Your car has a complex mechanism of injecting fuel at high pressure into each cylinder thousands of times per minute. When this fan seizes or becomes faulty, your car may overheat at low speeds or when in heavy traffic. Even when your car is stationary, the engine management system should turn on the fan situated just in front of your radiator to ensure that your engine can remain cool when the car is stationary. In this case, the digital engine management system should turn your engine off to prevent permanent damage to the pistons, and this may be the cause of your car dying unexpectedly. When there is a leak in this system, the thermostat becomes faulty or the water pump fails, and the engine will no longer be cooled properly. The cool water is then circulated around the engine to keep it cool as the combustion process produces extremely high temperatures in and around your car’s engine. Your car most probably has a liquid cooled system which relies on water being cooled in your car’s radiator by the air stream as your car moves. After a few days, your battery will run completely flat, and it will no longer be able to provide the power that the car needs to start the engine and keep it running. If the alternator becomes faulty, it will cease to charge your battery.

Your alternator is faultyįollowing on from above, your alternator is the component that charges your battery. When a connection to the battery is faulty, the alternator can no longer charge the battery, and when there is insufficient power being generated by the alternator while your car is running, it will cause your vehicle to cut out unexpectedly. This may happen due to vibration while driving, hitting a bump in the road, or through corrosion of the cable or terminal joint. One of the most common issues here is that the terminal on one of the sockets on your battery has become loose, and is no longer making a good connection to the battery. In the old days, your car may have continued to run without the battery connected, but most modern vehicles today have many complex systems that require power to keep the vehicle running. Your battery is faultyĪ car’s battery is essential to keep the vehicle running. If you have filled up recently, then this may be an indication that your fuel sensor has become faulty. Try remember when you last filled up the tank, and how far you have been driving since then. If it is, there is still the possibility that your fuel sensor has become faulty, meaning that you have actually run out of fuel, but your car is still telling you that there is petrol in the tank. Check the fuel gauge on your vehicle’s dashboard, and make sure that it is above the “E” mark. Yes, although the most obvious one, this is the most common reason that causes vehicles to cut out unexpectedly.

Reasons why your car may turn off while driving You have run out of fuel So, if you’d prefer to not be stuck on the side of the road helplessly looking under the hood of your car, read on. However, there are some common causes, and some of those are very simple to fix. With many complex systems all working together to keep your car running, it can be difficult to pinpoint which system is causing your car to turn off while you are driving.
