Common problems while driving and how to handle them

On any car after a period of use, errors will occur. Even though there are more and more modern car models, errors cannot be avoided. Therefore, to avoid problems, damage, and risks after a period of operation, the following are error details and how to handle them.

Vehicle errors are often divided into two groups: permanent errors and random errors. Permanent errors are errors that always exist until they are resolved, while random errors are errors that only appear in certain situations and operating conditions.

In the article below, CarOn will answer your questions!

Problems encountered while driving a car

The Check Engine light flashes to indicate an error

The Engine light flashes to indicate an error

Most of the reasons why the check engine light flashes stem from engine errors. Every modern engine has many types of sensors and they are responsible for collecting information and returning it to the ECM central processor. Therefore, when no signal is received from the sensor or the values ​​obtained exceed the allowed conditions, the check engine light will light up. In addition, the check engine light may also be due to a broken or out of control mechanical component.


  • Caused by the ignition coil
  • Due to Spark
  • Fuel injector clogged
  • Fuel tank cap malfunction
  • Thermostat valve stuck,…


If you’re on the road check engine light morning warning, you should proactively respond as follows:

  • Pull over to the side of the road to inspect the vehicle.
  • Restart the car to see if the light is flashing or has stopped.
  • Check places you can see for yourself, such as the fuel cap.
  • If not, call the vehicle repair team to fix the problem.

Note: You should not continue moving the vehicle when the check engine light is on. This is an extremely dangerous situation because the vehicle may suddenly shut down.

Oil pressure is too low or too high

This problem often occurs because lubricating oil pressure can wear out after a period of use or during maintenance, providing too much lubricating oil, affecting the vehicle’s operation. Normally the pressure is only 0.5kg/cm in normal mode or 2.5 or more when the car is running. Common errors in cars also include using the wrong type of lubricant suitable for the car, which also makes the car susceptible to problems during use.

Low oil pressure


  • The car lacks oil
  • The oil is dirty
  • Not using the right type of oil
  • Broken oil pump, oil filter, etc.


– Check lubricating oil pressure when oil pressure is high

  • Step 1: Check the oil pressure sensor. Remove the sensor, install the pressure gauge and start the vehicle. If the obtained value is exactly the standard oil pressure value, it means the sensor is faulty. If the obtained value is higher than the standard value, it means the sensor is still working well, high oil pressure is due to other reasons.
  • Step 2: Check the safety valve. If the safety valve is stuck, it can cause oil pressure to increase.

– Check lubricating oil pressure when oil pressure is low

  • Step 1: Check the oil level
  • Step 2: Check the oil pressure sensor
  • Step 3: Check engine oil filter
  • Step 4: Check the safety valve
  • Step 5: Check the crankshaft bearing
  • Step 6: Check the oil pump

The car stalled in the middle of the road

The car stalled in the middle of the road

A car’s engine stalling is usually due to a problem with the operating system. In order for the engine to operate smoothly, quietly and efficiently, the precise coordination of many parts is necessary. If one of these parts has a problem, it will affect the entire operation of the engine.


  • The car’s cooling system is broken
  • Engine oil problem
  • Fuel filter clogged
  • The fuel pump/high pressure oil pump is broken
  • Fuel injector clogged…


Try restarting, if that doesn’t work, there’s no other way but to call the rescue team to move the car to the garage.

The car has a hard time starting, won’t start

A car that is difficult to start is one of the common errors in cars, especially for cars that have not been used for a long time or have been used for many years.

Car starts hard, won’t start


  • The car battery is weak and out of power;
  • The starter is faulty, causing the car to not start;
  • Due to relay or fuel pump failure;
  • Spark plugs and trick bobbins have problems;
  • Clogged material injector.,,,

To prevent errors in your car starting from not starting or having difficulty starting, you should note:

  • When turning off the car engine, turn off all electrical equipment, even the car lights
  • Replace car battery after 100,000 km or 4 years of use
  • Check and clean car spark plugs periodically every 20,000 km, replace spark plugs every 40,000 – 100,000 km
  • Check and clean car fuel injectors periodically every 20,000 km
  • Check relays, fuel pumps… periodically every 20,000 km

In case you discover that the vehicle has signs of difficulty starting, you should proactively check or take the vehicle to the garage for inspection as soon as possible.


Car tire explodes

Tire explosion is one of the common cases, this incident causes the vehicle to lose balance, leading to unfortunate accidents. A tire burst will create a loud bang, making the driver lose his temper, easily causing an accident.


  • Tire lacks air
  • Overloading
  • Tires are too old
  • Taking corners at high speed
  • Sharp objects, potholes, rocks, etc.


Step on the accelerator for a few seconds. Then slowly release the accelerator to maintain vehicle speed. Most importantly, keep the vehicle on the right road, try to stay away from the brake pedal, and steer to the side of the road to wait for an ambulance.

Loss of brakes

Car lost brakes

Brake failure is one of the most dangerous incidents, easily creating panic for the driver. The feeling of pressing the brake deeply without any effect due to the pipe losing oil, or pressing the brake but being stiff due to a clogged oil pipe or maybe the car’s brakes are locked,…


  • Loss of brake fluid pressure
  • There is air entering the brake fluid pipe
  • Master cylinder is broken
  • ABS brakes are faulty,…


Calmness is the most important factor, keep pressing the brake pedal continuously to find a chance for the system to recover, use the handbrake smoothly and operate the speed reduction technique by shifting gears to stop the car. Absolutely do not turn off the vehicle engine, this will cause the power steering system to not work, making vehicle control more difficult.

The worst situation to choose is for the vehicle to collide with an obstacle, and stay calm enough to choose a soft obstacle such as a bush or mud puddle, or if there is a collision with a hard object such as an eel or cliff, Try to keep the vehicle at a small contact angle to avoid head-on collisions.

The car has a strange smell and smoke on the hood

The car has smoke on the hood


  • Oil flows into the exhaust manifold of the engine
  • The cooling water pipe is leaking
  • Coolant flows into the engine,…


Stop the car immediately and check the car. If it is due to the above two reasons, you can continue to the garage for repair; If not, it’s best to call for help to avoid the car catching fire.

Sudden acceleration

This problem has symptoms similar to a stuck throttle, but here the cause is not due to a technical error from the engine but due to the driver’s subjective use of the accelerator pedal. Many people often panic when encountering a surprise on the road and step on the accelerator but still think it is the brake pedal, especially those using automatic transmissions.

To overcome this phenomenon, you need to try to get used to the car, do not go fast with unfamiliar cars and steps as well as with the throttle if you are still confused.
