How reliable is the Nissan Navara's four-wheel drive system?

I'm considering purchasing a Nissan Navara and want to know if the four-wheel drive system is reliable for off-roading and harsh conditions. Any insight would be greatly appreciated.

In my experience, the four-wheel drive system on the Nissan Navara has been very reliable. I frequently take it off-roading and have never had any issues.

I've had a Nissan Navara for over 5 years and have put it through some tough conditions. The four-wheel drive system has never let me down. I highly recommend it.
