Engine oil consumption is the clearest pattern in 2010 Scion tC complaints. Multiple owners report the engine burning oil at a significant rate, commonly around a quart per week, without any visible external leaks. Several owners discovered the problem only after the engine had already lost multiple quarts, and at least one was told the engine needed full replacement as a result. Complaints emphasize the 2AZ engine's tendency to consume oil internally, leaving no puddles or obvious signs until oil level checks reveal the loss. Visibility complaints make up the second-largest named category, though the reports there are thin enough that no single dominant symptom stands out. The oil consumption issue, by contrast, shows up consistently across owners at varying mileage points, with some noting they learned about it only after seeking diagnosis.
