When I took it to more than 90mph the car rock left to right alittle. The DSC and active steer reports no problems. Anyone knows why and how to fix? I use ContinentalTouring Eco Plus tires. Also, the tires making noises even on smooth and straight road, it sounds like the tires touching something while rolling and there's noises from the driver's seatbelt-anchor too. My A/C turns on by itself even if I turned it off, and it keeps turning on several times too. Does it have anything to do with the incar temp? or condensation that might build up if the A/C is off? is that why it turns on automatically? I took it to dealer and they said they cannot test drive the car above speed limit, so there goes the first issue. They test drive the car but didn't notice any noises from tires and the A/C didn't turn on by itself when they drove it, there goes second and third. I haven't tell them about the noise from the seatbelt but should I? the noise is like if you really softly tap a spoon to a empty tin can but it's not loud. thanks guys
