Genuine Hyundai 85101-3X100 Inside Rear View Mirror, Day/Night | Hyundai & Kia

Genuine Hyundai 85101-3X100 Inside Rear View Mirror (Day/Night)

Did your rear view mirror pop off the windshield button, wobble on the mount, or turn hazy and dark around the edges? The genuine Hyundai/Kia 85101-3X100 inside mirror assembly is the factory replacement — the same day/night mirror installed on a wide range of Hyundai and Kia models.

This is the standard manual mirror: a prismatic glass element with a day/night flip lever that cuts headlight glare at night. It slides onto the factory windshield-mounted button with a spring clip — push it on until it clicks and you are done.

Product Type

Interior Rear View Mirror Assembly (manual day/night type)

Function

Mounts on the windshield button and gives the driver a clear rear view. Flipping the lever tilts the prismatic glass to reduce glare from headlights behind you at night. This is the manual, non-electric version — it replaces the standard mirror on vehicles without auto-dimming.

FAQ

Will this fit my Hyundai or Kia?

It fits a wide range of 2009–2024 Hyundai and Kia models listed above. Please verify with your VIN before ordering.

Is this a genuine part?

Yes. This is a genuine Hyundai/Kia mirror assembly, part number 85101-3X100, shared across both brands.

Does it auto-dim or have HomeLink buttons?

No. This is the standard manual day/night mirror — no electrochromatic dimming, HomeLink, or compass. If your original mirror auto-dims or has buttons, this is not the correct replacement.

How hard is the installation?

No tools needed: slide the mirror base onto the factory windshield button until the spring clip snaps in place.

My mirror glass is hazy — is that fixable?

Hazing and delamination happen inside the glass element and cannot be repaired. Replacing the mirror assembly restores a clear view.
