My 2019 GMC Acadia, currently at approximately 61,500 miles, has experienced the following symptoms:  • The engine temperature gauge remains flat or reads abnormally low/cold. • The cooling fans run continuously at extremely high speed, creating a loud \"screaming\" fan noise. • The vehicle displays the warning message \"Steering Assist is Reduced — Drive with Care.\" • The vehicle has a history of diagnostic trouble code P0128, \"Engine Coolant Temperature Below Thermostat Regulating Temperature.\"  I am concerned that these symptoms are related and represent a potential safety defect rather than an isolated thermostat or cooling-system repair.  GM has issued bulletin PIT5967, \"Service Steering Message With P0128,\" which applies to GMC Acadia vehicles from model years 2017 through 2023. The bulletin states that when P0128 is present, the ECM may be reading coolant temperature incorrectly and that a \"Service Steering Message\" may be displayed to protect the steering gear in the event of an undetected overheating condition. GM instructs technicians to diagnose and repair P0128 first.  GM bulletin 17-NA-158 also describes a relationship between P0128, an invalid coolant-temperature signal, and the \"Steering Assist Reduced, Drive With Care\" warning. The bulletin explains that the steering module relies on valid coolant-temperature information to provide additional steering assistance under cold conditions. When the coolant-temperature signal becomes invalid, this function can become inoperative, potentially resulting in a heavier-than-normal steering feel.","products":[{"type":"Vehicle","productYear":"2019","productMake":"GMC","productModel":"ACADIA","manufacturer":"General Motors, LLC"}]}]}
