Of the major Japanese brands, Nissan has the most inconsistent product line. The better models deliver strong performance along with impressive fuel economy, aided by widespread use of continuously variable transmissions. Reliability for the brand is now above average, although the survey results vary widely, making it especially important to check the ratings. The same goes for road test scores; often the Nissan models don’t rank among the best in their respective classes. Don’t just take out word for it, check the owner satisfaction ratings.
