Summary Verdict
The 2006 Chevrolet Uplander presents a mixed reliability profile. Common issues tend to center around the powertrain, particularly intake manifold leaks and EGR valve problems on both engine options, and torque converter or fluid leak issues with the automatic transmission. Suspension components like ball joints and tie rods can wear prematurely, and electrical gremlins, especially with the Body Control Module and power sliding door motors, are not uncommon. Interior climate control and infotainment systems can also develop faults. While not plagued by widespread catastrophic failures, owners should be prepared for potential repairs in these areas. Regular maintenance and prompt attention to early symptoms are crucial for managing the long-term reliability of this minivan.
