Summary Verdict

The 2012 Buick Enclave offers a comfortable and spacious experience, with its primary powertrain, the 3.6L V6, being generally robust. However, potential owners should be aware of documented issues such as timing chain wear and carbon buildup, which can require significant repairs. Transmission concerns, particularly fluid leaks and torque converter problems, are also noted. Electrical gremlins, especially with the infotainment system and power liftgate, can arise. While the exterior is largely free of common defects, interior climate control actuators are a known point of failure. Overall, the Enclave is a decent choice for a family SUV, but proactive maintenance and awareness of these specific potential issues are recommended.
