Summary Verdict
The 2009 Maserati Quattroporte offers a unique blend of exotic performance and luxury. However, its reliability is a mixed bag, with potential owners needing to budget for specific, often costly, repairs. The V8 engines, while powerful, are susceptible to timing chain tensioner issues and oil leaks, demanding proactive maintenance. The ZF automatic transmission is generally robust but can develop torque converter problems. Electrical gremlins, particularly with the infotainment and power accessories like windows and locks, are not uncommon. The Skyhook suspension, while advanced, can also be a source of expensive repairs. Overall, the Quattroporte is a car for enthusiasts who understand and can afford the potential maintenance costs associated with owning a high-performance Italian luxury vehicle. Regular, specialized servicing is paramount.
