Summary Verdict
The 2019 Aston Martin DB11 is a highly desirable supercar with a generally strong reliability record for its class. However, potential owners should be aware of specific areas that may require attention. The twin-turbocharged engines, while powerful, can experience issues with wastegate actuators (V12) or engine mounts and oil coolers (V8). The ZF 8-speed automatic transmission, while robust, can sometimes suffer from TCM or mechatronics unit glitches. The sophisticated adaptive suspension and complex electrical systems, particularly the infotainment, are also noted areas for potential electronic failures. Proactive maintenance and prompt attention to warning signs are crucial for maintaining the DB11’s performance and value.
