Top 5 Reasons Car Engine Stops Suddenly

It’s not like the typical movie scene, where only the old cars give up in the middle of nowhere. Relatively newer cars can also fall prey to this problem. Why? Because there are certain serious reasons why a car engine stops suddenly.

It is a known fact that the less you care for your car, the more troubles it is going to create for you. One of the major dreaded car troubles is the sudden stopping of the engine, and it can make the car stops while driving. 

Top 5 Reasons Car Engine Stops Suddenly

Before you head to find out the reasons why a car engine stops suddenly, you must realize that this sudden stopping of the engine can be highly dangerous. 

If your car engine cuts out abruptly, you are likely to lose control. Not only can it be dangerous but also fatal if you are driving at a very high speed.

1. Overheated Engine

This is one of the most common reasons why a car suddenly stops. As the fuel burns, the chemical energy is changed into heat energy. 

The engine further changes it into mechanical energy that moves the car parts. In cases when this heat in the engine bay goes beyond the normal range, it starts melting the piston. As it sounds, it is not a good sign.

Eventually, if the temperature keeps rising, it is bound to stop the engine. There are several reasons that contribute to engine overheating.

2. Choked Catalytic Converter

The catalytic converter is a vital part of the exhaust system. It plays a major role in keeping the exhaust clear. 

If there are more impurities in the fuel than the converter can handle, it gets choked and stops working, so ‘car suddenly stops‘ situation appears.

The result is that the exhaust backs up in the pipe and the engine has to work harder. Ultimately, the engine gets overworked, resulting in stalling. 

This kind of stalling is usually preceded by vibration and rattling in the engine.

3. Inadequate Transmission Fluid

An inadequate level of transmission fluid can also be one of the reasons a car engine stops suddenly. This level differs from make to make and model to model. 

So, refer to your car’s owner’s manual. Follow the maintenance notices according to the manual to keep the fluid level right.

4. Electrical Issues in Ignition/Computer

There could also be electrical issues with the ignition or the computer. Signals could be getting crossed, causing the engine to shut down. 

In such cases, you are likely to see the “check engine” light. If you continue driving despite the light, it will create chances for car suddenly stops. 

This could be more so with the case of sophisticated modern cars and hybrid cars.

5. Loose Engine Bolts

Though it doesn’t happen that often, it does happen sometimes. Improper maintenance of the engine can lead to many problems. 

If the bolts of the engine are loosely screwed, the engine will start vibrating and ultimately start malfunctioning. 

The wear and tear that the engine goes through while driving, can cause the loose screws to ultimately come off. The engine is sure to self-destruct and stop in that case.
