No. Kia and Hyundai are separate automakers, but they belong to the same Hyundai Motor Group corporate family. Hyundai Motor Company—the company behind the Hyundai vehicle brand—is Kia Corporation’s largest shareholder, with roughly 35% of Kia based on Kia’s latest publicly reported ownership information. Kia is not 100%-owned by Hyundai, and it is not simply a Hyundai division or trim level.
That relationship explains why Hyundai and Kia vehicles often share platforms, engines, electronics, software, suppliers, and sometimes manufacturing resources. It does not mean the vehicles, warranties, dealerships, recalls, or legal responsibilities are automatically interchangeable.
The short answer
Same company? No.
Same corporate family? Yes. Hyundai Motor Company and Kia Corporation are separate automobile companies within Hyundai Motor Group.
Does Hyundai own Kia? Hyundai Motor Company is Kia’s largest shareholder and owns roughly 35% of Kia—not 51% today and certainly not 100%.

They collaborate heavily, but Kia has its own corporate identity, management, financial reporting, vehicle lineup, brand strategy, dealer network, and warranty administration.
Understanding the names: Hyundai company, group, and brand
The word “Hyundai” causes much of the confusion because it can refer to several different things:
- Hyundai Motor Company: a separately listed automaker that develops and sells vehicles under the Hyundai brand.
- Hyundai Motor Group: the broader corporate group and affiliate network that includes Hyundai Motor Company, Kia, Genesis, Hyundai Mobis, Hyundai Transys, Hyundai Steel, Hyundai Glovis, and other companies.
- Hyundai Motor America: Hyundai’s U.S. operating organization.
- Hyundai brand: the consumer-facing name on Hyundai cars and SUVs.
So, “Hyundai owns Kia” is an incomplete shorthand. The relevant company is Hyundai Motor Company, while the broader relationship is through Hyundai Motor Group. The group should not be understood as one legal company that sells every vehicle under every Hyundai-related name.

Who owns Kia today?
Hyundai Motor Company is Kia’s largest shareholder. Kia’s latest public ownership information, reported at the end of 2025, lists Hyundai Motor Company with 137,318,251 Kia common shares.
Kia’s shareholder page displays two slightly different percentages in different tables: 34.53% in its shareholder-composition table and 35.17% in its related-party table. For that reason, the clearest wording is that Hyundai Motor Company owns about 35% of Kia.
This is a substantial holding and gives Hyundai Motor Company major strategic influence, but it is not a controlling 51% or a complete 100% ownership stake. The remainder is held through other investors, institutions, employees, treasury stock, and foreign shareholders, as reflected in Kia’s ownership disclosures.
For the current share count and the different reporting percentages, see Kia’s shareholder information.
Why do some sources still say Hyundai owns 51% of Kia?
Because 51% was the original stake associated with Hyundai’s acquisition of Kia in the late 1990s. It is a historical figure, not Kia’s current publicly reported Hyundai ownership percentage.
Older articles often repeat the original acquisition number without explaining that the ownership position later changed. The safe distinction is:
- Then: Hyundai acquired an approximately 51% stake in Kia and Asia Motors as part of the late-1990s transaction.
- Now: Hyundai Motor Company’s publicly reported Kia stake is roughly 35%.
- Not true: Hyundai Motor Company owns 100% of Kia.
Kia remains a separately listed corporation with its own shareholder information, financial results, board information, and investor-relations materials. Kia says it was listed on July 21, 1973. Hyundai Motor Company also publishes separate stock issuance and shareholder information.

Useful primary sources are Kia’s corporate information and Hyundai Motor Company’s stock information.
When did Hyundai acquire Kia?
Kia was established on December 11, 1944, while Hyundai Motor Company was incorporated in December 1967. The two companies were independent automakers before their corporate relationship developed during South Korea’s late-1990s economic crisis.
Kia entered court receivership during the crisis, and Hyundai Motor pursued its acquisition. Hyundai’s official history records the acquisition of Kia Motors in 1998. Hyundai’s historical financial reporting gives additional transaction details: the 51% acquisition of Kia and Asia Motors was carried out through a consortium, with payment made on March 29, 1999, under a stock-acquisition agreement dated December 1, 1998.
That is why both 1998 and 1999 appear in reputable descriptions:

