Bought a new CRV EXL on July 1st. I have noticed that the car "shimmies" while driving (i.e., shifts right and left, especially on the freeway at higher speeds (approx. 70 mph). I feel the ride is unstable. Is anyone else experiencing this problem? I have brought it to the dealer once and they couldn't find any problem. Very disappointed as I am a new Honda owner after being a GM owner for years. What are my options if I am unhappy with what I feel is an unsafe ride? Any input would be greatly appreciated. Thanks.
