2020-2022 Genesis G90 Rear Vanity Mirror Lamp: Diagnosis and Replacement
A guide to fixing a faulty rear vanity mirror light in your G90 and what to inspect when purchasing a used OEM replacement.
- The rear vanity lamp is an integrated LED module; the bulb cannot be replaced separately, requiring a full assembly replacement.
- The OEM part number is 85381-D2600, and it fits both the left and right rear passenger positions.
- Replacement is a very simple DIY task that takes less than 15 minutes and only requires a plastic trim tool.
- There are no known recalls or common defects for this part, so failure is typically an isolated incident.
Symptoms of a Failing Rear Vanity Mirror Lamp
Failure of the rear vanity mirror lamp in a 2020-2022 Genesis G90 is typically straightforward to diagnose. Because this is a simple, integrated LED unit, problems are almost always contained within the lamp assembly itself.
- Light Does Not Turn On: The most common symptom is a complete failure to illuminate when the passenger vanity mirror is opened.
- Flickering or Intermittent Light: The LED may flicker, flash, or work only some of the time. This often points to a failing internal circuit board or a loose connection within the lamp housing.
- Dim or Discolored Light: An aging or failing LED module can produce light that is noticeably dimmer than the other interior lights or has a different color temperature, which can be disruptive to the cabin's cohesive lighting scheme.
Pro Tip: Before assuming the lamp has failed, check the fuse. While unlikely to be the cause for a single light failure, it's a quick and easy diagnostic step. The interior fuses are located in a panel on the driver’s side of the dashboard.
Known Issues, TSBs, and Recalls
As of mid-2026, there are no widespread known issues, Technical Service Bulletins (TSBs), or NHTSA recalls specifically related to the rear vanity mirror lamps on the 2020-2022 Genesis G90. Failures of this component appear to be isolated incidents rather than the result of a manufacturing or design defect. The G90 has had recalls for other components, such as the fuel pump and certain engine parts, but none involve the interior lighting system.
Buying a Used 2020-2022 G90 Rear Vanity Lamp
Since a new OEM replacement lamp from a Genesis dealer can be surprisingly expensive, a used OEM unit is often the most cost-effective solution. Aftermarket versions of this specific part are not commonly available. When buying a recycled part, pay close attention to the following details to ensure you get a quality component.
Key Inspection Points:
- Verify the Part Number: The correct OEM part number for this assembly is 85381-D2600. You may see a suffix like '-VNB' which indicates the interior color (e.g., beige). Confirm the color of the housing matches your vehicle's headliner.
- Inspect the Lens: Check the clear plastic lens for any cracks, deep scratches, or haziness. A damaged lens will diffuse the light poorly and look out of place.
- Examine the Housing and Tabs: Look at the entire plastic body of the lamp. Ensure there are no cracks and, most importantly, that all mounting tabs are intact. These tabs are critical for securing the lamp flush against the headliner.
- Check the Electrical Connector: The connector pins should be straight, clean, and free of any corrosion or signs of water damage. A damaged connector will prevent the lamp from working.
Warning: This lamp assembly is the same for both the rear left (driver side) and rear right (passenger side) positions.

Installation Guide
Replacing the rear vanity lamp is a simple task that most owners can complete in under 15 minutes with a single tool. The Genesis owner's manual advises having this service performed by a dealer because it is an integrated LED unit, but this is primarily a precaution to prevent cosmetic damage to the headliner.

Frequently Asked Questions (FAQ)
Is the bulb replaceable, or do I need the whole lamp assembly?
You must replace the entire lamp assembly. The 2020-2022 G90 uses an integrated LED module, not a traditional removable bulb.
Does this part fit the front sun visor vanity mirrors?
No, this part (85381-D2600) is specifically for the rear passenger vanity mirrors located in the headliner. The front sun visor lights are a different part.
Is the lamp the same for the left and right rear seats?
Yes, this lamp assembly is interchangeable and fits both the left and right rear positions.
Why is my new lamp a different color than the other interior lights?
If you installed a non-OEM part, its color temperature may not match the factory lighting. This is a primary reason why choosing a used OEM part is recommended over a cheap aftermarket alternative, as it guarantees a perfect match with the rest of the G90's ambient lighting.
