I took delivery of my 2020 992 in February. I noticed that when the car exceeded 75 MPH on the highway it started to wiggle from side to side. The faster I drove the more pronounced the wiggle became. I checked he tire pressure on the information window and found that all 4 tires were at different 4 different pressures with differences of almost 5 pounds. I brought it back to my local dealer and they told me that they had put nitrogen in the tires before delivery 45 minutes later they brought me the car with the correct pressures. So off I went back to the highway to see how she ran. Low and behold that did not fix the issue so I again returned the car to the dealer. After 2 days they informed me that some how in transit the wheel alignment was out of spec and with discussions with the factory they realigned the front end.
I must say that they were on to something but I still feel the car wobbling side to side but there is no movement of the steering wheel. Now they tell me it's the highways I travel. I guess I have to move to another state with better highways to enjoy my new 992. Anybody have this issue.

When resurfacing the freeway in my area, the surface was grooved for the process. At that time, the car would follow the grooves and wiggle from side to side. On smooth roads - no problem (at least up to 130ish mph)

I do have the exact same problem. I’m taking my car for it’s first inspection 30k/km 2 years of ownership and will be back with my report.
The car does have other issues: losing PCM Connection, roof top has to be closed while driving, (it re-opens if I close it while parked, it re-closes if I open it while parked), It gives me an advice that the rear pax has not fasten the seat belt (although the seat is empty) and the wind shield wipers, the plastic door windows and roof top buttons are of low quality, not proper of an Iconic Sports Car like a 911...

Your 911 should feel extremely stable going over 150 MPH. My 992 TTS feels very straight even going 180MPH. There is definitely something wrong. With that being said, I’m not sure how much “wiggle” you have. I would have someone film behind you and see what the car is doing. Where I live, anytime I drive any car on the highway it feels like the car is swerving off to the right and left. So to an extent, I experience the same as you, but not enough to take it into Porsche and call it an issue. I would ask to drive one of your friends Porsche’s on the same road or maybe even a loaner car and see if it feels the same. If so, then it’s just the highway.
