Is It a Problem If the Car Doesn't Turn Off After Removing the Key?
3 Answers
If the car doesn't turn off, the key cannot be removed. Idling for extended periods can easily lead to carbon buildup in the vehicle. Below is relevant information about engine stalling: 1. Reasons for stalling: Automatic transmission models rarely experience stalling, whereas manual transmission models may stall frequently due to lower driving proficiency. However, it's not impossible for automatic transmission cars to stall, with the main cause being the use of low-quality fuel leading to engine carbon buildup and stalling. 2. Precautions: It's best to refuel at reputable, larger gas stations with higher-grade gasoline. Although more expensive, the fuel quality is superior.
I'm very familiar with this issue, as I often encountered similar situations when helping people repair cars before. If the car remains running after removing the key, it indicates there might be a problem with the ignition system, such as a faulty switch or relay malfunction. A car that won't shut off is quite dangerous—the battery will gradually drain, you might suddenly lose power while driving at night, emissions pollution will increase, and it wastes fuel while damaging the car. I recommend immediately finding a safe place to park and shut off the engine, then check the fuses or wiring connections. If that doesn't work, take it to a professional repair shop. Don't underestimate this issue—continuous operation could lead to engine overheating and damage, resulting in higher repair costs. Regular maintenance checks by a technician on the ignition system can help prevent this.
As someone who has been driving for ten years, I've had this experience too. Back then, when I pulled out the key and the car was still humming, it really made me sweat. This issue could be minor or major—it might just be a loose connection of a small part, but ignoring it could lead to increased fuel consumption. Prolonged idling can cause exhaust pollution to skyrocket and even affect health. I remember that time I quickly pulled over and turned off the engine, only to find the ignition wiring was loose. My advice is don’t hesitate—address it immediately. Check the switches or battery connections; safety comes first. Cleaning engine components during car washes helps prevent such issues.
