Makes sense, this should be standard policy for all EV makers, MG wont't lose anything with A faulty battery pack, as most of it will be reusable for future battery packs or for stationary storage.

This is how you remove the anxiety, build your customer base and brand loyalty. how to boost new sales and of course 2nd hand sales.

When you're 60 years old, a lifetime warranty sounds long enough.

Autotrader recently had a Tesla with 430,000 miles. It was a private taxi. After independent tests the battery was still at 79%.

Wow. This is a great reassurance to MG owners if the extension to Lifetime warrantee or unlimited miles applies to existing MG vehicles. The whole EV market peaked last year in NZ with 27% share of new car market but has crashed to around 5% since January 1st when the NZ government agency NZTA, stopped the $NZ 7015 incentive payments. Any reduction in anxiety for potential EV buyers would be welcomed.

Hi Sam, Good to know about this! FYI, in Indonesia, the "lifetime warranty" battery benefit was started in late 2023 with the introduction of the Wuling Binguo EV (Bingo in China) for the 1st 1,000 buyers initially; the offer was then extended to more buyers & this "lifetime warranty" promotion was quickly followed by Neta & MG as well, with nearly identical terms & conditions as Wuling's. Some of the terms & conditions included a cap of 30,000 km driven annually, a requirement to service the car at authorized dealerships within the specified intervals diligently, a requirement to only use authorized spare parts & validity only to the original owner (lifetime warranty not transferable if car is sold), among a list of other terms & conditions (less than 10 I think at the time). I thought that the terms & conditions were quite reasonable for owners who plan to keep the car long-term for regular daily in-town commute. I agree with you that globally, MG will likely have different terms & conditions for the lifetime warranty as laws, regulations & market goals/pressures are different for each country. Cheers...

Lifetime warranty = game changer!

This is a fantastic move as batteries are proving to be long lasting and backing this up with long warranty will increase confidence of buyers.

From Scotland - just bought another MG - MG4 LR. Depreciation will go to nothing when the market realises the implications. Having owned Mercedes for years, I bought an MG on a special deal just for Scotland and saved £9k. After 4 years I gave the car to my son and bought the 4. Fabulous cars - far better than Mercedes, which cost a fortune in fuel and repairs.

Brilliant idea MG. Our 10 year old Tesla still going strong, battery and drivetrain. Several UK specialist companies have started up repiring Tesla packs for a fraction of replacement costs.

I have a phase 1 MG4 bought in 2023. The warranty is 7 years, not eight. If this is true about the lifetime warranty being retrospective to us relatively early adopters, then in one sense that's great. Warm fuzzy feelings all round. But on the other hand it doesn't change anything. I was expecting my battery (which is LPF) to outlast the car itself anyway.

Fantastic if true. Bravo MG! Thanks for the breaking news Sam!

This is a great news story thanks Sam 🙂, hopefully it will come to Australia soon, as an MG4 owner I gives me more confidence in the brand, occasionaly I cop some flak from naysayers that think that batteries only last 10 years, this is a good move by MG to quiet the EV critics

We bought our MG4 February this year... This would be great if the give the lifetime guarantee in Germany to im Future 😁

I'm a Tesla Model 3 LR owner and I put an average of 37,000 KM / year on it. My loan was originally 5YRS and I usually replace the car every 5YRS. At this rate, I'll be at 185,000 KM after 5YRS and be very close to the end of my battery warranty (8 YRS / 192,000 KM). I can only imagine the low-ball trade-in value Tesla would offer me for the car at that point. If Tesla would increase their battery warranty to 12 YRS / 500,000 KM, I think far more people would buy and would be less worried about keeping the car longer. It would also help their vehicles retain a higher value. I really hope he's right that maybe other manufactures will increase their battery warranty.

As far as I know, this warranty condition applies only to cars registered in the name of an individual (a person). If registered (or were registered) in the name of a company or organization (edit: I think leasing company is an exception if the buyer is actually buy with installments from it), or used for commercial purposes (such as a taxi, a car for hire, a car for rent) will NOT receive this warranty. In the case of registration change (owner change), it must only be change from one person to another person.

