Summary Verdict

The 2001 Saturn LW300 presents a mixed reliability profile. The Ecotec engine, while generally robust, can suffer from common gasket leaks. The automatic transmission is a known weak point, with solenoid and torque converter issues being relatively frequent and costly to repair. Suspension components like struts and ball joints are also common wear items that may require replacement. Electrical gremlins, particularly related to the BCM and alternator, can lead to frustrating and expensive repairs. While the exterior and interior are generally free from major widespread defects, the powertrain and electrical systems warrant careful inspection for potential buyers.
