What are the Most Common Automobile Malfunctions?

Common Car Faults and Prevention Measures

As cars have become an indispensable part of our daily lives, it’s crucial for vehicle owners to be aware of the most common faults they might encounter and the preventive measures they can take. This article will cover the car faults most frequently encountered by drivers in Turkey and the points to consider to prevent these issues.

Battery Faults

The battery provides the necessary energy for the car’s electrical systems to function. Battery faults often arise from incorrect charging, prolonged disuse, or extreme temperatures.

Preventive Measures:

  • If the car will not be used for an extended period, start the engine periodically.
  • Keeping the battery clean and dry prevents the terminals from oxidizing.
  • Battery performance can decrease in winter months, so it’s especially important to check the battery before winter begins.

Axle Faults

Axles transfer power from the engine to the wheels. Excessive load, challenging road conditions, and insufficient maintenance can lead to axle faults.

Preventive Measures:

  • Pay attention to load capacity and avoid overloading.
  • Have the axle and suspension system checked at regular intervals.

Clutch Faults

The clutch plays a crucial role in controlling the transmission of engine power to the wheels. Overuse and misuse can shorten the life of the clutch.

Preventive Measures:

  • Avoid unnecessarily pressing the clutch pedal.
  • Avoid accelerating without fully releasing the clutch.

Transmission Faults

Both manual and automatic transmissions can fail over time due to wear or misuse.

Preventive Measures:

  • Regularly check the level and quality of transmission fluid.
  • Avoid sudden gear changes and use the correct gear range for driving conditions.

Engine Faults

Engine faults can occur due to incorrect fuel use, inadequate maintenance, or overheating. As the most critical component of the car, engine faults can necessitate costly repairs.

Preventive Measures:

  • Regularly change the engine oil and filter according to manufacturer recommendations.
  • Ensure the engine cooling system is functioning properly.
  • Do not neglect the maintenance of parts such as the fuel filter and air filter.


Vehicle maintenance plays a critical role in preventing common faults. Timely and correct maintenance ensures your vehicle remains longer-lasting and safer. Additionally, regular upkeep prevents sudden failures and unnecessary expenses, enhancing your driving safety.
