Summary Verdict

The 2014 Aston Martin DB9, while a magnificent grand tourer, exhibits some reliability concerns typical of exotic sports cars. The 5.9L V12 engine can experience issues like ignition coil failures and, more significantly, timing chain tensioner problems which require costly repairs. The automatic transmission, while generally robust, can suffer from torque converter issues. Electrical gremlins, particularly with the infotainment system and central locking, are also noted. The convertible roof mechanism on Volante models is a potential source of expensive hydraulic leaks. Owners should budget for higher maintenance and repair costs, and regular inspections are recommended to catch potential issues early.
