2024-2026 Tesla Model 3 'Highland' Side Mirror: Folding Failures, Camera Calibration, and Replacement
This guide covers the critical compatibility warnings, common problems, and replacement procedures for the side view mirror on the redesigned 2024+ Tesla Model 3 'Highland'.
- This mirror ONLY fits the 2024-2026 'Highland' Model 3; parts from 2017-2023 models are not compatible.
- After replacement, the car requires a camera calibration drive of 20-25 miles for Autopilot features to function.
- Common failures include the power-folding motor getting stuck and physical damage from impacts.
- When buying used, verify the part number (LH: 1592031-xx-H, RH: 1592032-xx-H) and inspect the camera lens for damage.
Key Compatibility Warnings for the 2024+ Model 3 'Highland'
Warning: The side view mirrors for the 2024-2026 Tesla Model 3, known as the 'Highland' refresh, are NOT backward compatible with earlier 2017-2023 Model 3 vehicles. The mirror housing, aerodynamic shape, and mounting points were completely redesigned. Many online sellers incorrectly list these parts as fitting a wider range of years, which can lead to an expensive purchasing mistake. Always verify you are buying a mirror from a 2024 or newer 'Highland' model.
Autopilot Hardware 4 (HW4) Only: This mirror assembly contains a camera that is integral to the Autopilot Hardware 4 system. It is not compatible with older hardware versions. Using an incorrect or incompatible mirror can cause Autopilot, lane change assist, and other driver-assistance features to fail.
Common Symptoms of a Failing Side View Mirror
While the 'Highland' Model 3 is still relatively new, its mirrors contain technology similar to other Tesla models. Failures typically fall into a few categories:
- Power-Folding Failure: The mirror may get stuck in the folded or unfolded position, move slowly, or make a grinding noise. This can be caused by debris in the hinge, ice buildup, a failing motor, or a software glitch. Some owners have reported folding issues after software updates.
- Mirror Glass Fails to Adjust: The internal motor that controls the glass position may fail, preventing you from aiming the mirror correctly.
- Camera Malfunction: A failure of the internal side repeater camera will trigger warnings on the touchscreen and disable Autopilot features that rely on that camera's input.
- Heating Element Failure: The defrost function may stop working, leaving the mirror obscured by ice or fog in cold weather.
- Auto-Dimming Fluid Leak: The electrochromic fluid in the auto-dimming glass can fail, often showing a brownish or yellowish line, a 'lava lamp' effect, or a permanent dark tint that impairs visibility.
- Vibration at Speed: While a Technical Service Bulletin for this issue was released for the Cybertruck, it's possible for the Model 3 mirror to vibrate or shake excessively at highway speeds, making the reflection blurry. This could be caused by a loose assembly or an issue with the door panel itself.
Buying a Used 2024-2026 Model 3 Side Mirror: What to Check
A used OEM mirror is often an excellent value compared to a new part, but careful inspection is key. Here’s what to look for:
- Verify the Part Number: This is the most important step. Ensure the part number matches the 'Highland' generation. The left (driver) side is typically 1592031-xx-H and the right (passenger) side is 1592032-xx-H. Do not trust a listing that claims to fit both pre- and post-2024 models.
- Inspect the Housing and Mounting Points: Check for any cracks, deep scuffs, or damage to the three bolt-on mounting points. The mirror should be structurally sound.
- Check the Camera Lens: The side repeater camera lens should be clear, without scratches, condensation, or yellowing. A damaged lens will render it useless for Autopilot.
- Examine the Electrical Connector: Look at the main electrical connector and its pins. Ensure there is no corrosion, bent pins, or damage to the wiring harness.
- Test the Folding Mechanism (If Possible): If buying from a local seller, ask them to connect it to a power source to test the folding motor. Listen for smooth, quiet operation.
- Inspect the Mirror Glass: Look for the tell-tale signs of auto-dimming failure, such as discoloration or fluid lines. Ensure the glass is not chipped or cracked.
