Summary Verdict

The 2002 Oldsmobile Aurora presents a mixed reliability profile. While the core powertrain components are generally robust, owners should be aware of potential issues with intake manifold gaskets on the V6 and timing chain/rear main seal leaks on the V8. Transmission solenoids and torque converters are also noted concerns. Electrical gremlins, particularly with the BCM and alternator, can arise. Exterior paint and interior climate control/seat components are also areas where wear or failure can occur. Regular maintenance and prompt attention to early symptoms are crucial for maintaining this luxury sedan.
