Reasons Why Your Car Is Stopping Suddenly

  1. Engine Overheating
  2. Low Levels of Transmission Fluid
  3. Problem With Alternator
  4. Faulty Fuel System

There could be many other reasons why your car is suddenly stopping, we are discussing the most common reasons.

1. Engine Overheating

Engine overheating can cause your car to suddenly stop. This is by far the most common reason for that. If your engine overheats this causes the whole system and the flow of work of spare parts associated with it. 


Moreover, It increases load over the engine which in turn stops the car from operating.


The most common reasons for engine overheating are insufficient coolant, faulty radiator, low engine oil, low-quality engine oil, clogged coolant hose, and many other problems.

2. Low Levels of Transmission Fluid

Transmission Fluid Check

The transmission fluid of your car is responsible for maintaining and lubricating the transmission system of your car. The transmission system of your car includes different gears and clutches.

When there is a reduction in the transmission fluids of your car, this creates problems in the system, there is more friction in the transmission system, this causes the car to stop suddenly.

The transmission fluid is not supposed to be changed as frequently as the engine oil. But it has to be checked at a regular schedule for your car service.

3. Problem with Alternator

Car Alternator problem

The Alternator of your car generates electricity as you drive. This electricity is used for electric-based appliances in your car like your headlight, Air conditioning system, Speakers of your car, and simultaneously recharging the battery and many other such electrical needs. 


Most importantly, the electricity generated by the alternator is used in generating the sparks in the spark plug. This runs the combustion engine properly. 


So, When there is any problem with the alternator of your car, it directly affects the functioning of spark plugs. No spark ignition stops the combustion process of the engine.


Improper functioning of the alternator is one of the major reasons why your car is suddenly stopping.

4. Faulty Fuel System

The fuel system ensures a proper supply of fuel to keep your car running. This includes the fuel pump which is responsible to provide the correct amount of fuel supply to the engine. If there is less supply of fuel, your car will immediately stop.


Along with that, there could be problems with the fuel filter. The fuel filter ensures the cleanliness of the fuel supplied to the engine. If the fuel filter is clogged, there will be a decrease in the smoothness of fuel supply and hence the fuel reaching the engine would be less. A clogged fuel filter is a reason for your car to stop immediately.


And, the most obvious reason for your car suddenly stopping could be the lack of fuel in your car. Please keep monitoring the fuel gauge in your dashboard. If the fuel is low, it will suddenly stop.

5. Problematic Catalytic Converter

Unlike other components mentioned in this blog post, a Catalytic converter comes in the exhaust system of your car. 


The Catalytic converter is responsible for cleaning the exhaust fumes. It reduces the harmful gasses like carbon monoxide, nitrogen dioxide, hydrocarbons, nitric oxide, etc, and chemical reactions change these gasses into carbon dioxide and water vapors.


When there are too many impurities and the cleaning of the catalytic converter is pending for a long time. There is clogging in the catalytic converter. This result is overload to the engine and the complete system.


Clogged or problematic Catalytic Converters can cause your car to suddenly stop.

Can low car battery cause sudden shut down of your car?

No. The low battery will not shut down a running engine or a running car. Because the car alternator generates the required electricity in a running car and this electricity is supplied to the car.


However, If your car battery is low, you could experience problems in starting your car.

Can low engine oil cause sudden shut down of your car?

In a normal scenario, low engine oil doesn’t necessarily cause the sudden shut down of your car. However, Low engine oil causes overheating and other engine problems which could result in the shut down of the car after a particular time period.


In recently launched cars, there are sensors that detect low engine oil and for safety reasons, the car automatically shuts down the car, in case of low engine oil.


We highly recommend you to have high-quality engine oil for your car, so that these problems do not occur.
