Why did the Buick suddenly fail to start?

[Thaddeus]

The reasons why a Buick suddenly fails to start are as follows: 1. Steering wheel lock: If the car fails to start and the key cannot be turned, it may be due to the steering wheel being locked. When parking, if the steering wheel is not straightened and remains at a slightly larger angle, the steering wheel will automatically lock as an anti-theft measure. In this case, the key may not turn, preventing ignition. 2. Battery failure: Leaving the headlights on for a long time can drain the battery, or the battery may have reached the end of its lifespan. Additionally, installing xenon headlights, high-power audio systems, DVD players, etc., can also cause vehicle circuit failures.
