The National Highway Traffic Safety Administration (NHTSA) opened a new investigation into Tesla vehicles Thursday, this time for unexpected braking while in autopilot and driving at highway speeds.
Why it matters: It's the third investigation that NHTSA has opened into the electric vehicle manufacture's driving features in the last six months.
- It has also looked into how Tesla's autopilot function works around crash scenes and a feature that lets drivers play video games on the front-center touch screen while the car is in motion.
By the numbers: NHTSA said its Office of Defects Investigation has received 354 complaints alleging that 2021-2022 Tesla Model 3 and Model Y vehicles unexpected activate brakes while in autopilot, which allows the vehicle to brake and steer automatically within its lanes.
- "Complainants report that the rapid deceleration can occur without warning, at random, and often repeatedly in a single drive cycle," NHTSA said.
A spokesperson for Tesla did not immediately respond to a request for comment.
The big picture: Tesla recently has also had to recall and update the software for thousands of its vehicles using the Full Self-Driving (FSD) beta program because it may allow some models to conduct "rolling stops" at intersections.
- The NHTSA last year also questioned Tesla's lack of a software recall when it updated its Full Self-Driving software in late September so the system could detect flashing emergency vehicle lights in low light conditions and adjust vehicle speed in response.
- Federal law requires automakers to submit a recall when they issue an "over-the-air" update that mitigates a defect that poses an unreasonable risk to drivers.
Our thought bubble, via Axios' Joann Muller: What's new, and different, about many Tesla recalls is that they can be fixed fairly easily with a remote software update. No more making an appointment to go to the dealership. This is the future for recalls.
