On this vehicle, the interior covers cabin hardware — seat components, handles, switch bezels, carpet, pedals and the pieces that take daily wear.

- Read the notes on each row for position, trim and spec qualifiers before you order.
- Where labor overlaps, replace the retainer clips with any panel removal — they are cheap insurance against squeaks.
- Cross-reference the manufacturer part number against your old part or a service-manual listing.

Our catalog currently lists 72 interior parts for the 2018 Hyundai Ioniq across 6 subcategories and 6 brands, covering both the 1.6L L4 ELECTRIC/GAS and the ELECTRIC. Each part is matched to the engine(s) it fits.
Do interior parts differ between 2018 Hyundai Ioniq engines?
Some do. 17 parts fit every engine; the other 55 are engine-specific. Each row (and the filter at the top) shows which. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.
What are the signs of interior problems on a 2018 Hyundai Ioniq?
Common symptoms include a door handle that works only from outside, sagging headliner, a window switch that needs two presses, or seat adjusters that stick. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.
What should I replace at the same time?
Where labor overlaps, replace the retainer clips with any panel removal — they are cheap insurance against squeaks.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2018 Hyundai Ioniq was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2018 Hyundai Ioniq?
First match the engine — each row shows which engine(s) the part fits. Then interior plastics are often color- and trim-specific — check the notes column against your trim level before ordering. The notes column carries position and trim qualifiers where they apply.
