Bought a new Taurus and from day one the sunroof had a lot of wind noise. Dealer said it was normal. First rain, and it leaked, dealer said they all leak a little. Finally put a new one in and it was fixed. Automatic door locking is nice but when a spring popped out and sprang across to the passenger seat, I know this was a trashy car.
Terrible blind spots, NOISY as heck on the highway...sounded line the wheel bearings were bad or dry, MySync was AWFUL, and I could go on and on. So I traded it for a new Chrysler 300. Absolutely gorgeous, and not one complaint.
Sunroofs do leak. In fact, manufacturers haven't tried to seal sunroofs for twenty years. But the water should NEVER come inside the car, because when they gave up trying to seal sunroofs they switched to a drainage system.
