RepairPal Certified shops can diagnose and repair your 2010 Cadillac CTS. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Check all your tires pressures. If they are ok you probably have a bad sensor. Swing by a tire shop or even costco. They can scan each sensor and see which is bad.
