Update-I took the car to the dealership and this morning for the appointment and yet to hear anything but i do have a video of said issue. its like the turbo doesnt engage until 3500rpm’s or something is restricting it. or is this a transmission issue? i have never ran into this issue before and it was 2x worse taking it to the dealer this morning (didnt get a video of it. was focused on getting to dealer safely cuz driving from a complete stop is so slow) no engine light still and im waiting to hear from the dealer. how do i add a video to this lol?

I hope the dealer figures it out. It could be many things, hard to say from here so let them go through their full process. If they find nothing, ask if they checked this bulletin for false knock detection, it's just an ECM update: https://static.nhtsa.gov/odi/tsbs/2019/MC-10166651-9999.pdf

Have they provided you with any updates? My 2019 RS started doing the exact same thing today. It’s actually quite dangerous because the car will not accelerate in a quick enough time, if needed.

The dealer fixed the issue and i wanted to post pictures of the paperwork but i sadly picked the car up after hours and had my other grab the keys and she didnt grab paperwork🤦🏻‍♂️ they told me they reprogramed the ecu and that solved my issue!:)
