Summary Verdict

The 2012 Ford Flex presents a mixed reliability profile. The V6 engines, particularly the EcoBoost variant, can be prone to more significant issues like turbocharger problems and timing chain wear, which can be costly to repair. The automatic transmission also shows some susceptibility to harsh shifting and torque converter issues. Electrical gremlins, especially with the infotainment system and potential battery drain, are also noted. However, the suspension, exterior, and interior components generally hold up well, with no widespread critical failures reported in these areas. Prospective buyers should be aware of the potential powertrain and electrical concerns and factor in possible maintenance costs.