- 1999: the payment and completion phase recorded in the historical financial filing.
Neither date necessarily contradicts the other. Hyundai’s official corporate history, its historical financial report, and Kia’s history of the acquisition provide the background.
What Hyundai and Kia share
Shared ownership influence has produced extensive technical and operational cooperation. That cooperation is real, but it is best understood as common engineering and group-scale manufacturing, not proof that every Kia is mechanically identical to a Hyundai.
1. Vehicle platforms
Hyundai and Kia frequently build different vehicles on related or shared architectures. A platform typically provides a foundation for elements such as the vehicle structure, suspension attachment points, electrical systems, powertrain packaging, and manufacturing processes. Designers and engineers can then create different bodies, interiors, dimensions, software, equipment levels, and driving characteristics around that foundation.
The clearest modern example is the Electric-Global Modular Platform, or E-GMP. Hyundai Motor Group developed E-GMP for electric vehicles across its Hyundai, Kia, and Genesis brands. Hyundai’s IONIQ models and Kia vehicles such as the EV6 and EV9 are examples of group electric vehicles using E-GMP-related architecture, although the exact battery, motor, software version, dimensions, equipment, and specifications depend on the model year and market.
See Hyundai’s explanations of E-GMP and the group’s broader modular vehicle strategy.
2. Engines, transmissions, batteries, and electronics
Related Hyundai and Kia models may use common or closely related:
- Gasoline and diesel engines
- Transmissions
- Hybrid-system components
- Electric motors and battery systems
- Electronic control modules
- Safety sensors and other vehicle electronics
- Suppliers and production processes
However, “shared engine” does not mean identical vehicle. Power output, emissions equipment, calibration, cooling, transmission programming, intake and exhaust components, mounting hardware, and software can differ. Even when a part number or engine family is related, the application must be checked against the specific vehicle.
Hyundai’s U.S. warranty handbook, for example, refers to components manufactured or installed by Hyundai Motor Group and Kia manufacturing facilities among components that may be covered on Hyundai vehicles. That demonstrates production overlap in some cases; it does not establish that every Hyundai and Kia vehicle uses the same parts or is assembled in the same facility.

3. Software and infotainment development
Hyundai, Kia, and Genesis can use a common underlying infotainment platform while presenting different interfaces and brand-specific graphics. In practical terms, the hardware or software foundation may be related, but a Kia’s menus, icons, screen layout, functions, and update behavior may differ from those of a Hyundai.
Hyundai Motor Group describes how a shared infotainment platform can support different Hyundai, Kia, and Genesis graphical identities in its engineering coverage of brand-specific interfaces.
The automakers have also collaborated on software and vehicle-control development, including model-based development and virtual validation for software-defined vehicles. That work is described in Hyundai’s report on Hyundai-Kia software collaboration.
4. Suppliers and manufacturing resources
Group companies can benefit from common suppliers, shared purchasing power, common engineering resources, and manufacturing facilities. A component supplier may serve both brands, and a manufacturing site may produce vehicles for more than one group brand depending on the plant, program, and market.
That does not mean every Hyundai and Kia is built in the same factory. Assembly location varies by model, production run, and country. For a particular vehicle, check its VIN, window sticker, owner documentation, or manufacturer records rather than inferring the factory from the corporate relationship.
What remains separate
Separate legal and financial identities
Kia Corporation has its own corporate name, board information, financial statements, investor-relations materials, shareholder disclosures, and stock-listing information. Hyundai Motor Company has separate corporate and stock information of its own.
U.S. regulators have also described Hyundai Motor Company and Kia Motors Corporation as “separate and distinct automotive manufacturers.” That regulatory description is older, but it illustrates the essential legal distinction: Kia is not simply a Hyundai model line.
The relevant references are Kia’s corporate information, Hyundai’s stock information, and the National Highway Traffic Safety Administration document describing the manufacturers separately.

Hyundai and Kia do not merely sell the same cars with different badges. They generally have different:
- Exterior styling and body designs
- Interior layouts and materials
- Infotainment presentation
- Model names and lineups
- Trim structures and available equipment
- Marketing and brand positioning
- Pricing strategies
- Suspension and steering tuning
- Feature availability by trim and market
Two vehicles can share an underlying platform and still feel substantially different on the road. Ride quality, steering response, seating position, cabin design, controls, noise insulation, powertrain calibration, and standard equipment can all be brand- or model-specific.
Separate dealers and service channels
Hyundai and Kia maintain separate authorized dealer and service channels. In the United States, Hyundai’s warranty materials direct Hyundai owners to authorized Hyundai dealerships, while Kia’s warranty information is administered through Kia’s authorized service network.
A Hyundai dealer may be capable of performing some routine mechanical work on a Kia, just as an independent repair shop may be able to service either brand. But an owner should not assume that a Hyundai dealer can automatically process Kia warranty work, campaign repairs, software updates, or parts claims. For warranty or manufacturer-covered work, follow the applicable brand’s warranty booklet and contact an authorized retailer for that brand.
Separate warranties
In the United States, both brands advertise a 10-year/100,000-mile powertrain warranty, but that headline does not make the warranties identical or transferable between brands.
- Hyundai: the 2026 U.S. warranty handbook states that the 10-year/100,000-mile powertrain coverage is generally for the original owner and is not transferable to subsequent owners, subject to the handbook’s specific provisions.
- Kia: Kia’s current U.S. warranty page states that its 10-year/100,000-mile powertrain warranty applies to the original purchaser and to the purchaser of a Certified Pre-Owned Kia, subject to the warranty’s restrictions.
Basic limited-warranty coverage, roadside assistance, electric-vehicle coverage, emissions coverage, anti-perforation protection, transferability, exclusions, maintenance requirements, and coverage for commercial or used vehicles can differ.
These are U.S.-specific examples. Warranty terms vary by country, model year, vehicle type, and purchaser status. Always read the warranty booklet for the exact vehicle rather than relying on the headline warranty length. See Hyundai’s 2026 U.S. warranty handbook and Kia’s current U.S. warranty information.
Are Hyundai and Kia vehicles the same underneath?
Sometimes they are technically close; they are not universally the same. A Hyundai and Kia may share a platform, engine family, transmission, battery architecture, electronic module, or supplier, while differing in body structure, wheelbase, suspension tuning, software, calibration, equipment, or interior.

