I've been driving for many years and have encountered the blue battery light on the dashboard. This is usually a warning signal from the charging system, indicating that the alternator may not be working and the battery isn't charging. If you ignore this light, the battery will quickly drain, causing the car to stall on the road, which is especially dangerous at night. I remember once when the light came on during a business trip, I immediately checked if the alternator belt was loose or broken, and also tested the battery voltage to see if it was normal. I suggest you first find a safe place to park and avoid driving for extended periods. It's best to go to a professional repair shop as soon as possible to check the alternator, voltage regulator, or battery cables. Regular maintenance checks on these components can prevent similar issues. Battery life typically lasts a few years before needing replacement, so don't wait until it fails to take action.

Why does an automatic transmission car stall when braking?

Automatic transmission cars stalling when braking is not a malfunction but rather the engine's auto start-stop function. If the vehicle does not have an auto start-stop function, the possible reason could be braking too abruptly. Although pressing the brake causes the transmission to downshift automatically, excessively rapid braking can exceed the transmission's reaction speed, leading to the car stalling. Additional Information: Principle of Intelligent Start-Stop Function: High-end vehicles are equipped with an intelligent engine start-stop function. When the vehicle is in a stopped state (not in park), the engine will pause operation (instead of maintaining traditional idle speed). During this pause, the engine's lubricating oil continues to circulate, ensuring internal lubrication. Upon releasing the brake pedal, the engine will restart. Automatic Transmission: As the name suggests, an automatic transmission does not require the driver to manually shift gears. The vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Typically, automatic transmission cars have six gear positions, arranged from top to bottom as P, R, N, D, S, and L.
