Confused

I just bought a 2015 Genesis sedan with 3.8, HTrac, and Ultimate package. It has 42K miles on it. After driving it for a month I feel like something is not right. When accelerating from a stop the acceleration seems very poor at lower RPM. I also hear the engine like tapping or something. I can't describe the sound very well but it feels like the engine is revving faster than it is accelerating. I thought maybe the mufflers were damaged but I took it to a muffler shop and they said the underside of the car is pristine. It is a bad experience driving it. I have to hit the accelerator hard (higher RPM) to get it to kick in. My older Genesis had a much smoother and more powerful feel off the line.

Is the 2015 just that much heavier? The car does well accelerating at higher speeds but from a stop the engine sounds like I am driving a 4 cylinder Corolla.

Would love to hear your thoughts/ideas.

Does not sound right. I had the same model and now the 2018 equal. No noise, smooth acceleration. If you have warranty, get it checked out by the dealer. If not get a good independent shop. It is a heavy car but it still has pretty good pickup. Some engines do have a little tapping on start up but goes away.

Maybe pinging? Are you using quality fuel?

Maybe it depends on what you’re used to. I thought the V6 was fine, but I got the 5.0 in the end. I think if I drove the 3.8 I would think it was slow.
