Summary Verdict

The 2015 Aston Martin DB9 demonstrates a commendable level of reliability for a luxury exotic sports car. The V12 engine and automatic transmission are generally robust, though specific components like ignition coils, torque converters, and coolant hoses can require attention. Electrical gremlins, particularly with the infotainment system and parasitic battery drain, are not uncommon and can be costly to resolve. Suspension components, especially the adaptive dampers, may also present issues. While not plagued by widespread systemic failures, owners should be prepared for the high cost of specialized maintenance and potential repairs inherent to a vehicle of this caliber. Regular, expert servicing is key to maintaining its reliability.
