Service Update. Certain 2019 model year Cadillac XT4 vehicles may discharge their battery after a remote start event and then one of the following happens: Remote shutdown, or time out of remote start, or entering the vehicle and pushing the ignition button to enter ACC or Run then pushing ignition button to turn vehicle off without ever having shifted from park. Additionally, due to a separate issue, certain Air Temperature Sensor diagnostic trouble codes (DTC's) could present themselves and indicate a condition in the ECM which can lead to a discharge of the battery as well. Dealers will reprogram the engine control module (ECM).
