I’ve had the issue twice while flooring it from a dead stop in sport mode. It will do it with traction control on or off. I usually don’t floor it like that and prowl the anymore because I don’t want to tear up my new car but it’s kinda weird and I don’t feel it should be happening. You hear the tires spinning and just a hard thump thump thump thump from behind the dash. It’s the auto DCT trans. I use BP premium fuel and mobile 1 synthetic oil and filter. It’s a shame they make a car that they put a sport badge and a turbo in and sounds like the car is going to rip apart when you get on it from a stoplight.
