ys, were 30% of the failures long range model Ys?
Appreciate the feedback and survey data!
I didn't realize the failure rate was so high, that sounds crazy, but luckily the failures tend to happen within warranty. I had a MYP from new to 70k mi and had no mechanical issues the whole time, and I was mashing the gas on every single drive
If you see my post above, I really would ignore the risk of failure as it is small. Just carry on enjoying the car!
They tend to happen under warranty because these cars are probably mostly still all under warranty. If every car tested here had exactly the same mileage the test would be helpful, but I'd bet 90% of cars tested have less than 100k on them.
We cannot assume the failure rate drops after 80k unless we know all of these cars have far more than 80k on their odometers, which I'm betting they don't.
Too small of a data set. Should contact service centers to see if you can collect more datasets
There aren't many third party ones for Tesla and Tesla themselves unfortunately hide this data from the public.
Amazing how many S/X batteries failed, considering many fewer cars were sold. Best to normalize by that, and also by age of the vehicle. Model S has been sold since 2012.
I drive a 2021 (June build) M3SR+ 26000 miles. It's been at the service center in Pensacola for 28 days and a battery ordered 42 days ago. Tesla has me in a rental (which I despise) and is taking care of me, however this is a service issue that must be streamlined.
Submitted survey.
Thank you so much! Really appreciate that!
@@AllThingsEV FYI Sean, I now have my vehicle, it was ready on 11-10-2022, 46 days after the hv battery was ordered. All is well now.
I have 70,000 mi on it my 2014 s model period after acquiring it shortly thereafter the rain shortened from 200 me to 50 and then a few months later after that all kinds of code stopped the car from even starting, which strangely did coincide exactly on the day after the Tesla service came to make me a new key.
2013 P85 126,000 miles on original pack. I think it’s gotten the 2019 software update that reduced its range. I believe that was due to pack fires. My max range is only around 230 miles.
Really great data
Sean - Mid-Range currently at 61,000 miles - life time Wh/Mi 281 - BMS OBD reading shows 58.9 usable still of 64kwh - Newer Battery health check ran at 60 degree outside - came back at 98%, pretty reflective of my 58.9kwh. My Long Range RWD 68,500 miles - Life time Wh/Mi 293 - BMS OBD Reading shows 68.1kwh of 73.8 - Battery health check ran at 58 degrees showed it at 97%, again super close to reflected readings I seen. Keep in mind both usable 58.9 / 68.1 are drivable - there is a buffer of 2.5/3.5 respectively.
That's great, but it's important to remember your battery pack may have 90% capacity remaining right until the minute it fails. It is very unlikely for a battery to lose more than 15-20% capacity, it is far more likely to outright fail at this point and this statistic if not available from Tesla unfortunately.
why don't you separate LFP from other packs?
Iv got 800.000miles on my 1962 impala replaced batery few times $80 a pop
Do I have to sign in to Google to be in the survey? If so, that excludes a lot of people including me.
No
Interesting. I don't see the sample size being large enough to draw a real distinction between 5% and 7%, but I'm not surprised to see more failures in the 3P. Having a high current draw on a modest capacity pack, especially a 2170 pack with less effective cooling and fewer parallel connections than a 18650 pack, strains the cells, may cause internal hot spots, and will quickly find any weak links. There is a reason Plaid uses 18650s.
Just like in ICE cars, flogging it has a toll on the power components. Performance models also do tend to be bought by people who will drive rapidly (duh). Driving rapidly, especially for inexperienced drivers who often have no formal on-track training, often leads to mishaps that could well damage a battery pack and require replacement. See the Rich Rebuilds channel for the Model 3 battery Tesla wanted to replace because of a cracked exterior cooling hose fitting.
Please share an excel file or crunch the numbers yourself to break out failure by age. Age and cell chemistry generation has an impact on cell life. Tesla iterates quickly and shares hard data sparsely (as do all OEMs). It is entirely possible that certain years, months, or batches are more prone to failure after some number of miles or some number of years. Tesla has only been in real production for ten years. There will be swarms of battery replacements needed (or good cars scrapped) in the coming decade.
