Cadillac XTS power steering warning display issue despite adequate fluid levels on Cadillac XTS

Some Cadillac XTS owners report experiencing a "Service Power Steering" message on the instrument cluster, particularly in 2014-2016 models, which may indicate a potential issue with the power steering system that requires attention. Additionally, some owners note that the power steering warning display can be intermittent, suggesting specific conditions may trigger the warning message. When diagnosing the issue, some report that the power steering control module may show diagnostic trouble codes (DTCs) such as C056D 3C or C0475 00, while the BCM may indicate a U0131 code, providing further insight into the problem. Even with adequate power steering fluid levels, owners find that the warning can persist, emphasizing the importance of ensuring fluid is at the correct level and in good condition. If the warning continues, some recommend inspecting the power steering system for leaks or other issues, as leaks can lead to fluid loss and impact performance. Ultimately, if the warning display issue does not resolve, it is advisable for owners to seek inspection from a qualified mechanic or dealership to accurately diagnose and address the underlying problem.
