Tesla Recalls 2.7 Million Vehicles in China to Upgrade Driver Monitoring Systems

Tesla is deploying an over-the-air software update to 2.74 million Model 3 and Model Y vehicles in China to fundamentally alter how it monitors driver attention. The recall shifts the primary safety check for the company's assisted-driving system from the steering wheel to the interior cabin camera.[1]

The sweeping action was mandated by China's State Administration for Market Regulation (SAMR). The regulator ruled that Tesla's existing mechanism for Level 2 "combination driving assistance" was insufficient to warn drivers when their gaze left the road, increasing the risk of collisions.[1]

For years, the automotive industry standard for driver monitoring relied on steering-wheel torque sensors. These systems measure physical resistance, requiring the driver to periodically apply a slight turning force to the wheel to prove they are engaged with the vehicle.[2][3]

However, torque sensors cannot verify cognitive or visual attention. A driver can keep a hand resting on the wheel while looking down at a phone or even sleeping. In China, some drivers actively bypassed the system by attaching aftermarket weights to the steering wheel, tricking the sensor into registering continuous physical contact while they rode hands-free.[6]

To close this loophole, the SAMR recall forces Tesla to activate its interior cabin camera across the Chinese fleet. The camera, mounted above the rearview mirror, uses machine learning algorithms to track eye gaze and head position. If the system detects that the driver is not looking at the road, it issues escalating audio and visual alerts.[3][4][5]

While cameras measure visual attention directly, they introduce entirely new spoofing vulnerabilities. Shortly after Tesla began rolling out its supervised camera monitoring, Chinese drivers were filmed using $20 plastic doll heads mounted near the rearview mirror to fool the eye-tracking software into registering an attentive human face.

The transition also carries significant privacy implications. Tesla had previously resisted activating cabin cameras in the Chinese market, citing data security and local privacy laws. The SAMR mandate effectively forces a fleet-wide adoption of biometric surveillance, reflecting a global regulatory consensus that direct visual monitoring is necessary for advanced driver-assistance systems.[2][6]

The driver-monitoring update was one of two massive regulatory actions Tesla faced in China on the same day. A separate, overlapping recall covered 2.98 million vehicles—including imported Model S and Model X units—to address emergency mechanical door releases that regulators deemed too difficult to locate after a severe crash and power failure.[1]

Unlike traditional automotive recalls that require owners to schedule dealership visits for physical repairs, both of Tesla's fixes are being deployed remotely. The ability to resolve millions of regulatory safety violations overnight via software updates highlights how connected architecture is reshaping the mechanics of automotive compliance.[1][6]
