Why is my service steering system warning on

Hello, this sounds like some kind of malfunction of the "Magnasteer" system, which makes steering effort variable depending on vehicle speed. As a result, it could be causing more binding and effort to steer. Diagnostic testing of this system is required to find out what's gone wrong. Nothing to be guessed at or suggested, other than testing. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
