Maruti Suzuki — Ertiga ZDI miscomunicate with steering & wheel

Sir I am Dr. Manjunatha N.S, from Davanagere, I own ertiga zdi reg. no KA-17 4614, brought in 29/04/y2015, got delivery at shruthi motors, davangere, karnataka. I have run around 5800 kms without any issues. i got it serviced as per the shedule. After a week (date 05/09/2015) on my routine way to my hospital i was passing over a wide good road, at 30-40kms (time:- 6.25pm), vehicle suddenly got pulled to left side and plunged into the lake side by and slowly started to drown. i tried to avoid it by turning the steering to right but didnt respond. Immediately i turned off the my vehicle & came out of from vehicle. Then i ring & inform to the shrthi motors regarding the same & they send national insurance policy related person name is shekh, by that time I arranged the crane to pull out of my vehicle from the lake. Shekh was inspected the vehicle & said that do not start the vehicle and with the help other car I reached (time :- 8.45 pm) the shruti moters workshop and handover the key to security man. Next day early morning I went to kerala for personal work & back 0n 10/9/2015 (informed to shruti motors). I visited the workshop @ 12pm & Mr.Patil check the engine & started. as the mechanic at showroom present condition of vehicle is good & visited spot where it was happened with mr. patil, Mr.Shekh & me by same vehicle. But we couldn’t get any problem with the vehicle. but my question to them was at the time of incidence why the steering didnt respond, it indicates some malfunction occurred at that time. and they dont have an answer. i have totally lost confidence on that vehicle and i have left it at showroom itself. since i am feeling show room people are unnecessarily delaying the issue i felt it would be wise to mail the matter to higher personels. Even though I called you many times but you couldn’t picked up my call. through this mail i am requesting you to intervene and solve the issue at the earliest. i will be wait for next 5 days if i dont get satisfactory solution i will be filing a case at consumer court. expecting your early responce, with regards.