Sidetrack: Most OEMs are now moving toward modular pack construction that has a design intent of allowing repair of the battery pack at some future date, rather than requiring full pack replacement. It is telling that Tesla is moving in the opposite direction, gluing everything in the pack solid, utterly preventing repairs or reuse of the pack's components. One shorted cell now renders a "structural" pack utterly useless for anything but shredding and recycling. This is short-sighted and perhaps a cynical sales ploy by Tesla. There is a cultural difference between Ford selling EV crate motors, and Tesla jealously restricting parts sales, and bricking cars with "unauthorized" repairs.
I have a new M3 LR and, estimating from your reported results, 3% of the reported M3 LRs suffered battery failure. As others have said, the survey results are probably skewed towards people who suffered problems. I'm going to guess at a skew factor of about 30%, so that will drop the failure chance down to 2% on my car. Most of the time I trickle charge using a domestic 3-pin plug (UK), which probably reduces failure even more. I'm going to assume the risk is tiny and carry on enjoying the car!
Seems like selection bias. Where’d this survey come from? An open call for people with battery failure to vent their frustration?
Here's an example. twitter.com/seanmmitchell/status/1574076850518708224?s=20
What about failure by year? - it's interesting to see how the batteries degrade just over time, without necessarily having high mileage.
How many were LFP batteries?
Yes, which were LFP would be very interesting!
LPFs should have a much longer lifespan on paper at the expense of not working well in lower temperatures and being much larger and heavier for less power and less efficiency, so it would be interesting to see if the trade offs are warranted.
All teslas should have a 150k mile warranty standard , I’m gunna buy one regardless
My 2015 TESLAME Model S (S for SUCKER) p85d is an Electric Tin Can aka BUYERS BATTERY REMORSE!
Interesting but the sample size seems too small
1:30 you mean 67 faliures, "not 67% of those failures" you just made those charts extrmemly confusing to read by saying 67% percent.
So of those 7.5% what % had to be replaced out of warranty?
Since most failures were under 100,000 miles it was probably in the 3 percent range
Hello Sean,
For your stats, Nosecone P90DL here, failed pack at 98000 miles...
Interesting data for sure - and it does seem like a high failure rate. What happens when under warranty - do they replace it for free? I hear it is very costly to replace a pack - so an 8 year warranty does not seem very long.
Eight years is pretty good but more importantly for most is the mileage restriction. Many 4 year old Model 3's are already out of battery warranty due to mileage.
They give you a refurbished pack that already failed in another vehicle, then repair your one and give it to the next owner. It's good, but if the battery failed once, it seems logical it might fail again, it's not a "reset" back to 0.
I was surprised you did not speculate on the higher failure rate of Performance battery pack failures. What are your thoughts?
Personally I think it’s the thermal cycles of the high rate of draw on these performance models and the heavy foot of those that buy them (why spend the money if your not going to push it). I’m a mechanical engineer, not electrical so my guess is mostly speculation, but seems logical.
@@mylesgray3470 I agree with your hypothesis.
You can add this data point if you wish,
Tesla model 3 standard range 2021 37,000km
Battery failed, replaced by Tesla for 0$ on the 17 of November 2022.
Wow, that’s the lowest mileage failure I’ve ever heard of. How long did the replacement take? I have a Y long range which is only 3 months old. Hoping it lasts.
I bought a Model 3 used through tesla a few months back , no failure yet and we at like 97K miles
Great feedback! That’s awesome!
Would love for you to fill out the survey!
@@AllThingsEV - my only thing is that it has 97K miles , but I don't know anything about the previous owners battery , so it could have been swapped out , idk how to find this out and I called Tesla and they said they can't give me any previous records on the car. Which I think is kinda crazy because I would think Tesla would want the new customer to know what items have been previously repaired on the vehicle. Makes a big difference when buying a car with almost 100K miles if the battery was swapped at 90K miles then you have a brand new battery , ..... I don't know if the survey would have questions that would allow me to enter in something that would be accurate?
@@AllThingsEV - But I gotta say , for a 97K car , it drives like a brand new futuristic magnetic roller-coaster that is far better then any other vehicle new or used I have ever driven. Something about the way the steering Feels about the Tesla it feels so solid and connected and responsive. but other then that it really has so far been the best car ever. I drove a Kia Soul EV 2016 model for about 5 years , and never once did it ever need a repair or anything. So I have high hopes for the Tesla
@@RoschetzkyPhotography Tesla doesn't install new battery in warranty, they install refurbished batteries.
