good product however service sucks !!!!

I am owner of M&M Xylo E8. Infact Car is good but has below mention problems. Need to find out solution on these problems 1 Door rattling sound from all door - During service, service center given resolution by adding foam to each door, but it did not work. 2 Seats make noise while driving. Major Problem are the Service Centers of M&M 1 G3 Motors Malad 2 Global Gallery Vasai 3 Jitendra Motors Nasik All are same, Trying to fetch more and more money from the customer, Very expensive parts and Labour charges, No expertise available. Incident : There was some sound from my front wheels, I approach to G3 Motors Malad, to rectify the problem, So call expert examined the vehicle by taking test drive, and informred that joins of streeing are making noise, I asked to replace those. After 2 days, when I got my vehicle delivery, Bill generated was aroun 18,000/-, to my surprise the noise problem wasn't resolved. I just took my vehicle back and lived with the noise. on 10th-Mar-2013, when I was driving on Mumbai-Pune Expressway, after around 100kms of drive, front disc brake started jamming, fortunately I could find road side machanic who found that The noise was coming from the front disc brake, as it wasn't properly afixed. He just fixed it properly and age old noise problem was resolved, in just Rs.100/- . My Grievance to Mahindra is to have close audits and watch on dealership as those are making money with out diagnosing the problem properly and on the name of servicing they are chaning Oil/oil filters/Diesel filters and washing the vehicle. Servcing should include the checking of all problem prone parts, for re-fitting, which are lossen during the usage....Which is not done. Hope this will be taken forward.
