Infiniti FX 2012 30d engine V9X
Engine reliability and common problems:
The V9X engine stands out due to its unusual 65-degree V-angle. It features a lightweight cast-iron block, aluminum cylinder heads with hydraulic lifters, a variable geometry turbocharger, and a chain-driven timing system.It delivers immense torque and impressive pulling power while maintaining relatively low fuel consumption. For a diesel engine, it also has remarkably low noise and vibration levels.
However, reliability remains a key concern. One of the most critical issues is bearing failure, which occurs if the oil pump's performance drops. Timing chains tend to stretch by 100,000 km, and excessive oil consumption often develops due to stuck oil control rings. Cylinder scoring is also common.
Other weaknesses include frequent EGR valve clogging, high maintenance costs, and leaks from the front cover. The intake system tends to accumulate heavy carbon deposits, further affecting performance. The single-row roller timing chain typically lasts 130,000–150,000 km before showing signs of wear. Overheating and oil pressure drops can lead to piston damage, while the compact design combined with high power output makes the engine prone to bearing rotation, particularly if the oil pump fails.
Additionally, intercooler leaks often occur around 50,000 km, leading to oil loss. The component is not repairable and must be replaced. The engine is also known for oil consumption issues caused by weak piston rings, which can eventually lead to excessive exhaust smoke.
The engine has hydraulic valve tappets (lifters), which provide quieter operation and do not require periodic adjustment, but are more complex in design and can cause serious engine damage in the event of failure.

| Camshaft drive | Timing chain Chain motors are considered more reliable, chain replacement usually is required less often than a timing belt, but they are often louder and vibrate more. More service info |
| Timing chain change interval | 150,000 km (recommended) Sometimes manufacturers do not specify timing chain replacement intervals and design chains for engine life. However, once the recommended change interval has been reached, it is recommended to periodically check the condition of the chain and to change the chain if excessive stretching is detected or if unusual noises from the engine or other symptoms occur. |
| Fuel system | Common Rail Common rail fuel injection provides more engine power, is quieter, more environmentally friendly and offers better fuel economy, but is more expensive to maintain and repair. |
