Engine reliability and common problems:
Until 2015, engines used to have problems with the timing chain guides, which have been resolved over time. Other problems with this engine are the oil pump performance and its drive chain, as well as cracking of the oil filter housing.Overall, this engine can last around 190,000 to 330,000 km if properly maintained, using the correct quality oil and fuel, and carrying out regular checks and maintenance.
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.

| Timing chain change interval | 100,000 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. |
