Let us discuss the most common car problems.

1. Squeaky Noise while braking

Practice relaxed braking

This car problem is very common in vehicles. When you apply the brake, there is a high pitch squeaky noise. 

 

This noise is a result of malfunctioning in the car brakes, mostly because the car brake pads wear off. 

 

The car brake pads work as a bridge between the rotor and the brakes, when the car brake pads wear off the contact of the brake and rotor is either reduced or direct. Both are not a good sign for a brake system.

 

If your car brake system is not functioning properly here is what you should do:

 

  1. Check the contact between brake pads and rotors
  2. Check the brake fluid
  3. Check the brake lines
  4. Practice relaxed braking
  5. Check the brake parts

3. Car Problems - Engine Sputtering or Misfiring

car problems - car engine Sputtering or Misfiring

One of the most common issues with the engine is sputtering. 

 

The engine functions on a mix of fuel, air, ignition, oil, and other essential elements. When there is anything wrong with the proportion of fuel and air it causes a problem. Moreover, if the spark plug is not working properly that could cause this problem too.

 

What should you do when an engine misfires?

 

If your engine is misfiring the chances are that your spark plug has gone faulty or it is dirty. 

 

Here’s how to clean a spark plug :

 

Method :1 Clean spark plug using a Wire Brush

  1. Take out the spark plug and clean the dirt using a cloth
  2. Spray some brake cleaner fluid on the spark plug
  3. Use the wire brush to clean the spark plug and clean the debris using a hairdryer or blower.

 

Method:2 Clean spark plug using a sandpaper

  1. Fold the sandpaper in half
  2. Slide the sandpaper in between the arm of the spark plug and the electrode. Keep sliding it front and back.
  3. Slide the paper between the white insulator and the electrode and clean it.
  4. Use a blower or a hairdryer to blow off the sanded areas.

 

If you find that the engine is misfiring even after you clean the spark plug, it is time to take your car to the service station and get the car checked.

4. Engine Overheating - Common Car Problems

car problems - Car Engine Overheating

Engine overheating is probably the most spoken problem. It is known to everyone. Chances are you’ve been on a long ride where you had to stop and check if the engine is overheating. 

 

If you haven’t been careful about the maintenance of your car, for instance, regular engine oil check and refill, it might cause overheating.

 

Other reasons include a faulty radiator or water pump or lack of coolant. 

 

It is worth mentioning that if you ignore Engine overheating, your car might get into more trouble and the repair expenses might increase.

 

What Should You Do When Your Car Engine Overheats?

 

  1. Turn off the heater in your car. This will start pushing the Hot Air inside the car and reduce the overall temperature of the engine.
  2. You should immediately look for an appropriate stop alongside the road and turn the engine off.
  3. After you turn the engine off, it is recommended to wait for a while like 20 minutes to let the engine cool down a little.
  4. After you think the temperature is lowered a little, now open the bonnet or the hood of the car and locate the radiator cap and carefully open it.

If this cap resists opening up, use a cloth to tightly grab it and open it.

After opening it up, add antifreeze liquid, as a coolant for your car.

 

If you don’t have an antifreeze liquid, you can proceed with water as well.

 

Pour down the coolant until the full mark on the radiator.

 

If your problem with overheating was serious, adding a coolant will not be the final solution, it will just help you get through to the nearest car repairing station.
