Sir I had a similar issue with my GLi, the issue was since day 1.
I took it to the dealership and complained about this and as the car is under warranty they were bound to correct it.
The guy fully turned the steering towards left and did some adjustment behind the right wheel without removing anything, same thing for left wheel, loaded car on to the lift, adjusted the brakes and rotated the tires. Then I went for a test drive along with their technician and I floored my car on 7th Avenue and then braked hard, the issue was gone.
We should expect such quality issues from Pakistani assembled cars.
