Why some Nissan engines score below 68/100
Nissan's cost-cutting under the Renault-Nissan alliance shows clearly in its engine reliability data. CVT gearbox issues amplify engine problems, and certain diesel and petrol units have well-documented failure patterns.
The pattern
Nissan's reliability issues track with the Renault-Nissan cost-cutting era. Shared platforms and reduced development budgets show in specific diesel and CVT-paired petrol units. The older, pre-alliance engines (SR20, KA24, VQ) remain legendary. For modern Nissan, check the engine code — not the badge.
