Abstract: An engine malfunction determination system includes a vehicle engine, an engine sensor system, an engine control module and an electronic display device. The engine sensor system has at least one sensor configured to detect an operation condition of the vehicle engine. The engine control module is in electrical communication with the sensor system to receive a detection signal from the engine sensor system regarding the operation condition of the vehicle engine. The engine control module is programmed to determine an anomaly in the detection signal. The electronic display device is programmed to display an indication of engine malfunction when the engine control module determines that the anomaly in the detection signal exceeds a predetermined threshold.

Abstract: Systems and methods for predicting component failure in a vehicle and alerting a driver based thereon. In an embodiment, the method includes receiving sensor data from at least one vehicle sensor over a period of time, processing the sensor data using a predictive model to detect an anomaly indicative of an upcoming component failure, determining a severity of the upcoming component failure based on at least one operating characteristic of the vehicle, and providing an alert to the driver of the vehicle regarding the severity of the upcoming component failure.
