Nissan's Automatic Emergency Braking (AEB) system has been the subject of numerous consumer complaints and class-action lawsuits due to 'phantom braking' incidents. The system frequently misidentifies road features or empty space as obstacles, causing vehicles to brake abruptly or stop in dangerous traffic conditions. Nissan has acknowledged thousands of complaints and reports of minor collisions and injuries, though it has primarily addressed the issue through service bulletins rather than a full safety recall.
Nissan's Automatic Emergency Braking (AEB) feature was reported in a series of complaints for false positives and abrupt braking behaviors, endangering car occupants and traffic participants.
Domain classification, causal taxonomy, severity scores, and national security assessments were LLM-classified and may contain errors.
AI systems that fail to perform reliably or effectively under varying conditions, exposing them to errors and failures that can have significant consequences, especially in critical applications or areas that require moral reasoning.
Also classified as
The defect caused some owners to manually disable the safety feature entirely, eliminating its potential safety benefits and leading to unsafe vehicle operation.
The AEB system failed to perform robustly and reliably under varying road conditions, leading to dangerous false-positive braking events.
AI system
Due to a decision or action made by an AI system
Unintentional
Due to an unexpected outcome from pursuing a goal
Post-deployment
Occurring after the AI model has been trained and deployed
The phantom braking incidents were caused by the deployed AEB system's sensors and software unintentionally misinterpreting normal road features as obstacles.
Added categories peak at 2: Minor (Psychological Harm, Inferred)
This incident involves a commercial automotive safety defect where Nissan's Automatic Emergency Braking system engaged in phantom braking, causing minor accidents and injuries. It is a consumer safety and regulatory matter with minor physical safety implications for public roads, but carries negligible national security impact.
The AEB system operates independently to monitor the vehicle's proximity to obstacles and automatically triggers the brakes in real-time without human intervention when it detects a perceived threat.
High Risk: The system is a safety component of road vehicles, which falls under AI in critical infrastructure and safety-critical systems.
The system is designed to autonomously control vehicle braking to avoid collisions based on threat detection.
The reports provide consistent, detailed accounts of the phantom braking issue across multiple Nissan models, backed by NHTSA investigations, class-action lawsuits, and Nissan's own admissions of over 1,400 complaints.
None. The failure of the autonomous braking system is clearly documented.
Technology
Defective Sensor Modules
Sensor modules fail, causing false positives or system deactivation.
Radar Misinterpretation
Radar misinterprets normal infrastructure like bridges as obstacles.
Erratic Braking Algorithm
Algorithm triggers abrupt and forceful deceleration without obstacle.
Data Inputs
Noisy Radar Reflection
Metal surfaces and inclines return signals mistaken for obstacles.
Environmental Obstructions
Snow piles or dirt trigger false warnings and system shutdowns.
False Obstacle Detection
System detects non-existent obstacles in clear road environments.
Human Factors
Manual Feature Deactivation
Scared drivers turn off the AEB system, losing safety benefits.
Driver Surprise and Panic
Sudden braking surprises drivers, forcing dangerous evasive actions.
Dealer Misinformation
Dealerships tell consumers nothing is wrong, delaying repairs.
Process and Methods
Ineffective Service Campaigns
Using service campaigns instead of recalls limits consumer outreach.
Inadequate Pre-Market Testing
Testing failed to resolve AEB defects before mass production.
Refusal of Warranted Repairs
Dealers refuse to repair faulty systems, claiming they work as designed.
Management
Concealing Known Defects
Nissan knew of defects since 2015 but continued selling vehicles.
Prioritizing Cost over Safety
Choosing weak service campaigns over costly recalls to save money.
Misleading Marketing
Advertising systems as 'intelligent' while knowing they are defective.
Regulatory Environment
Lack of AEB Performance Standards
NHTSA has no performance standards to measure AEB success.
Absence of Mandatory Recalls
Regulators allowed service campaigns instead of enforcing a recall.
Delayed Federal Investigation
NHTSA probe was delayed despite early consumer complaints.
AI system involved
Identified by automated extraction; can differ from the alleged developers above.
