At first, I loved my Murano. No problems for months and months. To date, the car has not "broken down", but the engine is starting to concern me with odd noises and hesitations upon acceleration. The dealer finds no technical problems, so I am left to worry and baby the car. Also, the fuel economy is embarassing. Chevy Tahoe beats my 18 mpg by 6-7mpg. It is much bigger and it is just fine on 87 octane, where the Murano prefers 93. Whatever happened to Japanese dominance in that dept?
