Took car to dealer today. Finally got a tech to drive it who was not interested in just giving the company line. He said that they have had many complaints from owners of V6 camry with same problem. His explaination was that it is a design flaw caused by 16 inches wheels, heavier front end due to the V6, different suspension and wheel base. Apparently, the wheel base, tire tread, weight and suspension cause the tires to "ride the pavement grooves". Nothing you can do about it. The 4 apparently with the 15 inch wheels do not do the tracking. Am thinking about making the dealer take back the LXE and give me a 4 LE with the same equipment but not with 16 inch tires.