For example, a Hyundai IONIQ electric vehicle and a Kia EV6 can be technical relatives because of their E-GMP foundation. That does not make them the same vehicle. Their exterior dimensions, cabin design, driving position, infotainment presentation, ride tuning, range figures, charging specifications, and available features can vary by model year and market.
The reverse is also important: vehicles that look similar in a showroom may not share every major component. A shared corporate group is not a substitute for checking the exact model, generation, drivetrain, and production year.
Why might one brand offer a feature the other does not?
Hyundai and Kia use related technology but position their products independently. One brand may make a feature standard on a particular trim while the other offers it only as an option, pairs it with a different package, or does not offer it in that market.
Those differences can result from:
- Different target buyers and brand positioning
- Trim and pricing strategy
- Packaging and available cabin space
- Model-year product planning
- Different regulatory or market requirements
- Different software interfaces and feature rollouts
- Design or driving-character priorities
Never assume that a Kia has a Hyundai’s feature—or that a Kia lacks it—simply because the vehicles share an architecture. Compare the window sticker and equipment list for the exact trim.
Do Hyundai and Kia share the same factories?
They can share manufacturing resources or facilities within the broader group, and related vehicles may be produced using common processes or suppliers. But there is no universal rule that Hyundai and Kia vehicles are built in the same factory.
Factory location depends on the vehicle, model year, market, and production program. If manufacturing origin matters to a purchase, verify it for the specific VIN or vehicle documentation. Corporate affiliation alone does not answer that question.
What this means when you are shopping
When comparing a Hyundai and a Kia, compare the individual vehicles, not just the parent-group relationship. A useful checklist is:
- Model and generation: Do not compare only the brand names. Identify the exact generation and body style.
- Model year: Engines, batteries, software, safety equipment, and warranty terms can change during a generation.
- Powertrain: Check the exact engine, hybrid system, motor, battery, transmission, and drive configuration.
- Trim and options: Standard safety equipment, cameras, driver assistance, lighting, audio, heated seats, and charging equipment can differ significantly.
- Ride and handling: A shared platform does not guarantee the same suspension or steering calibration.
- Service access: Consider whether an appropriate authorized dealer is convenient and experienced with the vehicle.
- Warranty eligibility: Confirm how coverage applies to the first owner, subsequent owners, and Certified Pre-Owned vehicles in your market.
- Recalls and campaigns: Check the actual VIN before buying.
- Insurance and financing: These are determined by the specific vehicle and buyer, not simply by group membership.
- Reliability information: Research the exact model year and drivetrain rather than applying a brand-wide assumption.
The shared group structure can provide economies of scale and spread new technology across both brands. It can also mean that closely related vehicles share some strengths—or occasionally some component-related risks. The final buying decision still belongs at the model-and-year level.

Recall checks must use the VIN
Do not assume a recall applies to both brands because two vehicles use a related engine, platform, or component. Hyundai and Kia recall campaigns can have different manufacturer names, recall numbers, production ranges, remedies, or affected vehicles.
Use the vehicle identification number through NHTSA’s recall lookup in the United States. VIN-based checking is more reliable than searching by a general model name or assuming that a related vehicle has the same campaign.
Parts are not automatically interchangeable
Shared ownership does not guarantee that a Hyundai part fits a Kia, or that a Kia part is approved for a Hyundai. Before ordering a replacement part, confirm:
- VIN
- Model year and generation
- Engine or motor code
- Transmission type
- Front-, rear-, or all-wheel drive
- Original part number and supersession information
- Connector and mounting configuration
- Software or calibration requirements
- Warranty and installation requirements
A component can look identical yet require different calibration, software, connectors, mounting hardware, or programming. Confirm compatibility with the manufacturer, an authorized dealer, or a qualified parts professional.
Reliability is not automatically shared
Hyundai and Kia can share components, so a component-specific reliability issue may affect related vehicles. But that does not mean a reliability result for one brand or model automatically applies to the other.
Production dates, software versions, supplier changes, calibrations, recalls, warranty extensions, maintenance schedules, and vehicle applications can differ. For a useful reliability assessment, research the exact model, model year, engine or EV system, and known service campaigns.
Common misconceptions
“Kia is just a rebadged Hyundai.”
Not generally. Some Hyundai and Kia vehicles are engineering relatives, but the brands can use different body designs, interiors, feature packages, software interfaces, calibrations, suspension tuning, and model strategies.
“Hyundai owns 51% of Kia.”
That describes the original acquisition stake, not the latest public ownership information. Hyundai Motor Company’s current Kia holding is roughly 35%, based on Kia’s end-of-2025 ownership disclosure.

