Maruti Suzuki India — faulty car juddering, and shaking engine vibration

Address:

Thrissur, Kerala, 680546

I have purchased a maruti swift vxi from brd car world on august 2016. The car was delivered from brd car world, parempadam, kunnamkulam, thrissur, kerala.
Registration number: kl-46 n 9386
Engine. No:k12mn1818628
Chassis. No:ma3ehkd1s00b35707gg
Colour: pearl arctic white
Within a few kilometers of drive, i started experiencing problems with the car. We made multiple visits to the workshop, but the problems never ended.
Following are the issues with the vehicle
Juddering of the body:
• while driving through roads having uneven surface, potholes, bumps, continuous humps etc, vehicle starts juddering, shaking and bouncing especially at low speeds. The vehicle keeps on jerking towards its left and right all the way.
• on the smooth roads like highways also a feel of instability and bad body balance could be felt while cornering, overtaking, sudden braking, bumps etc.
• while climbing on slightly inclined terrains, the car starts to sway with two of its wheels not touching the ground.
I tested with many other cars of the same make and model and i could feel that the car delivered to me was having faulty suspension, low body balance, and instable movements than the normal swift cars. Many remedies were tried such as tyre rotation, wheel balancing, suspension bush replacement etc. Recently, as per the directions from another dealer sai service, chavakkad, thrissur, all the suspension struts were changed but the problem is still prevalent (No warranty was given for the suspension change and the entire amount had to be paid).
We contacted the dealers many times but till date but they were unable to identify the exact issue. The reason for this may be they are test riding the vehicle on a short stretch of road with a relatively better surface and they are never ready for a test drive on the stretch away from their office, that we mention.
Engine vibration:
While releasing the clutch on first gear, the vehicle shows abnormal vibration than other swifts.in the first start, the engine starts to shiver and it could be felt inside the cabin also. While speeding up on second and third gears, the engine produces abnormal sounds. Releasing the clutch in a highly traffic area/ open signal in slow speed makes the engine vibrate. Upon my complaints, the dealer brd car world made a clutch overhaul replacement under warranty but the issue restarted after some kilometers
Every drive in this car has made pain on the back and legs of the driver and the co-passengers have always complained about stability of the vehicle. With the car keeping jerking and oscillating all the way, we hated every miles of drive. The measures done by the dealers have already imposed a considerable amount on me along with the loss of time.
The issue was first noticed in its second service at around 5000kms. The odometer has covered 48000 kms as on date and the issue still persists. The dealers have succeeded in lapsing the warranty period of the vehicle and the extended warranty still remains. The issue has made me feel of being cheated by the dealers. It is aware that there is no point of asking for warranty at this stage but as i intent to use this vehicle for a long period, the above mentioned issues are of high concern for me. I have lost the faith in those dealers and i request you to call back the vehicle for a detailed inspection and replace the vehicle if found faulty.
The reason to buy maruti was your quality & customer service but i feel like you have let me down. I believe my faith in maruti will be valued from your side and i expect a suitable and immediate response in this regard.
Yours sincerely,
Sujith
