Lincoln MKZ AWD not functioning on small snow-covered embankment on Lincoln MKZ

Some Lincoln MKZ owners report experiencing issues with the AWD system not engaging properly on small snow-covered embankments. These problems may arise due to faults in the system, such as a malfunctioning speed sensor or other components. Additionally, low brake fluid levels can prevent the AWD system from functioning correctly, making it crucial to check brake fluid as part of the troubleshooting process. In more severe cases, total brake failure can also impact the AWD system, highlighting the need to address any brake-related concerns promptly. Owners facing these challenges are advised to have their vehicles inspected by a qualified mechanic to diagnose and resolve the specific issues affecting the AWD performance.
