2009 Toyota Prius Hatchback 4dr Hatchback (1.5L 4cyl gas/electric hybrid CVT)
Problem with highway Steering
 We brought the car for its great fuel economy and nothing else. The car isn't cute, the ride is not what we were used to but we knew that. We test drove the Prius many times before buying it.  But during our first long distance trip (400 miles) we experienced handling problems.  The car wanted to move from side to side, I was constantly adjusting the wheel. There were also cross winds during part of the trip, which made things worst.  Spoke to  my local Toyota Service department and corporate Customer Service, they indicated the car was "Working as designed". My wife refuses to use the Pruis for long distance highway driving.
