One problem related to check engine light on has been reported for the 2013 Honda Insight. The most recently reported issues are listed below.
Traveling 65mph on highway with cruise control on. Lost power and check engine light came on. I pulled to the shoulder, engine continued to run, but would not accelerate. Turned car off and back on and multiple check messages displayed. I had car towed to local Honda dealer shop. They informed me spark plugs needed to be replaced. I agreed, but next day they called to tell me the entire engine needed to be replaced. Honda has extended the engine warranty, but no one from dealer mentioned that. They wanted more for new engine than the car is worth.
