Summary Verdict

The 2013 Audi A7 Quattro offers a compelling blend of style and performance, with a generally solid reliability record for its class. The 3.0L supercharged V6 engine is robust, though owners should be aware of potential PCV valve and supercharger belt issues. The 8-speed automatic transmission is smooth but can be susceptible to mechatronics unit or torque converter problems, which can be costly to repair. The adaptive air suspension, while providing excellent ride comfort, is a known area for potential leaks and compressor failures. Electrical gremlins, particularly with the MMI infotainment system, can occur. Overall, the A7 is a reliable luxury vehicle, but proactive maintenance and awareness of these specific potential issues can help mitigate unexpected repair costs.
