Summary Verdict

The 2010 INFINITI M35 is a generally reliable luxury sedan. The powertrain, particularly the 3.5L V6 engine, is robust, though common age-related issues like oil and coolant leaks can occur. The automatic transmission is mostly dependable, but some instances of harsh shifting have been noted, potentially requiring fluid service or more involved repairs. Suspension components, such as control arm bushings, may wear over time, leading to noise and handling degradation.
