The Nissan Armada is a reasonably reliable full-size SUV with an above-average rating for durability and maintenance costs. 

The experts at RepairPal have compiled data and anecdotal information on the Armada over the years. RepairPal gives the Armada a 3.5 out of five stars rating. That’s higher than the average rating of three stars for the segment. 

It isn’t the highest-rated full-size SUV for reliability, but the Armada is in the upper echelon. Other models with similar ratings include the Toyota Sequoia, GMC Yukon, and Dodge Durango

What are the common problems with the Nissan Armada?

Even with its good reliability rating, the Nissan Armada isn’t perfect. There are a few items to watch out for while maintaining the full-size SUV for the long term. 

Catalytic converter damage due to failed fuel pump 

According to RepairPal, one of the most common problems with the Nissan Armada is catalytic converter damage due to a failing fuel pump. When the fuel pump fails, low fuel pressure leads to power loss. This can affect the catalytic converter’s performance. 

Owners report that the issue tends to happen around the 100,000-mile mark. Fuel pump replacement services typically run about $2,000.

Water accumulation in the connector between the transmission wiring harness and the engine 

One vulnerability in some Nissan Armada models is that water can enter a connector between the engine and transmission wiring harness. This can short wires and prevent the engine from turning over or cause incorrect transmission shifts. According to RepairPal, this problem is mainly found in models between 2005 and 2010 with around 125,000 miles. 

Vibrations under braking 

The Nissan Armada can also develop vibrations under brake pressure. According to RepairPal, this may require a resurfacing of the SUV’s brake rotors or brake component replacement with updated parts. 

How much does the full-size Nissan SUV cost to maintain?

RepairPal estimates that the Nissan Armada costs about $550 annually to maintain. 

That’s good news for Armada owners, as a full-size SUV’s average yearly maintenance cost is around $784. The Armada’s annual ownership costs sit well below average. 

Overall, the Nissan Armada is a solidly reliable SUV with modest ownership and maintenance costs.
