Why can't BYD's one-button start stop the engine?

[PeterFitz]

Generally, if BYD's one-button start cannot stop the engine, simply shift to P gear, restart the engine, and then stop it again to resolve the issue. It is recommended to check the vehicle's user manual, which usually provides explanations. If the problem persists, you can only contact a 4S store for professional assistance. Different models, key detection failure, or battery issues can all cause BYD's one-button start to fail in stopping the engine. Different models have different operations: For example, driving a colleague's car of a different model may require different operations. Some models require a long press to stop the engine, some require two clicks (one to stop the engine and another to cut off all power), while others only need a single click to stop the engine. Key detection failure: Sometimes, strong nearby magnetic fields can cause interference, preventing the key from being detected. Solution: Align the key with the one-button start. Battery issues: Either the battery is dead or its voltage is below 12V. In this case, a long press can stop the engine.
