Summary Verdict
The 2002 Chevrolet Express 1500, while generally robust, exhibits some common issues typical for vehicles of its age and utility focus. Engine concerns, particularly with the Vortec V8s, often revolve around intake manifold gaskets and distributor components. Transmission reliability is generally good, though the 4L60-E can experience issues with solenoids and clutch packs. Suspension components like ball joints and leaf springs are prone to wear. Electrical gremlins, especially related to the BCM and alternator, can arise. Rust is a notable concern for the exterior, and interior components like the HVAC blower motor and instrument cluster can also fail. Regular maintenance and prompt attention to reported symptoms are crucial for maintaining the reliability of this van.
