My wife and brought a 2012 Acura TL base sedan with a little more than 3000 miles on the odometer in October 2012. We took on a road trip to Atlanta (Approx 900 miles roundtrip). As we were returning home the ride seem to get worse. Our average speed was between 65 and 75 mph. The steering wheel and the gas petal vibrated and the road noise got louder. The car we bought has the stock Bridgestone Turanza EL400-02 P245/50 R17 tires. What would cause the car to go from riding pretty smooth to very rough?

Tire pressure? That'd definitely be something to look at after a long road trip

Alignment? Tire/wheel balance? Along with the above all are possibilities that you may want to have looked into.
