Lakshmi Hyundai — Vehicle exhaust damage

Address:

Nizampet, Hyderabad

Hi my vehicle no : TS08HG6985, I have purchased my vehicle in November and complete my second servicing at 10000kms, after second servicing my vehicle shows "diesel filter regeneration required" this is third time m facing this issue. After visiting service center (lakshmi hyundai, Nizampet)for third time with the same issue, they are saying that this will come like that no need to worry...I never excepted this from hyundai like this. It is clearly saying that there is issue in exhaust system but service center cannot understand this..
Kindly do the needful
