Prevention: Check sensors regularly and replace them if the engine is misfiring.

2. P0300: Misfires in Cylinder(s)

Problem: May be caused by faulty spark plugs, ignition coils, or problems in the fuel delivery system.

Prevention: Change spark plugs regularly, monitor coils, and fuel filters.

3. P0420: Catalytic Converter Low Efficiency

Problem: Indicates a faulty catalytic converter or oxygen sensor.

Prevention: Use quality fuel, check oxygen sensors regularly, and monitor the condition of the exhaust system.

4. Automatic transmission problems

Problem: Overheating or wear of the automatic transmission can lead to problems with gear shifting.

Prevention: Regularly check and change the transmission fluid, do not overload the car and avoid sudden acceleration.

5. ABS system failures

Problem: Malfunctions in the anti-lock braking system can be caused by faulty sensors or wiring.

Prevention: Regularly check the condition of the ABS sensors and wiring, monitor the integrity of the braking system.

6. Cooling system failures

Problem: Engine overheating due to coolant leaks or a faulty radiator.

Prevention: Regularly check the coolant level, clean the radiator and change the thermostat in a timely manner.

7. Suspension wear (stabilizer struts, shock absorbers)

Problem: Suspension wear can lead to poor handling and increased vibration.

Prevention: Regularly check the suspension, shock absorbers and stabilizer struts, especially if you notice knocking or poor handling.

• General preventive measures:

Regular maintenance: Have your vehicle checked by a specialist, change the oil and filters as scheduled.

Quality fuel and spare parts: Using proven parts and fuel can significantly reduce the risk of errors.

Checking on-board electronics: Constantly monitor error codes with an OBD-II scanner to identify and fix the problem in time.
