While driving my 2007 honda element "cs", just after entering a freeway southbound, while getting up to freeway speed, a loud noise began to come from rear of vehicle as if a tire or tires were coming loose. once hitting 55mph the vehicle began to shake somewhat, yet still controllable. i pulled over & inspected the tires & wheels and could not find anything wrong. continued into next city to dealership where a four wheel alignment was done & all tires rotated. now while on cross country trip on 20 may 2012, this same issue has occurred once again on a set of new tires. the cambers cannot be adjusted on this model & year vehicle. honda has made no effort to remedy this problem. it was corrected in the 2008 models & subsequent models. the tires wear unevenly & "cup" & could cause the tires to blow, either at the same time, one at a time or even just one leaving driver in a position of being unable to control car from rapid deflation of exploding tire. i have spoken with the service writer at the dealership where i purchased my element cs & he told me honda is fully aware of this. i spoke with honda america & was told they are fully aware of this & they did not think "... this is a life threatening issue." this issue is with the honda element cs only that i am aware of. *js
