I am reporting a serious and ongoing safety defect involving my 2024 Volvo XC90. The vehicle has experienced intermittent unintended acceleration, intermittent loss of safety and alert systems, and false obstacle detection that triggers unexpected braking or steering input. These events occur randomly and without warning, and are not tied to a specific driver, key, driving condition, or user behavior. At times, the vehicle accelerates on its own without driver input. At other times, the vehicle detects objects that are not present, causing the car to suddenly stop while reversing or swerve to avoid perceived obstacles that are not actually in the roadway. These events occur unpredictably and create a risk of collision with surrounding vehicles, pedestrians, or objects. During these occurrences, safety systems and alerts may become unavailable or inoperable, leaving the driver without audible or visual warnings. Audio alerts and system feedback have also stopped functioning during these events, further increasing the safety risk. The vehicle has been brought in for service approximately 8–9 times for various concerns, including these safety issues. Despite repeated service visits, the problems remain unresolved. Restarting the vehicle sometimes restores functionality, but the defects continue to recur unpredictably. This vehicle is used to transport young children, and these failures present a significant risk of serious injury or death. The unpredictability of the unintended acceleration, false braking/steering, and loss of safety systems makes the vehicle unsafe to operate. I am submitting this complaint due to concern for my family’s safety and the safety of others on the road, and because the manufacturer has not resolved the defect after repeated attempts. These issues have occurred since we received the car in September 2024