This is amazing. As you said, it takes away many people's arguments against EVs. I saw a clip recently where a Tesla Model S with 430,000 miles still had a battery capacity of over 70% which is incredible

Excellent move great for promoting EVs, hopefully it'll become standard across all EV manufacturers.

I'm now 10 years into my NCM battery and past the expected nr. of cycles. Still same range as when I got it, second-hand 3 years old.

been saying this for years, not just for EVs, all cars should have a complete lifetime warranty especially with how expensive cars are. this will also force manufacturers to make their cars reliable / durable and maybe prevent planned obsolescence.

I guess 2 things. 1. MG have done their sums knowing that an ICE engine bears a lot of warranty consideration, is no more. and are confident extended battery warranty is viable marketing pitch. 2. The electronics and software that manages the battery charge etc. is a next level of sophistication, ensuring longer battery life. I think it is a deal breaker for the next group of adopters now that the early adopters are by and largely satisfied. (Sydney Australia) :)

Actually this kind of warranty says to people the manufacturer believes the car will last a long time. That's what people want to hear.

Going to be interesting to see how this plays out. Reminds of Kia and Hyundia when they came to UK, sales took off when they offered 7 and 5 year warranties respectively.

This is my favorite channel. Despite the dip in crypto. I still thank you for the level headed financial advice I started crypto investment with $7,500 and since following you for few weeks now, l've got 25k In my portfolio. Thank you so much mrs Elizabeth Slone

In Australia the current MG4 battery warranty is 7 years unlimited km. For me that's around 140,000 km for my 64 kWh NMC battery. If they upgrade to lifetime that should increase the resale value but at 73 my lifetime may only be 10 years or less so it doesn't bother me much. What it does demonstrate is SAIC's confidence in its relationship with battery manufacturer CATL. CATL have recently announced 1 to 1.5 million km warranties on truck & bus batteries in China so extending this to SAICs MG brand of passenger vehicles is a bold move I think designed to cement and even extend their position as the worlds largest and best battery manufacturer. Bring it on. Other brands will follow suit fairly rapidly if they want to maintain market share.

As a MG4 owner I’m stoked at this news! Will help to firm up resale price on my car.

Here in Denmark, there are EV taxi that have rounded 1 mil km and they still are working.

The biggest impact will be on the 2nd hand market. Currently, people are nervous about 2nd hand EVs because they're not sure how long the battery will last. If the warranty stays with the vehicle then that problem is eliminated

We will need to read the fine print, but if this is true, this will be a game changer, especially if battery and drive components are unlimited mileage. Uber drivers will surely want one of these. If this is true then there is no manufacturer on the planet, EV or ICE, that can beat this warranty. Such a warranty will accelerate the shift to EVs and calm the nerves of those who have doubts about them. Revolutionary is putting it mildly!

This should become the standard on new EVs as all battery tech keeps improving. My 2023 Genesis Electrified G80 and 2024 Kia EV9 GT already came with a 10-year/100,000 mile powertrain and battery warranty which is much longer than I expect to keep the vehicles. 10-years has now become the minimum warranty I would accept on any new EV. If tech keeps improving on EVs as we have been seeing, improving warranties will help to increase EV adoption. Who would consider a ICE vehicle with 3 - 5 year warranty when EVs offer 10+ years?

Since early 2024 Most electric car brand already give life time warranty for 3 core component (battery, motor and controller) here in indonesia.

I'd say they will have revised this this policy long before 10 years is up and those that have bought with lifetime battery warranty will have it grandfathered in. This will likely only last until there is a critical mass of EV share of market then things will normalize. Bit like the days when there were concerns with burn in on Plasma and OLED TVs manufacturers would have 5 year and 3 year warranties. Most these days have 1 year for OLED since people have generally accepted that they will last if not abused.

Pretty happy with my MG4 LR/Trophy... it's not perfect (lacking some creature comforts) but rides well and lane keeping is actually not as bad as I feared it would be. On the topic of lifetime battery warranty, what it will do is massively up the resale value. We know eV resale value so far was pretty crap, well with that kind of warranty it will really improve

I'm intrigued by this and the potential integration with home solar. For example, I have an off-grid system with 9k panels and a 4x4kwh (16kWh) BYD battery. Living in NZ I don't always have enough sunlight over winter so an auto-start generator is used to charge the batteries when needed. I also have an MG4 charged from home when excess power is available, or in town when excess isn't available. If the batteries have a lifetime warranty then filling up in town and then using the V2L to charge the batteries would be around 1/2 the price of running a petrol generator and have no mechanical downside costs. Thoughts?

