One year ago almost to the day, my daughter bought a 2013 cruze from a chevy dealership. It had 63,000 miles and now has 75,000 miles. Two days ago she was driving on the interstate. All of a sudden she lost acceleration and he check engine light came on. She was near an off ramp so she pulled off and shut the car off. The engine turned on. Her check engine light was on and blinking, her traction light was on and her message center said to check stabilizer. She tried to drive, had the gas pedal floored but car would not move. We called a tow truck and had it towed to the nearest chevy dealership. He says her ignition coil is "fried" and she needed a spark plug. But he thought that was not the cause but he had to start there to diagnose further. Authorized that. He then calls back and said those didn't fix but now she needs a new motor because the damaged coil and plug ruined her motor beyond repair because cylinders are misfiring, no fire. It seems odd to me that a car that is only 4 years old needs a new engine. This car exhibited no symptoms prior to this incident. The check engine light has never came on, the engine ran smooth, regular oil changes this past year. Any thoughts?
