On March 31, 2026, Baidu's Apollo Go robotaxi service in Wuhan experienced a widespread system failure, causing numerous autonomous vehicles to stop abruptly in live traffic, including on highways. Passengers were stranded inside the vehicles for extended periods, and the failure led to multiple traffic collisions, including one involving an SUV traveling at 40 mph. Local authorities and the company confirmed the incident, citing a system malfunction.
Baidu's Apollo Go robotaxi service in Wuhan experienced a reported system failure that left multiple vehicles stopped in live traffic, including on elevated roads, and stranded some passengers until police and company personnel responded. At least 100 vehicles were reportedly affected. Police said no injuries were reported.

A widespread system failure in Baidu's Apollo Go autonomous robotaxi fleet in Wuhan caused multiple vehicles to freeze in live traffic, leading to localized disruptions and minor collisions. The incident represents a minor physical security and infrastructure concern regarding the robustness of autonomous transport systems, but carries negligible broader national security implications.
The Baidu Apollo Go vehicles are fully autonomous robotaxis operating on public roads without human drivers, making real-time driving decisions based on environmental inputs.
High Risk: The system is an AI used in critical infrastructure (specifically, traffic management and autonomous transport/robotaxis on public highways).
The AI system's primary function is to operate self-driving robotaxis autonomously on public roads.
The reports from multiple sources consistently describe the timeline, location, and consequences of the system failure. While the exact technical root cause is only briefly attributed to a 'system malfunction' or 'network reasons', the physical events and resulting harms are well-documented.
None. The event is clearly a technical failure of an autonomous vehicle fleet.
Technology
Vehicle System Malfunction
A sudden system malfunction caused the autonomous vehicles to freeze in traffic.
Network Connectivity Failure
Customer service reported the driving system anomaly was due to network issues.
SOS Button Malfunction
Passengers reported the in-car SOS button was completely unavailable.
Human Factors
Passenger Panic and Confusion
Passengers were trapped inside frozen vehicles with misleading instructions.
Delayed Driver Reactions
Other drivers on the road could not react fast enough to avoid stopped taxis.
Process and Methods
Inadequate Emergency Response
Baidu customer support failed to dispatch help or provide clear information.
Unresponsive Support Channels
Phone support took 30 minutes to reach and SOS buttons did not work.
Misleading In-Car Instructions
Screens instructed passengers to wait 5 minutes, but help never arrived.
Management
Poor Incident Management
Baidu lacked effective procedures to quickly resolve widespread vehicle freezes.
Inadequate Support Staffing
No company representatives arrived to assist passengers trapped over an hour.
Regulatory Environment
Aggressive Public Road Testing
Wuhan aggressively permitted fully autonomous vehicles on busy highways.
AI system involved
Identified by automated extraction; can differ from the alleged developers above.
