Automatic shutdown inhibition diagnostics and system condition monitoring on the 2023 Cadillac CT5 are managed by battery monitoring sensors, HVAC load detectors, and engine management firmware.
How to Fix It:
-
Check Battery Charge: Ensure your vehicle battery is fully charged, as weak battery voltage automatically prevents the stop-start system from engaging.
-
Monitor Climate Demands: Note that high AC or heating loads can keep the engine running to maintain comfortable cabin temperatures.
-
Service Faulty Sensors: Consult an authorized Cadillac dealer if the system persistently fails to operate under normal driving conditions due to a stored diagnostic fault.
