When a BCI warning appears on the QX60, taking prompt action can help determine if the issue is minor or requires professional service. Many malfunctions stem from temporary sensor blockages, low battery voltage, or minor software glitches. Acting quickly can prevent further complications and maintain driver-assist functions.
Quick Fix Steps
Disconnect trailers: BCI is disabled during towing. Remove all hitches or wiring. Restart vehicle: Park safely, turn off the engine, wait one minute, then restart. Check battery: Ensure voltage is above 12.2V when off and 13.5–14.7V while running.
If the warning persists after these quick steps, you can move on to more detailed at-home troubleshooting to identify and address potential sensor, battery, or obstruction issues.
At-Home Troubleshooting
Clean sensors: Use soap, water, and a microfiber cloth. Avoid high-pressure sprays. Remove obstructions: Check for trailers, bike racks, or bumper accessories blocking sensors. Battery reset: With the engine off and the key out, disconnect the negative terminal for 5–10 minutes, then reconnect. Verify system: Restart the vehicle and check if warning lights remain.
Avoid using generic OBD-II scanners, disassembling sensors, or replacing modules yourself. If warnings continue, escalate to an authorized INFINITI service center to keep the QX60’s driver-assist features fully functional and safe.
What is Backup Collision Intervention (BCI) on the QX60, and Why Does It Malfunction?
Backup Collision Intervention on the QX60 is a safety system designed to prevent collisions while reversing. It uses rear radar sensors and the vehicle’s control modules to detect obstacles and automatically apply brakes if a collision is likely.

BCI Functions and Possible Issues
Detect obstacles behind the vehicle: Sensors blocked by dirt, stickers, or snow. Apply automatic braking: Software glitches or module errors. Alert driver: Low battery or loose connections. Coordinate with driver-assist features: Misalignment after bumper repairs.
Proper attention to sensor cleanliness, secure connections, and current software ensures reliable operation. Minor issues can often be resolved at home, while recurring problems should be handled professionally.
Which Issues Most Often Trigger an INFINITI QX60 Backup Collision Intervention Issue?
Several common factors can trigger an INFINITI QX60 backup collision intervention issue. Recognizing these helps owners take preventive action and know when professional service is necessary.
Common Triggers
Sensor blockage: Dirt, mud, snow, stickers, or road debris covering sensors. Low battery: Voltage below recommended levels affects system reliability. Wiring problems: Loose connections or corrosion in the rear harnesses. Post-repair misalignment: Bumper or sensor repositioning after collision repairs. Accessories interference: Trailers, bike racks, or bumper attachments blocking sensors.
Environmental factors, such as rain or humidity in Tallahassee or nearby areas, can worsen sensor blockage. Identifying these triggers helps maintain proper QX60 driver-assist function and ensures BCI works as intended.
Signs You Should Seek Professional Service for a QX60 BCI Malfunction
Knowing when to escalate BCI system troubleshooting in 2025 is essential for safety and system reliability. Some issues cannot be resolved at home and require professional attention.
Signs to Seek Service
