I saw it here before but cant seem to find the original post, so I'm posting it again. Have your tire air pressure checked!! The previous post I saw said their car came from the dealer with 44lbs in each tire. I took my car in to a BigO today and it turned out I had 40lbs. Factory recommendation is 35lbs. so I had them adjusted all the way around and the car feels better. Not quite as harsh and the steering feels more firm and less "floaty" than before. Previoulsy it seemed like the car was all over the road and it was a challenge to just keep the car going straight. I figured it was due the hard compound of the "low rolling resistance tires" they use for better gas mileage along with the tread pattern that would cause the care to "tram-line". It turns out it was just over inflated. I've only had a chance to drive it around town since I had it adjusted, but it certainly feels better and a bit quieter too. Can't wait to get it on the freeway.
