I took my 2006 HCH in to my local dealer. I have not noticed handling problems and my tires show even wear 32K. They look like they will probably make it to 40k before replacement. He said the wear was even and not excessive; "if it ain't broke, don't fix it" and all that. He said it may start problems that were not there before it was "fixed". The dilemma is should I insist? Has anyone had this experience?
