Indignant, when you hold your steering straight, does your car drive straight? When you let go, it steers to the left, is it immediate or gradual? What speed were you driving and where?
If it's immediate and you were doing it on flat ground on MSCP, then better kpkb TCM... otherwise, it might not be alignment.
In SG expressways it is normal for the car to go towards the left abit as the center of the expressway is higher than the sides for water drainage...
