After sitting in a parking lot for 6 days the radio receiver assembly (infotainment control module / head unit) in my 2024 Buick Enclave completely failed with a "no power" condition. The screen is blank, there is no audio output, no response to any controls, and the system does not power on even after multiple power cycles or battery disconnects. The dealer diagnosed the need for a full replacement of the radio receiver assembly. The part is currently on national backorder with an unknown delivery date, so the failed component remains installed in the vehicle and is available for inspection upon request. The failure disables multiple critical safety-related features, including: The rear backup camera (no image when shifting into Reverse) Audible turn-signal chimes and warning alerts Navigation system (including real-time traffic and hazard information) This creates a significant safety risk during low-speed maneuvers (such as parking or reversing) and reduces overall situational awareness while driving. The issue occurred on a nearly new leased vehicle (leased November 13, 2023) with only 54,781 miles. Yes. My authorized Buick dealer fully diagnosed the issue and confirmed the complete loss of power to the radio receiver assembly. They attempted basic troubleshooting (power cycles, etc.) with no success and determined that a full replacement of the radio receiver assembly is required. The dealer also noted the part is on indefinite backorder. The vehicle has been inspected and diagnosed by my authorized Buick dealership's service department. General Motors Customer Assistance has been notified and is aware of the issue.No inspection has been performed by police or insurance representatives. There were no warning lamps, messages, or prior symptoms. The failure occurred suddenly and without warning after the vehicle sat unused for only 6 days in a parking lot. One day the infotainment system worked normally; the next time zero power to it.