Wow 😮 this is incredible 👏

the main constraint in ICE Vehicles being still sold is the charging infrastructure. Otherwise now even in UAE the EVs (Chinese Versions) are cheaper than equivalent ICE versions. Once you get used to an EV very difficult to go to ICE vehicles

Bloody brilliant

If this could become the norm in the EV market, there goes ICE in America as battery lifespan is a major worry for many potential consumers...

A warranty is only as good as your ability to claim on it. If they fight and deny claims based on excessive wear and tear, then it's useless.

We had a lifetime warranty with our vauxhall 1st owner only and 100k miles but it worked gave us confidence in the brand, had it for 11 years and 95k though we were spending a fair bit of time getting it fixed it kept us going to main dealer for servicing and consumabkes like clutch brake discs etc. The early adopters of this kind of warranty will increase sales and market share and at least justify the high capital expense that comes with EV ownership. Cars considering their cost should have a 7 year warranty minimum i can get 5 years on a £400 washing machine.

For now it's only for Thailand , they will likely expand to other countries. In my opinion a lifetime is what they would deem fair and reasonable for a motor vehicle, typically 10 years. In my opinion the best way to deal with this battery issue is to bring down cost of replacement or repair, organize and train as many authorized battery replacement/repair centers as they can and freely supply factory diagnostic software to help with diagnostics. Unless this is done people will balk at buying a an older EV say over 8 years old, they will be scrap value just like an old laptop or phone.

The 2024 MG3 Hybrid, sold in Australia, includes a 7 year hybrid battery warranty, in addition to its 7 year unlimited warranty on the engine, systems, etc including 7 year body perforation warranty.

Is it not ironic, or has anybody noticed the Chinese could do with a British brand which they never could in a thousand years? What was the reliability of your typical MG product in the day? Guaranteed for three blocks past the dealer? In Vancouver the MGB was a popular car. They were notorious for dying on a rainy day due to the electrical system. Also ironic coming from a wet climate itself. Anyway, we are in a whole new paradigm here. What is the going to do the the auto industry when one can count on an auto purchase for life? That may be an extreme case but plausible.

Yes, I think this will make a difference to EV sales and yes, I think this will pressure other EV manufacturers to improve their battery warranties. A win for EV buyers and a win for the planet.

Actually this is quite widespread in 2nd or 3rd Tier Auto Makers in China. The offer lifetime warranty for the first owner.

This is a game changer move, would generate lot of confidence in prospective customers.

We have an MG4 Essence the battery warranty is good at 8 years but having a guarantee for longer would be nice. I am pretty sure the battery will last as long as we have the car. We tend to trade in our cars at the 10 year mark anyway. With the rate of change and improvements in EV cars it is fairly certain we will want a new car in 10 years anyway.

Many questions, including how much range degradation is the warranty good for - yet, this could be possible and the right move to radically increase the customer interest in an EV by temoving any diubt about batterry life (within some reasonable limits on use)?

Makes total sense, as EVs are consumer electronics, meaning future replacements of defective batteries will be far cheaper than now. Even without a lifetime warranty, the anti-ev warnings that "you'll have to replace your battery" scare no one who understands that in 10yrs you'l get a new battery that's 5x as good for 1/5 the price they are now.

I just checked the MG Australia website - in Australia it's still a 7 year/unlimited mileage warranty.

This will change the standard for the whole industry!

If this battery warranty covers used buyers it's a game changer as the other main reason people are worried about buying an EV is resale values. Fix resale values and the cost if ownership dropes dramatically.

I remember when Hyundai gave a lifetime warranty on the first Hyundai Sonata Hybrid batteries..

Define Lifetime.

Game changer, I'm not a huge fan of SAIC.....BUT this would definitely make me reconsider their cars, hopefully Geely and BYD do the same.

Sounds like a really good PR move. Maybe a few well maintained taxis will do long mileage, but I doubt this will cause a lot of high mileage batteries to be replaced. It should quiet the people who are afraid they will outlive their battery. It should definitely help resale value. Will it be transferable?

