3 Issues Causing Nissan Blind Spot Warning Not Working

Driving a Nissan can come with helpful safety features like blind spot warning, which alerts you when a vehicle is in your blind area. However, sometimes this feature might stop working, and it can be quite concerning.

One reason your Nissan blind spot warning may not function properly is due to sensor issues. These sensors can experience malfunction from damage or road debris. It’s important to identify and address the problem, keeping you and your passengers safe on the road.

Understanding Nissan Blind Spot Warning

How the System Works

The Nissan Blind Spot Warning (BSW) system is designed to help you stay safe and aware of vehicles in your blind spots while driving. This technology uses radar sensors mounted on the rear bumper to detect vehicles in the adjacent lanes, giving you more confidence and peace of mind on the road.

When a vehicle is detected in your blind spot area, an indicator light near the side mirror illuminates to alert you. It’s important to remember that this system is an aid and not a substitute for being attentive and checking your mirrors regularly. In some cases, the BSW may not be working properly, which can be caused by damaged or impaired sensors due to road debris or other factors.


It’s also worth noting the difference between the Blind Spot Warning (BSW) and Blind Spot Intervention (BSI) systems. While both are designed to help you detect vehicles in your blind spots, the BSI system goes a step further.

In addition to providing an alert with the indicator light, the BSI system will also activate a warning sound and will even provide subtle steering corrections if you attempt to change lanes while a vehicle is in your blind spot. This can help prevent potentially dangerous lane change collisions.

To sum it up, your Nissan’s Blind Spot Warning system is a valuable tool for increasing your safety on the road. Ensure that the system is functioning properly and rely on your own attentiveness as well to keep you and your passengers safe.

Common Issues and Solutions

Dirty or Obstructed Sensors

One of the most common reasons for your Nissan blind spot warning system to malfunction is dirty or obstructed sensors. These sensors are usually mounted on the corners of the bumper and can easily get compromised by dirt, mud, or debris. To fix this issue, carefully clean the sensors with a soft cloth or brush, being sure not to scratch or damage them. Regularly cleaning the sensors can help maintain the system’s accuracy and avoid any warning lights on your dashboard.

Camera and Radar Issues

The blind spot warning system relies on cameras and radar to detect vehicles in your blind spot area. If the camera or radar system malfunctions, your blind spot warning may not work properly. This can be due to a variety of factors, such as misaligned cameras, damaged radar components, or even software glitches. In such cases, it is best to consult a Nissan technician to diagnose and fix the problem. They can assess the system, identify any issues, and recommend the necessary repairs or updates.

Weather-Related Issues

Weather conditions can also impact the performance of your Nissan’s blind spot warning system. Heavy rain, snow, or fog may interfere with the sensors and cause them to trigger false alarms or fail to detect vehicles in your blind spot. To prevent this, make sure you regularly clean your sensors after driving in poor weather conditions and keep the camera lens free of moisture and dirt. If the issue persists, consider having a professional inspect your vehicle’s blind spot warning system for any potential problems that may be related to weather conditions.

By maintaining and promptly addressing potential issues with your Nissan’s blind spot warning system, you can ensure it functions properly and helps to keep you safe on the road.

Location and Replacement

Sensor Locations

The Nissan Blind Spot Warning system uses sensors located on the corners of your vehicle’s bumper to detect objects in your blind spots. These sensors, also known as Side Radar sensors, transmit radar signals to provide you with an alert when another vehicle or object is in a hazardous position. In some Nissan models, the system may also have sensors incorporated into the rear view mirror.

Replacement Costs

If your Nissan Blind Spot Warning system is not working, it might be time to replace the sensors. Whether the sensors suffer damage from road debris, or they malfunction due to wear and tear, the timely replacement of these parts is essential for your safety. The cost to replace the sensor can vary depending on the specific Nissan model you own and the labor fees in your area.

Here’s a rough estimate of the replacement costs you can expect:

  • Sensor price: $100 – $300 per piece
  • Labor cost: $50 – $150
  • Total cost: $150 – $450 per sensor

Keep in mind that these prices are approximate and will depend on your vehicle model and location. It’s always wise to consult with your local Nissan dealership or an authorized service center to get an accurate quote for your specific situation.

By locating and replacing the malfunctioning parts of your Nissan Blind Spot Warning system, you can ensure that you maintain optimal safety and convenience while driving. Remember, a friendly technician is always there to help you evaluate the best course of action for your vehicle’s specific needs.


In summary, if you’re experiencing issues with your Nissan’s blind spot warning system, it could be due to a malfunctioning sensor. Don’t worry, as this is a relatively common issue that can be resolved at your local dealership. Remember to drive safe and always make use of your vehicle’s safety features to protect yourself and others on the road. Stay alert and happy driving!
