What are the reasons for the Buick Verano not responding when starting?

[LeJace]

Buick Verano not responding when starting may be due to reasons such as incorrect engine timing or control module failure. Below are the specific explanations: 1. Prolonged vehicle parking: The usage time of the car battery is the main cause of power loss. Typically, the lifespan of a car battery is two to three years. If it exceeds this period, the car is highly likely to experience power loss after being parked for two to three days, leading to weak starting. 2. Forgetting to turn off lights and onboard electronics: If the interior lights are left on when parking and turning off the engine, the battery may be depleted after a night, resulting in insufficient power and weak starting. 3. Forgetting to turn off the air conditioning before shutting down the engine: Most drivers are accustomed to leaving the air conditioning on or letting it start automatically when the vehicle is turned on. This causes the air conditioning system to activate automatically every time the ignition switch is turned on, directly leading to an instant high power load on the vehicle. Over time, this will cause wear and tear on the battery.
