For the Nissan Sentra B15 (2000-2006), there are several typical problems that you should pay attention to when servicing or buying a used car:

1. Crankshaft Position Sensor Problems:

This sensor can fail, causing difficulty starting the engine, misfiring, or even stalling while driving. Often accompanied by error codes on the instrument cluster (Check Engine).

2. Catalytic Converter and Exhaust System:

On models with the QR25DE (2.5L) engine, there are known cases of the catalytic converter breaking down, which can lead to particles entering the cylinders, causing serious engine damage.

3. Automatic Transmission:

Some cars have problems with the automatic transmission, especially if they are not serviced correctly (oil changes are not changed on time). This can manifest itself in jerking when changing gears or slipping.

4. Engine Mount Wear:

Engine mounts are prone to wear, especially on high-mileage cars, which leads to vibrations and noise in the cabin. 5. Suspension issues:

The front and rear stabilizer struts can wear out quickly, causing knocking and extraneous noise when driving over uneven surfaces. The shock absorber struts also require replacement over time.

6. Body corrosion:

In some regions, cars are susceptible to corrosion, especially in the underbody and wheel arches. Regular inspection and anti-corrosion treatment will help prevent these problems.

7. Electrical issues:

Some models may experience electrical failure, including malfunctions in the window lifters and central locking.

8. Ignition system issues:

QG18DE engines sometimes have problems with the ignition coils, which causes engine misfires.

9. Oil leaks:

Oil leaks may occur through the valve cover gasket or crankshaft and camshaft seals, which require attention to prevent more serious damage.

Recommendations:

• Check sensors regularly and replace them if errors occur.
• Monitor the condition of the catalytic converter, especially on models with a 2.5L engine.
• Service the transmission and suspension according to the manufacturer's recommendations.
• Check for corrosion and carry out anti-corrosion treatment.