MG website warranty statement is relatively clear... only 7 years / 150,000km - whatever comes first... at least that is what I saw.

Batteries are getting cheaper and cheaper. Let's say that the battery pack needs replacement after 8 years..... in eight years a comparable battery pack will probably be under $1,000 to replace. That's how fast costs are coming down.

For most people, the standard 7-8 year warranty will be fine. It's just when these cars get to that age, the value will largely depend on the effective capacity remaining through a diagnostic process. A welcome addition to the car industry, but they need to tackle the range issues first.

Every other EV in China gives a lifetime warranty promo. Also in Indonesia and many others since the beginning of the year. One caveat you can't sell the car, warrants only the first owner and there's a yearly limit mostly around 30k km a year, and it can be used as a taxi. They have to because the competition is getting fierce.

Only the lifetime for the brand/service network. My mother had a sowing machine with a lifetime warranty from the 1960’s but the company is now gone. What we need is some form of Australian national guarantee scheme where you can pay reasonable amount to maintain it. Model for this is house construction insurance which protects from a builder going bust when you come back for fixes on the 10 year warranty.

Private use only. Not for commercial usage like Grab.

This will likely reduce Vinfast sales. Hyundai and Kia used longer powertrain warranty to reduce quality concerns. While it did cost them money on having to replace some faulty engine designs, it absolutely gained sales, market share while forcing some competitors to improve their own warranties. Peace

The irony is ICE engines often fail too and may be premature and hence dealership sells these extended warranties, and if there is lifetime warranty for batteries (and motor which supposedly last forever till the other car parts break) then this would surely beat ICE

As most EV’s (in the UK at least) are purchased on typically a 3 year finance deal, when the customer will the trade it in and refinance their next car for 3 years, I don’t think a ‘lifetime’ (whatever that means) warranty on the battery will make much difference to those buying new cars. However, where it might help is in the secondhand car market, where folk will have more confidence on buying a 3 year or older car if they don’t have to worry about the cost of a potential replacement battery. This in turn should help residual values, which in turn should help new car purchasers because their residuals at trade in should be better & therefore their monthly payments should end up being less.

Amazing warranty . In thailand the 12V lead battery warranty is only 1 year

We own an MG Cyberster here in China (Shanghai) the car comes with lifetime battery and driveline however max 30k km per year better than our Tesla model Y

I have a Tesla model 3 and this will definitely be a factor for me on my next car…

It will be interesting to see the details. I think this is headline grabbing. Overkill I think. As an MG4 owner Id be happy (And think reasonable) a ten year warranty with 200,000k miles 80% capacity. Anything more than that is amazing.

It would be best to read the fineprint. The lifetime warranty may only be applicable in case of a faulty pack and not battery degradatation below a certain percentage.

When I bought my MG4 with LFP battery I read that it could by charged at least 3000 times. Lets say 200 km for every charge, that's 600.000 km. I drive 10.000 a year. That's 60 years to use the battery. I was 53 when I bought the car. So the battery will last longer than I live. But the car itself, especially the bodywork? That's the big question.

I wonder if its transferable so secondhand would also be a good buy!

I have always thought that battery warranties after the initial, usually 8 year or so, was absolutely essential. Most batteries will last, but you don't want to be the unlucky owner whose battery has to be replaced 8 years and a week from purchase ! Now that MG is making it a reality, I must bring up a caveat: You need a company to be around to honour their warranty. I once renewed a service contract, a big one covering oven, fridge, freezer and dishwasher. I thought I was smart and took the longest renewal they offered, because the annual rate for that term was attractively cheap. The company was SEARS and they went bankrupt a month after I renewed 😏 How many years would you be able to depend on a Fiskar warranty?

MG requires to improve the quality of the plastics in the MG4. The exterior plastic have a tendency to crack from the inside, and the inside plastics scratch very easily. Otherwise the MG4 is fun to drive and handles very well.

