1. Radiator and Cooling System Problems

Some Xterra N50 models may have radiator leaks, causing coolant to mix with the transmission fluid (aka "SMOD" - Strawberry Milkshake of Death). This can damage the transmission and require extensive repairs.

2. Rear Differential Problems

The rear differential has been known to wear out prematurely, especially on 4WD models. This can cause noise and vibration while driving, especially under acceleration.

3. Throttle Position Sensor (TPS)

The throttle position sensor can fail, causing engine management issues and rough idle or acceleration.

4. Transmission Problems

In addition to possible cooling system issues, some owners have reported difficulty shifting, especially on automatic transmission models. This may be due to electronic issues or worn transmission components.

5. Fuel Pump Failures

In some cases, fuel pumps fail, causing the engine to be difficult to start or to stall while driving.

6. Timing Chain Problems

A timing chain that is stretched is another common problem, especially on V6 engines (4.0L VQ40DE). This causes the engine to make noise and can affect its performance. Delaying the chain replacement can cause serious engine damage.

7. Electrical Problems

Over time, wiring problems can occur, especially with the lighting and central locking systems. In some cases, sensors and modules such as the oxygen (O2) sensor or the mass air flow (MAF) sensor can fail.

8. Suspension Wear

Over the years, the suspension can begin to show signs of wear, especially the stabilizer bar bushings and shock absorbers, causing poor handling and increased noise when driving over uneven surfaces. 9. Corrosion

In some regions, especially where road salts are used heavily in the winter, owners have reported problems with frame and underbody corrosion.
