While driving on a highway, the vehicle intermittently experienced a sudden loss of engine power during acceleration, accompanied by a flashing check engine warning light. The most serious event occurred while merging into traffic, when the vehicle failed to accelerate normally and briefly lost power, creating a risk of being struck by faster-moving vehicles. After pulling over and restarting the vehicle, normal acceleration temporarily returned, but the problem has recurred multiple times. The malfunction appears to be related to an engine misfire or powertrain fault because the check engine light flashes during the events and an OBD scan has shown misfire-related diagnostic codes (random/multiple misfire and a cylinder-specific misfire). The condition is intermittent and typically occurs after the vehicle has been driven for approximately 10–45 minutes. The vehicle remains available for inspection. The vehicle has been presented to authorized service departments multiple times for diagnosis. The dealerships have reported that they were unable to duplicate the issue during road testing and no lasting repair has been completed. The manufacturer has been contacted and the vehicle has been inspected/diagnosed through authorized service channels, but the underlying cause has not been identified. The failure continues to occur intermittently and is a safety hazard because it affects acceleration in traffic. Incident list 10/25/2025 (~12:25 PM; ~3,108 miles) — While accelerating to merge onto a highway, the vehicle lost power and the check engine light flashed. The driver pulled over, shut the vehicle off, restarted, and the condition temporarily resolved, allowing the trip to continue. 10/27/2025–11/04/2025 — The same loss-of-power/misfire behavior recurred intermittently, typically lasting a few minutes before clearing. 11/05/2025 (~8:01 AM; ~3,641 miles) — The check engine light flashed again and symptoms consistent with misfire/loss of power were present.
