Engine failed after owning car for only 2 weeks. Car died in the middle of an intersection. Tow truck picked it up, and dealership said that the engine harness was not properly wired. Air conditioning made loud noises when running. Dealership said that the water was dropping directly on to the 1500 degree exhaust pipe causing the loud noise. Because the heat shield wasn't properly functioning, dealership placed a pipe underneath to divert the water.
