Sorry, been busy but that was quite the ordeal. They said the track for the panoramic roof was the rattling and had to take the headliner down and take all 88 clips out to get to it. But it was supposed to take 2 days but took a week and 2 days. I never understood why didn't they just give me a kia as a rental car? I had a used cadenza before when it got serviced before but i would of even taken a optima. Also the rental was a pain had a Malibu then the bumper was falling off the second i got home, went back switched to a altima, then that had transmission issues, switched to a ford focus after waiting 40 mins in the hertz shop. Then i got a Maxima for the last 5 days since I was crammed in that focus. But once I had called for my car they said it was done I got my keys and checked and the roof still wasn't flush and my seats had marks and doors had scuff marks on each door. I didn't really understand why they thought that was ok. But I got my car back and I'm just happier then ever!