Best Value
“Hyundai owns 100% of Kia.”
No. Kia remains a separately listed company with its own shareholders, board information, financial reporting, and corporate identity.
“A Hyundai recall must apply to the equivalent Kia.”
Not necessarily. Recall eligibility is vehicle- and VIN-specific. Check the actual vehicle through the relevant manufacturer or NHTSA in the United States.
“A Kia warranty can be used at any Hyundai dealer.”
Do not assume that. Routine service may be possible in some circumstances, but warranty work and manufacturer campaigns should be handled according to the applicable brand’s authorized-service requirements.
The practical rule to remember
For everyday decisions, treat Hyundai and Kia as separate automakers when you are:
- Buying or selling a vehicle
- Checking a recall
- Making a warranty claim
- Choosing a dealer
- Ordering parts
- Comparing insurance or financing
- Researching reliability
At the same time, treat them as closely related group companies when you are evaluating:
- Vehicle platforms
- Powertrain families
- EV architecture
- Infotainment and software foundations
- Suppliers and manufacturing scale
- Group-level technology development
Frequently Asked Questions
Does Hyundai own all of Kia?
No. Hyundai Motor Company is Kia’s largest shareholder, with roughly 35% of Kia based on Kia’s latest publicly reported ownership information. Kia is not a wholly owned Hyundai subsidiary and has its own shareholders, board information, financial reporting, and stock listing.
Are Kia and Hyundai cars identical?
No. Some vehicles share platforms, engines, transmissions, batteries, electronics, or software foundations, but their body designs, interiors, features, calibrations, suspension tuning, pricing, and model-year specifications can differ.
Can a Hyundai dealer service a Kia?
A Hyundai dealer may be able to perform some routine work, but owners should not assume it can process Kia warranty repairs, software updates, or manufacturer campaigns. For covered work, follow Kia’s warranty requirements and contact a Kia-authorized retailer. The same principle applies in reverse.
Do Hyundai and Kia recalls automatically apply to both brands?
No. Recalls can use different affected-vehicle lists, production dates, recall numbers, remedies, and filing manufacturers. Check the specific vehicle identification number through the manufacturer or, in the United States, NHTSA’s recall lookup.
Are Hyundai and Kia warranties the same?
No. In the United States, both brands advertise a 10-year/100,000-mile powertrain warranty, but eligibility and transferability differ. Hyundai’s cited 2026 handbook generally limits that coverage to the original owner, while Kia’s current U.S. program also identifies purchasers of Certified Pre-Owned Kias, subject to restrictions. Other warranty categories and terms also vary by brand, country, model year, and vehicle.
Why do Hyundai and Kia use similar engines and platforms?
They are part of the same Hyundai Motor Group, allowing substantial cooperation in engineering, purchasing, software, supplier relationships, and manufacturing. Shared foundations reduce development costs and help distribute technology while still allowing each brand to create different vehicles.
Is Genesis part of the same group?
Yes. Genesis is part of the broader Hyundai Motor Group automotive family, alongside Hyundai Motor Company and Kia. Genesis is a distinct premium brand and should not be treated as the same consumer brand as Hyundai or Kia.
Why do some websites still say Hyundai owns 51% of Kia?
They are usually referring to the original late-1990s acquisition stake. The acquisition agreement and bid period date to 1998, while the historical filing records payment in March 1999. Kia’s latest public ownership information now shows Hyundai Motor Company with roughly 35%, so 51% should be identified as historical rather than current.
The Bottom Line
Hyundai and Kia are not the same company. Hyundai Motor Company and Kia Corporation are separate, publicly listed automakers within Hyundai Motor Group. Hyundai Motor Company owns roughly 35% of Kia and has major strategic influence, while Kia retains its own corporate identity, brand, vehicles, dealers, warranties, and financial reporting.
They share plenty of technology and resources—including platforms, components, software work, suppliers, and some manufacturing capabilities—but that does not make every Hyundai and Kia interchangeable. For a purchase, repair, warranty claim, parts order, or recall, use the exact model, model year, drivetrain, and VIN.
