The has an intermittent problem--on start up the car will start in gas instead of electric mode. The car will rumble like an old style car in need of tune up or on bad gas in cold weather. Dealership says it needs a new cylinder head. Car is out of warranty by time but in warranty by miles. $3500 to fix a 7 year old car.
