For a Chinese automaker opening its first showroom in Frankfurt, Sydney, or Birmingham, the warranty booklet serves as a form of advertising. It is the closest thing to a track record a badge with zero local history can offer. Buyers outside China have not spent a decade watching these cars age in their own driveways, so the paperwork has to do the convincing instead.
The trick is not new: Hyundai set an early benchmark with its five-year warranty coverage in 1999, and Kia followed with a seven-year term in 2014, a move that later pushed MG to revise its own cover. What has changed is the sheer number of Chinese car brands now racing to out-warranty each other, sometimes inside the same dealer group.
Worth knowing before the numbers: there is no such thing as a single, global Chinese-brand warranty. BYD Europe, BYD Australia, MG UK, and MG Australia each set their own terms based on local competition, and those terms often shift. What follows is the picture as it stands in mid-2026.
MG
MG remains the brand every rival is still chasing, and its own story is a lesson in how these headline numbers evolve. In the UK, it backs every new model with seven years or 80,000 miles of cover, plus a separate eight-year, 100,000-mile guarantee on the battery pack, which lasts as long as capacity does not fall below 70 percent of its original state.
For its models in Australia, MG went further still, launching a 10-year, 250,000-kilometre warranty in August 2024 that applied without requiring buyers to service exclusively through MG dealers, a genuine first for the market. That freedom did not last. Starting July 2025, MG Australia revised the terms so the full decade of cover now requires servicing through an authorised MG dealer, the same conditional structure long used by Mitsubishi and Nissan.
BYD
BYD makes up the more dependable middle tier, leaning on straightforward, largely unconditional terms rather than a single eye-catching number. BYD’s baseline across most markets is six years or 150,000 kilometres on the vehicle, an eight-year, 150,000-kilometre guarantee on the electric drive unit, and a 12-year, unlimited mileage warranty against rust perforation.
Its real headline is the Blade Battery cover, which BYD extended in January 2026 to eight years or 250,000 kilometres across the UK, the EEA and Switzerland, a substantial jump from the prior cap, applied retroactively to owners who already had the car. Australia runs on entirely separate terms: six years or 150,000 kilometres on the vehicle, and eight years or 160,000 kilometres on the battery and drive unit, which is meaningfully short of the European figure.
GWM and Omoda/Jaecoo
GWM’s Haval, Ora and Tank range has quietly offered seven years and unlimited kilometres on the vehicle in Australia since 2018, with hybrid and EV models adding an eight-year, unlimited-kilometre warranty on the battery pack.
Chery’s newer Omoda and Jaecoo nameplates go a step further again, offering an eight-year, unlimited-kilometre warranty in Australia, a full year longer than the standard Chery badge gets, while UK buyers get seven years or 100,000 miles on the vehicle, an eight-year high-voltage battery warranty, and a 12-year body perforation guarantee.
Zeekr
Zeekr shows the same conditional pattern MG did. Geely’s premium EV arm advertises a 10-year, 200,000-kilometre warranty pitched directly against Toyota’s own maintenance-linked cover, but read the fine print, and it is a five-plus-five structure: buyers start with five years or 100,000 kilometres as standard, reaching the full decade only if every service is done within Zeekr’s own network.
The battery itself carries a flat eight-year, 200,000-kilometre guarantee regardless of who does the servicing. It is a strong offer from a brand that only opened Western European showrooms in late 2025, but the marketing headline and the unconditional figure are not quite the same thing.
XPeng
XPeng splits its terms by market sharply enough to catch buyers off guard: continental Europe gets seven years or 160,000 kilometres on the vehicle and eight years or 160,000 kilometres on the battery, while the UK, where XPeng only arrived through importer International Motors in 2025, gets a shorter five years or 75,000 miles on the vehicle, though the battery cover still holds at eight years or 100,000 miles.
Nio
Nio barely competes on the printed number at all: its European vehicle warranty runs five years or 150,000 kilometres, but under its Battery as a Service model buyers do not own the pack outright. They lease it instead, which lowers the purchase price and lets them swap a depleted battery for a charged one at Nio’s own stations rather than lean on a fixed degradation clause. It only works, of course, where Nio has actually built the infrastructure.
Leapmotor
Leapmotor offers the shortest vehicle term on this list, four years or 60,000 miles in the UK, alongside a separate eight-year, 100,000-mile battery guarantee, but the real product being sold is Stellantis, which owns 51 percent of the joint venture and has folded Leapmotor into its own dealer network across more than 40 markets.
A shorter warranty, backed by one of the world’s largest automotive groups, can be a safer bet than a longer one from a standalone Chinese newcomer with no Western footprint.
GAC Aion
The newest arrival makes the boldest claim yet. GAC Aion, only now building its UK network through distributor Jameel Motors, is rolling out what it calls the Great 8, a set of matching eight-year commitments covering the vehicle warranty capped at 100,000 miles, scheduled servicing, MOT cover once the car is old enough to need it, and roadside assistance through a tie-up with the AA.
In Thailand, it has gone further still, converting the battery, motor and control box cover on several models into a genuine lifetime warranty with no year or distance cap at all. Whether that scales to a market as dependent on dealer depth as the UK is the open question; promising eight years of everything is a large claim to live up to for a brand with one model on sale.
What we don’t know
Two names are conspicuously thin on export warranty detail, for opposite reasons. Xiaomi, despite topping direct-import sales charts on grey-market platforms in more than a dozen EU countries, has no official European dealer network and does not plan to open one until 2027, with Germany as its first stop. Every Xiaomi on a European road right now is running on an importer’s warranty rather than a factory-backed one.
Denza, BYD’s premium sub-brand, only opened European order books in April 2026 and inherits its parent’s general approach, though it has yet to publish fully independent terms model by model.
The warranty is only as good as the company behind it
None of these figures mean much if the issuer is not around to honour them. China’s domestic market has already served as a cautionary tale. WM Motor, once a popular budget EV maker, filed for bankruptcy in October 2023, and brands including Singulato and Aiways have since exited the market entirely.
More than 20 domestic EV makers have folded since 2020, leaving an estimated 160,000 owners dealing with the fallout, in some cases losing basic remote functions such as locking the car or checking its charge state once the manufacturer’s support went dark. Aiways is the sharper warning for buyers outside China specifically: it sold cars across the UK and Europe, and dealers that once carried the franchise have in several cases stopped supporting the brand entirely, leaving a warranty that exists on paper with nowhere left to redeem it.
The more useful question, then, is not just how many years a brand promises but how many dealers it has to make good on that promise. BYD’s UK network has grown to roughly 100 dealers by early 2026, up from around 60 at its 2022 launch, and that still trails what a mainstream Japanese or Korean brand offers several times over. A seven-year warranty from a manufacturer with a dozen service centres in a country is a different product to the same seven years from one with three hundred service centres.
Editor’s Take
Judged purely on the page, MG’s Australian deal and GAC Aion’s new UK package are the hardest figures to beat, and BYD, GWM and Omoda Jaecoo offer the most dependable unconditional middle ground.
But the brands that command the most trust may be the ones playing a longer game than the warranty document suggests: BYD for its sheer scale and vertical integration, Leapmotor for the simple fact that Stellantis, not a young Chinese startup, is ultimately on the hook. The best warranty, in the end, is the one a buyer can still cash in on five or eight years from now, not just the biggest number printed in the brochure.
