Rosenthal Landmark Honda

I purchased a used (but almost new) Honda Pilot from Landmark. Upon the purchase my wife and I stated to the salesman that the car was making an awful lot of road noise, he stated (he knew nothing about this car) that this was normal and the road noise for honda pilots was common due to the AWD. A couple of weeks after purchase we noticed the road noise getting much louder and if you let your foot off the gas the vehicle slowed very rapidly and would not just roll when driving, would slow and stop if the gas pedal was not being pushed for acceleration. We returned the car and were told the wheel bearings in the front had gone bad, at this time the vehicle had 31,000 miles on it and we purchased it with 29,000.The dealer replaced the bearings(warrantied) but also noted on the work order that the bearings had caused the tire(s) to wear excessively/improperly. After a driving the vehicle for a few more months we noticed the slow down problem went away although the road noise remained, the car literally screams when on interstate or above the speed of 50mph. We took the car back to the dealer to have the other wheel bearings inspected and check on the road noise. At this time we are told there is no problem with the car, the bearings test fine although the road noise is coming from the tire. I then asked if the problem tire(knowing this was the one with the bad bearing previously) could be isolated and replaced to remove the noise, I was told to drive the car for 10,000 more miles and just replace all the tires. I was to the point to where I would even buy a tire myself(of which I don't feel I should be responsible for) but the dealer would not supply a cost to do so. The tires are almost new and in great shape, the warranty bearing problem obviously ruined one of them, again noted on my work order. BUT, the dealer just dances and dances around the fact that this car screams like a banshee going down the road at 50mph. So, I have a nice car, it looks nice and has a nice hefty monthly payment, although if I want it to drive and sound right I need to take it to a real Honda dealer that will work with me to correct it instead of just tell me to drive it that way. This after I purchased the car here and made note of the noise at purchase time to the salesman that knew nothing about the car.
