Why does the Buick Excelle stall while driving?

[KimberlyFitz]

Here are the reasons why the Buick Excelle may suddenly stall while driving: 1. Electrical circuit failure: Stalling due to low-voltage power interruption during driving, mainly check the ignition and starter switches as well as the fuse box. 2. Low-voltage circuit short circuit causing stalling: In this case, the stalling occurs intermittently; inspect the low-voltage circuits. 3. Component failure: This issue is usually related to the ignition coil, capacitor, or electronic ignition module. The car may start initially, then stall after a while, restart, and stall again. 4. Fuel system failure: Damage to the fuel pump, fuel line rupture, clogged fuel inlet, or empty fuel tank. However, the car can usually be restarted in these situations. 5. Ignition system: Problems with the engine overheating protection system can also cause stalling.
