I'm new to the Toyota experience and hope to get some comments on a concern. Before discussing the only negative reaction I have (after 2500 mi.) I'll say that the mileage is good, 31-33 MPG with auto trans. and I like the functionality of the vehicle. My concern is handling at highway speeds, 65-70 MPH. The vehicle "floats" slightly from side to side requiring constant steering correction. It's almost like the toe adjustment is too neutral. I didn't expect this drivability problem because Toyota has very high quality marks and the XR I purchased has the optional P215/50R17 90H M&S Bridgestone Potenza tires on nice alloy rims. I assumed it would track great and have excellent feel at highway speeds with these low profile tires. Anyone else having a similar problem with their Matrix XR?
