Summary Verdict
The 2012 Chevrolet Express Pasajeros demonstrates a mixed reliability profile. The V6 and V8 engines, particularly the 5.3L with its Active Fuel Management system, have documented issues like intake manifold leaks and AFM-related problems. The 4-speed automatic transmission can experience torque converter and solenoid failures. Suspension components such as ball joints and leaf springs are also noted for wear. Electrical issues like alternator failure and power window motor problems are present. However, the exterior and interior components, aside from the HVAC blend door actuators, are generally robust. Regular maintenance and proactive attention to the noted engine and transmission concerns are recommended for optimal long-term reliability.
