While driving at 50mph or higher, normal highway speed, it feels the car is kindly floating on the road and does not has a firm contact with the surface, on a perfectly sunny dry day. the feeling is like having tail spin a little. i've been having this experience ever since it was new, and in addition, the alignment is off from new, 1000-2000 mile new, and i always have to pull to the left to compensate. i went to dealer and reported this around 10k/15k miles, and they recommended alignment, and we did. however, problem persist. just yesterday, the rear axle just gave up and broke. i took it to the dealer for warranty service, but they refused and accused that the car's been in collision. no, no accident/collision whatsoever! and no there's not any physical damage to the tire and rim. rather, i believe this is a defect from the manufacturer. *tr
