I have a 2015 LR4 purchased from the dealership used in December. It had 8,900 miles on it. I'm currently hearing a rattle when I start the car that sounds like a heat shield. So far I've been to the dealership twice and they have tightened everything . . . it still sounds like a garbage truck. I'm going to go back a third time, but has anyone experienced this? I'd love to give them information if this problem is not just my car.

PS - It doesn't affect the driving, just sounds bad . . .
