My 2017 G-80 3.3L has been giving transmission problems. When accelerating from 35 mph to 40 mph the tranny made a loud, high pitched whinning sound. At 40 MPH it shifted into gear and made a huge, loud bang noise and the car lurched ahead. Genesis replaced the tranny. Since having the new tranny, the same thing has happened twice but at a lesser scale, i.e., not as loud banging noise and less of a lurch ahead. Genesis replaced the throttle body assembly as the probable cause. I'm still having the problem intermittantly. The dealer has no idea what the problem is since all diagnostics confirm that everything is normal.
Please help if you have any suggestions. Also, do you recommend that I use the Lemon Law? I'm sure that the car would qualify.

Good luck, research lemon law in your state if it doesn't get sorted after several trips to the dealer.

BY any chance do you have a performance chip on it?

Thank you for the reply. I have no idea what a performance chip is. Is it standard with the car?
All I know is that the transmission specialist took readings while test driving and submitted them to Genesis which subsequently confirmed that the transmission needed to be replaced. Unfortunately, the problem remains intermittantly and with less of a shutter when shifting than it did prior to replacing.
I'm seriously considering invoking the Lemon Law. This is the 3rd Genesis that I've owned and the first one with any issues.

No Genesis Yet!
My '17 5.0 RWD G80 has had the following issue twice: the tranny revs 1k RPM higher when changing gears (normally happens from 2nd-3rd/3rd-4th. Dealership can't find anything wrong. I'm also experiencing rough shifting during these times. I plan on taking it to a different dealership at my oil change to complain about the issue. Very frustrating......

Just thinking out loud, wonder if they reflashed the powertrain module(s) might make a difference.

I'm at the top of this thread with the '17 G80. I took a test drive with the transmission specialist and we weren't able to replicate the problem. The dealer surmises that the problem may be from a computer issue. Since it occurs only occasionally, I'll ignore the issue. And probably won't purchase a Genesis in the future.

I think you'll find spotty automatic trans issues with many brands, Go over the the Cadillac owners site and look at the 8spd problems those folks have had on the first gen CT6....OMG
I love the 8spd in the G80
