Why Did My Blind Spot Monitor Stop Working?
The failure of a Blind Spot Monitor (BSM) in an Acura MDX can be attributed to several factors, each disrupting the system’s ability to alert you to vehicles in your blind spot.
-
Sensor Blockage or Damage
The BSM relies on sensors typically located on the rear bumper or side mirrors. Dirt, debris, or snow can obstruct the sensors, while accidents or wear and tear can damage them, leading to malfunctions.
-
Electrical Issues
Faulty wiring or a drained battery can prevent the BSM from receiving the power it needs to operate correctly.
-
Software Glitches
Like any computerized system, the BSM software can experience glitches. These can often be resolved with a system reset or an update at a dealership.
-
Misalignment
If the sensors become misaligned, perhaps due to a minor collision or driving over a pothole, they may fail to detect vehicles correctly.
-
Aftermarket Accessories
Sometimes, aftermarket accessories like window tints or additional lights can interfere with sensor operation.
-
Wear and Tear
Over time, the sensors can suffer from general wear and tear, which can degrade their performance.

How Do You Turn On The Blind Spot Monitor On An Acura Mdx?
Turning on the Blind Spot Monitor (BSM) on an Acura MDX is a straightforward process. Here’s how you can activate it:
Start the Vehicle: Ensure your Acura MDX is started and the transmission is in Drive (D) or Sport (S).
Press the Safety Support Switch: This switch is usually located on the vehicle’s dashboard.
Select the BSM Symbol: Use the right selector wheel on the steering wheel to scroll to the BSM symbol.
Activate the System: Push the selector wheel to activate the BSM. You’ll know it’s on when the symbol illuminates green and a checkmark appears.
What Is The Blind Spot Warning On The Acura MDX?
The Blind Spot Warning, or Blind Spot Information System (BSI), on the Acura MDX, is a safety feature designed to alert drivers to vehicles in their blind spot areas. Here’s a detailed breakdown of how it works and its components:
-
Functionality
The BSI system uses radar sensors located under the rear bumper corners to detect vehicles in specified alert zones adjacent to your vehicle. These zones are the areas that are not easily visible using the side mirrors, commonly referred to as “blind spots.”
-
Alert Zones
The system has a range that extends approximately 10 feet (3 meters) from the rear bumper and about 1.6 feet (0.5 meters) to the sides. When a vehicle enters these zones, particularly when it approaches from behind to overtake, the system is triggered.
-
Indicators
The Acura MDX features BSI alert indicators located near the pillar on both sides of the vehicle. These indicators light up to inform the driver that a vehicle is in the blind spot area.
-
Alerts
The indicator lights up when a vehicle enters the alert zone from behind with a speed difference of no more than 31 mph (50 km/h) relative to your vehicle.
The indicator blinks and a beeper sounds when you engage the turn signal in the direction of the detected vehicle, signaling an intention to change lanes.
-
Safety Reminder
While the BSI provides valuable assistance, it’s important to remember that it has limitations. Drivers should not rely solely on the BSI when changing lanes. Always look in your mirrors, to either side of your vehicle, and behind you for other vehicles before changing lanes.
What Is The Problem Of Acura Mdx?
The Acura MDX, while known for its luxury and reliability, has had its share of problems over the years. Here’s a comprehensive look at the common issues:

How Do You Fix Blind Spots?
Fixing blind spots in your Acura MDX involves a series of checks and steps to ensure the Blind Spot Information System (BSI) is functioning correctly. Here’s a detailed guide:
Sensor Check: Begin by inspecting the BSI sensors located on the rear bumper corners for any obstructions like mud, snow, or debris. Clean them gently with a soft cloth.
Electrical Connections: Ensure that the electrical connections to the sensors are secure and not damaged. Loose or corroded connections can disrupt the system’s functionality.
System Reset: Sometimes, simply resetting the BSI system can resolve temporary glitches. You can do this through the vehicle settings menu on the infotainment system. Navigate to the ‘Driver Assist System Setup,’ select ‘Blind Spot Info,’ and then choose to turn the system off and on again.
Calibration: If the sensors are misaligned, perhaps due to a minor collision or driving over a pothole, they may require recalibration. This process is best handled by a professional at an Acura service center.
Software Update: Check if there are any software updates available for the BSI system. An outdated system may not function optimally, and an update can be performed at a dealership.
Professional Diagnostic: If the above steps don’t resolve the issue, it’s advisable to have a professional diagnostic conducted. A certified mechanic can use specialized tools to read error codes and perform a thorough check.
Component Replacement: In cases where a sensor or other part of the BSI system is faulty, replacement of the specific component may be necessary.
How Do You Test A Blind Spot Sensor?
Testing the Blind Spot Sensor on an Acura MDX involves a few steps to ensure it’s functioning correctly. Here’s a detailed explanation:
Visual Inspection: Start with a visual check of the sensors located on the rear bumper corners. Make sure there’s no damage or obstructions that could affect performance.
Clean the Sensors: If there’s dirt, debris, or residue on the sensors, clean them gently with a soft cloth and appropriate cleaning solution.
Check for Error Messages: Look at the vehicle’s dashboard for any warning lights or messages related to the Blind Spot Information System (BSI).
Engage the System: Turn on the BSI using the vehicle’s settings. The system should be active when the vehicle is in Drive (D) or Sport (S) mode and traveling between 20 mph (32 km/h) and 100 mph (160 km/h).
Perform a Test Drive: During a test drive, have a second vehicle enter the alert zone of the BSI to see if the system detects it and the indicator lights up.
Listen for Alerts: If your vehicle is equipped with an auditory alert, listen for the beeper when the system detects a vehicle in your blind spot, especially when the turn signal is engaged.
System Reset: If the system is not working as expected, try resetting it through the vehicle settings menu.
Consult the Manual: Refer to the vehicle’s owner’s manual for specific testing procedures and troubleshooting tips for the BSI system.
Professional Assistance: If you’re unable to determine the issue or the system still isn’t working, it’s best to seek professional help from an Acura service center.
