2019-2024 Acura MDX Forward Camera: ADAS Faults, Calibration, and Replacement Guide

Camera vs. Radar: Identifying the Correct Part

The 2019-2024 Acura MDX uses several cameras and sensors. A failure in one can be easily confused with another. Before purchasing a part, it's critical to identify which component has failed based on the symptoms.

• Forward Multipurpose Camera: This is the main subject of this guide. It's a single camera located behind the rearview mirror. A failure here will trigger multiple ADAS warnings on the dash, such as 'Collision Mitigation System Problem' and 'Lane Keeping Assist Problem'. Part numbers often begin with 36163.
• Rearview Camera: This camera is mounted on the tailgate and activates when the vehicle is in reverse. A failure typically results in a black, flickering, or distorted image on the main infotainment screen. Part numbers often begin with 39530.
• Surround View Cameras: On higher trims (like the Advance Package), small cameras are located in the front grille, under the side mirrors, and on the tailgate. These create the 360° bird's-eye view for parking. A failure in one of these cameras will result in a black or distorted section of the 360° view.
• Forward Milliwave Radar: This is a radar sensor, not a camera, located behind the Acura emblem in the front grille. It works with the forward camera for ACC and CMBS. Part numbers often begin with 36801 or 36803.

Common Symptoms of a Failing Forward Camera

A bad forward camera typically does not affect the main infotainment screen. Instead, it disables the advanced safety features that rely on its input.

Multiple ADAS Warning Lights

The most common sign of failure is a sudden cascade of warning lights and messages on the instrument panel. You will likely see all of the following errors appear at once:

• Collision Mitigation Braking System (CMBS) Problem
• Lane Keeping Assist System (LKAS) Problem
• Adaptive Cruise Control (ACC) Problem
• Road Departure Mitigation (RDM) System Problem
🎬 Watch: How to resolve these dashboard warning lights

When these lights are on, the corresponding safety features are disabled. Your vehicle will drive normally, but automatic emergency braking, lane centering, and adaptive cruise will not function.

Heat-Related Failures

Many owners report that these failures begin on hot, sunny days. The camera unit, located in a black housing against the hot windshield, can overheat and malfunction. In some cases, the errors may disappear after the vehicle cools down, only to return the next time it gets hot. This intermittent behavior is a strong indicator that the camera itself is failing.

False CMBS Activations

In some instances, the system may activate incorrectly, causing the vehicle to brake suddenly and unexpectedly for non-existent threats. Owners have reported this happening for steel road plates, construction cones, or even while navigating a curve on the highway. While this can be caused by a dirty sensor or unusual road conditions, it can also be a symptom of a malfunctioning camera or radar system.

Known Issues, TSBs, and Recalls

As of early 2026, there are no active recalls specifically for the forward-facing camera on the 2019-2024 Acura MDX. However, the failure of this component is a widely documented complaint among owners.

Rearview Camera Display Recall (2025 Models): It is important not to confuse forward camera issues with a recall issued for some 2025 MDX models (NHTSA ID: 25V-032). This recall addresses a software problem in the center display unit that can cause the screen to go blank when shifting into reverse, preventing the backup camera image from appearing. The repair involves replacing the center display unit at a dealership.

Buying a Used Forward Camera: What to Check

Purchasing a used OEM forward camera can save you hundreds of dollars, but it comes with a critical requirement. This is not a simple plug-and-play part.

• Match the Part Number Exactly: The most critical step is to ensure the part number on the used camera matches your original part. Different part numbers may exist for different trim levels or feature sets. Using the wrong camera will result in calibration failure.
• Inspect the Lens: Carefully inspect the camera's lens for any scratches, chips, or haziness. Even minor damage to the lens can prevent the camera from seeing the road clearly and cause calibration to fail.
• Check the Connector: Ensure the electrical connector and its pins are clean, straight, and free of any corrosion or damage.
• Budget for Calibration: The cost of calibration is separate from the part itself. Before buying a used camera, get a quote from an Acura dealer or a qualified auto glass/ADAS specialty shop for the calibration procedure. This can cost anywhere from $300 to over $600.

Replacement and Calibration Procedure

Physical Installation (DIY Feasible)

Physically swapping the camera is straightforward and can be done by a DIYer with basic tools in under 30 minutes.

1. Disconnect the battery.
2. Carefully pry off the plastic covers behind the rearview mirror. They are typically held on by clips.
3. Unplug the electrical connector from the camera module.
4. Release the tab holding the camera to its bracket on the windshield and slide it out.
5. Install the new (used) camera, reconnect the electrical plug, and reinstall the plastic covers.

Camera Calibration (Professional Required)

This is the most critical part of the job and cannot be done at home. The procedure electronically aims the camera and teaches it to recognize its position on the vehicle relative to the road.

• Who can do it: An Acura dealership or an independent repair/glass shop that has invested in specialized ADAS calibration equipment.
• The Process: Calibration involves two parts. First is a 'static' calibration, where the technician places specific patterned targets at precise, measured distances in front of the vehicle. A scan tool is used to command the camera to learn the targets. 🎬 Watch: How professional ADAS calibration targets are used Second, a 'dynamic' calibration may be required, which involves driving the vehicle on well-marked roads to finalize the aiming process.
