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.

The traction control light, stability light and check engine light came on while driving on a city street. According to the dealership it is having random misfires. The dealership is wanting me to pay around $350 to have the carbon cleaned out but they can't guarantee that will fix it. They said my warranty doesn't cover it. Then I asked if I go that route and it doesn't fix it, what the next step is. They said to take the engine out and clean it by hand, roughly $1000, and the warranty doesn't cover that either. I am not satisfied with their response and after reading pages and pages of the same issue in forums and no one mentioning they had to go through these steps has lead me to believe it is only putting a bandaid on the issue. I didn't buy the extended warranty just to have to dole out hundreds if not thousands.
