Why does the Honda XRV automatic transmission stall when braking?

[OKing]

Honda XRV automatic transmission stalling when braking may be due to the activation of the auto start-stop system. Below are the specific reasons: Principle of auto start-stop stalling: The auto start-stop system is essentially a system that controls the engine's shutdown or ignition. Its core function is to automatically control the engine's shutdown or ignition based on vehicle speed and stopping time during driving, aiming to minimize fuel consumption and emissions during idling. It is primarily suitable for urban traffic situations such as waiting for traffic lights or being stuck in traffic. After the engine shuts down, the power supply can still replace the belt pulley to provide operating power for the engine cooling fan and the car's air conditioning system. Features of auto start-stop: The auto start-stop system has many advantages, such as reducing fuel consumption during idling, thereby saving fuel. In urban traffic situations like waiting for traffic lights or being stuck in traffic, it can significantly reduce the engine's idling time. However, frequent engine starts and stops can cause damage to related components such as the starter and battery. Additionally, due to the frequent repeated starts and stops of the engine, there is a higher demand for oil quality, which further increases maintenance costs.
