Vehicle: 2024 Volvo EX90 VIN: [XXX] While driving on the highway, the entire digital instrument cluster and infotainment screen went completely black without warning. I could not see my speed, gear indicator, or use turn signals. This created an immediate and dangerous safety hazard, especially at high speed. The issue has occurred more than once, and despite taking the vehicle to the dealership, it has not been permanently resolved. I have filed a California Lemon Law claim with Volvo, and while Volvo acknowledged the defect and promised a buyback on March 18, 2025, they have failed to follow through or provide a resolution for over two weeks. I am submitting this complaint because the vehicle presents an active safety risk to myself and others, and I am concerned that this defect could result in a serious accident or injury if not addressed immediately. I also have video evidence of the blackout event. I am requesting that NHTSA open an investigation into this issue and hold the manufacturer accountable for failing to address a known safety defect in a timely manner.
