I just ticked over 17000 miles with my 2013 Accord EX-L V6 (with Nav). Other than the initial connectivity problems with the audio head unit they have been trouble-free. The car performs well and is capable of some excellent fuel economy. I have had highway drives of over 42MPG which is extraordinary given the 278hp V6. The 6AT trans is smooth and responsive. It has excellent fit and finish, a smooth and quiet but busy ride, reasonable handling given LRR tires, excellent interior and trunk room. The interior remains tight and rattle free.
Smooth, powerful V6 with VCM that returns excellent fuel economy with over a 500 mile range. Easily meets and exceeds the EPA 34 highway rating. The car is bipolar. with the ECO button pressed it is a docile family cruiser. With ECO off, the car comes alive and is capable of excellent acceleration. Excellent 6AT transmission (tainted by Honda's Grade Logic.) Comfortable leather seats, excellent legroom for all passengers. Clear, modern gauges and displays. Some luxury touches, ambient lighting, memory seats for the driver. Quiet interior, smooth but busy ride over rough pavement. BSM camera in right mirror. Collision Warning system.
Audio unit was unusable until Honda issued a firmware update. Still a bit buggy with Aha/iPod interface. Some wind noise around B pillars on the highway. Grade Logic is too aggressive, and uses engine braking to control your speed downhill. I have had the car suddenly downshift from 6-4th @4000RPM using CC on a mild hill. Let the driver control their speed Honda. HVAC controls are rows of buttons req. you to take your eyes off the road to adjust. Navi is bad, controls lag, voice recog. is terrible and is locked out in motion to the point of uselessness. All the electronics/smartphone integration in the car are poorly designed. My 2012 Entune sys. was much better.