Sample size is really small.
Can you define "battery failure" - Are you saying complete failure or excessive degradation or ?
Replacement
Imo too much bias in this survey, not statistical relevant.. wouldn’t be surprised if real failure ratio was 10X lower. Ppl with issues are more prone to complain online
Your statement in itself has bias. What data has informed your statement? You've provided none. I've presented my findings. I'm happy to do another video with more survey entries. Send me Tesla owners.
The data could be skewed as owners by nature are more likely to answer survey if they’ve had a bad experience.
Maybe, but generally an EV is outside of the reach of your average driver, so I would bet it's more likely to be enthusiasts that believe this is the future and want to justify their investment, so they're more likely to share positive experiences, especially while under warranty. As these cars start coming out of warranty, I suspect this figure to get worse.
I wonder how hard driving affects the probability of failure?
Here's an incomplete list of what can contribute to a premature failure, a lot to think about with an EV:
1. Is the car in a heated garage
2. Is there car kept outside often, at what temperatures / humidity
3. Is it ever charged in cold temperatures
4. Is it discharged often below 20%
5. Is it charged often above 80%
6. Is it supercharged often, to what percentage?
7. how hard is it driven
8. Is it kept near the sea or ocean where air is humid and the salt contributes to corrosion
9. is it often driven in wet conditions where water ingress into the battery is more likely
10. what kind of battery is it, as LFPs have issues in colder temperatures (under +10c)
11. etc, etc, etc
If someone does not have a garage and lives in a wet, cold climate and is forced to supercharge, their battery will likely fail quicker than someone in ideal conditions that takes painstakingly good care of their battery. Think of a battery as a delicate fragile baby and every little thing can impact its health and longevity :)
I have never seen this percentage of battery failure before. When you say failure, do you mean Tesla needs to change the battery pack entirely? Where can we find this data? I have a performance model, so far so good & just did a complete battery check. Lastly, does this include Model Y 4680 batteries? The 2170 cells are like magic rocks!! ⚡️
Tesla unfortunately keep this data confidential so we have to rely on surveys. Tesla just show you % degradation and it's pretty rare for a pack to lose more than 20% range, it is far more likely to outright fail, which is not a stat Tesla publish (this seems like a pretty critical stat to know though!).
For how expensive the batteries are, I'd expect at least 500,000 km (300,000 miles) out of a battery.
There’s a video about a million mile Tesla and that’s about what he got. 325k miles on average per pack. 3 packs got him to 1 million miles and I believe his 3rd pack was still kicking. I believe the drive mortars lasted about the same so really, 300k is the expected life of the car before replacing things that don’t make sense to replace.
@@mylesgray3470 That does align with the better ICE vehicles. I've currently got about 350,000 km on mine (217k miles).
In summary, it seems that the 7.4% failures are composed almost exclusively of the much older Model S's with the older battery tech. There appears to be an extremely low failure rate for the relatively new Model Y and Model 3 vehicles and possibly the new Model S Plaids etc.
The summary shows most of the failures are Model 3 and Model Y though in the new data (which is halfway through the video).
@@DigiDriftZone Those numbers were for total percentages of vehicles surveyed NOT failures by model type. You can check again at 1:38
@@DigiDriftZone however as a disclaimer his data gathering and presenting method is not the clearest. So I’ll wait for a more comprehensive report which I’m sure will show up sooner than later
@@GT-22 the beginning of the video is previous data from years ago and halfway through it shows the new data, from which most failures are Model 3 and Model Y
@@GT-22 2:15 battery failure by model, not total surveyed. So most are Model 3s with the "new" battery tech.
So if you was buying a used Tesla what model would you buy?
Model 3 or Y
140 000 🤣 why not just lease it
Best data would come from Tesla themselves who are the ones who would have handled the warranty claim and/or the battery replacement. I only hear of a random failure every now and then, when someone posts it to Twitter or Facebook and blow it out of proportion and it is usually the same recycled story. I would bet the failure rate is much less than 1%. Tesla is on pace to manufacture 2M cars in 2022. A 6% failure rate is 120,000 cars or 329 cars per day. Even a 1% failure rate is 60 cars per day. If this was happening you would hear about it NONSTOP on social media and the local and national news.
