Summary Verdict
The 2006 Volvo S80, while offering a comfortable and safe driving experience, presents some potential reliability concerns, particularly with its engine and transmission systems. The turbocharged 2.5L engine can experience PCV system clogs and turbocharger issues, while the larger 3.2L and V8 engines may face timing chain or camshaft seal problems, respectively. Automatic transmissions, especially the AW55-50/51SN, are prone to solenoid and torque converter failures. Suspension components like control arm bushings and sway bar links can wear out, leading to noise and handling issues. Electrical gremlins, often related to the Body Control Module or infotainment system, are also reported. Despite these potential issues, the exterior and interior generally hold up well. Regular maintenance and prompt attention to early signs of trouble are crucial for maintaining the reliability of a 2006 S80.
