Mahindra & Mahindra - Defective engine in Mahindra TUV 300

HELP; We have ended up buying a Mahindra TUV *** T*+ that nearly cost us our live. Due to defect in engine the vehicle broke down while we are on a trip. After thorough investigation, the Service center has informed that the engine has got damaged. Due to the excessive heat generated by the engine we could observe that the tail pipe (exhaust) has also melted and other parts/ components may have also been effected. Fortunately we stopped the vehicle for a pee break otherwise we could not imagine the fate we might have met. After that break, when we started the vehicle there was an abnormal sound and lots of smoke could be observe at the back of the vehicle. Further the Check Engine Light (CEL) has not even blinked once during the whole ordeal. Whereas the company profess that the TUV*** is luxuriously crafted, Hi-Tech quality, trilling power effortless drive performance, safe-inside out vehicle. But in this case the Vehicle which has been run for around **** KM (Approximately) has proved to be intrinsically unsafe and has exposed us to a lot of financial, physical and emotional loss. Keeping in view that the vehicle is in new condition, driven for **** KM (Approximately) and the financial/physical/emotional losses that we have incurred and that we may continue to incur, also considering that the vehicle has been unsafe, we have requested the company to recall and replace the vehicle. However the best response we have ever got is a call back from two different executive convincing us that we have been at fault as per terms and conditions of warranty and other conditions and that that will only repair the engine. Any one may please advise how and where to take up the issue as our request has been pending for more than one month. Early resolution is much essential as we continue to suffer the loss of business opportunities with vehicle still in service center.
