Summary Verdict

The 2010 Saab 9-3, while offering a distinct driving experience, exhibits some common reliability concerns typical for its age and segment. The diesel engines are prone to DPF and EGR issues, while the petrol engines can suffer from oil sludge and ignition coil problems. Automatic transmissions, particularly the 6-speed unit, may require attention to solenoids or the mechatronic unit. Suspension components like bushings and shocks are also areas to inspect. Electrical gremlins, often related to the BCM or sensors, can manifest. Exterior rust is a concern in certain climates, and interior climate control and infotainment systems can develop faults. Despite these potential issues, many 2010 9-3s remain reliable with diligent maintenance and timely repairs, especially if common problems are addressed proactively.
