The National Highway Transportation Safety Administration is adding more pressure onto Tesla in regard to the "phantom braking" issue.
According to Reuters, NHTSA is requesting a response be made by Tesla by June 20. NHTSA opened its investigation on this issue back in February, as FenderBender previously reported.
NHTSA has reportedly received 758 reports regarding this brake issue. The "phantom braking" is tied to when the vehicle's Autopilot program is engaged and results in the vehicle suddenly slowing down.
According to Reuters, a 2021 Tesla Model Y owner told NHTSA:
"The car braked hard and decelerated from 80 mph to 69 mph in less than a second. The braking was so violent, my head snapped forward, and I almost lost control of the car."
The investigation covers over 400,000 Teslas, specifically the 2021 and 2022 Model 3 and Model Y. Owners have told Tesla about the issue, but Tesla has allegedly dismissed the problem and called the braking system normal.
Tesla has not yet commented on the NHTSA request for response by June 20.
