I bought a new Maruti S-Scross zeta model 8 months back. After use of 6000 miles, I felt like my car is taking wave especially visible on the rear passenger head. When I show all of them from my car's rear-view mirror, I can see all of them are moving like a local train passenger (left to right moving head). Move head left to right 3/4 time after my car pass a single small pits of the regular road or in while taking C-turn in slow speed.
I hope this make sense to understand my issue with car behavior while observing small bump and road pits.
I want to know what is the reason behind this behavior and solution to it.
