Tesla Model 3

For up to 100,000 miles on the standard battery and up to 120,000 miles on the long-range battery.

The battery retention portion of the warranty differs from that of the Model S and X. Neither of those Tesla carry a retention guarantee, nor does Tesla list degradation from battery usage as part of the Model S & X warranty. However, long-term tests have proven that most Tesla suffer only very little degradation over time, far below the 70% threshold put forth by Tesla for the Model 3.

Here’s the wording from Tesla in regards to the Model 3 battery warranty and retention guarantee:

Battery and Drive Unit Limited Warranty

Your vehicle’s Battery and Drive Unit are covered under this Battery and Drive Unit Limited Warranty for a period of:

•Vehicles with Standard Range Battery – 8 years or 100,000 miles (160,000 km), whichever comes first, with minimum 70% retention of Battery capacity over the warranty period.

•Vehicles with Long Range Battery – 8 years or 120,000 miles (192,000 km), whichever comes first,with minimum 70% retention of Battery capacity over the warranty period.

This 8-year time frame lines up exactly with the Model S and X, though neither of those vehicles have a listed mileage limit.

As for the more basic new vehicle warranty, the Model 3, like the S and X, gets 4-year, 50,000-mile coverage:

Basic Vehicle Limited Warranty

Subject to separate coverage for certain parts and the exclusions and limitations described in this New Vehicle Limited Warranty, the Basic Vehicle Limited Warranty covers the repair or replacement necessary to correct defects in the materials or workmanship of any parts manufactured or supplied by Tesla that occur under normal use for a period of 4 years or 50,000 miles (80,000 km), whichever comes first.

Here are the battery-related warranty details from Tesla’s Model 3 New Vehicle Limited Warranty document:

70% is a bit light, but reasonable. 80% would be nice, but I can see their point on not promising that level on the warranty. I wonder what a re-furb pack for a 3 will cost in 6 or 7 years if you are someone who drives a lot more that 15k a year. Though it could be that the calendar (or how and where you park the car during the day) has a larger affect on the pack life than the cycles.

70% is the typical capacity at which a PEV battery is considered end of life. Essentially they’re providing a minimal life guarantee.

Brandon

Yes, and the fact is, good batteries like Tesla uses will only degrade at around 1% a year.

For standard range of 220 miles 70% is about 150 miles, which is more than many low end EV’s such as BMW i3, Nissan Leaf, VW eGolf …

We did get 80% warranty on our Tesla batteries and 4 years.
But now after 4 years still 96% left !

I saw a chart of fleet battery life over a 4 year time frame for Model S owners and it looked like many took a noticeable hit of 2-4% the first year and then range loss really tapered off to a little over 1% per year. Here is hoping that the range loss for the 3 is as good or better! Because if the chart is any indication of what will happen in the next 4 years, they could have warranteed the S to 80% with very few people having range loss of 20% or more.
I wish I had saved a link to the site.

70% after 8 years is pretty decent. It means that you will have another 4-5 years of usable range of the car after the eight year.

P.S. It is not realistic to expect EVs to be usable for 20-25 years as you can do with some ICE cars. EVs will have different usage patterns than ICE cars, and this might even be a good thing. There will be much less outdated cars on the roads and car companies will be motivated to recycle old cars and batteries (and will even pay owners for their old batteries)

Can you elaborate? I think it’s very likely for long range EVs to stay on the road for 2 decades or more. Not only will 50% range still be useful for most, but by 2030 replacement battery packs will be very cheap, and maintenance/running costs (which dominate old car costs per mile) will be far lower for EVs.

Back when I was a student, I would’ve loved to own a 10-year old EV instead of a gas car.

The drivetrain is a relatively small cost % of an entire ICE car. You can get warranteed, reconditioned engines for the common economy/midsize cars for a couple of $K, and new ones for not much more.
A 20-y.o. car, ICE or BEV, has lots of other systems that will need replacement or refurbishment: Suspension, steering, brakes, safety systens, bodywork, cooling, HVAC, 12V electrics…

But he said “as you can do with some ICE cars”. So what is it about those cars that would make them last longer than an EV equivalent? He’s clearly not talking about suspension, HVAC, etc.

A 25 year old car will typically have had some kind of major repair…motor rebuild, transmission rebuild…businesses have been created to address that need.

What makes you think that businesses won’t respond to the need to rebuild battery packs?

Instead of grease monkeys, you’ll need solder monkeys =)

They may sell old packs to grid applications but they will not be rebuilt. People may think a 50 kWh pack will be SO cheap in 5 years, question assumptions.

SJC, GM will already sell you a re-furb battery pack for the Volt if yours is fried or not working right. I imagine other companies will do the same, at least for the next 5 or 6 years. Further out, who knows.

Refub makes no sense, most of your cells are old but some are new, not really reliable.

