Tesla has over 750 complaints of cars braking for no reason in U.S.

Over 750 Tesla owners have complained to U.S. safety regulators of cars suddenly stopping on roads for no reason.

The National Highway Traffic Safety Administration (NHTSA) revealed the number in a information request posted on the agency’s website Friday.

The 14-page letter asks the company for all consumer and field reports it has received about false braking, and reports of crashes, injuries, deaths and property damage claims.

It also asks whether the company’s “Full Self Driving” and automatic emergency braking systems were active at the time of any incident.

Many owners said they feared a rear-end crash on a freeway.

The agency began investigations after getting 354 complaints about phantom braking in Tesla’s Models 3 and Y last February.

The investigation covers an estimated 416,000 vehicles from the 2021 and 2022 model years. In February, the agency said it had no reports of crashes or injuries.

Tesla has a deadline of June 20 to respond to the information request, however, the company is able to ask for an extension.

It’s the fourth formal investigation of the automaker in the past three years, and NHTSA is supervising 23 Tesla recalls since January of 2021.
