 TINY icons on the dash and steering wheel make it infuriatingly difficult to see / find / turn on / adjust the cruise control, the heater and air conditioner, etc.  Unintuitive power window controls.  I got stuck in a restaurant drive through unable to figure out how to lower the drivers window after the window controls somehow got locked up.  Key FOB has nearly illegible icons that require a lot of concentration to find and figure out.  Many times I hit the anti-theft siren alarming the whole neighborhood and then it took minutes to figure out how to turn off the alarm.  Never had these problems when renting Toyota Camry's / Hyundai's and Kia's.
