Apart from a flat tire, the worst thing that can happen to your car while driving is that its battery goes dead. Many wonder if their car battery can even die when driving.
There are various reasons why a car battery can die and stop while driving, and as a driver or owner of the car, you should be aware of the reasons to fix them. This is because you may not get a car mechanic in the middle of the road, and hence, you have to understand the problem and know the method to fix the issue to bring your car to life again.
Reasons Why The Car Battery Drains/Dies While Driving
1. Being out of Fuel
One of the primary reasons your car dies while driving is when the battery is out of fuel. This is a common thing and happens to most of us. It is important to feed your car with fuel so that you will be able to restart the engine. Once you pump diesel or petrol, you will be able to go ahead with your driving. To prevent this, you need to note the slight buzzing sound while starting your car. However, it will be advisable to check the fuel gauge by a professional as there can be a false reading.
2. Alternator Problems
The battery of your car can run off even when the alternator has some issues. You will have to note that the alternator supplies additional electric power and charges the battery when the engine is running. It is very important for the electrical systems of your vehicle. Even when you happen to get a new battery, it needs proper charge by the alternator.
To make your car go, the battery and the alternator must work collectively. If you happen to see a red battery light flickering on the dashboard, it means that the alternator is sending an S.O.S. You will have to stop your car immediately and visit an auto-repairing service provider to fix the problem.
3. Problematic Ignition Switch
If there is a malfunctioning ignition switch, you will be able to face various problems. Your car will not start, and you can even not have access to radio and other appliances. It happens as a worn-down ignition switch can cause a loss of power to the engine. It is the power loss that can make the car die out while driving.
4. Something is Faulty In the Fuel Pump
Another reason that can make a car stop while driving is when there is something wrong with the fuel pump. For this, it is important to be careful while feeding your car with fuel. If by any chance you happen to pump petrol into diesel cars or diesel into petrol cars, you may face this problem. It will lead to unwanted car failures. Another reason may be if something is blocking the filter or the fuel pump. It is always advisable to get your car towed by visiting the nearest workshop. In some cases, you may even hear a slight buzzing sound while first starting your car.
5. Malfunctioning Sensors
You will have to note that the sensors can detect both physical and chemical changes in the car. However, at times the sensors can fail and give incorrect information. This can greatly impact the performance and efficiency of the vehicle. Do keep in mind that modern cars come with computers. It is one of the reasons that it can transmit wrong information.
6. A Faulty Battery
We know that a dead battery will not start. If there is a faulty or bad battery, you will not face any problem while starting. However, it may become dead while driving. One of the reasons for this is that the alternator keeps the engine system running. When the alternator does not cause more stress, there will be a risk of stalling. Keep in mind that even a (high-end) car battery can last for a maximum of 2 years. It is important to replace the car battery so that you don’t face any stalling problems.
