Summary Verdict

The 2006 Saturn Relay presents a mixed reliability profile. Common issues tend to center around the powertrain, particularly the 3.5L V6 engine’s intake manifold gaskets and timing chain tensioners, as well as potential torque converter shudder and solenoid problems in the 4-speed automatic transmission. Electrical gremlins, often linked to the BCM or alternator, and exterior rust on lower body panels are also noted concerns. Interior components like the HVAC blower motor and infotainment system can also require attention. While not plagued by widespread catastrophic failures, owners should be aware of these potential repair costs and factor them into ownership. Regular maintenance and prompt attention to early symptoms can help mitigate some of these issues.