Very good point. A proper refurb would have to include cleaning/reconditioning all electrical connections, circuit boards, coolant pump and replacing all cells with new cells. In other words, close to the cost of a new pack.

Refurb packs appear to cost less than half what a new pack costs if you trade in your old pack. GM refurbs cost 1/3 the cost of a new pack.
They probably last a good bit more than half as much as long as a new pack. They do come with a warranty.

They have been refurbing Prius battery packs for years. It works great. There is no reason why Model 3’s also wouldn’t get refurbed when the time comes.

Most people are not worried about Tesla battery. It’s the other stuff like drivetrain, screen, glass roof, door handle, etc….

For the 10x larger market share that the Model 3 is targeting, I think many potential owners will have worries about battery life.

They should want to know what a new pack costs NOW, then they can dream of price reductions.

Well, people tend to worry a lot about the stuff that affects them the least. Terrorism is a huge worry according to polls even though smoking, alcohol and traffic are each several orders of magnitude higher threats.

70% is wayy too low. Should have been at least 80%.

@Prsnep
What are other manufactures warranty ? 80% or more after 8 years or 100k miles /

Prsnep

Your car’s range dropping by ~30% after 100k miles and not being covered by warranty doesn’t concern you?

Just like with GM and the Bolt’s 60% degradation warranty, Tesla’s 70% degradation warranty for the Model 3is likely covering the worst case scenarios. It’s likely very few owners will ever approach 70% degradation unless they punish it daily (100% charges, multiple fast charges a day, etc…).

Interesting to see if there is any language in the warranty pages that cover frequent Supercharger use.

“Interesting to see if there is any language in the warranty pages that cover frequent Supercharger use.”

Exactly.
I would bet there is a clause there to cover it.

Nix

How much you want to bet? How about $35K?

Did you bother reading the full warranty doc? There is absolutely no mention of superchargers. The limitations are typical you would find in any new car warranty, including stuff like the car being salvaged, acts of God, improper maintenance, etc.

bro1999
Guest

No, I didn’t read the full doc because I’m not a TSLA zealot like you.

Model S/X owners have had their Supercharging rates permanently throttled after excessive SC’ing, so it’ll be interesting to see if the same happens to 3 owners.

Nix
Guest
Nix

Actually, that is also inaccurate. Tesla owners who bought their cars when ALL superchargers operated at 90 kW have simply been limited to the original charging rate that existed when they first bought their cars.

I realize anti-Tesla folks like you would rather make up baseless nonsense instead of actually becoming educated on the facts when they are provided to you. But you look silly when your claims about the warranty are proven wrong by the actual warranty itself, and you STILL make up stuff trying to justify your posts.

Warranties are usually made with huge margins so that the manufacturer preferably never have to own up to it. So if Tesla says it will have at least 70% capacity left after 100k miles it will probably in the vast majority of cases have more than 80% capacity left.

I’d be shocked if it didn’t. I don’t baby my Leaf and I’m down about 16% after 140,000 km (~87.5k miles). I expect to be around 80% capacity at 100k miles.

WadeTyhon

Perfectly reasonable. But that is a worst case.

Like GM, Tesla batteries will far outperform this guarantee unless you try to actively thrwart it!

ModernMarvelFan

That is great. Peace of minds.

70% of 320 miles is 224 miles. Still great.
70% of 220 miles is 154 miles. Not too great.

60% of 238 miles is 142.8 miles. Not great at all.

So, I guess they are all designed to only catch the “exceptions”…

Mind you we are talking at 8 years when a car typically has 20% of its value.

If I could have a Model 3 with 150 miles for $10k, sign me up.

Of course this is a lower limit, so average will probably be 180 miles.

240 original, 230 typical full charge. 3 years, 50k miles. 4% loss. Expect I will be down to 220 at 100k miles with 92% retention. That loss is a minor inconvenience 2 times a year. I could get by down to 150 miles with today’s infrastructure and I expect that won’t happen in my lifetime (I am 47). The car will have other issues before that – like lack of FSD.

This is great news! Of course most of the buyers will never need the warranty because the battery pack outperforms that minimum standard. But the lack of any guarantees with respect to capacity loss until now was nonetheless an issue, since it’s a component of the car it would be very expensive to replace. Far better to let all customers cover the tiny average cost per car rather than everyone sitting with a small but real risk of having major problems.

I wonder if the other manufacturers will follow suit. Nissan sort of has a capacity guarantee, but it’s framed in terms of meaningless bars in the display that Nissan can even change after the sale (I doubt they would, but there’s no legal protection for the buyer if they did). The others, AFAIK, don’t have any kind of capacity guarantee, they just guard you against malfunctioning within a time and range limit (just like with Model S & X).

In EU that would be illegal.

You buy what you buy and if manufacturer purposefully decrease value after sale you are covered.

2y mandatory guarantee also cover item at sale moment. So manufacturer can not use newer specs to cover up.
