Summary Verdict
The 2002 Chevrolet Express 2500 is a generally dependable vehicle, especially for its intended commercial use. The most common issues tend to be related to the engine’s intake manifold gaskets and the durability of certain transmission components, particularly the torque converter clutch on the 4L60-E. Suspension wear, such as ball joints and leaf springs, is also expected given the van’s load-carrying capacity. Electrical gremlins, often stemming from the BCM or alternator, can occur. Exterior rust is a concern for vehicles in corrosive environments. Overall, with diligent maintenance and addressing these known issues, the Express 2500 can remain a reliable work vehicle.
