What are the advantages and disadvantages of the auto start-stop function in cars?

The advantages and disadvantages of the auto start-stop function in cars are as follows: 1. Advantages and reasons: The principle of the auto start-stop system is to add an electric motor to the common gasoline engine. When the car is stopped and the engine is idling, the engine will completely shut off. When it is necessary to start, the electric motor quickly starts the engine by the driver stepping on the accelerator pedal, clutch, or turning the steering wheel, achieving seamless transition and thereby reducing fuel consumption during idling. 2. Disadvantages and reasons: (1) Frequent engine starts and stops can cause damage to related components such as the starter and battery. Although vehicles equipped with auto start-stop systems use enhanced starters and batteries, in actual use, their failure rates are higher than those of ordinary vehicles without auto start-stop systems. (2) The maintenance costs of enhanced starters and batteries are higher than those of ordinary starters and batteries. Additionally, due to the frequent repeated starts and stops of the engine, there is a higher demand for oil quality, further increasing maintenance costs.
I find the auto start-stop function quite practical. The advantages include helping you save on fuel costs. When I drive in the city and stop at red lights, the engine automatically shuts off, reducing fuel consumption significantly. Calculated over a month, it can save me dozens of dollars. Additionally, this feature is environmentally friendly, reducing exhaust emissions, especially in congested areas—it adds up and makes a meaningful difference. However, there are also downsides. Occasionally, there’s a slight vibration when the engine restarts, particularly in hot weather when the AC stops, causing momentary discomfort. In the long run, it puts extra strain on the battery and starter, leading to faster wear and higher maintenance costs. I’ve also noticed some instability when starting on slopes or a slight delay during rainy days. Overall, the benefits include resource savings, but it’s important to adjust based on your driving habits.
As a driver who is frequently on the road, the auto start-stop feature has both advantages and disadvantages. On the plus side, it does save fuel. I've tested it, and turning off the engine every time I stop helps me save about 5% on fuel consumption. It's also environmentally friendly, reducing pollution, which benefits everyone. On the downside, the frequent starts can be particularly annoying in traffic jams. The slight tremor when the engine restarts really disrupts the driving experience. The battery also tends to wear out faster; I had to replace mine within two or three years. Sometimes, the feature malfunctions and starts unexpectedly, which can be startling. My advice is to use it based on the weather and road conditions.
The auto start-stop system seems clever in principle, with the advantage of shutting off the engine when stopped to save fuel and reduce emissions. However, the drawbacks cannot be ignored—frequent starts and stops increase stress on components like the motor and battery, leading to higher long-term maintenance costs. In terms of comfort, the slight vibration during restart disrupts smooth driving. The benefit lies in optimizing fuel consumption, making it suitable for most daily scenarios.