We do hear it non stop if you pay attention, there is plenty of evidence for this but unfortunately Tesla refuse to share these numbers, that in itself should tell you something.
Even those high mileage teslas you see on RUclips, you look at the video description and most had 2 or even 3 battery replacements already under warranty and each battery usually is within the ranges this survey suggests. Unless the cars are kept in a heated garage, only left in optimal climate outside, used between 20-80%, very rarely super charged, they are not the "performance" range, you are not near the sea or ocean and you are fundamentally lucky not to get things like water ingress, then they do tend to fail after 5 to 8 years, even at low mileage.
Tesla could just release a 5-year failure rate chart for batteries or motors, but I suspect there is a good reason they don't.
Very poor data analysis.
As an example there is not any split between battery types as a percentage for that battery type. There are many more standard range cars than there are performance cars produced.
The survey is also self selecting and not a random sample. Self selecting surveys with small samples are very misleading.
Basically this video is FUD.
More than happy to review your analysis of battery longevity. Please link it up when you have a moment.
If you think Evs are going to save planet, ive got some ocean front property in Nebraska to sell you.
Tesla has all the data in their database. Using that data would make such a report much more informative and useful. If this survey represents the actual failure rate of the total, I wouldn’t buy a Tesla. Maybe that’s the point of the survey.
Tesla doesn't share that data, thus my video. Appreciate you watching!
@@AllThingsEV perhaps asking Elon directly since he’s usually fairly open and honest about the good and challenging aspects of tesla.
I don't trust Tesla/Tesla battery.
My brand new 2021 Model Y long range model had 330 miles at 100% charge. Battery pack went bad at 30,000 miles in first year. Tesla replaced it with 303 miles battery it is almost 9% degradation (10% degradation in 10years? Bolony!!). At 110,000 miles in third year battery went bad again. Tesla replaced it with 290 miles battery. It is over 12% degradation (another bolony).
I don't have warranty any more and I just hope this battery would last to 200,000 miles.
Most of times I use Tesla wall charger, so it is not from using supercharger either.
Just bad experience!!
Don't buy Tesla!!
so in other words ICE engines last llonger...
We call it a battery faller if it drops below 70% of new capacity let's say I bought a model 3 in 2018 and it has lots over that 70% but I drove it over 200,000mi it would probably still be a good car but only have around 200mi range witch is still better than some new cars on the market.
Tesla do not publish stats on battery and motor failure rates as it will probably scare the living daylight out of customers. It is very possible to have a battery at 200k miles with 13% degradation and it will show 87% capacity right up to the day it fails. Sure, there are Teslas with high mileage, but what percentage of those already had a battery replacement or what percentage didn't make it to this mileage? - that’s a stat you will not find from Tesla.
They do have all kinds of other stats in painstaking detail but something as simple as a 5 year failure rate? - nope - instead you have a chart of "degradation". Even if 99.9% of the cars were scrapped buy 0.1% of the cars were on the road with 15% degradation at 500k miles, the chart would still look identical. Degradation % is not a measure of remaining lifespan unfortunately.

Thanks?
Dotto too small a sample size also compared to ice cars I'd say its still.more reliable and likely more often covered under warranty. My Ford diesel motor destroyed itself just out of warranty but a similar tesla car battery would still be under warranty.... classic this video as FUD
You can get a second hand ford diesel engine for a couple thousand pounds, a similar battery would cost 10x as much.
For the sake of argument, imagine you have an 8 year old Tesla or an 8 year old Mercedes, both have failed, one with a dead engine, one with a dead battery. On the Tesla, you need to pay £23k just to repair it (plus an expensive recovery), on the Mercedes, you can repair it for a couple grand, or for £23k you can buy almost 3 replacement Mercedes cars of the same age and probably less mileage, 3 entire arguably more refined cars, for the price of a single battery. Let that sink in as Elon says :)
My Thoughts? DO NOT BUY! They need to remove Tesla name… its an embarrassment to Nikola Tesla! Rolling over his grave in shame with the way his name used in this crap electricity bull shiiite!
I agree. He wouldn't be too impressed with cars using batteries weighing the equivalent of 15 x 1 cwt bags of coal...and not getting any lighter with use !!
