Whistle noise from drivers side doors; worst gas mileage of any car I have owned *including a '67 GTO! 46K - just replaced STARTER. Water on floor mats; someone else had same problem - factory MISSED a windshield seal & dealer just over stuffed with silicone sealant. Poor side door design, R Side Passenger window regulator failure already and when going through drive throughs and any winter driving or in rain, when you put the window down - all the rain etc. comes in on power buttons at armrest. Windshield washer hoses to spray heads have both cracked and had to be replaced....
Gas mileage, side door design with armrest not getting soaked in driving rain or bad weather and you have to put the window down for tolls, or pay at a drive through window.
