I Subhash Yadav own Mahindra XUV300 Vehicle no. HR26EH1098 registered in Gurgaon, Haryana. Mahindra have been my favourite car maker and this XUV300 is my 3rd Mahindra SUV and I have seen the standard of Mahindra services going down day by day specially in my city - Gurgaon, no doubt that Mahindra makes some of the amazing products but their services have become a real nightmare. I've sent my XUV300, 3 times to DeeEmm service center, Sector-16, Gurgaon branch but they could not resolve the below major issue of my vehicle if have tried talking to the service junior manager as we as senior manager but they are completely unprofessional people in this service center. My car suddenly stops transmission while driving from 30-80km/hr, the gear box of the car suddenly comes down to 1st gear from 6th gear losing total control over acceleration, clutch and ignition of the car. I am continuously reporting the situation to the above service center but everytime they promise me that issue has been resolved and I will not encounter this problem again but unfortunately that's not happening. Due to this condition of my SUV I have been in a very dangerous situation while driving on highways and am very unhappy with the service and unprofessionalism from Mahindra. Kindly advise what to do, because I have tried all means of complaints but no results so far. If I can't find a solution than my last resort will be a legal action. I am also attesting the proof of last 3 services. Subhash Yadav +91-[protected]