This changes everything. Well not everything but it is a game changer. MG doing this shows how much confidence they have in their product, fair play to them. The EV haters will be crying in their tea when they hear this

I am guessing that this warranty is for the original purchaser (as with lifetime 12v batteries) IDK if this will alleviate fears in the used car market (because warranty does not transfer) but it goes a really long way to assuring that your car will not die before 200k miles/300km (when I sell my new cars :D )

in Australia a lifetime warranty is 25 years as a standard, cars are often on the road for at least 20 years. Hopefully this will come here as it will make a massive difference. I want to buy an EV but resale value is a major concern. if the battery is out of warranty resale will dip dramatically. This will fix that problem.

Interesting move as MG are bottom for approving warranty claims and when they have usually require a customer contribution unlike other manufacturers who either approve or don’t.

Yes I would buy an EV with unlimited Km battery warranty compared to those with limited warranty.

A good move (gimmick?), which may be a good way of increasing EV sales. However, although it takes away the worry of battery degradation, it doesn't solve all the problems people are having over charging times, range anxiety, charging infrastructure and insurance companies writing off vehicles for fear of battery problems after a vehicle is involved in an accident.

The battery pack of EV's is estimated to be 40 - 50% of the build price. If companies like MG show the courage of their convictions in reliability and longevity of their vehicles it would create a huge amount of confidence in yet to be converted IC drivers. If companies can replace and or repair batteries under warranty then it is a huge benefit to both customers and manufacturers. It would have a great impact on the trade-in/ resale market of EV's and accelerate the uptake of these vehicles.

Depends what "Lifetime Warranty" means. It must have limit / requirements. Because all lithium based batteries degrade over time - so if a battery is 50% capacity in 20 years is that a fail or a pass? What about down to 50% capacity in 1 year (but otherwise works fine)?

Wuling in Indonesia do this to for binguo The warranty will not valid if you sell the car. This is for first hand only

Unlimited km and it has V2L, looks like a game changer. What is servicing like for the MG4?

That sounds good I would buy an MG as a town car and keep my GLE Merc 450d which can do 1000 k/m on one tank to BNE from SYD

Hyundai offered a lifetime🔋 warranty in the USA for select models, a few years ago. I don't think they do anymore.

Remember when Hyundai and Kia did this with gas cars? It worked, and they grew like crazy just after that. I think it would work for EVs also. We have the data that a 70% range warranty has very little risk and the upside will be very good for the first automakers willing to do it. Not only that but by the time the cars need a new battery the replacement part will be a fraction of todays cost. They could also use warranty claims as an opportunity to sell the customer a new car or offer them an upgrade on the pack for a reasonable price.

I didn't think the issue is the length of the warranty but more the replacement cost of the battery pack. No one buys an ICE car expecting that the motor will last 50 years, but they don't expect to pay the same cost as a new car for a replacement motor. And that's the current issue with batteries, the current replacement cost is too high.

Fantastic news and will push others to offer the same. The haters are having less and less to hate about...

Sam we need more clarification. What you haven’t really addressed is the level of degradation of the battery. For example what if the battery performance after 5 years has reduced to 50%. That’s no good. Would like to know whether that warranty is for the battery degradation is no greater than 10%. Can you clarify that after 29 years the battery will be performing at 100% of its original state or 1%

I hope you're right and Tesla follows MG in extending battery warranties.

Toyota offered a million kilometers on the Proace batteries while ago

I bet the fine print on that warranty is about 50 pages long.

I think this could be one way to overcome the fossil fuel promoted FUD on batteries.

It's probably the "lifetime the original owner has the vehicle ". As most people ( companies ) change cars around 4-5 years thats when the warranty will end for 75% of cars .

sounds like the lifetime transmission oil. and when asked what is meant by the life time they say its life time of the vehicle which is about 100km.

This means Game over for Tesla

Accounting. Being that this is a high cost component of the car - accounting regulations (or lack there of) could give a massive advantage to cars produced in China. Kinda assuming that packs damaged in an accident would not be covered - this is an insurance issue. If an MG pack burns down your house with the car, don’t think MG will cover pack replacement either. This does seem to be a good PR move as you indicated.

The chance of battery failing completely is so rare that a lifetime replacement cost really won’t cost makers a lot and in return they attract skeptical customers to buy more EVs, a win-win situation

That would def convert me. Teslas battery warranty would only last me 4 years if I was to buy new with how much I drive a year.
