Owner complaints4
BACK OVER PREVENTION
Owners of the 2021 Cadillac XT6 report recurring issues with the back-over prevention system, particularly with the rear-view camera. Complaints frequently mention the camera intermittently displaying a blank image or failing to show the correct surroundings while reversing. Some owners report messages like "Park Assist Block" appearing on the instrument panel, indicating sensor issues. These problems are noted at mileages ranging from approximately 7,000 to 33,000 miles. Although no accidents are reported, the failure to display accurate rear-view images presents a potential safety risk, especially when pedestrians are present. These issues are sometimes linked to a recall, but repairs are not always completed, as parts may be unavailable.
Owner complaints3
ELECTRICAL SYSTEM
Owners report recurring issues with the 2021 Cadillac XT6's backup camera system, even after recall repairs, with complaints of the camera intermittently cutting to a black screen with a crossed-out camera icon. This issue is noted as a safety concern due to reliance on the camera for visibility while reversing, especially given the vehicle's rear pillar design. Another reported problem involves the vehicle's engine failing to restart after idling, associated with a non-responsive "Press to Start" button, suggesting potential electrical or fuel system failures at under 27,000 miles. These issues present safety implications, such as limited visibility and potential engine failure, which prospective buyers should consider.
Owner complaints3
UNKNOWN OR OTHER
Owners of the 2021 Cadillac XT6 report several distinct issues. One common complaint involves the vehicle stumbling during acceleration from a stop, which occurs intermittently and has been noted to increase in frequency over time, potentially posing a safety risk during maneuvers like left-hand turns. Another issue involves the abrupt failure of front and rear vision cameras, with at least one owner indicating a mix-up regarding recall repairs. Additionally, there is a report of a sunroof spontaneously shattering while driving on the highway, described as a loud pop without external impact. These complaints highlight potential safety implications, particularly with the acceleration and sunroof issues, and suggest prospective buyers should verify the resolution of any outstanding recalls or repairs.
Owner complaints2
FUEL/PROPULSION SYSTEM
Owners of the 2021 Cadillac XT6 report issues with the fuel pump control module, describing it as faulty and prone to failure. Complaints frequently mention the module failing within months of purchase, leading to the vehicle abruptly stopping without warning. This issue has reportedly occurred multiple times, with one owner experiencing failures in traffic and near an elementary school, raising potential safety concerns. The symptoms include the vehicle shuddering, the engine light activating, and a sudden loss of power. These incidents typically occur shortly after the vehicle is acquired, suggesting a pattern of early failure. Buyers should be aware of the potential for unexpected vehicle stoppage due to this component.
