The owner of a BYD Atto 3, who shared footage of his EV suddenly performing an emergency brake while on the highway, has revealed what caused the incident.
The Malaysian driver was heading from Melaka to Penang when his BYD Atto 3 suddenly came to an abrupt stop without warning.
The car was travelling along the fast lane of the Cheras-Kajang highway at the time.
There was plenty of speculation about what caused the incident, but BYD has since revealed the true cause.

What caused the BYD Atto 3 to brake without warning?
BYD launched the Atto 3 into the Chinese market, where it is sold as the BYD Yuan Plus, back in 2022.
It has since been rolled out to numerous markets, including Malaysia, New Zealand, Germany, and Japan.
Back in May, a Malaysian driver shared a post on Facebook detailing a scary experience he had in his BYD Atto 3 after it suddenly performed an emergency braking on a busy highway.
The driver said he made several attempts to get the car going again, but that it wouldn’t move, and the screen displayed a ‘Power System Failure’ notification.
He went on to say that as he was unable to move the car, he almost caused an accident.
With the car not going anywhere, the highway patrol was called out to place cones around it.
A tow truck arrived around an hour later, but the car couldn’t be towed as the wheels were locked, despite the car being in neutral.
Eventually, the car had to be placed onto wheel dollies and loaded onto a flatbed truck.
The EV was taken away to be investigated by BYD, with many folks online speculating the problem may have been caused by the 12V battery.
However, while the initial assessment seemed to agree that the 12V battery was the issue, further investigations from the BYD service centre found that a faulty sensor located at the driver’s door was the actual cause.
In an update, the driver said the broken sensor triggered the Atto 3’s safety sequence, causing it to perform an emergency brake.
The car has a five-star safety rating
Thankfully, incidents like the one above are rare.
In the 2022 Euro NCAP testing, the Atto 3 was awarded five stars, earning a huge 91 percent for Adult Occupant Safety and 89 percent for Child Occupant.
Its Safety Assist was given 74 percent, while the Vulnerable Road User score was 69 percent.
