2017-2026 Tesla Model 3 & Y Rear View Mirror: Framed vs. Frameless and Highland/Juniper Guide

A Critical Compatibility Warning: Framed vs. Frameless Mirrors

The most important factor when replacing the interior rear-view mirror on a Tesla Model 3 or Model Y is the vehicle's production date, which determines the mirror style. The two main types—framed and frameless—have different mounting systems and are not interchangeable. Installing the wrong version is not possible without modifying the vehicle.

Standard Framed Mirror

This is the original mirror style, featuring a visible plastic frame around the glass. It is the standard auto-dimming mirror for the following vehicles:

• 2017-2023 Tesla Model 3 (All models built before the 'Highland' refresh)
• 2020-2024 Tesla Model Y (All models built before the 'Juniper' refresh)

Common part numbers for this version begin with 1119904.

Frameless Mirror

With the introduction of the 'Highland' refresh, Tesla updated the interior with a sleeker, frameless rear-view mirror that has no visible plastic bezel around the glass. This mirror fits:

• 2024-2026 Tesla Model 3 ('Highland' refresh)
• 2025-2026 Tesla Model Y ('Juniper' refresh)

Common part numbers for this version begin with 1494441.

Symptoms of a Failing Rear View Mirror

Failure of the auto-dimming mirror can range from a minor annoyance to a genuine visibility issue. Here are the most common symptoms:

• Auto-Dimming Malfunction: The most frequent problem is a failure of the auto-dimming feature. This can include the mirror being stuck in a dark state during the day, failing to dim at night, or flickering between light and dark.
• Bubbles or "Lava Lamp" Effect: The seal on the electrochromic gel can fail, allowing air to enter and creating bubbles or a discolored, distorted area within the glass. This damage is permanent and requires replacement.
• Fluid Leakage: In severe cases, the electrochromic fluid can leak from the mirror housing. This fluid is corrosive and can permanently damage interior plastics and upholstery.
• Loose Mirror or Vibration: The mirror assembly itself can become loose on its mount, causing it to vibrate or sag while driving.

• Rattling Noises: Many owners report rattling or buzzing noises coming from the plastic housing that surrounds the mirror and front camera assembly. This is often due to the plastic covers, not the mirror itself.

Buying a Used Interior Rear View Mirror

A used OEM mirror can be a cost-effective replacement, but careful inspection is key to getting a good part.

1. Confirm the Version: First and foremost, confirm you are buying the correct style (framed or frameless) for your vehicle's year and model. Ask the seller for a clear photo if you are unsure.
2. Inspect the Glass: Carefully examine the mirror glass for any signs of internal bubbles, discoloration, or dark spots. Hold it up to a light. Any indication of a failing electrochromic layer means the part should be rejected.
3. Check the Mount and Housing: Ensure the mounting stalk is not cracked or damaged. For pre-Highland models, this is the part that twists onto the windshield bracket. For frameless mirrors, inspect the entire mounting assembly. The plastic housing should also be free of cracks.
4. Examine the Electrical Connector: The pins in the electrical connector should be straight and free of corrosion. A damaged connector will prevent the auto-dimming feature from working.

Replacement Procedure Overview

Replacing the interior rear-view mirror is a straightforward DIY task that typically takes less than 30 minutes. The procedure varies slightly between the older framed mirrors and the newer frameless versions.

For 2017-2023 Model 3 & 2020-2024 Model Y (Framed Mirror)

1. Remove the Plastic Covers: Carefully pry off the two large plastic pieces that cover the mirror stalk and forward camera assembly. They are held on by clips.
2. Disconnect the Electrical Connector: Unplug the single wiring harness attached to the back of the mirror.
3. Remove the Mirror: Firmly grip the mirror's stalk (the metal base), not the mirror body itself, and twist it counter-clockwise about 45-90 degrees to release it from the bracket on the windshield.
4. Installation: To install the new mirror, connect the electrical plug, align the mirror on the mount at an angle, and twist it clockwise until it locks into place. Snap the plastic covers back on.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

There are no major recalls or TSBs specifically for the physical interior rear-view mirror itself. However, there is a common point of confusion regarding a recall for the "rearview" system.

NHTSA Recall 25V-002 (Tesla Recall SB-25-00-001): This recall affects some 2023-2025 Model Y and 2024-2025 Model 3 vehicles. It addresses a software issue where the backup camera image may fail to appear on the center touchscreen. This is a software and computer problem, not an issue with the physical interior mirror. The fix is a free over-the-air (OTA) software update.

Some owners of the Model Y have complained that the combination of the factory-tinted rear glass and the auto-dimming mirror makes rearward visibility too dark at night. A common, unofficial fix for this is to unplug the mirror's electrical connector to disable the auto-dimming feature.
