While the Ford Fusion has had its share of strengths, there are certain model years that have garnered a reputation for reliability issues, making them potentially risky buys. Among these, the 2010 and 2013 model years stand out. The 2010 Fusion suffered from transmission problems, particularly with its automatic transmission, which could lead to costly repairs down the line. Similarly, the 2013 Fusion had issues with its power steering system, potentially resulting in sudden loss of power steering assistance, posing a safety risk. Despite these concerns, thorough research and a pre-purchase inspection can help mitigate these risks, but buyers should proceed with caution when considering these model years.
