The main problem is you're down to 91% of original usable capacity after only 1,000 days.
- sp332 3y agoTesla's warranty is for 70% capacity after 8 years. So don't plan on having more than that left.
- toomuchtodo 3y agoYou get a better Model Y today for $50k than the Model S I bought in 2018 for $90k. These batteries will outlast the chassis. There is no material battery waste stream for recycling because the batteries last so much longer than expected. Auto consumers will ride the battery and EV learning curve where the price continues to decline and the power train improves over time. (Have supercharged my model s almost exclusively over 5 years and 110k miles and still only have 8% degradation, 100kw pack, n=1)

- toomuchtodo 3y agoMeh, they’ll figure it out like they always do. Engineering and manufacturing is hard. They’ve got $20B cash equivalents on hand and an $800B market cap, with a 2M unit/year run rate. I bought my S when I was concerned about their ongoing viability, but no longer concerned. The brand has strong enough legs, they’ll survive almost anything now. I’ve been hearing the rumors of Tesla’s death since the first roadster.
- culi 3y agoNobody's talking about Tesla's death (they're the most heavily subsidized US company today outside of military contractors/weapons manufacturers). But Tesla specifically has consistently ranked as one the least reliable brands of any automobile manufacturers. Even if you only look at EV manufacturers https://www.teslarati.com/tesla-placed-bottom-consumer-reports-reliability-rankings/ https://www.teslarati.com/tesla-placed-bottom-consumer-repor...
- toomuchtodo 3y agoDoesn’t matter what they’re ranked, they sell every car built at margins higher than any competing automaker. All that matters is the balance sheet, opinions can be ignored unless materially impacting volume. “This one weird trick.”
- Jka9rhnDJos 3y agoYes, because > They're the most heavily subsidized US company today outside of military contractors/weapons manufacturers Without the American taxpayer doing more than their fair share to keep them solvent, they’d be selling at 30-40% more. And they’re not selling. It’s why Musk started offering 84-month financing; to try and convince people to come buy them.
- toomuchtodo 3y agoGlobal auto market is 80 million units a year. Tesla will be able to sell into a market somewhere, even if a market softens. They also sell $20B-$25B/year of stationary storage, and are sold out for the next 2 years. Subsides are good if you believe in climate change. The top 40% (by income) of Americans pay federal income tax, they can afford to provide EV subsides. If you don’t believe in climate change, there is no value in a conversation.
- blake1 3y agoThere’s no reason to think that’s a permanent state of affairs though. Stellantis claims to have better margins than Tesla. Tesla sells a large portion of vehicles in China where the margins are tiny compared to those in the US market. https://www.reuters.com/business/autos-transportation/stellantis-operating-profit-rises-11-h1-topping-forecasts-2023-07-26/#:~:text=He%20argued%20that%20the%20Stellantis,the%20group's%20most%20profitable%20region https://www.reuters.com/business/autos-transportation/stella....
- xenadu02 3y agoFWIW this person has been driving that car for 5 months now without any issues. Supposedly Tesla's engineering department looked at the details and said the cracks are not a problem. I'm not a licensed engineer that specializes in chassis design nor metallurgy so I can't assess that claim. Tesla's customer service org still needs improvement. If I were the service manager and assuming engineering really signed off on the structure being OK as-is... I'd just have one of our welders patch up the cracks. Even if it doesn't affect the structure it would give the customer peace of mind. If you think these kinds of issues are unique to Tesla prepare to be surprised. Traditional dealers deal with this crap on half the new cars they receive. When I bought an Infiniti a few years ago it came with a couple of flaws from the factory (lest you think the Japanese manufacturers are better) - the dealer issued me a "we owe" sheet with a promise to repair the issues which they did once parts arrived. The lauded BMW sold me an M3 with defective journal bearings that grenaded the engine at 20k miles. At least a missing brake reservoir cap can be easily replaced! The replacement block alone was billed to BMW at $14k excluding other parts and labor. That same M3 ate its differential bearings not long after. The service tech's explanation to me was that "Hans must have come into work hung over that day". My point is: if you go looking for problems you will find them. With every make and model. You can't point to one person's possible problem and say "ah-ha! That car maker produces garbage!"
- npunt 3y ago> lest you think the Japanese manufacturers are better They are
- xenadu02 3y agoThat has not matched my personal experience so I'm going to say you are wrong. In the end both of us are just posting personal experiences and opinions here, not data.
- npunt 3y agoApologies for prior terse response, I wasn't talking about a personal experience, just the almost-goes-without-saying truism that japanese brands are the most reliable and have dominated pretty much every car reliability rating since the 70s. You used a single anecdote to make a very broad claim so the burden of proof is on you to back that claim up. The data is really easy to find. Here's two examples of CR results: 2011: https://www.nydailynews.com/autos/japanese-cars-reliable-survey-article-1.968094 https://www.nydailynews.com/autos/japanese-cars-reliable-sur... 2021: https://www.thedetroitbureau.com/2021/11/japanese-makers-dominate-new-consumer-reports-reliability-study-but-domestics-deliver-surprises/ https://www.thedetroitbureau.com/2021/11/japanese-makers-dom...
