What are the disadvantages of auto start-stop?

[Sue]

The disadvantages of auto start-stop are: 1. When temporarily stopping on a slope, the auto start-stop system activates slowly, making it easy for the vehicle to slide when releasing the brake, which can lead to dangerous situations; 2. In vehicles with auto start-stop systems, when the engine shuts off, the air conditioning only blows air without cooling, affecting passenger comfort; 3. If the vehicle stops during water wading and the engine shuts off, the sudden reduction in exhaust pressure can easily cause water to flow back from the exhaust pipe into the engine, preventing the engine from restarting. Auto start-stop is a system that automatically shuts off the engine when the vehicle temporarily stops during driving (e.g., at a red light) and automatically restarts the engine when it's time to move forward.
