All six affected vehicles make up Nissan/Infiniti's full truck/SUV line. While the recall may seem extensive, this is likely a result of sharing components across similar vehicles. The recalled Titans, Armadas, and QX56s were all built at Nissan's Canton, Mississippi factory, and the Frontiers, Pathfinders, and Xterras came from the Smyrna, Tennessee facility.
The total number of vehicles recalled is listed as 2.14 million worldwide, making it the third largest in Nissan's history. Other reports have indicated the recall also affects international versions of Nissan's Versa and Cube, but neither has been recalled yet on the U.S. market.
According to Nissan there have been no accidents reported from the defect. The recall is described as voluntary. However, once automakers are made aware of a safety problem that fails to comply with federal standards, a recall is required under the National Traffic and Motor Vehicle Safety Act of 1966.
