Hyundai and Kia share a catalog. Here is what that actually means at the counter
What actually crosses the badge
Powertrain hardware travels furthest. Engines, gearboxes, cooling components and a lot of what bolts to them are shared across the group, and a number found on a Kia job will often be the number a Hyundai needs. Suspension and braking follow the platform rather than the badge, so they cross more often than not.
Bodywork and interior trim are where it stops. The two brands style separately on purpose, so bumpers, lights, grilles, mirrors and almost everything you can see from the driver’s seat are brand-specific even when the metal underneath is identical. This is the boundary that catches people out, because the shared parts have already trained them to expect the interchange.
Genesis is the third brand in the room
Genesis is Hyundai’s luxury line and sits in the same catalog. Its cars carry more equipment variation than the mainstream models, which means more places where two apparently identical vehicles want different parts.
If you have looked up a Hyundai before, you already know how to look up a Genesis. Our guide to Mobis EPC and Snap-on EPC covers the catalog across all three brands.
Why the VIN matters more here than the interchange table
The temptation with a shared catalog is to work from a cross-reference list rather than the car. That works until it does not, and the failure is quiet: the part fits the platform, arrives, and turns out to be the version fitted to the other brand or the other market.
Feeding the VIN in first costs a few seconds and answers the question the interchange table only approximates. See how to find a part number for the habit applied generally.
Korean cars built outside Korea
Hyundai and Kia build in the Czech Republic, Slovakia, Turkey, India, the United States and elsewhere, and the plant changes what the car got. A Tucson built in Europe and one built in Korea can differ in emissions hardware, cooling and equipment even in the same model year.
The VIN carries the plant, which is why the catalog resolves this correctly and a model-and-year search does not.
Frequently asked questions
Can I fit a Kia part to a Hyundai?
Often yes for powertrain and chassis hardware on a shared platform, and rarely for bodywork or interior trim. Confirm it against the VIN rather than the platform.
Is Genesis in the same catalog?
Yes. Genesis is Hyundai’s luxury brand and sits in the same Snap-on EPC as Hyundai and Kia.
Why do two identical Tucsons take different parts?
They may have been built in different plants for different markets, which changes emissions hardware, cooling and equipment. The VIN carries the build plant.
