I bought a 2023 gx 460 and noticed on a cold start or if the car has been sitting for a few hours and I reverse very slowly (foot still in break) the car shakes. I’m taking very slowly like car barely rolling back. I’ve taken it to the dealership and they say it seems fine but I can’t imagine the shaking like that is normal??

 

^ Can confirm this. Not every time however. Frequency is something like 3 Hz.

 

same, transmission not smooth at low speed, both forward and reverse
