Summary Verdict

The 2012 BMW 328i xDrive is a capable and generally reliable luxury sedan. The most significant potential issues revolve around the N20 engine, particularly the timing chain guides and oil filter housing gasket, which can be costly to repair if they fail. The electric water pump is another common failure point. The ZF 8-speed automatic transmission and the xDrive system are typically robust. Electrical gremlins, such as battery drain, can occur but are often diagnosable. While not immune to problems, proactive maintenance and addressing early symptoms can mitigate most of these concerns, making it a solid choice for those seeking a sporty and premium driving experience.
