Here’s a comprehensive breakdown of common issues and complaints for the 2008 Maserati Quattroporte, categorized by major components. The 2008 Maserati Quattroporte is a luxury sedan known for its distinctive Italian styling, powerful engine, and sporty handling. The 2008 Quattroporte was available with a 4.2-liter V8 engine producing 400 horsepower and 339 lb-ft of torque, paired with a six-speed automatic transmission. People often praise the car for its exotic appeal, luxurious interior, and exhilarating driving experience. However, common complaints include high maintenance costs, electrical gremlins, and a sometimes-unreliable automated manual transmission (specifically the DuoSelect). The vehicle has a wide turning radius, limiting its maneuverability in tight spaces.
