Summary

The 2001 Oldsmobile Aurora is prone to issues, especially considering its age. The most severe problems are related to the engine, particularly head gasket failures in the 4.0L V8, which can be very expensive to repair. Transmission issues are also relatively common and can lead to costly rebuilds. Suspension and electrical problems are less severe but still contribute to the overall ownership cost. Due to the age of the vehicle, finding parts and qualified technicians may also pose a challenge.
