Mobis EPC Explained: Hyundai, Kia & Genesis

Brands and models

One catalog family covers three fast-growing marques:

• Hyundai: Tucson, Elantra, Santa Fe, i30, Kona
• Kia: Sportage, Ceed, Sorento, Rio, Seltos
• Genesis: G70, G80, GV70, GV80

Shared platforms, real differences

Hyundai, Kia and Genesis share platforms, engines and a great deal of hardware, which is exactly why VIN-level identification matters more here than at makers with separate model lines. A Tucson and a Sportage are close cousins underneath. Many suspension, cooling and driveline components are common, and many others are not, because each brand tunes and trims its own version.

The parts that most often differ are the ones the customer sees or feels: front and rear bumpers, lighting, grilles, interior trim, and anything to do with spring and damper rates. A Sportage damper is not a Tucson damper even when the strut looks identical on the bench. Body panels diverge completely, because the brands share structure but not skin.

Model year is the second trap. The group runs relatively short product cycles and applies running changes freely, so a part that fitted a 2021 build can be superseded or split by the 2023 facelift. Decode the VIN and Mobis narrows it to the exact component fitted to that car. Search by model name and you are choosing between several plausible numbers with nothing to separate them.

Reading a Korean part number

Mobis numbers follow a consistent shape that is worth learning, because it tells you something before you open a diagram. A number such as 58101-2W000 splits into two blocks: the first five digits identify the part type, and the second five identify the application.

The leading block is stable across the whole group. 58101 is a front brake pad kit whether the badge on the car says Hyundai, Kia or Genesis. The second block carries a platform code, in this case 2W, followed by a variant number. That is why two numbers that differ only in the middle characters are usually the same component for two different vehicles rather than two different components.

The practical use of this is quick sanity checking. If a supplier quotes a number whose first five digits do not match the part type you asked for, something has gone wrong in the conversation before any money changes hands. You can check the shape of any number against the manufacturer house formats with the free part number lookup on this site.

Keeping numbers current

Mobis keeps OEM numbers and supersession chains current across all three brands, and the group revises parts often enough that this is not a formality. A Korean number that was correct last year may have been replaced since, sometimes more than once, and the replacement occasionally arrives as a kit where the original was a loose component.

The chain matters as much as the endpoint. When a number has been superseded twice, ordering the middle number in the chain may still find old stock somewhere, and that stock is the superseded design that was replaced for a reason. Following the chain to its current end is the only way to be sure you are fitting what the manufacturer now specifies.

Market differences that catch people out

The same car wears different names in different markets, and the catalog knows the market from the VIN rather than from the name. A European i30 and a North American Elantra GT are close relatives with different badges, and a Kia Ceed sold in Europe has no direct North American twin at all.

Emissions and equipment specifications move parts as well. Vehicles built for markets with stricter emissions regimes carry different exhaust and after-treatment hardware, and cold-climate packages add heating elements that simply are not present on the same model sold elsewhere. Ordering against the VIN sidesteps all of it, because the build record already contains the market.

Accessing Mobis online

Dealer software is the traditional route and it comes with dealer conditions: an account, an installation, and a machine it is tied to. VINsearch reads the same Mobis data in the browser alongside every other major catalog, so a workshop that sees a Tucson in the morning and a Transit in the afternoon does not need two systems and two logins.

For an independent shop the practical value is coverage without commitment. One login covers Hyundai, Kia and Genesis plus 49 more catalogs on any device, which matters when the mix of cars through the door is decided by the local market rather than by a franchise agreement.
