The Renault V4U 2.5-liter V6 engine was produced at factories in Japan from 2009 to 2019 and was installed on the Latitude sedan, popular in Europe, and its Korean counterparts Samsung SM5 and SM7. The unit is essentially one of the clones of the second generation of the Japanese Nissan VQ25DE engine.

Disadvantages of the Renault V4U engine
- This unit does not tolerate bad fuel and operation with faulty spark plugs.
- Because of this, catalysts are quickly destroyed, and their crumbs lift up the engine cylinders.
- It often squeezes out paper oil channel gaskets under the front cover.
- The timing chain does not differ in resource either, it is often replaced already by 200,000 km of run.
- Also, the motor is very afraid of overheating, and the water pump does not last very long here.
