Summary Verdict

The 2002 Chevrolet S10 is a generally robust compact pickup, but common issues tend to revolve around its age and mileage. Engine problems like intake manifold gasket leaks and, less commonly, head gasket failures are notable. Automatic transmission issues, particularly with the torque converter clutch and solenoids, are also reported. For manual transmissions, clutch wear is expected. Suspension components like ball joints can wear out, and rust is a significant concern for older models, especially in certain climates. Electrical gremlins, often related to the BCM or alternator, can also arise. Despite these potential issues, with proper maintenance and timely repairs, the S10 can remain a reliable vehicle.
