The engine experienced a sudden failure that caused the vehicle to become completely inoperable. Prior to the failure, the vehicle exhibited intermittent hesitation, rough idling, and loss of power during acceleration. These symptoms began several weeks before the complete failure. No warning lamps were illuminated at first, but shortly before the breakdown, the vehicle displayed a check engine light and a “Service Engine Soon” message. While driving, the vehicle abruptly lost power and became unsafe to operate. I was forced to pull over immediately, which created a safety risk to myself and other drivers due to the sudden deceleration and inability to maintain speed in traffic. The vehicle would not restart afterward. A repair facility has confirmed that the engine has suffered a major internal failure and requires replacement. The estimated cost of repair starts upwards of $5,000. The vehicle is currently non‑drivable and remains available for inspection. The issue has been reproduced and confirmed by an independent service center. The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives. However, I have found multiple similar complaints from other owners reporting the same type of powertrain failure, suggesting a potential pattern or defect affecting safety.
