NHTSA Complaint #11704345 — 2016 CHEVROLET SPARK

While driving in early 2025, my 2016 Chevrolet Spark EV suddenly lost all ability to accelerate. The vehicle remained powered on but would not respond to the accelerator, and I was unable to fully shut it off. This created a safety hazard because I could not properly control or secure the vehicle, and it required towing. I replaced the 12V battery at my own expense. The issue briefly disappeared, but the same failure occurred again within weeks. The replacement 12V battery also failed to hold a charge, indicating the problem was not related to the 12V system. I brought the vehicle to Harbor Chevrolet. Their technicians confirmed the problem was caused by a failure of the high-voltage battery system. They also informed me that the required EV battery is unavailable from the manufacturer with no estimated availability. Because this component is essential for basic propulsion and safety, the vehicle has been completely inoperable since early 2025. The vehicle is available for inspection, but it cannot be driven due to the propulsion failure. The defect has been reproduced and confirmed by the dealership. There were no warning lamps or early indicators prior to the sudden loss of propulsion. I am reporting this because sudden propulsion loss and inability to shut the vehicle down properly present significant safety concerns, especially if this issue affects additional Spark EV vehicles without an available manufacturer remedy.
