NHTSA Complaint #11595386 — 2015 CHEVROLET SPARK

Without warning, vehicle loses power and ability to accelerate is greatly reduced. The Malfunction Indicator Lamp (aka "check engine light"), the Reduced Engine Power light, and the Traction Control System/Stabilitrak light all illuminate at the same time and are not flashing. Using a diagnostic tool from a local auto parts store, code P2138 is reported as follows: Throttle/Pedal Position Sensor Switch 'D/E' Voltage Correlation, and Accelerator Pedal Position (APP) Sensors 1-2 Not Plausible. Incident has occured multiple times since owning the vehicle (approx. 13 months). This creates a safety issue because the poor acceleration limits the vehicles ability to maintain speed, especially on highways at higher speeds and ascending hills.
