Excessive Road Noise ???

Question for you folks with late model Access Cabs.

I have a 2009 Access Cab and I'm getting what I think is excessive road noise from the rear corners of the cab. Is anyone else here experiencing the same?

I've had it the dealer and, of course he blew me out the door blaming it on wind deflectors I put on the driver's and passenger's windows. I wrote a letter of complaint to headquarters and the executive offices in So. California called. They pressed me to take it to a second dealer which I agreed to and they called another dealer and arranged for me to take it in. The second dealer's service tech. heard what I was talking about and they now want to test drive a similar truck to see if there is the same amount of noise. I'm waiting for a call from them.

I'm just curious if anyone here has had similar issues.

Thanks,

Norm.
