Hi friends, my C70 is a star parker, I always have to drive back out of my parking space (the renter wants to park in front of you ONLY), because the road is uneven, have for a few days the phenomenon that when I park out in the morning and I drive slowly back over the bumps of the road, a loud crackling noise comes from the trunk area. Whether the roof is open or closed, it always cracks, even if I drive a longer stretch straight out and then come into a curve (whether right or left) it cracks again but then no longer so loud. I drive over a badly tarred road I don’t have a single crack, I already have the suitcase room cleaned out, until the replacement wheel, but always the same game. During the day, the car is standing in the park house, when I don’t go off, I drive into the bend then it’s crisp and then it’s understandable that it’s just happened.
