Cadillac XT5 reduced steering assist issue with non-functional temperature gauge and sensor on Cadillac XT5

Some Cadillac XT5 owners report experiencing reduced steering assist, which may be accompanied by a non-functional temperature gauge and sensor. These issues can arise from a faulty thermostat, which may trigger a "Steering Assist is Reduced" message on the dashboard. Additionally, if the thermostat sticks to the cold setting, it can cause the AC to stop working. Owners have also noted that problems with the thermostat, alternator, battery, steering assist system, or ECU can lead to warnings such as "Steering Assist Is Reduced, Drive with Care." In some instances, a cracked thermostat housing may require replacement to resolve the steering assist issue. Furthermore, the non-functional temperature gauge and sensor could result from internal interference within the power steering gear assembly, potentially causing grounding and damage to electrical components. It is recommended that affected owners consult with a certified mechanic or dealership for accurate diagnosis and resolution of these problems.
