Sir, i have purchased a toyota vechile (Etios liva) at radhakrishna toyota, khammam telangana state. The vechile is 6 months old. Since, i have been suffering from the ground clearance problem in it. I have complained to the service centre that, my car body is touching to ground (Road) by sitting capacity of 4 members.
But, they are not responding to my complaint they are neglecting my issue. But after that problem is arising simultaneously. After that i installed new rear wheel shocks. Again the same story has repeated (Ground clearance). As you can see that i was only one in car on driving seat, till, no weight has been applied on rear seats. The body is touching to the ground, the rear bumper has cracked. Only i am the one who is suffering from this problem in khammam. So please solve my problem immediately. (Try to not inform at khammam plz send team to khammam) my mobile no:-[protected]
