More than 750 Tesla drivers have complained about unexpected braking while operating the electric vehicles' partially automated driving systems.
Driving the news: The National Highway Traffic Safety Administration, which investigated the electric vehicle manufacturer's driving features, revealed the figures Friday in an information request letter to Tesla, AP reports.
The big picture: NHTSA opened the investigation into unexpected braking while Tesla vehicles were in autopilot beginning in February after receiving 354 complaints.
- The investigation spanned model years 2021 and 2022, comprising roughly 416,000 vehicles, per AP.
- It was the third probe that NHTSA opened into Tesla's driving features during a six-month period.
What to watch: NHTSA asked the automaker to respond to questions for its brake activation probe by June 20, Reuters reports.
