Some Hyundai Sonata owners report experiencing engine shutdowns while driving at 40 mph, which can be a concerning issue that requires immediate attention. These shutdowns may be caused by various factors, including problems with the ignition system, spark plugs, or wires. Additionally, some owners notice dashboard lights illuminating prior to the engine dying, suggesting potential electrical or sensor-related problems. Regular vehicle maintenance is crucial to prevent unexpected shutdowns. If the engine shuts down, owners are advised to check for warning lights on the dashboard, such as the check engine light, battery light, steering wheel light, and oil light, as these can indicate the underlying issue. In cases where the engine turns off and the steering wheel locks up, it is recommended to wait briefly before attempting to restart the vehicle. Clear communication with the service center, such as El Cajon Hyundai, is essential for obtaining updates on testing and diagnosis to ensure the safety of the vehicle and its occupants.
