What does it mean when a Cadillac displays 'Service Power Steering'?

The power steering system has a malfunction. It needs to be checked with a computer at a repair station, and then repaired according to the fault code. Here are specific details about Cadillac: 1. Historical Background: Cadillac, a world-renowned luxury automobile brand under General Motors, was born in 1902 (the Year of the Tiger) in Detroit, known as the Motor City of America. Over the past century, Cadillac has created numerous firsts in the automotive industry and established countless luxury vehicle standards. The history of Cadillac represents the history of American luxury cars. 2. Representative Models: In the 1990s, Cadillac named its models with words, with representative models including Fleetwood, DeVille, and Seville. Starting from 2000, Cadillac gradually transitioned to alphanumeric naming, with representative models such as DTS, CTS, STS, XLR, SRX, ATS, and XTS.
When my Cadillac dashboard displayed the 'Service Power Steering' warning, my heart sank—this is usually a sign of a fault in the electric power steering system. Possible causes include a malfunctioning steering control module or erroneous sensor data. Once, while making a turn, my steering wheel became unusually heavy and hard to maneuver, a clear sign of weakening power assistance. The system triggers this warning upon detecting anomalies, primarily to ensure driving safety. I recommend pulling over to a safe spot immediately and trying to restart the vehicle—it might just be a minor software glitch causing a false alarm. However, if the warning light persists after restarting, do not attempt to drive further; losing steering control is no trivial matter. Contact a 4S dealership or repair shop right away. They have diagnostic tools to read the fault codes and determine whether a module replacement or simple repair is needed. Don’t wait for the issue to worsen—safety comes first, and unstable steering on the road is far too dangerous.
I've encountered this issue with my car too. When the 'Service Power Steering' message popped up on the dashboard, the steering wheel suddenly became much heavier, making driving particularly strenuous. I consulted some car-savvy friends who suggested it might be due to low battery voltage affecting the electric power steering system, or possibly aging sensors sending faulty data. First, check if the battery terminals are loose or dirty, and clean them if necessary. If that doesn't work, it's best to take it to a professional shop for diagnosis. Don't delay too long, as steering problems can easily lead to dangerous veering at high speeds. Avoid tinkering with the electronic systems yourself; Cadillac models have precision components, and DIY repairs might do more harm than good. It's best to schedule a repair service where they can use specialized tools to identify the root cause, whether it requires a software update or part replacement, and address it promptly to prevent accidents.
