Dear Hyundai team, I purchase new xcent vehicle on May 2017, ( after 3 yrs )Now I am facing -my car music system not working, power leakage problem due to this my new battery drain out, cluster problem(power leakage) as per saboo Hyundai service center Nacharam Hyderabad. I request you to rectify my vehicle as soon as possible, Saboo servicing center charging 30K, which I don't want to pay. I ask you...such a good and big brand company Hyundai with in 3yrs so many defects, why..Pls do the needful.
My vehicle no is TS08FH2374
Purchase vehicle from Saboo Hyundai Trimulgherry .

I really trust on Hyundai brand but I think I am wrong. Very disappointed.
