While the BMW 7 Series is generally known for its luxurious features and performance, some model years have experienced certain issues that potential buyers may want to be aware of. One notable period to exercise caution is the model years between 2002 and 2008, particularly with the E65/E66 generation. During this time, owners reported various electrical and electronic problems, including issues with the iDrive system, which controls many of the car's functions. Additionally, there were complaints about the complexity and cost of repairs, particularly for components like the air suspension. It's worth noting that BMW addressed many of these issues in later model years, so buyers may want to consider vehicles from the subsequent generations for a more reliable ownership experience.
