2024-2026 Tesla Model 3 Door Mirror: A Guide to 'Highland' Compatibility and Replacement
This guide covers the critical differences, common failure points, and replacement process for the side view mirror on the refreshed 2024+ Tesla Model 3 'Highland'.
- This mirror ONLY fits the 2024-2026 'Highland' Model 3; parts from 2017-2023 models are not compatible.
- The most common failures are related to the power-folding motor getting stuck or physical damage from impacts.
- When buying used, verify the part number and inspect the glass for auto-dimming failure (discoloration).
- Replacement is DIY-friendly if you are comfortable removing the interior door panel, but watch for imperfect fitment on cheaper aftermarket parts.
Crucial Compatibility Warning: 'Highland' vs. Pre-Refresh Models
Warning: The door mirrors for the 2024-2026 Tesla Model 3, often called the 'Highland' refresh, are NOT compatible with earlier 2017-2023 Model 3 vehicles. The housing, mounting points, and overall design were changed for the 2024 model year. Many online sellers incorrectly list these parts as fitting '2017-2024', which is a common and expensive mistake for buyers. Always verify the part number and confirm it is from a 2024 or newer 'Highland' model before purchasing.
Symptoms of a Failing Door Mirror
While the 'Highland' Model 3 is still new, its mirrors share technology with earlier models, and they can exhibit similar failure symptoms over time. Here’s what to look out for:
- Power Fold Failure: The mirror may get stuck, refuse to fold or unfold, or make a grinding noise. This can be caused by debris in the mechanism, ice buildup in cold climates, or motor failure. Sometimes a software glitch can cause intermittent issues.
- Mirror Glass Fails to Adjust: The adjustment motor inside may fail, preventing you from positioning the mirror glass correctly.
- Auto-Dimming Malfunction: The auto-dimming feature, which darkens the mirror to reduce glare, can fail. This often appears as a brownish or yellowish discoloration, a 'lava lamp' look, or a clear line separating the dimmed and undimmed areas.
- Heater Inoperative: The heating element, which works with the rear defroster, may stop working. This becomes obvious in cold or damp weather when the mirror fails to clear frost or condensation.
- Vibrating Glass: The mirror glass itself may become loose and vibrate excessively at speed, making it difficult to see clearly.
- Physical Damage: The most common issue is physical damage from impacts, resulting in a cracked mirror housing, broken glass, or a non-functional LED turn signal strip.
Pro Tip: If your mirror is stuck and won't fold, first check for ice or debris in the hinge. You can try to reset the function through the touchscreen controls (Controls > Mirrors > Fold/Unfold). Forcing the mirror by hand can damage the internal gears.
Buying a Used Door Mirror: What to Check
Purchasing a used OEM mirror is an excellent way to save money while ensuring a perfect fit and function. However, you must be a careful shopper, especially with this part.
1. Verify 'Highland' Compatibility
This is the most important step. A mirror from a 2023 or older Model 3 will not fit. When buying online, look for listings that specifically state '2024+', 'Highland', or show a clear picture of the part number. Be skeptical of listings with a wide year range like '2017-2025'. The primary part number for the left (driver) side is 1592031-00-H, but you may also see other revisions like 1592031-00-G or 2097804-00-A.
2. Physical Inspection Checklist
- Main Housing: Check for any cracks, deep gouges, or broken tabs, especially around the mounting points.
- Mirror Cap: The painted top cover is often a separate piece. It may have scratches, but it can typically be swapped from your old mirror if the color doesn't match.
- Mirror Glass: Inspect the glass closely for any browning or delamination, which indicates a failed auto-dimming feature.
- Turn Signal LED: Look for cracks in the clear plastic strip. Moisture inside the lens is a red flag.
- Electrical Connector: Examine the pins inside the connector. They should be straight and free of any green or white corrosion.
3. Why Used OEM is Better Than New Aftermarket
For a complex electronic part like a Tesla mirror, a used OEM unit is often a safer bet than a cheap, new aftermarket one. OEM ensures that the power folding, heating, and auto-dimming functions will work correctly with the car's software. Aftermarket parts can sometimes have issues with fitment or electronic compatibility, as seen in some installation videos where the mirror doesn't sit perfectly flush.
Known Issues, TSBs, and Recalls
As of early 2026, there are no specific NHTSA recalls or Technical Service Bulletins (TSBs) for the door mirrors on the 2024-2026 Tesla Model 3. While other recalls exist for these model years concerning issues like the rearview camera display, they do not involve the side mirror assemblies.

Frequently Asked Questions (FAQ)
Do I need to program a new mirror?
No, a replacement mirror assembly for the Model 3 is typically plug-and-play and does not require special programming. The car should recognize it automatically. However, on older models, if the mirror was replaced due to an internal short, a body controller reset via Service Mode might be needed.
Will a mirror from a 2023 Model 3 fit my 2025 Model 3?
No, absolutely not. The 2024 'Highland' refresh introduced a completely different mirror design. You must use a mirror from a 2024, 2025, or 2026 Model 3.
Can I just replace the mirror glass instead of the whole assembly?
Yes. If only the glass is broken, it can be replaced separately. The glass is held on by clips and has electrical connectors for the heater and auto-dimming features. The process involves carefully prying the old glass off and snapping the new one in place.
🎬 Watch this guide to replacing your side mirror glass.Is the painted mirror cap replaceable?
Yes, the top painted cover (or 'skull cap') is a separate piece that can be removed and swapped over from your old mirror. It is held on by clips and can be carefully pried off. This allows you to buy a used mirror of any color and reuse your original color-matched cap.
