Summary Verdict

The 2006 Maserati Quattroporte offers an exhilarating driving experience but comes with a higher potential for repair costs compared to more mainstream luxury sedans. Key areas to monitor include the engine’s timing chain tensioners and rear main seal, the DuoSelect transmission’s actuator, and the adaptive suspension components. Electrical gremlins, particularly with the infotainment and power accessories, are also not uncommon.

Regular, specialized maintenance is crucial for mitigating these issues and ensuring long-term enjoyment of this exotic Italian masterpiece.