- culi 3y agoWoof. An EV battery produces between 2.5 and 16 metric tons of CO2. About 9% of emissions for a combustion engine vehicle is in the initial manufacturing alone (compared to ~35% for an EV). An EV's battery is by far the most polluting in the process and manufacturing of the battery alone produces more emissions than the entire manufacturing process of an average combustible engine vehicle. If people are replacing their batteries every 8 years, we _REALLY_ need to optimize our grid and figure out a real solution to recycling EV batteries ASAP
- tw04 3y ago>If people are replacing their batteries every 8 years, we _REALLY_ need to optimize our grid and figure out a real solution to recycling EV batteries ASAP We already have both figured out and have for quite some time, at this point it's just a combination of scaling up (for recycling), and political will for rapid expansion of renewables and bringing new nuclear plants online. https://techcrunch.com/2023/08/29/redwood-materials-raises-1b-to-expand-us-battery-supply-chain/ https://techcrunch.com/2023/08/29/redwood-materials-raises-1...
- XorNot 3y agoRecycling EV batteries would continue to produce CO2 (by the shady metrics people use to attach CO2 production to a process which does not include any emissions directly from the manufacturing process, unlike say, concrete production).
- xenadu02 3y agoBut people aren't replacing their batteries every 8 years. Modern solar panels are usually rated to 90%+ production at 20 years. Mine are rated for 92%. It turns out all the sturm und drang about having to replace solar panels and "oh-my-god manufacturing emissions will outstrip the benefits produced over their lifetime" ... was bunk. Rounded down: no one ever replaces their solar panels. In all likelyhood even 100 year old panels will still be producing >50% of their rated output. For the rare case where someone replaces panels the old panels are re-sold to a new user... they are very rarely junked. Batteries don't last quite as long but they have similar characteristics. People forget about range anxiety and just drive the vehicle. It turns out most people don't see capacity reductions anywhere near the dire predictions. They often don't notice the capacity reduction nor care even when they do notice. Even when someone wrecks an EV the batteries are often not recycled - people buy and use them either as replacements for their own vehicles or for power backup systems. Fleet stats are in the early stages but so far even after driving for 10+ years most Tesla owners are on the original battery and happy with it.
- HPsquared 3y agoIt does seem to level off eventually though, not a linear decline at that rate.
- MostlyStable 3y agoWhy? Obviously less degradation is better, but I have done a couple Northern Oregon to Central California trips in an EV. The total charge time for the trip was ~2 hours (on top of ~10 hours of driving), and I have a relatively low end, slower charging vehicle (<100 kW). If I lose 10% of my range, I'll add about about 15 minutes of charging time to the trip. That's doesn't really seem like that big a deal. And slightly higher end cars (and likely all cars sold a few years from now), will have even less.
- culi 3y agoI think OP meant your permanent range. Like your batteries capacity degrades substantially higher if you use fast charging
- mikercampbell 3y agoYeah, I don’t know EV’s or how often it’s intended you replace your battery, but I would feel that 9% just because I hyper focus haha
- MostlyStable 3y agoYes, but decreased range only matters on long trips (like the one I describe), and the only thing it does it make you have to charge more frequently. I described how much that would actually matter on a real trip. As for your second sentence, the entire point of this article was that that's not true.
- culi 3y ago> As for your second sentence, the entire point of this article was that that's not true. 1. It was not my claim, I was just clarifying OP's claim. 2. "That's not true" is an oversimplification. The article is basically saying that the software vehicles have to prevent damage from fast charging generally seems to work and minimal damage is occurred. But it still cautions against fast charging in high temperatures for example
- ballenf 3y ago
- dclowd9901 3y agoFor comparison’s sake, you could expect a similar degradation power wise on a ICE… over 30 years. This is my biggest hang up on EVs. They age like paper straws.
- ClumsyPilot 3y ago> degradation power wise on a ICE… over 30 years Yeah, for a Toyota that's owned by an expert car mechanic, who's hobby is doing full engine rebuilds every Tuesday. Our BMW was a write-off after 12 years.
- AngryData 3y agoThat sounds more like a BMW problem unless you were putting huge mileage on it. Lots of 90s vehicles on conventional oil would go over 300,000 miles without replacing any major parts. Just alternators, plugs, and $10 sensors. Anything newer running on full synthetic is a total piece of shit if it isn't hitting 400-500,000 miles
- jgalentine007 3y agoI think the BMW is more of the issue than anything else…
- kristopolous 3y agoaverage ice car life-cycle is 12 years. EV lifespan is comparable. It's a weird attack angle for the anti-EV rhetoric. People talk about the longevity of an EV and somehow either don't realize or acknowledge its comparable to an ICE vehicle and then put this worried look on their face.
- somerandomqaguy 3y ago.....? The average age of cars are hitting 12 years. https://hedgescompany.com/blog/2022/02/how-old-are-cars/ https://hedgescompany.com/blog/2022/02/how-old-are-cars/ If the data here is to be believed, then cars 2009 and prior make up 44% of of all cars on the road today, or or very roughly around 127 million cars. There really isn't that much to be said about EV longevity because to be frank, they isn't really enough data right now. There's not enough that are not old enough.
- linsomniac 3y agoFYI: The Tesla warranty on the battery and drive unit is 8 years and 100K/120K/150K miles (depending on model) that it retains 70% or better capacity.
- kbos87 3y agoPractically that isn't a problem for the majority of people though. Yes, you lose 9% of range after 1,000 days. Go into the purchase expecting that, the same way you'd expect that you aren't going to get the EPA rated gas mileage you see on the sticker in the window. In a model Y with 340 miles of rated range, you'd be down to ~310 miles of range. And what happens from there? This study shows the same effect that others do - range loss pretty much levels off at a certain point. 300 miles of range is more than sufficient for 90% of people, especially when they can wake up with a fully charged vehicle every morning if they are charging at home.
