How reliable is the Nissan Navara's engine?

I am considering buying a Nissan Navara, but I am concerned about the engine's reliability. I have heard mixed reviews about its dependability. Can anyone provide some insights?

In my experience, the Nissan Navara has a highly reliable engine. I have owned one for 5 years now and have had no major issues.

I have heard that the earlier models of the Nissan Navara had some engine problems, but the newer models have improved significantly.
