Problem Synopsis: Camera Issues in 2023 Yukon Denali Vehicle Information: Model: 2023 Yukon Denali Issue Description: The vehicle's camera system exhibits malfunctioning behavior after the vehicle gets wet, such as following intense rain. Problem Details: Initial Trigger: The problem begins when the vehicle is put into reverse after being exposed to water, particularly following heavy rainfall. Observed Malfunctions: The driver's side camera ceases to function immediately upon engaging reverse. Abrupt braking while in reverse leads to additional failures: The passenger side and forward-facing cameras also go black. Temporary Recovery: The cameras intermittently resume operation based on the vehicle's movement: Stepping on the brakes causes all cameras to go black. The cameras come back online one by one when the car rocks back, likely indicating water displacement around electrical connectors or modules. Hypothesis: The issues are likely caused by water affecting the electrical connections or modules associated with the camera system. This hypothesis is supported by the cameras' behavior correlating with changes in the vehicle's position and the presence of water. Recommendation: A thorough inspection of the camera system's connectors and modules is recommended, with particular attention to waterproofing and potential areas where water might collect and impact electrical components. Attached Evidence: The attached document contains pictures illustrating the camera issues as observed during the malfunction. These images were taken immediately after the intense rain when the vehicle was put into reverse and during the subsequent camera failures.
