Tesla recalls over two million cars due to autopilot system defects

The recall, affecting nearly every Tesla sold in the US since the introduction of Autopilot in 2015, follows a two-year investigation into crashes involving the system. These incidents occurred while Autopilot was active, prompting an extensive review by the NHTSA.

Tesla plans to roll out a software update 'over the air' to rectify the problem. This method of updating software remotely bypasses the need for vehicle owners to visit a dealership or garage. However, the NHTSA still categorises this process as a recall.

Autopilot, Tesla's advanced driver-assistance system, is designed to aid with steering, acceleration, and braking. Despite its name, the system requires continuous driver engagement and cannot operate the car independently.

The NHTSA's decision for recall stems from a flaw in Autopilot's driver monitoring system. This system is tasked with ensuring driver attentiveness, including checks like whether the driver's hands are on the wheel. From their investigation, which reviewed 956 crashes where Autopilot was alleged to be in use, the NHTSA concluded that the system's controls might be insufficient in preventing driver misuse.

In a statement, the NHTSA emphasised the potential of automated technology to enhance safety but stressed the importance of its responsible deployment. The agency also committed to continue monitoring the software post-update.

This recall follows concerns raised by a former Tesla employee, Lukasz Krupski, who questioned the readiness of both the hardware and software of Tesla's technology. In an interview with the BBC, Krupski expressed his apprehension about public road safety, considering the widespread use of these technologies.

This incident marks Tesla's second recall this year. Amidst these developments, the company recently defended Autopilot's safety record. In a post on X (formerly Twitter), Tesla refuted claims made in a Washington Post article, asserting that safety metrics were significantly better when Autopilot was engaged. Citing data, Tesla argued that automation technology contributes to the overall safety of drivers and other road users.
