A system for monitoring a trailer includes a detection device configured to monitor a connection between a coupler attached to the trailer and a trailer hitch attached to a vehicle and generate data related to the connection, and a processing device configured to receive the data from the detection device, and analyze the data to detect whether a partial detachment condition is present. Based on detecting the partial detachment condition, the processing device is configured to generate a notification to a driver to alert the driver of the partial detachment condition and/or control operation of the vehicle.
