This my 4th, and worst, Accord (I had a 98, 02, and 07). The Accord has never been quiet, but this one seems loud at all speeds, with an ever-present booming sound in the cabin (ANC?). The ride has improved, but it's still quite firm. It handles fine, but the steering feels dull and spongy on-center which is unusual for an Accord. Power from the I4/5AT is mediocre. It's fine at part-throttle, but always feels flat-footed when you push it. The interior is big and well-arranged, with a large, comfy back seat. The front seats are the worst of any Accord yet (the 07 had the best) because the headrest pushes my head forward uncomfortably. Terrible sound system, even my '02 sounded better.
Aux input (2011 adds USB), MP3 CD playback, good mileage (28 MPG in local driving), roomy rear seat, excellent safety features, smooth acceleration, precise steering and good ride-handling compromise for a family sedan, EX's noisy exhaust can be amusing sometimes, but obnoxious most of the time.
Lower road noise and get rid of the booming sound caused by the ANC (Active Noise Cancellation) trying to cover up the overtly loud exhaust on EX models. I4 desperately needs more torque, or less weight to haul around. Needs a 6-speed. Bring back the seats and stereo from the '07.
