The 10 most common car problems and how to solve them

Identifying and Solving Vehicle Problems: Diagnostic and repair strategies to maintain vehicle performance and avoid damage.


the most common car problems

A responsible driver pays attention to the minute details of their car, ensuring its overall condition and performance are maintained for the longest possible period. Some new drivers may feel confused and fearful when encountering issues that arise for the first time in their cars. These problems may result from unprofessional maintenance or neglect of minor defects, leading to significant issues and malfunctions over time.

In the following article, we review 10 common problems that most cars face, and drivers of varying experiences encounter. Additionally, we provide a practical set of solutions to address these issues in the appropriate manner.

1.Damaged tires

Damaged tires

Special attention should be given to ensuring the condition of the tires, as the car relies on them to maintain stability and protection from slipping on the road. If you notice the disappearance or wear of the treads that are usually visible on the tire surface, continuous air leakage, or the presence of bulges and air bubbles on the sides of the tire, we advise you to immediately stop driving and use the spare tire until reaching the nearest gas station or maintenance center.

2.Battery defects

Battery defects

The car battery requires special care and daily inspection of its condition. The first thing you should check is whether the battery terminals are covered with petroleum jelly; it works to protect the battery terminals from corrosion caused by high temperatures and vapors that may occasionally escape from the car. You can also examine the battery's condition using a voltmeter or seek assistance from a maintenance specialist.

3.Front or Rear Headlight Damage

Front or Rear Headlight Damage

Imagining the severity of driving at night without proper functioning headlights and taillights is crucial. When the efficiency of these lights decreases, it indicates that they are fully consumed and have reached the end of their expected lifespan. In such a scenario, the essential step is to carefully remove the bulb located inside the lamp and replace it with a new one that is identical. It is crucial to focus on selecting the specific and suitable type of bulb tailored for your car. This meticulous attention ensures optimal visibility and safety during nighttime driving, preventing potential hazards and accidents associated with poor illumination on the road.\

4.Damaged spark plugs

Damaged spark plugs

Complications arise when the spark plugs, also known as ignition coils, undergo damage, leading to a disruption in the crucial combustion process within the engine. This disturbance can manifest in various issues, notably engine vibrations, a decline in overall performance, and a conspicuous surge in fuel consumption. As a consequence, the exhaust system may exhibit an emission of copious amounts of dense, black smoke.

Addressing this predicament necessitates regular and timely replacement of the spark plugs. It is imperative to understand that these components play a pivotal role in igniting the air-fuel mixture within the engine cylinders, influencing the overall efficiency of the combustion process.

To ensure optimal engine health, it is advisable to visit the nearest maintenance center for a thorough inspection. This step becomes particularly crucial when encountering signs such as engine vibrations, performance deterioration, increased fuel consumption, and the emission of excessive black smoke. A comprehensive assessment will determine whether these manifestations stem from malfunctioning spark plugs or are indicative of an underlying and potentially more significant issue in the engine's functionality.

5.Engine cooling fan resistance failure

Engine cooling fan resistance failure

Resistance plays a pivotal role as an integral part of the car's heating and cooling system. Its primary function is to control the rotational speed of the engine fan, ensuring optimal temperature regulation within the vehicle. However, when a malfunction occurs within the resistance component, the consequences can be significant.

In the event of a fault, the engine fan may face challenges in adjusting its speed or, in more critical scenarios, may come to a complete halt. This malfunction can lead to inadequate cooling of the engine, potentially causing overheating and other associated issues.

To address such a situation, it becomes imperative to seek the expertise of a specialized technician. A thorough examination is required to pinpoint the root cause of the problem and implement the necessary repairs or replacements. Ignoring or attempting to address such issues without professional intervention may lead to further complications and potential damage to the vehicle's cooling system.

6.Car air conditioner problems

Numerous factors contribute to malfunctions and issues in a car's air conditioning system, with refrigerant leakage in the compressor being one of the most common issues. Additionally, incorrect wiring connections pose another prevalent problem. These issues result in inadequate air cooling, preventing the system from functioning as it should.

7.Fuel problems

Fuel problems

Making it a priority to regularly check your car's fuel consumption level is essential. Any noticeable and unusual increase in fuel consumption could signify potential issues such as leaks in pipes and hoses or a malfunctioning fuel injector. Swiftly addressing these problems is crucial to prevent the wasteful loss of fuel.

8.Cylinder cap leaking

Cylinder cap leaking

The issue of cylinder head cover leakage is a significant problem that a car may encounter. Indicators of this problem include an elevated engine temperature and the emission of white smoke, especially in severe cases. Leakage occurs when the gasket, known as the 'shim,' between the cylinder head cover and the engine body is damaged. This leads to the escape of coolant, resulting in increased engine temperature or the mixing of coolant with engine oil. It is strongly advised to immediately cease driving when facing this critical issue.

9.Loud sound when braking

As a result, the squealing sound increases when the car brakes are pressed. This may be due to the presence of soil or sand particles in the brake pads that can clean the packing centers, or the brake pads may have expired and need to be replaced.

10.Brake failure

Brake failure

This is the most serious problem that can cause many accidents.

 This is often  due to a loss of fluid pressure within the brake system, where there is not  enough brake fluid in the lines to provide the required braking effect during activation.

 Another reason is that your brake pads are damaged and won't have the power you need to stop your car.

 It is worth noting that this problem can be avoided by careful and regular inspection of the vehicle's brake system.

 All of the problems mentioned in the article can be resolved with preventive measures and constant inspection of vehicle parts.

 Additionally, being well-informed, staying calm and controlling your nerves will help drivers deal with any emergency problems they may face on the road.