- The Mirror Cap is Swappable: The painted top cover (or 'skull cap') is a separate piece that can be unclipped and replaced. If you find a used mirror in the wrong color but your original cap is undamaged, you can easily swap it over, saving on paint costs.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
As of early 2026, there are no specific NHTSA recalls for the side view mirror assemblies on the 2024-2026 Tesla Model 3. While numerous recalls exist for these model years, they pertain to other systems like rearview cameras, TPMS sensors, or software-related font sizes.
A service bulletin (SB-25-10-002) was issued for the Tesla Cybertruck to address shaking side mirrors at high speed, a condition caused by vibrations in the door assembly. While not specific to the Model 3, it highlights a potential issue to be aware of if you experience excessive mirror vibration.
Replacement Overview & Camera Calibration
Installation Steps
Replacing the side mirror assembly is a feasible DIY project for those comfortable with basic tools. The official Tesla flat rate time is just 0.24 hours.
- Lower the Window: Fully lower the window in the door you are working on.
- Remove the Door Trim Panel: This is the most involved step. The door panel must be removed to access the mirror's connector and mounting bolts.
- Disconnect the Harness: Locate the single electrical connector for the mirror and disconnect it.
- Remove the Bolts: Remove the three 10mm bolts that secure the mirror assembly to the door frame.
- Install the New Mirror: Guide the new mirror's wiring harness through the door and position the mirror. Install the three bolts and torque them to 15 Nm (11.1 lb-ft).
- Reconnect and Reassemble: Connect the electrical harness, reinstall the door panel, and test all functions (adjustment, folding, turn signal).
Pro Tip: Tesla's service manual notes that if you are replacing a mirror due to a short in the adjustment motor, you may need to reset the corresponding body controller through the car's Service Mode to clear the circuit protection and restore function to the new mirror.
Required Camera Calibration
Important: After replacing a side mirror, you MUST perform a camera calibration. The Autopilot system needs to learn the precise position of the new camera. To do this:
- The car will automatically start the process. A progress indicator will appear on the touchscreen.
- Drive the vehicle for 20-25 miles (32-40 km) on a straight, multi-lane highway with clear lane markings for the fastest results.
- Autopilot and other related features will be disabled until calibration is complete.
- If needed, you can manually reset the process by navigating to Controls > Service > Camera Calibration > Clear Calibration on the touchscreen.
Cost Comparison: New vs. Used
| Part Type | Estimated Cost | Notes |
|---|---|---|
| New OEM | $700 - $800 | Purchased directly from Tesla or an OEM parts supplier. |
| New Aftermarket | Not Widely Available | As of mid-2026, complete aftermarket assemblies for the 'Highland' are not common. |
| Used OEM | $300 - $450 | A significant savings. Commonly found on recycler sites and eBay. |
| Shop Labor | $100 - $250 | Typically 1-1.5 hours of labor at an independent shop. Tesla service center labor rates may be higher. |
Frequently Asked Questions (FAQ)
Do I need to have the new mirror painted?
Not necessarily. The colored mirror cap is a separate component that can be carefully unclipped from the old mirror and snapped onto the new one. If your original cap is undamaged, you can reuse it and avoid painting costs.
Can I fix a mirror that won't fold?
Sometimes. First, try resetting it using the on-screen controls (Controls > Mirrors > Fold/Unfold). Also, check for and clean any dirt, ice, or debris from the folding hinge. If the motor is making a grinding noise or is completely dead, the entire assembly will likely need to be replaced.
🎬 Watch: How to fix stuck or non-folding mirrorsWill replacing the mirror fix my Autopilot error message?
If the error message is related to the side repeater camera and diagnostics have confirmed the camera in the mirror has failed, then yes, replacing the assembly should resolve the issue after a successful camera calibration.
Is it illegal to drive with a broken side mirror?
Yes, in most places it is illegal to drive without a functional driver-side side view mirror. A missing or broken passenger-side mirror may also be a violation depending on local laws. It also significantly reduces your situational awareness and increases crash risk.
