Some Cadillac XTS owners report experiencing issues with the side detection system, such as receiving a "Service Side Detection System" message that indicates a failure to register vehicles in the blind spot. Additionally, some owners may encounter a warning like "Side Detection Temporarily Unavailable," suggesting that the system has been disabled due to sensor failure. Water exposure is also a concern, as it can lead to sensor failure over time, causing water buildup that compromises the sensor seal and triggers error messages on the dashboard. To address these problems, owners are advised to verify part numbers for the side detection modules, attempt to reset the system, and if necessary, diagnose and replace faulty modules or sensors. Seeking professional assistance from a dealer or technician familiar with Cadillac XTS side detection systems is recommended for accurate diagnosis and repair options.
