Powertrain issue. Commonly a problem with the throttle body or accelerator pedal
The owners manual from my 2010 Ford Edge Limited states that you must drive the vehicle for 2 minutes at over 20 mph before the warning light will reset.
Seriously Sell the car- Honda has a design defect and will not admit it- I have a $22,000 2010 Honda CRV and the dealer does not have the first clue past putting on a new fuel cap.
