2014 Toyota Corolla Sedan LE Eco Plus 4dr Sedan (1.8L 4cyl CVT)
Cylinder Head Replaced at 13,500, Probable Factory Milling Issue
 Bought 2014 LE Eco Plus in September of 2013.  At 13,300 miles, Code registered for fuel/air imbalance.  Service Bulletin said cylinder head and 4 valves to be replaced under warranty.  Major repair for a young car.  Very disappointed.  Toyota will not at this point extend drive train warranty for free because they have "fixed" it.  Other than that, car runs smoothly, nice and heavy for a little car.  The gray seat fabric stains very easily, even a wet gym bag or wet work bag if left on the seat too long leave pronounced stain, even with the Stain Guard extra they sell you at time of purchase.  This is a hassle, worrying about everything that touches the seats. Average 32MPG.
