I have purchased a SX4 ZXi from your dealter at Port Blair, Andaman during July, 2008 but on today i noticed a pin hole in the rear mufler of the silencer and which is liking water which is comming from the engine . I made the inspection with the authoriesed dealer on today itself and they also noticed the leak but without being hit by any thing. they also noticed that it is because of manufacturing defect. Now what I want to know is whether this part could be replaced with the new one or not . My vehicel had all the 3 free servicing and my vehicle No. is AN 01E 0888.and my name is Smti MV. Jolly, Pgt Bio, State Institute of Education, Siksha Sadan, Port Blair, Andamans. Sir If it could be replaced on account of manufacturing defect and on under waranty period which is not at all lapsed then kindly intimate it in my husbands phone No. 9434280357. Thank you. Here the agancy House, the authorised dealer had made two spots in the mufler but of no use, it still leaking soon after the vehicle is started for a few minutes. This is too bad with the SX 4 . Thank you sir.
