One of the most confusing and dangerous situations to be in is if your car engine dies down suddenly while you are driving. The reason why the engine behaves in this way is when the required power to drive the engine is suddenly cut off or fails.
A failing battery or a drop in the transmission fuel, an overheated engine, or a malfunctioning component such as the ignition switch or sensors, are some of the most common reasons behind the engine stopping while driving.
What should you do if your car engine stops while driving?
If this happens to you, don’t panic. The best thing to do if you find yourself in this situation is to move off the road while there is momentum in the wheels.
Also, keep in mind that a failing battery or engine overheating is not limited to old cars. So even if you are driving a new car, there are several reasons your engine could suddenly stop. Here are some of the most common reasons why this happens:
The job of the alternator is to convert the mechanical power from the rotating components of the car to electrical energy which in turn powers several other functions of your car.
Any issues with the alternator could lead to your car engine shutting down completely. Tell-tale signs of alternator issues include:
- If your car battery dies without any reason, it could indicate alternator issues.
- Have your alternator checked before replacing the battery because if the fault is with the alternator, the new battery will die just as quickly.
- If the warning lights on your dashboard start flashing, it could be due to electrical or mechanical issues. Have your alternator checked up.
- Dimming headlights is again an indication that your car could be facing alternator issues.
Low Transmission Fluid
If the transmission fluid level in the transmission is not maintained at the required levels, it could lead to engine failure.
- Check your owner’s manual to find out the level of transmission fluid for your car since different makes and models have different transmission fuel requirements.
- If you find the transmission fluid levels are low, top it up. If you can’t do this, any auto service repair shop will be able to do it for you.
- If your transmission fuel level keeps dropping, you might have a leakage issue. It is best to have the car checked out as quickly as possible.
Engine Overheating Issues
This is a very common reason for the engine of a car to suddenly stop while driving.
- Keep in mind the internal running of the mechanical and electrical components creates a lot of friction and heat.
- To ensure overheating does not impact the performance of the car; engine coolants are used which help in maintaining the temperatures within a normal range.
- If this range is breached, it can cause the piston to melt, resulting in the engine shutting down while driving.
Problems with the Computer or the Ignition System
If there are issues with the electrical components of the car, the engine will not be able to receive the proper electrical signals.
- If you notice the check engine warning light flashing on your dashboard, it could indicate a problem with the car computer or the ignition system.
- Most engine problems get aggravated because the driver ignores the check engine warning light.
- Timely repairs can save you from bigger engine problems in the future so never ignore the warning lights!
Failing Catalytic Converter
The catalytic converter in your car is responsible for clearing out the exhaust. However, if the fuel is contaminated or has a lot of impurities, it can lead to the convertor failing.
- When this happens, the converter won’t be able to clear out the exhaust.
- The tailpipe will then hold more exhaust which in turn places a lot of pressure on the engine.
- If the engine reaches a certain tipping point, it will simply shut down.
Proper Maintenance is Vital
In addition to being extremely risky, the shutting down of your car engine while driving can be very frustrating. Routine servicing is one of the best ways to ensure everything is working fine with your car. You can avoid these costs by having a professional mechanic service the car at regular intervals.
