Summary Verdict
The 2009 Volkswagen Eos presents a mixed reliability profile. The engines, particularly the 2.0L turbo, can be prone to issues like PCV valve failure and carbon buildup, while the VR6 engine has a notable concern with timing chain tensioners. The DSG automatic transmission is a common source of expensive repairs, with mechatronics unit failures being a significant concern. The manual transmission, however, appears more robust. The retractable hardtop roof system is a complex mechanism that can develop leaks or hydraulic issues over time, representing a significant potential repair cost. Electrical gremlins, such as power window regulators and infotainment glitches, are also reported. Despite these potential drawbacks, the interior and suspension generally hold up well. Prospective buyers should be aware of the potential for costly repairs, especially concerning the transmission and roof system, and factor this into their ownership considerations.
