It is currently in the shop for this issue, we have only 500 miles on it, but we noticed this the moment we left the dealer...you hear this bang,bang,bang..from the rear of the car if the body leans or going over a uneven surface.
being an engineer of course this intrigues me to figure out what the issue is!
Went home..checked under the car, the exhaust pipe right before the muffler on the engine side has about a 1/4 inch clearance from a another bracket assembly.
If you grab the exhaust pipe...(cold) and move it ever so slightly...you hear it bang,rattle and see it hit against the bracket assembly.
Dropped it off this morning at the dealer and they gave the impression this is not the first time they are dealing with this issue.
Either the exhaust pipe rubber hangers are misaligned or the exhaust pipe was not bent correctly enough around the impending metal piece.
